Description

Technical Field

[0001] This utility model relates to the field of socket pipe technology, specifically reinforced concrete socket pipe. Background Technology

[0002] Reinforced concrete spigot and socket pipes are a very common and important type of precast concrete pipe, widely used in drainage, sewage, water diversion, and integrated pipe gallery projects in municipal, water conservancy, and transportation fields. The pipe has a socket or spigot end with a certain connection space reserved at one end, and the other end of the pipe is inserted into the socket to achieve connection. This connection method has the advantages of simple construction, good sealing, and strong connection.

[0003] Common spigot and socket pipe connections often leave relatively large gaps, requiring additional equipment and materials to seal the pipes during the connection process, which is quite cumbersome. Therefore, we propose reinforced concrete spigot and socket pipes to address these issues. Utility Model Content
