WOVEN POLYPROPYLENE GEOTEXTILE FOR DRAINAGE SYSTEMS

摘要

The utility model relates to the field of construction and can be used for the construction of drainage systems of various types, the device of protective-filtering and reinforcing layers in embankments on soft soils and in difficult soil-geological conditions and the bases of road pavements, anti-erosion protection and strengthening of slopes, bridge cones and overpasses, dams and banks of water bodies, manufacturing geotubes as containers for dewatering and drying various types of water-insoluble solids and industrial waste, manufacturing geotubes for the construction of breakwaters, dams, breakwaters and artificial islands in hydraulic engineering, as protective shells for ground piles ...;Filter woven geotextile, characterized by the fact that it is made in the form of a cloth with a plain and twill weave of polypropylene threads with a melt flow rate of 3-5 g / 10 min with the addition of an antifibrillation additive of calcium carbonate and a UV stabilizer, while threads with a linear with a density of 700-6000 denier and a width of 4-12 mm with a high degree of fibrillation, and flat threads with a linear density of 1000-4000 denier and a width of 1-4 mm are used on the basis, while the filtration coefficient of geotextiles is 40 m / day at a pressure of 100- 200 kPa.;The technical result achieved by the claimed utility model is to increase the culvert capacity of the drainage system by 1.5-2.5 times, on which it is installed. 3 C.p. f-ly.
