Drainage pipe for removing groundwater: product classification

This article discusses the drainage pipes to drain groundwater: shows the complete classification of products for drainage, their advantages, characteristics and basic parameters. With this information, you will learn how to select suitable types of pipes for certain types of efferent systems in accordance with their requirements, characteristics of the soil and so on.

Drainage pipe for removing groundwater: administering to the subject

Drainage pipe acts as a basic building element on which water taking system is formed, intended to drain portions. This element is responsible for the collection and diversion of underground, melted snow and rainwater from the territory of a pre-filtering.

Note! Large amount of snowmelt and rainwater is able to provoke a rise in the groundwater level. The emergence of such a situation is extremely undesirable, since as a result of increasing destructive the impact on the foundation of the building, as well as all elements of landscape design, located on the site.

Installation of drainage pipes of large diameter makes it possible to deal with problems such as:

• Increased soil moisture;
• mold formation;
• flooding of land, the foundation of residential buildings and buildings of economic purpose, as well as cellars;
• formation of frost;
• appearance of puddles on paved surfaces;
• the formation of ice on the sidewalks;
• root rot garden flowers, vegetable crops and other vegetation due to excess moisture in the garden and suburban areas.

Especially drainage pipes with partially perforated, full or no

If we talk about the general classification of products for drainage systems, the range represented by the following kinds of pipes (by type of material):

• asbestos cement;
• ceramic;
• plastic drainage pipes with and without perforation, as well as its partial presence.

However, the majority of construction companies have already refused to use pipes made of ceramic or of asbestos because of the many disadvantages of them:

1. Heavy, requiring significant costs for transportation and installation, after the installation of such a dimensional products can not do without the use of specialized construction equipment.
2. The slow process of installation of drainage systems, which can be carried out only by the hands of professionals.
3. Low performance. Available usually represented drainage pipe without perforation holes so performed manually. Because of this, during the operation of the pipeline is clogged quickly, requiring frequent cleaning, and in some cases, complete replacement of the elements.
4. Building systems based on them is much more expensive than in the case of the use of plastic components.

Note! The table shows the average price of drainage pipes 200 mm from different materials. There are other embodiments of the diameter, however, in products made of ceramics, plastic, asbestos cement and the standard dimensional parameters do not match. Therefore, for comparisons taken diameter drainage pipe 200 mm, which is present in the range of all these products.

Advantages of plastic drainage pipes: HDPE and PVC

Plastic products (PVC) in many respects superior to the characteristics of asbestos cement and ceramic products for drainage.

A list of their virtues:

1. Long service life.
2. High strength.
3. Complete invulnerability against corrosion.
4. Light weight to facilitate not only the process of transportation, but also the installation procedure, as well as accelerating the timing of its implementation.
5. Due to the presence of a range of large number of connecting elements (fittings, tees etc..) Mounting system is obtained a rapid, reliable, comfortable.
6. The smooth surface prevents build-up of dirt, delaying process clogging.
7. Use of a geotextile drainage pipes of 200 mm or more system eliminates the possibility of sedimentation.
8. All installation work can be carried out with their own hands, because it does not require special education, does not need special equipment and special construction machinery.

On the example of drainage corrugated PVC pipes of 200 mm in diameter, you can make sure that the cost of these products can also be attributed to the significant benefits of plastic products.

Range of plastic pipes comprises several categories of products:

• PVC;
• polyethylene;
• Polypropylene.

The most popular on the market are considered to be a pipe for drainage systems from PVC.

Features of PVC drainage pipe: the classification of products according to various criteria

Products made of PVC and other polymer materials can be divided into the following categories:

• dual layer and single layer;
• flexible tubes (produced in coils, whose length is 40-50 m);
• tough products for draining systems (their length is fixed, in the range represented by pipe lengths from 6 to 12 m);

• products with different strength class (character marking SN: 2,4,6,8,16);
• wrapping the pipes with a filter or without it.

Note! The table contains the average price of drainage pipe in geotextile filter 200 mm and perforated corrugated surface. Depending on the manufacturer, this figure may vary.

Rates drainage pipe 200 mm (in the geotextile and without it):

Monolayer (SN4)	40	9000

Products presented for sale, can have a diameter from 50 to 200 mm. There are also more massive options relating to drainage pipes of large diameter.

