Anti-leaking plastic pipe

Abstract

The invention discloses an anti-leaking plastic pipe. The anti-leaking plastic pipe is characterized in that sealing mechanisms are arranged on the outer surface of one end of an inner pipe body in a matching manner, and one or more structures matched with the sealing mechanisms are arranged on an outer pipe body; a sealing cavity is formed between other parts of the inner pipe body and the outer pipe body, and sealant is stuffed in the sealing cavity. Through the adoption of the anti-leaking plastic pipe disclosed by the invention, injection sealing can be performed on the plastic pipe on site.

Description

technical field [0001] The invention relates to a plastic pipe, in particular to a leak-proof plastic pipe. Background technique [0002] At present, the pipes used in the domestic underground water supply and drainage pipeline system mainly include concrete pipes, reinforced concrete pipes and cast iron pipes. Due to their long construction period and large traffic volume, the underground concrete drainage pipes and cast iron water supply pipes in some road sections have been damaged and aged. , causing urban drainage blockage and bursting of water supply pipes, which not only bring a lot of inconvenience to the lives of citizens, but also cause the road foundation to sink and sewage to seep due to the complicated construction process, large number of pipe joints, and difficulty in timely treatment of anti-leakage. Leakage will also pollute soil quality and water sources and become a public nuisance. For this reason, the use of pipes with good pressure resistance, corrosio...

AI Technical Summary

Problems solved by technology

[0004] However, the plastic winding structure wall pipes in the prior art are generally straight pipes, so there are certain problems during construction, that is, the connection between pipes is troublesome and time-consuming.

The connection methods currently used generally include welding, socket connection, clamp connection and other connection methods. These connection methods must use a socket interface to connect with a straight pipe, so the preparation work required in the early stage of the connection construction is cumbersome. The installation and connection process is more complicated, and the installation time is longer, and because there are many construction interfaces, it also increases the risk of leakage at the sealing part of the pipe after installation
