How to lay a water pipe under the ground. The use of simple techniques. Which pipes to use

For living in a private house, when a person has the opportunity to enjoy peace and solitude, the opportunity to spend time in a comfortable local area, how not to twist, but have to pay. In this case, we are talking about the responsibility that the landlord bears when constructing life support systems. After all, if the owner of an apartment in a multi-storey building completely relies on the work of the corresponding communal services, then the owner of a private house has to answer for everything himself. For example, take a water pipe. What determines its functionality and performance in all weather conditions? The answer is simple: everything will be fine if the water pipeline is laid correctly in the ground. On what to do with device of an autonomous water supply system in a private house   we will dwell in more detail in this article.

Naturally with the development of the project. And let it not be professionally work with appropriate design, but all the same, the key parameters of it should be reflected. First of all, it is necessary to pay attention to such circumstances:

• looseness and softness of soil - it is this that determines the choice of material for the installation of a water pipeline;
• the area of ​​the territory on which the water main will be laid - is needed to determine the number of inlets and branches.

Which pipes to use?

The depth of the water supply is the most frequently asked question, which is asked by people who decided to install this system with their own hands. The answer to this question must first of all begin with the definition of the type of pipes used. It is their quality parameters that are key when laying a water pipe into the ground. Practical experience shows that the best option   for today is the use of HD10 PND pipes. That is, pipes made of polyethylene low pressure, authorized for the implementation of the drinking pipeline.

Pipes of this type have such technical characteristics:

• are not subject to corrosion, like metal elements;
• can withstand a pressure of the order of 10 atmospheres;
• have high strength characteristics;
• easy to bend;
• perfectly behave in freezing cycles.

The quality of the gutter is affected by the structure of the soil

Be careful! For sale there are cheaper pipes of PN 6. Do not risk and buy material at a lower price, otherwise in the process of operating the pipeline, there will inevitably be problems.

Special pipe   for laying water in the ground

In addition, HDPE pipes are characterized by quick installation and inexpensive fittings. Although a water pipe of other materials also has a right to exist. Here everything depends on the preferences and possibilities of the owner of the house.

What is determined by regulatory documents?

In order not to guess at what depth the water pipe should be laid, it is necessary to turn to SNiP. It is this normative document   regulates all technical points, including the depth of the underground underground communications. According to the norms of the pipe should be laid to a depth of not less than 1.6 m. And this parameter is determined by such circumstances:

• The depth of freezing of the soil is within 1.4 m, so if you make a trench less than 1.6 m, it is guaranteed that the water in the pipe will freeze and use a running water will be physically impossible for a certain period of time.
• The degree of freezing of the soil depends on the location of the home ownership. As an option - contact a local construction company for advice. Such enterprises carry out works all-the-year-round, which means that they will accurately prompt the depth of freezing of soil in a particular locality.

According to the SNiP, the depth of the water supply must be at least 1.6 m

Attention! The ground below the 1.6 m mark does not freeze, the temperature at this level is always positive.

The problematic moments when laying water in the ground

The most big problems   arise when the soil structure does not allow digging the trench to the required depth. How to be in this situation? The trench needs to be dig as deep as possible. Then perform the laying of pipes, pre-performing their thermal insulation. In addition, an obligatory measure aimed at ensuring full functioning water supply system, in winter it is the installation of a heating cable throughout the pipeline. Of course, this method of constructing a pipeline requires considerable material and labor costs, but sometimes it is the only correct one when installing an autonomous water pipe.

Note! Even if the water pipe is installed in a territory with a mild and warm climate in winter, the paved pipe can be damaged too much as a result of mechanical stress. If the pipe is buried very deeply, it can not withstand pressure and will simply crack.

If you are sure that you have taken into account all the circumstances and carried out the laying of the pipeline in accordance with all norms and requirements, all the same, before you fill the trench, test the water. Turn on the water and follow all the way to make sure there are no leaks and tightness of all the units. Only after this can be considered the process of laying water pipes   complete.