Characteristics of perforated drainage pipes

Flexible monolayer product with perforation can be used at depths of no more than 3 m. Class pipes also indirectly indicates the recommended depth Bookmarks. In the case of pipes SN2 depth should not exceed 2 m, SN4 - not more than 3 m.

Double tubes have a smooth inner surface. In this case the outer side is corrugated. Generally, such articles have an annular SN6 strength. When constructing drainage systems are no more than a length of 4 m. As the filter may be attached thereto coir or geotextile. On sale there are products without filter.

Flexible corrugated perforated drainage pipes are marked SN8 class. Supplied complete with filter material and without it. Designed for deep bookmarks - up to 10 m Two-layer product of the same class let you bury the system is not more than 8 m They are made without a filter...

The average price of drainage pipes 160 mm and 110 mm with perforations and corrugating (3m):

Product Features Perfocor: products for drainage systems

Pipes successfully used Perfocor dewatering. Perforations on their surface allow water to penetrate the articles. After that, she is transported further in the sewer system or displayed in an artificial or natural pond.

Scope extended to the construction of:

• various buildings;
• roads;
• stadiums;
• airports;
• as well as the reclamation of agricultural land.

Note! The openings on this species pipes have optimum sizes that are large enough to pass into the water system, but small enough to prevent penetration of earth, debris, sludge and other particles capable of withdraw drains out of service.

Compound corrugated perforated drainage pipes Perfocor carried out in several ways. For this combination may be used and the coupling sealing ring or docking welding.

Due to the fact that the rubber pad is placed inside the corrugations during the connection elements of the system, during mounting, this item can not be displaced. The gasket of rubber, intended for connection, has the same profile as that of the pipe. Therefore eliminates the possibility of leakage of the pipeline, as well as getting into the groundwater.

Specificity corrugated perforated drainage pipe with geotextile

As an effective complement to the pipeline, which enhances the timing of its operational life, using different types of filters. Such materials include geotextile fabric, and coconut fiber.

Corrugated perforated drainage pipes with geotextile 160 mm and more are products with a large number of openings arranged rationally, as well as stiffeners. These small holes are placed in the cavity, which is formed between the waves of the corrugations.

Stiffeners provide uniform distribution of pressure exerted on the soil pipe. Due to the fact that the load is distributed over the entire length of the pipe, the drainage system can not only withstand the soil pressure, but also all the additional stresses arising.

These kinds of pipes are used for laying the pipeline at a depth of 0,7-6 m. Due to the large number of holes which occur in 1 m. P. a special profile products made rapid collection of water by passing it through the system and the removal beyond the suburban area.

Note! Plastic products have a light enough weight, so they can be considered as the best choice of material for the creation of drainage systems with their own hands. Bay length of 40 m and a diameter of 160 mm weighs about 25 kg.

The diameters of the culverts and particularly their application elements

If you take for creating a drainage system on the site with his own hands, should take into account the following recommendations:

1. The effectiveness of the system depends on how true is your choice with respect to the pipe diameter.
2. The perforated article having a diameter of 110 mm capable to perform the water drainage portion in a radius of 5 m. This information should be considered in the design layout drainage.
3. The pipes must be laid with a slope in the direction where the installation of a well or septic tank would be produced.
4. The process of connecting all the pipe elements to be technically correct.

63 mm diameter tubes are used along with the articles 110 mm. In each such element has a network of small holes.

Experts recommend purchase drainage pipe 63 in geotextile filter for use in areas which are arranged in depressions or in areas where there is a high ground water level. This material can be used for arrangement of drainage in the construction of a cellar, an underground garage, as well as the houses of the modern type, with the ground floor.

Note! Choosing the diameter of the pipes is directly dependent on the depth to which the system will move deep drainage. For example, products with a diameter of 63 cm may effectively perform their work to a depth of 8 m. The depth exceeding this rate, they are not suitable.

Selection for draining pipe system in the area of ​​soil type

Base part of any structure may be blurred even groundwater at a depth of 1.5-2 m. Groundwater include in its composition components can destroy the base. Waterproofing is powerless in such cases, so we have to resort to more drastic measures - construction of drainage system. It should take into account the type of soil and the degree of hydration.

The increased water content in the soil can lead to freezing and rotting plants, the appearance of fungus on them and on fruit trees and swamping territory. In this case it is recommended to use corrugated pipes made of polyethylene. With their help you will provide fiscal and fast drainage system, which will remove the groundwater pressure and significantly reduce their level.

