Product performance of 1. plastic blind ditch

This product is made of high-pressure polyethylene extrusion, with different ribs and grooves on both sides to meet the needs of drainage, water sealing and fixing. Compared with other soft plastic plates, it has a certain rigidity, which is beneficial to maintain the drainage cavity. The proportion of the material is small, the cost is relatively low, it has the characteristics of cold resistance, corrosion resistance, bacterial corrosion resistance, and not easy to age when buried in the tunnel lining, and long service life.

Characteristics of 2. plastic blind ditch

1. The constituent fiber of the plastic blind groove is about 2mm wire strips, which are fused into a three-dimensional mesh body with the same principle as the truss principle of the steel structure. The surface opening is 95-97%, which is more than 5 times that of the perforated tube, 3-4 times that of the resin mesh tube, and the surface water absorption rate is extremely high.

2. As it is a three-dimensional structure, its void ratio is 80-95%, which forms the same space as management and is light, and its compressive performance is more than 10 times stronger than that of the resin of the pipe structure. Therefore, even if it is pressed due to overload, the residual void is more than 50% due to the three-dimensional structure, and there is no problem of water failure, and it is not necessary to consider being crushed by earth pressure.
