Pipe for groundwater drainage (photo)
Recently, with the arrangement of pipelinesPerforated corrugated pipes are used that have stiffeners and many small holes. These products, if compared with analogues of polyethylene pipes, have a huge number of advantages.
Why choose plastic pipes
A pipe for drainage of groundwater can bepottery, asbestos-cement or ceramic. Pottery and ceramics were used in the process of agricultural development of territories. However, these pipes have many disadvantages, they consist in the need for frequent flushing, as well as in a minimum period of operation. Among other things, such products contribute to the costs of use. Before the installation in the body of asbestos-cement pipes, cuts were made, which harmed human health and increased the laboriousness of the process.
From the use of asbestos-cement and ceramicPerforated pipes were gradually abandoned due to their large weight, which complicated the installation process. The period of their operation can reach 30 years, and installation works require the availability of special skills. If you do not have certain knowledge, then the work on the arrangement of the drainage system with the help of ceramic and asbestos-cement pipes will last a long time. It is almost impossible to perform quality drainage with these products on site on your own, as manual perforation will let in small parts of the soil and sand, which will lead to a rapid clogging of the system.
Additional advantages of plastic pipes
Such products are ready to serve about 60 years, theyhave high strength properties, and also stand quite a bit. In order to save money, you can not resort to outside help. The presence of various types of polymer products allows the construction of drainage systems with high productivity.
Features of drainage pipe made of plastic
If you need a drainage pipe, it's betterjust choose a product that is made of plastic, as it has a number of advantages, among them - a long period of use, impressive strength, no corrosion processes, and ease of installation. Stiffeners, which are evenly distributed throughout the pipe, contribute to the fact that the products undergo various kinds of impacts and loads. Such pipes are very resistant to unfavorable conditions, namely low temperatures and aggressive environments. Among other things, they easily tolerate transportation and exhibit flexibility when laying.
When installing, you do not need to usecompensating elements, and the connection of pipes is carried out with the help of plastic fittings. The drainage pipe made of plastic is excellent in self-cleaning ability, which is guaranteed by smooth inner walls. According to users, for such pipes is characterized by a successful combination of price and quality. If you use polymer pipes for the drainage system, then the water pipe pays off in the shortest possible time. This has become possible to achieve due to the efficient operation of the system, inexpensive maintenance and ease of installation.
The drainage pipe can be laid to the depthup to 6 meters. The fact that such pipes effectively collect liquid and quickly pass it, removing water from the site, contributes to the presence of a huge number of holes. The latter have a special profile. Some masters make perforated pipes themselves, using a conventional drill. But if you need to use a pipe with a filter when laying the system, it is better to prefer finished products.
Varieties of drainage pipes made of plastic
A pipe for drainage from plastic can have differentmaterials at the base. In the manufacture of the pipe, polyvinyl chloride, propylene, and also high-pressure polyethylene can be used. Products can have different versions. For deep laying in the ground, a double-walled pipe is suitable, which has enhanced strength properties. For places where clogging and siltation with fine particles is possible, it is recommended to use a drainage pipe with a filter. A pipe for drainage of groundwater of large diameter is used in cases where it is necessary to divert a large volume of liquid.
Begin work with the preparation of a trench, along the bottomwhich should be chosen the width equal to the diameter of the pipeline. To this value, you need to add 40 centimeters. In the cross section, the pit may have a rectangular or trapezoidal outline. At the bottom there should be no solid lumps, bricks, sharp objects and stones that could push the bottom of the pipe. If you fit a drainage pipe, it is recommended to review the product photo in advance, this will allow you to understand what kind of variety to choose. At the next stage, sand is poured into the trench, and then - a layer of rubble. Its thickness should not be less than 20 centimeters, and pipes for drainage are laid from above.
Methods of work
The upper part of the pipe should be covered with a filling oflayer of crushed stone, the height of which should be 20 centimeters or more. Next is a layer of sand, and the outer part of the soil is laid with turf. When installing a pipe for groundwater drainage, the photo is recommended for the master to be considered. This will eliminate many errors.
You must take into account that the sequence of layersis an important factor. Sand is drawn to the water, and not crushed stone. The padded pillow serves as a filter, which allows you to observe the desired slope. Crushed stone and sand, which are filled from above, serve as a filter layer and protect the pipe from mechanical damage. Plastic pipes should be laid to a depth that is below the freezing level of the soil. In this case, it is necessary to ensure a gradient equal to 3 degrees or more.
When the pipe is laid for drainage under the roador on the territory of the site of any destination, it is important to provide for the availability of inspection wells. They should be located on straight sections with a distance of 50 meters from each other. Their presence is important in those places where there will be corners, changes in angles and intersections.
Pipe for drainage of HDPE with perforation in the filterIt is necessary to prevent clogging of the system with debris, leaves and large particles. If you decide to carry out the work on laying these elements, it is important to plan the site and find the special information that is most often requested from the local land department. Thus, it will be important to know the seasonal level of groundwater, the amount of water that falls in the form of precipitation, soil characteristics and soil structure.
On the prepared pillow you need to lay the wrappedgeotextile pipe, and the cutting of parts, if necessary, is carried out with the usual mounting knife. After laying pipes it is important to check the correctness of their slope, for this master use a cord stretched along the pipeline. Observation wells must be equipped with covers, which will exclude littering of the structure. If the pipe for groundwater drainage is laid to a shallow depth, this could cause a water balance disturbance. It is important to ensure the correct slope of the elements, if you neglect the above rules, then the functioning of the structures may be violated, which will lead to problems with the water regime.
Hoses for drainage are laid in the form of a Christmas tree,which is considered the most common way. This node is necessary for conducting a network of pipes in a large collecting pipe. Groundwater through the collector will go into the roadside ditch or storm sewer. If the place of discharge of liquid is located above the site, it will be necessary to install a drainage well, water will be removed from it by means of the pump.
Cost of drainage pipes
When you visit the store, you can pick up the drainagepipe, which can cost 70 rubles. minimum. Depending on the diameter, type and type, as well as the number of products purchased, the price can vary up to 4000 rubles. The cost of a double-walled pipe, whose diameter is 110 millimeters, is 75 rubles. However, even for the same product sometimes the cost is different.