The types of soils and the best materials:

type of soil	Recommended material for drainage
crushed stone	Products with perforation without filter material
Sandy	pipe with a filter of geotextile fabric of rubble mound +
Clayey	pipe with a filter or without a rubble mound of + 0.2 m thick
Loam (combined)	products with a filter of geotextile fabric

Characteristics of plastic drainage pipe 300 mm

Plastic pipes for drainage systems have established themselves as a strong, reliable products. They are economical and effective. The use of polymer products can significantly reduce the cost of electricity and money for works on drainage area. Such a system is able to serve for 40-50 years.

Technology drainage arrangement involves the use of filter materials typically geotextile.

Note! Pipes with a diameter from 63 mm to 250 mm are sold already wrapped in geotextile. Products with a larger diameter are used for the construction of manufactured objects. They also need geotextile wrap, which in this case is carried out manually.

The average price of drainage pipe 300 mm of the polymers is 200-300 rub. / M. P. If the product does not have the bells, their cost is reduced by about 50-100 rubles. In the draining systems use similar embodiments pipes of cast iron. Their value is in the range of 350-450 rubles. / M. P.

Regardless of the size of the product system is always set at an angle and in every case it is necessary to adhere to certain parameters. Installation pipes with diameter of 300 mm is carried out with a slope of not less than 3 mm. As this kind of products can match the rigidity SN6 classes and SN8, laying the pipeline can be carried out to a depth of 2 m.

Characteristic drainage pipes of large diameters for the ditch

Selecting pipe diameter is also dependent on the inflow of groundwater. In other words, the selection of products to the drainage system is based on the indices reflecting the amount of water which runs for 1 second.

There are important other factors:

• the level of groundwater;
• amount of excess moisture;
• character of the landscape.

Corrugated PVC drainage pipe diameter of 500 mm, 400 mm and 630 mm are two-ply products. They have a double-wall corrugated layer on the outside and on the inside surface thereof is smooth.

Due to the presence of corrugated pipe walls exhibit a high resistance to the occurrence of any deformation under load changes. The range of modern construction market, you can find the products corresponding to the following classes of ring stiffness:

• SN4;
• SN8;
• SN16.

Such diversity makes it possible to lay the pipeline at different depths. Plastic pipes of large diameters have a wide range of operating temperatures. Extreme points correspond to -40 ° C and + 60 ° C.

The average price of drainage pipes 400 mm, 500 mm and 630 mm (Perfocor):

type of product	Diameter, mm	Length	Material	Price, rub. / Pcs.
The two-layer SN8	400	6	HDPE	2600
The two-layer SN16	400	6	HDPE	3590
The two-layer SN8	500	6	HDPE	3800
The two-layer SN16	500	6	HDPE	5350
The two-layer SN8	630	6	HDPE	5250
The two-layer SN16	630	6	HDPE	7230

Useful advice!Construction line for removing excess moisture from the area - is not the only area of ​​application of such products. Use pipes with a large diameter as drainage wells for drainage control system status, as well as its cleaning.

Further guidance on the use of pipes

Work on the construction of a drainage system on the site most often held in conjunction with its development. To drain functioning it is necessary to arrange for him the maximum flow of water. Indicator that determines moisture access to the pipeline, called the soil permeability. To increase it applies dusting special filtration materials.

Such materials include:

• gravel;
• gravel;
• pebbles.

Due to increased volume of the filter portion to the liquid entering the system. To drainage is not filled with silt and mud, the rate of flow of water through the pipes should be at least 0.2 m / sec.

Common errors when laying drainage:

• use of pipes which are not designed for installation in a particular soil type (e.g., the use of the pipe without the geotextile filter loam soil);
• no filter dusting;
• lack of necessary biases;
• backfilling not filter primer;
• untimely removal of accumulated liquid from the collection well.

Efficient operation of the drainage system depends not only on the compliance mount technology, but also the maintenance of the pipeline during subsequent operation.

Maintenance of drainage system requires regular check for blockages and malfunctions, eliminating those when they are detected. In addition, regularly need to monitor the status of the groundwater level in the territory of a country site in order to know how to cope effectively with the drainage of excess moisture withdrawal. Also does not hurt to check the quality of groundwater.

Thanks to the timely the scheduled repair and maintenance work, as well as the elimination of fault, you can not only increase the service life of pipelines, but also eliminate the possibility of of accidents.
