Abstract

The present invention proposes one kind of pipe for drainage system and its production process. The polymer concrete pipe is produced with resin, sand and supplementary material. It may be used in trench, draining pipe, rhone and U-shaped drainage trough. It has the advantages of high strength, high corrosion resistance, high weather resistance, long service life, etc.

Description

technical field [0001] The invention relates to a drainage system pipe and its manufacturing method Background technique [0002] Drainage system is an important part of municipal construction. It is made of raw materials into a certain length of U-shaped trough. When in use, the prefabricated trough is spliced ​​into a pipe. In this way, the splicing of prefabricated parts is not only convenient for transportation, but also reduces the construction time. . [0003] At present, the prefabricated tanks used in China are made of cement, cast iron, PVC and other materials, but these materials generally have the problems of poor windproof performance, poor corrosion resistance, and insufficient compressive and flexural strength. Contents of the invention [0004] Aiming at the defects and deficiencies in the prior art, the object of the present invention is to propose a drainage system pipe and its manufacturing method, which are made of resin, which is environmentally friend...