Buyers are increasingly choosing pipes on a polypropylene basis. The products are highly demanded that provide operational characteristics, no problems with installation, an affordable cost indicator.

Producers say that they serve not less than 50 years. Enough and minimal skills in order to perform such work as laying a water pipe from poly propylene pipes   in the earth.

The first stage in any installation of the water supply system is to dismantle the sections of the old pipeline. Steel products often require replacement in full.

Mounting with the help of Bulgarian is the most convenient and simple solution. After this, proceed to laying polypropylene pipes of a new water pipe.

Rules for laying in the ground with your own hands

GOST says that for laying in the ground, pipes are required to have diameter not less than 32 millimeters. For convenient and quick installation   a set of fittings is purchased.

  This sequence of actions is performed,.

Normative documents: conditions and requirements of the pipeline

Norms determine the laying of any pipeline, regardless of what material it is from. Many technical issues are regulated in the so-called SNiPs.

  They provide security, allow you to carry out any kind of work. Here are a number of requirements that must be fulfilled for laying in the ground.

1. Accounting is required for the point at which the ground freezes. Its level is often 1.4 meters. In winter, the water inside the aqueduct simply freezes, if it is below. The operation of the water supply will become impossible.
2. The gasket and its method will vary depending on what structures and structures are already present on the territory. And on the availability of highways, communication networks, trails. It is better to turn to specialized firms, if there is no complete certainty about where to conduct the installation.
3. The features of the ground and relief are important for those who are laying water under the ground.

Possible problems

Sometimes it happens that the structure of the ground does not allow digging the earth at the required depth. Or ground freezing of the earth occurs with such force that the water pipe is damaged.

But the output can always be found. For example, to make a puncture if the earth is caught too loose. First, a steel pipe is laid in the hole, and a polypropylene pipeline is installed inside it.

Anti-frost protection - heating cables placed along the entire length. But such work is associated with additional costs.

Trenchless methods of laying, finally, will be an excellent solution for those who have encountered an obstacle that can not be bypassed.

Features of trenchless laying

Trenchless installation gives owners several advantages at once.

• There is no need to destroy buildings or plants that stand in the way.
• To a minimum, damage is done to the environment.
• Time and financial costs are reduced.

There is more than one method.

1. Sanitation. It means that old pipes are changed to new ones. Works are carried out in two ways:

• Relining. Inside the old pipes lay a new, polypropylene. The main thing is to see the pipeline in advance. The main thing is to make sure there are no foreign objects and debris. It is also important that the diameters match each other.
• Renovation. A new pipeline is being laid and the old one is being destroyed simultaneously. It is carried out in situations where the original diameter is insufficient.

1. Piercing. Actual for diameters over 150 millimeters. The work has several stages.

• Two excavations are dug from both sides of the object, under which we will conduct communication.
• Place hydraulic jack on one side. He pushes a polypropylene tube with a steel tip.
• The pipe gradually increases volumes, and then polypropylene products are introduced into it.
• Connection to all systems.

But the latter method is suitable only for those who are interested in laying small lengths of water pipelines.

What about warming?

But additional protection is often required when laying outside.

For this purpose, for example, special cases are used. The existing water pipe is laid inside another pipe, with a small diameter. What contributes to the formation of an air cushion between the walls of different products. Thanks to this, the heat of the water is preserved.

  Either the pipeline is simply poured using polystyrene concrete or foam concrete. This is a monolithic layer, with a base in the form of concrete with a small weight and a porous structure.

Or a heating cable. The latter is laid both inside and outside the structure. The gasket is recommended to be carried out in two ways:

1. Two lines parallel to each other.
2. Spiral, around the aqueduct.

Not every system is designed in such a way that the pressure in it without problems increases. But this method of protection is able to boast of efficiency.

When stored internally high pressure, the liquid does not freeze. Even if there is no physical insulation.

