Mouth-protecting pipe piece, its making method and using method

Abstract

The invention is a flared pipe fitting for connecting plastic coiled structured wall pipes, comprising: straight pipe segment, flared segment and socket segment connected into a whole, where the diameter of the straight pipe segment is adapted to that of the connected pipe, the inner diameter of the socket segment is greater than the outer diameter of the connected pipe, and the making method of the flaring pipe fitting: using the plastic for making plastic coiled structured wall pipe as raw material, and adopting cast moulding method to make it. And its use method comprise: fusion-welding it with thermal shrinking belt or electric fusion belt for plastic coiled structured wall pipe to compose a plastic coiled structured wall socket pipe, and implementing socket connection between it and another one in construction. In use, it reduces the risk of seepage happening after pipe connection and installation.

Description

technical field [0001] The invention relates to a plastic pipe fitting, in particular to a flaring pipe fitting used for connecting plastic winding structure wall pipes and its manufacturing method and usage method. 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 sour...

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
