Huai'an Drainage Plastic Blind Trench Manufacturer's Quotation

The plastic blind trench is composed of a plastic core tube wrapped with a filter fabric assembly. The plastic core tube is mainly made of thermoplastic synthetic resin, which is modified and then extruded into fine plastic filaments in a molten state through a nozzle. These filaments are then fused at junction points by a molding device.Forms a three-dimensional mesh structure. The plastic core has various structures including rectangular, hollow matrix, circular hollow circle, etc. This material overcomes the shortcomings of traditional blind channels, featuring high surface aperture rate, good water collection, large porosity, excellent drainage, strong compressive resistance, good pressure resistance, good flexibility, adapts to soil deformation, excellent durability, light weight, easy construction, significantly reduced labor intensity for workers, and high construction efficiency, thus gaining widespread popularity among engineering departments and extensive application.This product is made by high-pressure extrusion molding, featuring different ribs and grooves on both sides to cater to drainage, water-stop, and fixation requirements. It has greater rigidity compared to other soft plastic sheet materials, which is beneficial for maintaining the drainage cavity. The material has a lower density, resulting in a reduced cost. It boasts characteristics such as cold resistance, corrosion resistance, resistance to bacterial erosion, and resistance to aging when buried in tunnel linings, ensuring a long service life. Internationally, plastic underdrains are known as Geocomposite Drainage Systems (GDS).Also known as three-dimensional drainage boards, civil engineering drainage channel materials, etc. It is a three-dimensional porous material formed by overlapping fiber filaments extruded from thermoplastic synthetic resin heated and melted through a nozzle, and then fusing their junction points. Available in circular and rectangular cross-sections, with various product specifications. Different products with characteristics such as high heat resistance, flame retardancy, resistance to strong acids and alkalis, high elasticity, and high hardness can be produced according to customer orders.