When installing outdoor non-pressure varieties of sewer use the so-called connection in the socket. The main thing is the absence of impurities on the plastic, then the joints will acquire high tightness. Silicone or liquid soap lubricates the parts requiring joints.

Sealant treatment will provide additional protection during such work as laying a water pipe made of polypropylene pipes in the ground.

Only compliance with all the requirements and technologies will allow obtaining a water supply that will function for a long time. And will help reduce operating costs.

We are engaged in the installation of filters

If there is no scales or sand in the water, then much longer live items such as fittings on toilet bowls, washing machines with automatics, mixers from ceramics.



  It is enough to install the simplest filters, with rough cleaning. Without water treatment filters, it is not advisable to lay the polypropylene pipes by oneself.

Do not give preference to filters that are parsed manually. Inside such structures are rubber seals, whose durability leaves much to be desired.

The preparation process depends on which type of pipe you have chosen. If it's galvanized, then we use the Bulgarian to cut the blanks of the sizes we need with our own hands. You can also do this with a hacksaw.

Metal-plastic or polypropylene products are more convenient to cut at once in place. Even small misses in size will not be terrible.

When joining, preference is given to two methods. For example, through a collector that plays the role of wiring for individual devices, when each of them has its own reinforcement. Or through a simple tee.

We work with steel products

With appropriate tools at hand, for example, such as welding, it is used to connect the structure from metal.

A water pipe in a private house or on a land plot is one of the benefits of a comfortable life that can be built without the help of professionals. The laying of a water pipe in the ground in particular does not present serious difficulties, but requires attentiveness to detail and strict adherence to the course of work.

In this article we will consider:

• how to make the right choice of pipes;
• how to build a water supply system by the standards of SNiP;
• how to avoid the main problems;
• as .

And we will talk not only about household water supply (intended for pumping drinking water), but also about irrigation (irrigation) irrigation (irrigation) system of plants in the garden or on a private plot.

Technical Foreword

To morally (and not only) prepare for the work, of course, you need to learn a little general theory.

There are two ways of laying a water pipe: on the surface and under the ground. In this article we will consider the latter option.

Pipeline laying is carried out by one of three methods:

1. Excavator digs a trench, the rest of the work is done manually. It takes a lot of special equipment.
2. Horizontal drilling (HDD), trenchless technology. Puncturing the earth.
3. Shield gasket - this method is called collector. The structure of tunnels for communication.

Technology in each case is different, we will consider in this article a method that can be done with your own hands (shovel instead of excavator, drilling).

Variety in the choice

Pipes are made from various materials (even from wood) and their combinations (for example, from aluminum and polymers), since this product is used not only for water, gas, sewerage; but also in construction (metalwork), and in mechanics. Therefore, it is so important from all the variety presented in the sale, to know exactly what is ideal for your purposes.

For a water pipe, steel welded or seamless pipes. They, in turn, are divided into classes: for carrying out gas, oil, profile and seamless - this is what you need for laying in the ground. Among them, preference is best given to galvanized (coated with a layer of zinc), they are more resistant to corrosion.

For the connection points, the pieces (hose) are used. They can be reinforced (with reinforced additive) and corrugated. The cheapest option is conventional pipes.

Of course, the pipes differ in weight, length, diameter. GOSTs determine the required diameter for an underground water pipe, and you can make a choice of wall thickness and length yourself (from what is on sale).

Also different pipes of different pressure are distinguished.

As for materials for the water supply, use cross-linked polyethylene, copper, polypropylene, stainless steel and galvanized pipes.

Yes, the choice is huge, but on what all the same to stop? Let's turn to the choice of the majority, the market leader and the favorite option.

The best choice

For works that are waiting for us, you can choose (plastic). HDPE:

• do not rust;
• maintain sufficient pressure (PN10, not PN6);
• stronger than them and not required;
• carry frost, under the influence of temperatures stretch due to its elasticity;
• well bend, so comfortable in the gasket;
• available at a price (30-35 rubles).

