At the stage of planning a house or a summer residence, land owners are wondering how to prevent flooding of the territory with precipitation or groundwater. In autumn, during rains or in spring, during the period of snow melting, puddles can form on the plot of land, which not only interfere with movement, but also spoil the materials at the base of the foundation and walls, and also negatively affect cultivated plants.
From constant stagnation, the soil becomes waterlogged, oxygen does not enter inside. In order for the land plot not to turn into a swamp, it is necessary to drain it, which can be helped by drainage pipes, the types of which will be discussed below.
Classification of drainage pipes
In modern construction, three types of drainage products are used, among them it should be noted:
- polymer perforated;
- ceramic;
- asbestos-cement.
The last two are rarely used becausehave some disadvantages, namely:
- impressive weight;
- difficult installation process;
- low performance;
- expensive styling;
- short life span.
High weight can complicate installation, as well as transportation and unloading / loading of materials. Installation work using ceramic and asbestos-cement pipes is accompanied by certain difficulties. Masters must have special skills, in addition, a lot of time is spent on work. The system, arranged with the help of such products, clogs up quite quickly. The service life is short and reaches 30 years.
Why choose a plastic variety of drainage pipes
Drainage polyethylene pipes (GOST 32413-2013) have many advantages, such as:
- long service life;
- high strength;
- non-corrosive;
- light weight;
- self-cleaning ability;
- low cost;
- variety of standard sizes.
Such pipes are ready to serve for about 60 years. They have two walls, as well as additional stiffeners, which contribute to the distribution of loads. The material in their base does not corrode and is resistant to aggressive environments. It is easy to transport due to its low weight, as well as to carry out installation.
Plastic pipes are very smooth inside, so they rarely clog. You can buy them at a low cost, and onyou can pay for installation work and not spend money at all. This makes plastic drain pipes even more attractive.
Varieties of plastic pipes for drainage
Before you start choosing the diameter of the drainage pipe, you need to understand the main varieties. If we are talking about plastic products, then they can be made from:
- polypropylene;
- polyethylene;
- PVC.
The most common last type of pipe that happens:
- flexible single layer or double layer;
- naked or with a filter shell.
Flexible are produced in reels, and their length can reach 50 m. Rigid PVC pipes have a length ranging from 6 to 12 m. As for the presence of a filter shell, it can be made of coconut fiber or geofabric. Polypropylene drainage pipes, the diameter of which will be mentioned in the article, are not much inferior to those described above in popularity. They can be corrugated or smooth, and their minimum diameter is 50 mm. Such products should be selected taking into account the stiffness class.
Drainage diameter
Before starting work on laying the drainage system of the site, it is important to choose the diameter of the drainage pipe. This setting will affect system performance. If it is necessary to drain water in large volumes, it is required to use pipes of an impressive diameter, which reaches 300 or 400 mm. But for domestic needs, drainage pipes of 200 mm are suitable.
The most popular are products with a diameter of 110 mm. By purchasing pipes of small size, you will receive products wound on coils. But if we are talking about an impressive value, then pipes with such parameters are sold in segments. In order to determine the diameter, it is necessary to take into account the features of the terrain, among them:
- filtration factor;
- ground type;
- moisture level;
- inflow volume;
- freezing.
For example, if you need to drain an area up to 400 m22, you need to use a pipe with a diameter of 110 mm. In this case, the groundwater coverage radius will be equal to 5 m. In addition, a geotextile fabric can be installed, which will allow filtering from debris.
When choosing a drainage pipe with a diameter of 400 mm, you will need to prepare a trench for it, the width of which is 40 cm larger compared to the mentioned parameter. This indicates that the hole should be 800mm wide.
200 mm pipes are great for large areas. At the same time, they must be deepened by 8 m, taking into account the pressure of the soil. Diameters within 315 and 425 mm are mine and are necessary for the construction of wells. They withstand maximum loads, have a long service life and have high anti-corrosion properties.
Assignment of drainage pipes
Drainage pipes with a diameter of 300 mm can be single-layer. They are designed for laying to a depth of 2 m. But if we are talking abouttwo-layer products, they are able to withstand loads at a depth of up to 10 m. A 300 mm pipe is used to drain excess water in industrial and civil construction during the construction and arrangement of parking lots, sports fields, airports and garden plots.
On sale you can find 200 mm drainage pipes. They are mainly used in the construction of airfields and sports facilities, as well as country, cottage and road improvement. Such pipes are perfect for landscape design of the territory.
Assignment of large diameter pipes
Drainage pipes of large diameter, as well as with other parameters, are designed to protect the site and the house from mold and freezing, high humidity, as well as flooding and rotting of plants. Thanks to such systems, puddles and ice will not form on asph alt and pedestrian paths.
Pipes can be plastic, pottery or asbestos cement. Drainage pipes of large diameter are used when it is necessary to divert an impressive amount of groundwater. Pipes can be placed at the level of the foundation. This is due to the fact that it is here that a largeamount of water, it can have a negative impact on any structure.
Additionally about the diameter of pipes "Perfokor" and "Logistics"
Special attention deserves the material that forms the basis of the drainage pipes "Perfocor". For them, high-modulus polyethylene is used, to which mineral substances are added. Thanks to this manufacturing technology, these pipes acquire increased rigidity characteristics.
The diameter of the drainage pipe in this case most often has the following values: 110, 160 and 200 mm. If necessary, you can purchase products with a more impressive diameter - 400 mm. The pipe can also have a rectangular flat shape, it is supplied in coils. In this case, we are talking about products "Logistics".
They are made of low-density polyethylene and have reinforcing internal elements, which are possible only in rectangular pipes. The main advantage of such pipes is their compactness. Such drainage pipes for sewerage, having a diameter within 110 mm, take up only 2.5 times more space during transportation and storage compared to flat pipes of the same size.
Features of drainage pipes
When choosing drainage pipes, you will notice that they have some features, expressed in partial or complete perforation. This affects many characteristics of the system. Full perforation provides holes that are 60° apart around the circumference. This points tothe fact that the cross section has 6 holes with a diameter of 1.3 mm. Three holes will be at the top of the pipe when partially perforated.
To protect the holes from clogging, they are made between corrugations connected by stiffeners. The latter allow you to distribute the load on the product as evenly as possible, which affects its durability. The conditions for the use of drains provide for the use of certain models of pipes, each of them is designed for the high-quality performance of its tasks. For this reason, it is necessary to decide what drainage work is carried out on the site, as well as which pipes to choose for this.
In closing
In addition to the above, we can add that a two-layer pipe with excellent strength characteristics is ideal for deep laying. Structures with a filter layer are designed for use in places where there is a possibility of clogging and silting of the system with sand and small soil particles. Such products allow you to save money, because you don’t have to purchase additional geotextiles or coconut sheets.
