[0002] A drain pipe refers to a pipeline system used to discharge waste water, rainwater or other liquids, and is usually installed in buildings, roads and other facilities. Their main function is to discharge waste water such as sewage and rainwater to keep the environment clean. The design of drain pipes usually utilizes the characteristics of fluids. For example, by using the slope and gravity inside the pipeline, the waste water is effectively discharged into the sewage treatment plant or water treatment facility for further treatment or recycling. The application fields of drain pipes are very wide, and they are not only used for internal drainage of buildings, such as the sewer pipes in toilets, kitchens, etc., but also used for external drainage of buildings, such as rainwater pipes and sewage pipes.

In the device of this document, by setting a shock-absorbing explosion-proof shell and spiral reinforcing rods, the buffering of impact force can be improved, thereby increasing the protection effect. However, the shock-absorbing explosion-proof shell and spiral reinforcing rods are closely attached to the pipe body, and no elastic telescopic gap is reserved, and the impact force is buffered only by the elasticity of the material itself, resulting in a poor buffering effect.
