　　Shandong cement mobile house factoryTo provide you with how to do waterproof knowledge 'plastic blind ditch, also known as dark ditch, culvert, etc., the main role is to collect drainage soil seepage。It is used to reduce groundwater pressure, remove excess water, and protect soil and buildings from damage due to infiltration deformation。Widely used in civil engineering, transportation, water conservancy, civil construction miners, environmental protection and other construction projects of underground drainage projects。With the development of polymer materials, foreign countries have developed plastic blind ditch in 70 years, the product has overcome the shortcomings of traditional blind ditch, with high opening rate, strong compression performance, large displacement, good durability and other advantages。Therefore, it is generally welcomed by the engineering field and has been widely used。China began to develop a new generation of plastic blind ditch materials from the 1980s, and developed products for practical engineering applications in the early 1990s。

特点：

　　The plastic blind groove itself is made of many modified plastic wires with toughness, and there is no possibility of being crushed or destroyed。Under 250kpa pressure, the porosity of the section remains above 60%, and even if a larger pressure is applied, there is always a water gap, there are still 10-15% pores, and the recovery is good。

　　The three-dimensional mesh combination of the filter membrane made of corrosion-resistant fiber and modified polyethylene has the advantages of non-degradation in soil and water, and the anti-aging formula can ensure that the persistent material does not change。

　　The filter membrane of the plastic blind ditch can be selected according to different soil conditions, fully meeting the needs of the project, and avoiding the single shortcomings of the old product filter membrane
