[0002] PE drainage pipe is a kind of drainage pipeline made of polyethylene (PE) material. In terms of performance, it has corrosion resistance, can effectively resist the erosion of various chemical substances, and can work stably for a long time in different acid-base environments. It has good flexibility and can withstand a certain degree of deformation without breaking, which makes it suitable for complex installation environments. And it also has good anti-aging property, can maintain stable performance for a long time. In terms of application, PE drainage pipe is widely used in municipal drainage engineering, such as urban rainwater and sewage discharge system; also used in building drainage, including indoor drainage pipeline and drainage facilities around buildings and many other fields.

[0003] PE drainage pipe is usually connected by hot melt butt joint process. This method has obvious advantages, the connection part of pipe material and pipe fitting is melted together by high temperature, the connection is very firm, the sealing performance is excellent, can effectively prevent liquid leakage, ensure the stable operation of drainage system. However, this method is not perfect. In the process of hot melt butt joint, if the operation is not proper, such as heating temperature, time or butt joint pressure control is not good, it is easy to produce weak link at butt joint. Once the pipeline is put into use and leakage occurs, due to its underground or concealed position, the maintenance difficulty is great. And if there is a blockage in the pipe, due to the fixed installation characteristics of the pipeline, it is not convenient to carry out maintenance work. UTILITY MODEL CONTENT
