Double-wall drainage pipe: series 14

Drain double wall pipe with gefilta, which is used to divert water away from building foundations, roads, outdoor sports activities.
TASKS
- Protection of deep and light foundations of buildings and structures;
- Protection against landslides foundations of roads and road structures (foundations of bridge and tunnel crossings);
In the agricultural and horticultural sector for drainage of soils with shallow groundwater level (protection of root systems of plants);
- Drainage of seepage into the ground;
In the complex of sports surfaces in open areas (without canopy), stadiums, etc.

The drainage surface is a classic option for drainage works in areas with a shallow groundwater table, resulting in waterlogging of the site. Drainage is divided into two types - indoor and outdoor. The latter requires the presence of open grooves, located on the border of the plot, which merges collected from the site excessive moisture.
Subsurface drainage device of buried channels (drain). Drainage is a necessary condition for the maintenance of the grounds and paths in a dry condition, prevent rotting of the root system planted on a plot of plants, protection of foundations and basements of the excess moisture. For drainage, a draft that defines the location of drains, depth, structure, slope, slope channels, selection of components and materials, the possibility of coupling of the individual elements of the drainage system.
Open drainage system consists of a collective of drains, drainage drains, main canal, wells and water intakes. If the drainage system should operate in the cold period of the year, the drains must be installed at the depth of soil freezing.
A pair of separate elements of the drainage system is made using a special tees and couplings suitable diameter. While the presence of the rubber seal is not required, which greatly accelerates the process of installation of the drainage system.
The distance between the pipes of the drainage system depends on the specific requirements to drying of the soil, rainfall intensity and permeability of the soil. It usually varies between 5 and 12 meters.
The slope of the side branches shall be not less than 0,004, trunk - less than 0,003. If the soil structure, it is best to create a slope of 0.005. The special importance of these requirements to acquire in the case of silty soils.
Lateral pipes to collect water are usually laid at a depth of one meter and more. Mainline pipe shall lie somewhat lower (6-7cm). Actually pipe (experts call it Drenai) is in the walls of a network of holes with a diameter of approximately 1.5-5 mm, They are all or nearly the entire circumference of the pipe at a certain distance from each other. Up through the capillaries of the soil moisture in a natural way is sucked into the tube. In and about the building, and under it is formed of depression funnel - space with dry soil. In each case the depth and the size of the approximation of the drainage to the building are determined separately. The drainage area at 1 meter drain pipes from 10 to 20 m2.
To prevent clogging, clogging of the holes with sand and soil some brands drainage pipes provide wrappers of filter material - GEFILTE, such pipes are used in sand, loamy sand, peat and clay soils.
Special ribs allow you to distribute the load from overlapping primer evenly over the entire length of the drain, making it remain durable and reliable. Depth of laying of polyethylene pipes and their diameters are determined by a specialist, depending on the type, degree of hydration and other local features (in order to ensure the normal operation of the drainage pipe down on nepronitsaemoe a depth of at least 80 cm; maximum laying depth - 6 m).
