The sub-ground system for the dispensation of structural elements (cans, tubes, wells, traps, fittings, etc.) on the canal networks is called drainage. Its main purpose is to collect and remove from the land of groundwater or rainwater.
One- and two-stop drainage pipes as the necessary component of the system shall be collected according to the soil type, have different diameters, be manufactured with perforation in all lengths and filters and placed on the perimeter of the site.
Excessive vagina on hand or gardens may cause harm not only to crops but also to build, because it is desirable to combine soil drains and foundations.
Types and technologies of drainage device
The drainage system on the site can be done in two ways: by deep or surface drainage of the soil, which differs by technology of devices and functionalities.
Deep drainage is necessary for the wet or near the watermelon and the lowland. It is mainly based on sand and gravia and provides for underground channels for the removal of deep-rooted groundwaters most dangerous to the building ' s foundation.
Some tranches are not enough, so the system uses drains, perforated tubes and rolling materials that need to fall asleep, first cheek and sand, and then land. Gathering water a drain. Not long ago, asbestos cement or ceramic tubes were used to drain, but they required frequent washing because of the debris.
Today, polymer tubes have emerged in a diameter of between 50 and 200 mm for hydromelioration, facilitating drainage, allowing for a pipeline to remove excess water from the border of the site.
Surface drainage serves as the collection and removal of veal and rainwater sections and roofs, protects the integrity of soil layers, cloams, roads and water bodies. System channels are located on the ground.
This kind of drain can be accurate and linear. The precise surface drain collects water in the areas of its accumulation, which are covered by the filter, the decorative metal bars to prevent any debris from entering the pipes. Points shall be placed on one main tube, pouring water into the nearest water or ovarian, or connected to the sewerage or drainage well.
