plastic blind ditch named Geocomposite dreinage systems (GDS) on international, also known as three-dimensional drainage board, civil engineering materials, such as drainage culverts.
Products has circular and rectangular cross-section, there are several product specifications. According to customer orders with different formulations, high temperature, flame retardant, resistant to strong acid and alkali, high elasticity, high hardness product with different characteristics. With the development of polymer materials, foreign developed plastic blind ditch in the seventies, the product overcomes the shortcomings of the traditional blind ditch, with opening rate, compression performance, large displacement, and good durability. Which was widely welcomed by the engineering sector, and is widely used.
1, plastic blind ditch composition materials is fiber filament about 2mm, pulling each other to form melting point type, three-dimensional mesh body, the principle and the steel truss on the same principle of creation. surface openings was 95-97%, it is 5 times than the one with hole, 3-4 times of the tube,the surface water absorption is very high.
2, because it is three-dimensional structure, the porosity is 80-95%, the same composition and management of space and light, compression performance stronger than the pipe structure of the resin, more than 10 times, so even if the overload is due to pressure, but as three-dimensional structure, so the residual gap is also more than 50%, there is no problem of water barrier, regardless of earth pressure will be crushed.
3, compressive strength large. 250KPa pressure, the compression ratio of less than 10%.
4, there are anti-aging agent, durable in water, soil, etc. were also set to ensure stability for decades.
5, the compressive strength and flexibility, such as for the song bits can bend construction, very light, if the backfill depth of about 10cm, can also be used bulldozers to backfilling.
6, the membrane of plastic blind ditch can be selected according to different soil conditions, and fully meet the needs of the project, and a single membrane to avoid the shortcomings of the old products.
Light weight plastic blind ditch, on-site construction and installation is very convenient, the construction efficiency is greatly accelerated.
7, because of the use of hot melt molding of the way instead of using the binder, it will not peel adhesive such as caused by aging and crumbling.
8, plastic blind ditch itself is modified with the toughness of many of the root surface of plastic wire into the financial statement, there was pressure off, the possibility of damage. 250kpa pressure, the cross-section porosity remains at 60%, even greater pressure exerted, there is always the gap with water, there are still 10-15% of the pore, and the response is good.
III the engineering plastic blind ditch
