 Description: A Product: plastic blind ditch, also known as underground drain, culverts, etc., the main effect is a row of soil water seepage. To reduce ground water pressure, remove excess moisture, protect soil and penetrate the building will not produce distortion and damage. Widely used in civil engineering, transportation, water conservancy, civil, miners, underground construction projects such as environmental protection, set of drainage works. With the development of polymer materials, developed in the seventies foreign plastic blind ditch, the product overcomes the shortcomings of the traditional blind ditch, with the opening rate, compression performance, large displacement, durability and good. Which was widely welcomed by the engineering sector, and has been widely used. China from the eighties started to develop a new generation of plastic blind ditch material, and developed in the early nineties for practical engineering application products. Second, characteristics: plastic blind ditch itself is modified with the toughness of many of the root surface into a plastic wire financial results, and there is pressure off, destroying possible. 250kpa pressure, the cross-section porosity remains at 60%, and even to exert greater pressure, there is always through the water gap, there are still 10-15% porosity, Fushun Drainage Board - Fushun Drainage Board - Fushun Fushun Drainage Board Drainage Board! - @ Fushun Fushun Drainage Board Drainage Board - Fushun Drainage Board - @ Fushun Fushun Drainage Board Drainage Board - Fushun Drainage Board
