The plastic blind channel is composed of a plastic core wrapped with a filter fabric assembly. The plastic core is primarily 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 together at junction points by a molding device, forming a three-dimensional mesh structure.Structure. The plastic core has various structural forms such as rectangular, hollow matrix, circular hollow circle, etc. This material overcomes the disadvantages of traditional blind gutters, featuring high surface pore rate, good water collection, large porosity, excellent drainage, strong compressive resistance, good pressure resistance, flexibility, adaptability to soil deformation, good durability, light weight, easy construction, and significantly reduced labor intensity for workers, leading to high construction efficiency. Therefore, it is widely welcomed by engineering departments and extensively applied. This product is manufactured by our factory.Jointly developed and manufactured with the Bridge and Tunnel Department of the Fourth Survey and Design Institute of the Ministry of Railways. This product is made by high-pressure extrusion molding, featuring different ribs and grooves on both sides to accommodate drainage, water stopping, and fixation requirements. It offers a certain degree of rigidity compared to other soft plastic sheet materials.Benefits include favorable for maintaining the drainage cavity, with a lower material density, relatively reduced costs, and characteristics such as cold resistance, corrosion resistance, anti-bacterial erosion, and resistance to aging when buried in tunnel linings, resulting in a long service life.
