Covered with cloth :90-400g / m2 non-woven geotextiles, filter cloth technical indicators are in line with national standards. Quality Characteristics Plastic blind ditch the chaos by the modified polypropylene filament fusing with each other take the junction after the formation of the frame structure, the outer layer of geotextile fabric wrap. Plasterers working through the outer casing into the water into the plastic filter cloth blind ditch, emissions out. High compressive strength, good pressure Traditional low-compressive strength of materials are often blind ditch, at a higher pressure easily damaged, leading to drainage failure. The high compressive strength of wood plastic blind ditch, and the response is good, generally 250KPa (25T/m2) remained under pressure section porosity above 60%, and the pressure drops, the restore status quo ante. Since there is no overloading or failure of other causes drainage problems. Flexible, strong ability to adapt to soil deformation Wood plastic blind ditch pressure not only good, but also has good flexibility, so they can adapt to the deformation of the surrounding soil, not because it is overloaded, severe deformation of the foundation, uneven settlement and other reasons to ditch off the blind, to avoid the blind set due to various reasons ditch drainage failure accidents. Durability Plastic blind ditch material, the use of anti-aging formula, its stable performance, with anti-UV, high temperature, corrosion resistance and other characteristics, so blind ditch plastic material in water, soil for decades can be set to maintain structural stability and maintain the performance of drainage . Surface porosity Surface channel opening rate refers to the blind hole surface area and surface area ratio, generally expressed by%. Absorbent materials to reflect the ability of blind ditch an important performance. In general, the larger the surface porosity, water absorption less likely clogging the better. Opening rate of the surface is too small it is easy to clogging, poor permeability. Drainage effects are worse. Under normal circumstances the surface should be ≥ 85% open porosity
