Bozhou Black Covering Plastic Drainage Pipe Price
1. Composition fibers of plastic blind trench
For strand thickness of about 2mm, they are fused together at mutual junctions to form a three-dimensional mesh structure, with a principle similar to the truss principle in steel structural construction. The surface porosity is 95-97%, which is more than five times that of a hollow pipe and 3-4 times that of a resin mesh pipe, with an extremely high water absorption rate. 2. Due to its three-dimensional structure, the porosity is 80-95%, making it space-efficient and lightweight, with compressive strength 10 times greater than that of resin pipe structures. Therefore, even under overloading, the residual porosity can still reach over 50% due to its three-dimensional nature.
No issues with waterlogging, no need to worry about being damaged by soil pressure. 3. High compressive strength, with a compression rate below 10% under 250KPa pressure. 4. Added anti-aging agents for durability, ensuring stability even after decades underwater or in soil. 5. Compressive yet flexible, suitable for curves and bends, easy to handle, and can be backfilled with a bulldozer if the backfill depth is around 10cm. 6. Due to these characteristics, it addresses various issues that traditional blind channels have encountered.
If uneven settlement or partial blockage due to overloading leads to crushed material causing complete absence of voids and functional disruption, the issue can be addressed with plastic blind trench materials. 7. Since the material is formed using thermal melting without the use of adhesives, it will not deteriorate due to adhesive aging or delamination.