The pipe for laying water in the ground should be 32 mm in diameter, 2.4 m in length - this is GOST 18599-2UUI. To it you need to buy fittings for simple and quick installation, no tool is required. Fastening reliably, will not flow.

Stages of construction of water supply system

All works will be held in the following sequence:

1. Dig a trench depth of 1.8 m, for the north of Russia - more than 2.5 m. Remember these recommended standards. They are associated with the freezing of soil, at this depth the temperature in winter reaches -17 and even -20 C. This indicator varies from the duration of frosts, from the characteristics of the soil itself (density, humidity). But craftsmen advise to dig deeper (2 m), just in case. The width of the trench is 0.5 m. Do not forget about the construction of the gradient.
2. The withdrawal from the house through the foundation. If it is monolithic or from blocks of PBS, a punch is required. You can buy a professional with a drill for 40 or a low-power household for 24 mm. Drilling in the latter case will take more time - 3 hours. The mode is set as follows: 4 strokes. And then, having reduced the drilling regime by half, from the side of the trench. The thickness of the hole should be 50 cm to pass the pipe.
3. Protection. Water in the pipe should not freeze. On sale there are heating cables. They are very expensive. Therefore resourceful craftsmen lay the field cables P-274. Inside, they also have veins (copper, steel), which create a "heating" effect. It is connected to electrical network, but not 220 W, enough 36 W to heat up to 60 C. The right voltage is obtained through a transformer (power supply). The instruction for its installation is not complicated: the cable is wound on the pipe, a step of about 10 cm. The end of the cable must be sealed by connecting it to the beginning using a terminal strip. Start the connection.
4. Mounting sensors. This is an optional action, but very useful. Only three sensors (40-70 rubles) along the pipe, and you will know about the temperature of the ground, and therefore, you can affect a specific point. The fact is that modern sensors are equipped with automation: when the temperature drops to the specified mark, heating is turned on. They can also be connected:

• to the notification system that transmits information about changes in temperature and the activation of heating to the voice device or even to the phone in the SMS;
• master of the network (it is equipped with a special program that connects all the elements of the system into a single whole).

The sensors are inserted into heat-resistant tubes. The sealant is also used for protection. Apply plastic glue on top.

1. Warming of the pipe. This is a mandatory procedure, even if there is expensive heating cable and sensors. No master making a water pipe for himself, will not dig a trench until he covers the pipe with a heater. It increases the efficiency of the heating system, protects water with a prolonged absence of flow (if suddenly the owners left). So, the pipe is covered with a thick (13 mm) layer of special insulation, for example, inexpensive (25 rubles per meter) and a quality Energoflex.
2. Isolate from ground. To protect the pipe and cable from the mechanical action of the ground, the craftsmen are advised to put them on top of sewage pipe. In the joints, insert the rubber sealing rings. So you will protect and a layer of a heater from getting wet and "karyabanija" a ground, and the pipe. So you can reduce the depth of the trench to 50 cm and protect the water from freezing to -20 ° C.
3. We finish the installation of the pipe in the trench. The beginning of the pipe is pushed through the hole in the ground. The end is fixed in the well or borehole.
4. Testing the system. We connect to the network through a transformer, we control the sensors and make sure that everything works, that everything is done qualitatively and safely (the cable does not melt, the pipe does not burst and does not flow when heated).

Possible difficulties

Experts note a number of problems that everyone may face:

With all the rules and advice of the masters, the system will last you for many years.

Features of the watering system

Its creation will require the construction of entire highways. Their length, frequency of use and power will determine necessary materials, scheme of work.

The technology of installation of the system requires the development of an individual project. Make a simple and understandable scheme for yourself, on which you must find your place:

• plants (lawn);
• trenches;
• place on the scheme structures and areas that you do not need and should not be watered (move the entire irrigation system away from them);
• automatic irrigation system (or pump);
• we place on the entire length of the trenches sprinklers, valves and controllers.

