Detachable anti-drop self-sealing connection method and structure for corrugated pipeline

Abstract

The invention discloses a detachable anti-drop self-sealing connection method and structure for a corrugated pipeline, and is characterized in that two self-sealing rings (4) are respectively mounted from two ends of a bidirectional socket and spigot joint shell (6), and then two anti-drop pressing rings (3) are respectively mounted on two end surfaces of the bidirectional socket and spigot joint shell (6), so that gaps are reserved between the anti-drop pressing rings (3) and the joint shell (6); the two-way socket and spigot joint is formed; two corrugated pipelines (1) are inserted in place through the two ends of the two-way socket-and-spigot joint respectively, the screws (2) on the two-way socket-and-spigot joint are locked, the anti-disengaging pressing ring (3) is made to be tightly attached to the end face of a shell (6) of the two-way socket-and-spigot joint, the self-sealing ring (4) is pressed, and socket-and-spigot connection and sealing of the corrugated pipelines are completed. Through the realization of the self-sealing structure, the self-sealing of the pipeline joint is realized by utilizing the accumulation of flowing silt in the pipe network, and the damage of the accumulation of the flowing silt in the pipe network to the sealing connection of the pipeline is avoided.

Description

technical field [0001] The invention relates to a detachable detachment-proof self-sealing connection method and structure of a corrugated pipe, belonging to the technical field of pipe sealing. Background technique [0002] Plastic double-wall corrugated pipes are widely used in major drainage and irrigation pipe network systems. Existing plastic double-wall corrugated pipes are continuously produced through extrusion molding. The connection between pipes mainly adopts socket connection, and the socket connection is completed by the socket plug and socket on the pipe; The main body of the pipe is extruded into one body, and the socket connection adopted is to insert a rubber ring sealing ring in the trough of the socket plug, and then the socket plug is inserted into the socket opening, and the plastic double-wall corrugation is realized through the elastic deformation of the rubber ring sealing ring Radial sealing of the pipe at the socket. However, with the passage of t...

Problems solved by technology

[0003] 1) The sediment contained in the sewage flowing in the pipe network will accumulate at the rubber sealing ring, and the radial sealing position of the rubber sealing ring will be squeezed axially by the pipeline, and the sediment accumulation extrusion force will increase with time , resulting in axial deformation and slippage of the rubber sealing ring, which will eventually lead to leakage of the pipe network at the connection position;

[0004] 2) Due to the limitations of the forming process, the socket is generally a solid-wall structure with thin wall thickness. Compared with the double-wall corrugated main body of the pipe, the socket has the weakest strength, is difficult to form, and has insufficient external pressure load capacity. Pipes, which have the potential to dislodge over time
