Recently, when installing pipelines, perforated corrugated pipes that have stiffeners and many small holes have been used. These products, when compared with analogues of pipes made of polyethylene, have a huge number of advantages.
Why choose plastic pipes?
The pipe for groundwater drainage can be pottery, asbestos-cement or ceramic. Pottery and ceramic products 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 the minimum term of operation. Among other things, such products contribute to the cost of use. Before installation, cuts were made in the body of asbestos-cement pipes, which was harmful to human health and increased the complexity of the process.
The use of asbestos-cement and ceramic perforated pipes was gradually abandoned due to their heavy weight, which complicated the installation process. Their service life can reach 30 years, and installation work requires special skills. If you do not have certain knowledge, then the work on arranging the drainage system using ceramic and asbestos-cement pipes will last a lot of time. It is almost impossible to independently carry out high-quality drainage with the help of these products in your own area, since manual perforation will allow small parts of soil and sand to pass through, which will lead to fast clogging of the system.
Additional advantages of plastic pipes
Such products are ready to last about 60 years, they have high strength qualities, and also cost quite a bit. In order to save money, you can not resort to outside help. The presence of various types of sizes of polymer products makes it possible to construct drainage systems with high productivity.
Features of plastic drainage pipe
If you need a pipe for drainage, it is best to choose a product that is made of plastic, as it has a number of advantages, among them - long term of use, impressive strength, the absence of corrosion processes, as well as ease of installation. Stiffeners, which are evenly distributed throughout the pipe, contribute to the fact that the products undergo various kinds of impact and load. Such pipes are very resistant to adverse conditions, namely low temperatures and aggressive environments. Among other things, they easily carry transportation and are flexible when laying.
During installation, the use of compensating elements is not required, and the pipes are connected using plastic fittings. The plastic drainage pipe has excellent self-cleaning ability, which is guaranteed by smooth inner walls. According to users, such pipes are characterized by a successful combination of price and quality. If you use polymer pipes for the drainage system , then the water supply pays off in the shortest possible time. This became possible due to the efficient operation of the system, low-cost maintenance and ease of installation.
For reference
The drainage pipe can be laid to a depth of 6 meters. The fact that such pipes effectively collect liquid and quickly pass it, removing water from the site, is facilitated by the presence of a huge number of holes. The latter have a special profile. Some craftsmen make perforated pipes on their own using a conventional drill. But if it is necessary to use a pipe with a filter when laying the system, then it is better to prefer finished products.
Varieties of drainage pipes made of plastic
A plastic drainage pipe may have different materials at its base. In the manufacture of pipes, polyvinyl chloride, propylene, as well as high-pressure polyethylene can be used. Products can have different versions. For deep laying in the soil, a double-walled pipe is suitable, which has improved strength properties. For places where clogging and siltation of small 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.
Installation Recommendations
Work begins with the preparation of a trench along the bottom of which a width equal to the diameter of the pipeline should be selected. To this value, you need to add 40 centimeters. In the cross section, the pit may have a rectangular or trapezoidal shape. At the bottom there should be no solid lumps, a brick fight, sharp objects and stones that could push the bottom wall of the pipe. If you will be laying a pipe for drainage, it is recommended to consider the photo of the product in advance, this will allow you to understand which variety to choose. At the next stage, sand is poured into the trench, and after that - a layer of rubble. Its thickness should not be less than 20 centimeters, and pipes for drainage are laid on top.
Methodology
The upper part of the pipe should be backfilled with a layer 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 a pipe for groundwater drainage is mounted, it is recommended that the master consider the photo. This will eliminate many errors.
You should consider that the sequence of layers is an important factor. Sand refers to water, not crushed stone. The stacked pillow serves as a filter, which allows you to observe the desired bias. Crushed stone and sand, which are filled up from above, act as a filter layer and protect the pipe from mechanical damage. Plastic pipes should be laid to a depth that is below the level of freezing of the soil. In this case, it is necessary to provide a slope of 3 degrees or more.
When a drainage pipe is laid under the road or on the territory of a site of any purpose, it is important to provide for the presence of inspection wells. They should be located in straight sections with a distance of 50 meters from each other. Their presence is important in those places where there will be turns, changes in angles and intersections.
Installation Rules
HDPE drainage pipe with perforation in the filter is necessary to prevent clogging of the system with garbage, leaves and large particles. If you decide to carry out work on laying these elements, it is important to plan the site and find the special information that is most often requested at the local land department. Thus, it will be important to know the seasonal groundwater level, 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 pipe wrapped with geotextile, and the cutting of the parts, if necessary, is carried out with a conventional mounting knife. After laying the pipes, it is important to verify the correctness of their slope, for this the craftsmen use a cord stretched along the pipeline. Inspection wells need to be equipped with covers, which will prevent clogging of the structure. If the pipe for groundwater drainage is laid to an insufficient depth, this can cause a violation of the water balance. It is important to ensure the correct angle of inclination of the elements, if we neglect the above rules, then the functioning of the structures may be impaired, which will lead to problems with the water regime.
For reference
Hoses for drainage are laid in the form of a herringbone, which is considered the most common way. This unit is necessary for conducting a network of pipes into a large collector pipe. Ground water along the collector will go into a roadside ditch or storm sewer. If the place of discharge of liquid is located above the site, then it will be necessary to install a drainage well, water will be removed from it with the help of a pump.
The cost of drainage pipes
After visiting the store, you can pick up a drainage pipe, 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, the diameter of which is 110 millimeters, is 75 rubles. However, even for the same product, sometimes the cost is different.
