1. The composition fiber of plastic blind ditch is a wire strip of about 2mm, which is formed by melting and bonding with each other, forming a three-dimensional network. Its principle is the same as the truss principle of steel structures. The surface porosity is 95-97%, which is more than 5 times that of perforated pipes and 3-4 times that of resin mesh pipes. The surface water absorption rate is extremely high.
2. Due to its three-dimensional structure, the void ratio is 80-95%, making it easy to manage and compact in terms of space. Its compressive performance is more than 10 times stronger than that of resin in pipe structures. Therefore, even if it is compressed due to overload, the residual void ratio still exceeds 50% due to its three-dimensional structure. There is no problem of water blockage, and there is no need to consider being crushed by soil pressure.


3. High compressive strength, with a compression rate of less than 10% under a pressure of 250KPa.
4. With anti-aging agent, it is durable, and can be stable even if it is placed under water or in the middle of soil for decades.
5. Compression resistant and flexible, it can also be used for construction in bends and other curved areas, making it very lightweight. If the backfilling depth is about 10cm, a bulldozer can also be used for backfilling.
6. Due to the above characteristics, various problems that have occurred in traditional blind ditches in the past, such as uneven settlement or partial blockage caused by overloading, no gaps caused by compression, and functional interruption, can be solved through plastic blind ditch materials.
7. Due to the use of hot melt forming without the use of binders, it will not cause collapse due to aging and peeling of the binders