Next, in the first place, we also prepare trenches. Direction, width (usually 50-60 cm) and length - according to the project. Stock up with a roulette and construction level. At the bottom of the trench lies sand 10-15 cm thick, it is watered and tamped. Then we take also polypropylene pipes, fit into the trench, their ends are brought to the source of water. The necessary components are connected to the system: pump, filters, pressure regulators, valves, sprinklers and controllers. Watering your own structure is ready.

Setting up a water pipe in the country, in the garden, on the countryside or in a private house, we can build a watering system or a system of water supply to the house. In any case, the work will be carried out according to the above scheme. And laying a water pipe in the ground will require you to be ready to perform all the recommended works. But in the end, you get the ideal result - a smoothly working system for supplying drinking water to the house (or irrigation).

No modern a private house   It does not do without a pipeline that fits into the ground. Any system of water supply requires special treatment. In this article we will talk about how to lay a water pipe under the ground, and about the nuances that can arise in carrying out these works.

Any type of water pipe, if it is laid with observance of all norms and requirements, will turn out to be of high quality, and will serve the entire allotted life with maximum efficiency.

  Initial stage of work

Any laying of water pipes begins with the design of the project. The scheme should be worked out qualitatively, otherwise the pipeline system will not be able to function properly. This does not mean that the project should become a miracle of engineering thought - the main thing is that you easily orient yourself in the finished scheme so that when errors occur during the work you can easily understand and quickly solve them.

The project must contain such information:

• The properties of the soil are its type, loose, stony or sandy.
• The area of ​​the ground along which the pipe will be laid. It is necessary to calculate, so that you can always consider the number of forks and entrances.

Remember that the laying of water pipes must pass through a pre-aligned area. Ignoring this nuance can lead to unexpected bad consequences in the near future.

  Water pipe laying depth

Of course, in order to correctly perform the laying of pipes underground, many conditions must be taken into account, because any deviation from the norms can lead to malfunctions in the operation of the entire water supply system. For example, when deciding how deep the pipe can be in the ground, it is worth taking into account the material from which it was made.

In addition, it will be necessary to study the individual characteristics of each variety of pipes in order to understand in which cases it is expedient to apply this or that type of product.

As practice shows, the optimal pipe is considered to be a water supply for a private house underground "PND PN10", made of polyethylene.

Products of this type are characterized by such qualities:

• absolute non-compliance with corrosion, unlike metal analogs;
• the permissible operating pressure in the system is 10 atmospheres; moreover, such pipes can be easily bent to obtain the desired configuration;
• resistance to temperature changes during the season change of the year.

  Subtlety of underground laying of water pipelines

When it comes to the ground part of the aqueduct, it is necessary to give priority to products that are strong enough and reliable to successfully withstand temperature and pressure changes. In this case, the type of pipes described above, another advantage of which in the convenience of mounting with fitting fasteners, is perfect.

And to make it easier to determine which pipes for plumbing in the land are best suited in each specific case, it is worth paying attention to the available ready-made water pipeline projects, tested by practice, and also to take into account the requirements of technical standards. With this approach, you get a non-waste and high-quality water pipe, and laid without much effort.

  Technical standards for buried systems

You can find out how deep the pipe should be for the water pipe in the ground, from a special document - SNiPa. There, all the details and characteristics for pipes of various materials are prescribed, as well as it is laid out at what depth it is possible to lay this or that type of products. In essence, this document contains a lot of various information, most of which will be to you, if not very interesting, then at least useful, because it will remove a lot of related issues.

According to the EPA, the minimum depth of laying of any pipe is 1.5 meters, because, often, in winter the soil freezes by about 1.4 meters. If you do not comply with this depth, you can face damage to water pipelines, which makes it much more difficult, if not impossible, to continue operating the system.

