Connecting structure of winding pipe and connecting method thereof

Abstract

The invention discloses a connecting structure of a winding pipe and a connecting method thereof. The connecting structure comprises a first pipe body and a second pipe body which are interconnected,wherein a first pipe joint is arranged at the end, connected to the second pipe body, of the first pipe body; a second pipe joint is arranged at the end, connected to the first pipe body, of the second pipe body; the first pipe joint and the second pipe joint are coaxially fixedly connected by thermal smelting. According to the connecting structure, the first pipe joint and the second pipe joint are coaxially arranged, and the part where the first pipe joint and the second pipe joint are connected is connected by thermal melting; the pipe joints are arranged at the connecting part through theabovementioned connecting manner, and thus the two connected pipe bodies are provided with two connecting ends, and effective positioning can be realized during the connecting, and as a result, the technical requirements on connection can be effectively decreased, and the problem that inaccurate positioning leads to deviation, resulting in the leakage at the connecting parts, can be avoided; the thermal melting type connecting manner enables effective mixing of the materials at the connecting parts, so that the strength of the connecting parts can be effectively improved, and as a result, thepressure to the inside of the pipeline can be effectively increased, and the demand of actual use can be met.

Description

technical field [0001] The invention relates to the technical field of manufacture and connection of water supply and drainage pipes, in particular to a connection structure of winding pipes, and also relates to a connection method including the above connection structure. Background technique [0002] Buried drainage pipes and buried cable protection pipes for electric power and communication, etc., especially for large-diameter buried pipes, because the pipe wall needs to bear soil pressure, the pipe wall is required to have a high pressure bearing capacity, and the pipe wall must have a relatively high pressure resistance. In order to ensure that the pipe wall meets the requirements of buried pressure bearing capacity, reduce the thickness of the pipe wall, and reduce the manufacturing cost of the pipe, plastic-steel winding pipes have appeared. [0003] Existing winding pipes are usually manufactured into finished pipes according to the standard length (usually 6-8 meter...

AI Technical Summary

Problems solved by technology

However, this kind of connection structure has defects such as that the connection is prone to leakage, and in order to ensure the stability of the connection, the pressure that the pipeline can withstand is below 0.05MPa.
