Lu'an stone plastic blind trench specifications pictures stone plastic blind trench drainage plastic blind trench plastic blind trench price
High pressure resistance, good flexibility, adapts to soil deformation, durable, lightweight, easy to install, this material overcomes the shortcomings of traditional blind gutters, featuring high surface pore rate, good water collection, large void ratio, excellent drainage, strong compressive strength, and different ribs and grooves on both sides.
To meet the needs of drainage, water stopping, and fixation, this material has a certain rigidity compared to other soft plastic boards, which is beneficial for maintaining the drainage cavity. It has a lower density, resulting in reduced costs. It features cold resistance, corrosion resistance, resistance to bacterial erosion, and is not prone to aging when buried in tunnel linings, offering a long service life.
The fiber composition of plastic blind grooves consists of strands about 2mm in length, which are fused together at their junctions to form a three-dimensional mesh structure. This principle is similar to the truss principle used in steel structural construction. The labor intensity for workers is significantly reduced, and construction efficiency is high, thus gaining widespread popularity among engineering departments and extensive application.
This product is made by high-pressure extrusion molding, with a surface perforation rate of 95-97%, which is five times more than that of hollow pipes and 3-4 times that of resin mesh pipes, offering an extremely high water absorption rate. The plastic blind channel is composed of a plastic core wrapped with filter fabric. The plastic core is primarily made of thermoplastic synthetic resin, modified and extruded into fine plastic filaments in a molten state through a nozzle. These filaments are then fused at junctions by a molding device to form a three-dimensional mesh structure. The plastic core comes in various structures such as rectangular, hollow matrix, circular hollow, and more.
