The plastic blind drain is composed of a plastic core wrapped with a filter fabric assembly. The plastic core 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.Form a three-dimensional mesh structure. Beneficial for maintaining the drainage cavity, with a lower material density. This product is made by high-pressure extrusion molding, featuring different ribs and grooves on both sides to accommodate drainage, water stoppage, and fixation requirements. It has certain rigidity compared to other soft plastic boards. It is a three-dimensional porous material formed by heating thermoplastic resin to melt it, then extruding fiber strands through nozzles and overlapping them. The points of contact are then fused together. The plastic core is rectangular,Hollow matrix, circular hollow circular, and various other structural forms. Cost-effective with features such as frost and corrosion resistance, resistance to bacterial erosion, and longevity when buried in tunnel linings. This material overcomes the shortcomings of traditional blind gutters, offering high surface porosity, good water collection, high void ratio, excellent drainage, strong compressive strength, good pressure resistance, flexibility, adaptability to soil deformation, durability, lightweight, ease of construction, and significantly reduced labor intensity for workers, along with high construction efficiency.Therefore, widely welcomed by engineering departments and extensively applied, the plastic underdrain is composed of fibers in the range of about 2mm, fused and shaped into a three-dimensional mesh structure at their junction points. Its principle is similar to the truss principle of steel structural constructions. The surface has openings covering 95-97%, which is more than five times that of a perforated pipe and 3-4 times that of a resin mesh pipe, with an extremely high surface water absorption rate. Internationally, it is known as Geocomposite Drainage Systems (GDS), also referred to as three-dimensional drainage boards, and materials for civil engineering drainage channels, etc.
