Description

Technical Field

[0001] The utility model relates to a socket-and-spigot pipe interface structure capable of preventing tree root puncture, and belongs to the technical field of municipal drainage pipes. Background Art

[0002] At present, municipal drainage pipes mostly use socket-type connections. After using this connection method for a period of time, it is often found that tree roots extend into the pipe interface, and even form a network of tree root curtains. In serious cases, the pipe section will be blocked, and even the pipe will rupture and disconnect, affecting the normal drainage function of the pipe. The main reason is that the pipe socket joint uses rubber rings or cement mortar tape to seal the pipe joint. After using it for a period of time, the interface is prone to slight displacement, disconnection, rupture, etc., and tree roots are easy to invade the pipe. Utility Model Content
