性能特点  FEATURES

1. The shape structure is square with arc corners, which is neat and convenient to arrange, takes up only 10% of the cement pipe position, and the excavation volume is small, which effectively saves urban underground space resources and has little impact on road traffic and municipal administration.

2. The pipes are light in weight and easier to handle than metal pipes and cement pipes. The construction and installation are simple, the construction intensity is small, and the project cost is low.

3. It has good toughness and bending performance. A section of 6-meter-long pipe has a bending chord height of more than 1.2 meters. Special elbows can be equipped for special direction changes. It can be easily avoided when encountering bends or crossing other pipelines during construction.

4. The bending modulus of elasticity is good, which completely solves the defect of no torsion elasticity of metal steel pipes.

5. Strong corrosion resistance, good insulation and flame retardancy, antistatic.

6. Compressive performance. The depth is only required to be 0.3-0.5 meters. There is no need to make a foundation and cement envelope. It can be opened to traffic by backfilling 20 cm of fine sand first and then backfilling.
