Socket and spigot type structural wall winding pipe and connecting method thereof

Abstract

The invention relates to a socket and spigot type structural wall winding pipe and a connecting method thereof. The socket and spigot type structural wall winding pipe comprises a socket, a spigot and a tubular material, wherein the socket and the spigot are connected to the ends of the structural wall tubular material through a socket lap joint surface and a spigot lap joint surface, an electric hot melting net is arranged on the inner side of the socket, a rubber ring groove for a matched rubber ring to be placed is formed in the outer wall of the spigot, and the electric hot melting net is embedded into the inner wall of the socket. The electric hot melting net is tightly matched with the electric hot melting surface of the spigot. The socket is further provided with an electric hot melting terminal connected with the electric hot melting net. The winding pipe can adopt the rubber ring for the socket and spigot method, can also adopt an electric hot meltingsocket and spigot method or the two methods, is more reliable to connect, higher in installing speed and is not affected by a working environment in the installing process, and the construction cost is reduced.

Description

technical field [0001] The invention relates to the technical field of pipes, in particular to a socket type structural wall winding pipe and a connection method thereof. Background technique [0002] The polyethylene structural wall winding pipe has the advantages of corrosion resistance, low frictional resistance, wear resistance, etc., has high ring stiffness, deep buried, and good overall molding process, high seam tensile strength and corrosion resistance, and longer life; With a variety of reliable and convenient connection methods. This kind of pipe has become a hot spot for investment in plastic drainage and sewage pipes. In the connection of this type of composite pipe, the joint pipe fitting and its connection structure with the pipe are very important. At present, there are A-type pipes and B-type pipes for polyethylene structural wall wound pipes. For the connection methods such as shrink bands or shrink sleeves or welding wire hot-melt welding sockets commonl...

AI Technical Summary

Problems solved by technology

For the connection methods such as shrink bands or shrink sleeves or welding wire hot-melt welding sockets commonly used for A-type pipes, there are very large safety hazards, and it is usually difficult to ensure that the closed water test is passed; while B-type pipes currently have two production processes , one using intermittent drum production, this method uses integrally formed joints, after forming, the required joint size is made by car, and then the S-shaped copper wire is manually fixed on the inner wall of the socket with a rivet gun, and there are many operating procedures. And because the rivets are easy to rust and cause the copper wire to fall off, another continuous production method of the B-type pipe has the first joint production method, and there is also the A-type pipe connection method