It is worth noting that the depth of freezing largely depends on the type of soil in a particular region. To find out exactly this indicator, it is worth to consult with specialists who will prompt you all the necessary information that you need to know. Armed with information, you can avoid the many possible problems associated with temperature changes and ground freezing.

Nevertheless, if you do not have the opportunity to get professional advice, then just make the trench a bit deeper. Paving the pipes 1.6 meters from the surface, your water supply will be protected from any surprises related to strong winter frosts.

  The most common errors for underground pipelines

Underground laying of communications, naturally, largely depends on the type of soil in a particular place. And, often, many difficulties arise with it, while the composition of the soil may simply not allow the pipes to be deepened to the distance laid in the SNiP. In particular, the soil can be very dense, rocky or swampy, so you simply can not get to the required depth. In this case, in winter, many difficulties can arise.

It is worth noting that to insulate the water pipe will be absolutely superfluous in any situation, even if you can max out the system as much as possible. One of the best options for insulation is a gasket along the heating cable pipe.

Nevertheless, this method is not cheap at all and is associated with significant financial and labor costs. But still it is considered the most reliable. Of course, doing all the work yourself, you can save a little, and even get some experience that may come in handy in the future.

  Methods of warming

Perform work on the insulation of pipes for water is necessary, because at low temperatures the water will freeze, and the system will stop working. Therefore, it is important to make every effort in advance to prevent such troubles. Especially it concerns the ground part of the pipe, which runs along the street and over unheated premises.

To determine the right material for the performance of insulation, it is worth considering the following factors:

• in the private sector, all construction works   the owners, often, produce independently, the process of installing the heater must be as simple and convenient as possible, so as not to create difficulties for beginners;
• a long service life of products, which will allow to do without additional measures as long as possible;
• incombustibility of the material and its fire safety;
• creation of a sealed coating;
• the correct ratio of quality and price of the material, which is very important.

So, considering all listed factors, the heater should correspond to such parameters:

• low thermal conductivity;
• ability to absorb moisture well;
• resistance to environmental influences;
• resistance to temperature fluctuations.

All these indicators are decisive when choosing optimal material   for insulation of pipes. By and large, there are few types of insulation materials, so choosing something suitable is not so difficult.

If the installation of a water pipe is made of metal-plastic pipes, then the choice can be stopped on the fiber. It has a small density, which is its main advantage. However, this material requires additional insulation, which significantly increases the duration and cost of work.

Basalt cotton wool is characterized by good quality characteristics and convenient way of laying, however, such a heater is quite expensive.

Styrofoam is an excellent material for insulation, it is very popular among consumers. It can be used for both external and internal works, and the strength of the material allows its reuse in case of dismantling the system for repair, for example.

To make stacking of expanded polystyrene, the shell must be divided in two, first put the first part on the pipe, and then the second - overlap. After installing all the insulation elements, the joints must be sealed with several layers of adhesive tape. Shell shaped type is very convenient to use during work with corners and turns in the water supply system. Thus, in the insulation of pipes with the use of expanded polystyrene there is nothing difficult - even a beginner will cope with work.

To disassemble the layer of this insulation, all these manipulations will have to be done in the reverse order.

So, in conclusion, we can say that, provided all the rules and regulations for laying underground utilities are observed, you can get a high-quality and durable water supply system. Note that when piping water for the house, do not rush to fall asleep trench. First, it is worthwhile to conduct a trial run to exclude any problems and correct them in time. In the end, you need to again carefully inspect the joints, make sure that everything is working correctly. Only then can the work be considered complete.

Winter water supply for a country house   - the only way to ensure a comfortable stay all year round. For this, in any case, the laying of water and sewage in the street - external or domestic. Despite the fact that the water pipe can not be called a dangerous or complex engineering system, its installation also requires knowledge of certain norms and rules. Only their observance guarantees long service   without gusts and freezes, as well as the purity of drinking water and the stability of the declared head in the project. But all of them do not require special equipment or equipment, and it is quite possible to make such a pipeline on site with their own hands.

