The plastic blind ditch is composed of a plastic core body wrapped with filter cloth. The plastic core is made of thermoplastic synthetic resin as the main raw material. After modification, in the hot melt state, thin plastic filaments are extruded through the nozzle, and then the extruded plastic filaments are welded at the nodes through the forming device , Forming a three-dimensional three-dimensional network structure. At present, the plastic core has a variety of structural forms such as rectangle, hollow matrix, circular hollow circle and so on. This material overcomes the shortcomings of traditional blind ditch. It has high surface opening rate, good water collection, large porosity, good drainage, strong pressure resistance, good pressure resistance, good flexibility, adapt to soil deformation, and good durability , Light weight, convenient construction, greatly reduced labor intensity of workers, and high construction efficiency. Therefore, it is generally welcomed by the Engineering Bureau and is widely used.
The characteristics of the plastic blind ditch: The fiber of the plastic blind ditch is about 2mm of filaments, which are fused and formed at each other to form a three-dimensional mesh body. The principle is the same as that of the steel structure truss. The surface opening rate is 95-97%, which is more than 5 times that of the porous tube and 3-4 times that of the resin mesh tube. The surface water absorption rate is extremely high. Because it is a three-dimensional structure, its porosity is 80-95%, the space and management are the same and it is light, and its compressive performance is more than 10 times stronger than that of the resin of the pipe structure. Therefore, the residual void is more than 50%, there is no problem of no water flow, and there is no need to consider that it will be crushed by earth pressure.