How to make a water supply in the country: the width of the trench and the depth of the laying of water pipes

The first thing you need to take care before making a water supply is obtaining all the permits. If it is a question of connecting to a central water supply system, then this should be a full-fledged project indicating the location of the tie-in and the working head of the system. Many organizations that serve such systems insist on carrying out a tie-in with their staff specialists. For autonomous water supply, this permission is not required. In addition, it is necessary to check the site in the places of trench digging for the presence of already laid communications (communication and power cables, gas and water, sewerage). For this, the site plan must be provided to the appropriate institutions, where they will mark the places of passage engineering systems   and depth of occurrence.

After that, you can proceed to the trench digging. At the intersection of the pipeline with other communications, excavation works are carried out manually, in other areas, special equipment is allowed. The width of the trench when laying the water pipe SNiP is regulated only for large diameter pipes or at a depth of more than 3 m. Such cases in private construction are not considered, therefore, when handmade it is usually done 0.5-0.8 meters, and when using special equipment it will be equal to length of the cutting edge of the bucket.

The depth of the water supply depends on the climatic conditions. The pipe must be at least 415 mm below the zero temperature penetration into the ground. For northern latitudes this will be from 2 and more meters, for the middle band   1,5-2 meters, for the southern regions - 1-1,5 meta, in these cases, deepen the pipeline to avoid heating the water in a hot period. But, in order to reduce the volume excavation works, the depth of laying of water pipes can be reduced by using heated pipes (air or heating cables). Also slightly reduce the depth, it is possible using heat-insulating materials.

The norms for laying a water pipe with parallel laying or crossing with other communications are also regulated by SNiP. When parallel installation, the horizontal distance from the water pipe must be observed to:

• water supply - 1, 5 m
• sewerage - 0.2 between the outer walls;
• gas pipeline - 1 m;
• power cables - 0, 5m;
• thermal networks - 1, 5 m.

It is possible to lay the sewage and water pipe in a common concrete box.

When crossing with cables and pipelines of various purposes, the water pipe should be laid below not less than 0, 6 meters. If necessary, this distance can be reduced to 0, 25 m. When crossing with sewerage - the water pipe must pass no less than 0, 4 meters above.

For many, the question of how to lay a water pipe in the ground under roads or other cobbled sites is relevant. According to SNIP, it is recommended that such an intersection be made at an angle of 90 degrees (this will minimize the area subjected to heavy loads). In private construction, so-called punctures are usually used - knocking out thick-walled steel pipe   round hole (the diameter should be greater than the diameter of the laid pipe) without disturbing the surface coating. In this case, the distance from the top of the water pipe or its case to the surface should be at least 0.6 meters.

Laying of water pipes from propylene pipes: crossing with sewerage and laying under the road

Today, when deciding for themselves how to build a water pipe in the country, many home masters prefer polymer pipes   from polyethylene and polypropylene. They weigh much less and do not require complicated and cumbersome tools in their work. To install such a pipeline of a small private house within one day is able to even one person.

The construction of the water pipe starts from the point of insertion and installation of the inspection well. According to the current regulations, the well must have a cobbled or concrete bottom, the clearance to the central pipe must be at least 15 cm. Immediately after the tie-in, put the shut-off valve and crane to drain the pipeline if necessary. When laying pipes from the well to the house or other consumers, it is recommended to observe a grade of 0.003 or install drainage cranes at all the lowest points of the system for emptying the pipeline. Wells are provided in all places of inclusion in the scheme stop valves   in the earth.

Since polymers are subject to mechanical damage in order to protect the pipe from possible movements of soil or stones in winter, it is recommended to lay an external water pipe made of plastic on a sand cushion (100-150 mm), followed by sand filling (100-150 mm layer).
