Concrete pipe and manufacturing process thereof

Abstract

The invention discloses a concrete pipe and a manufacturing process thereof. According to the technical scheme, the concrete pipe comprises a pipe body, and a socket end and a spigot end are arrangedon the pipe body. The pipe body is composed of a reinforcing steel bar keel and a concrete layer covering the reinforcing steel bar keel. The peripheral face of the spigot end of the pipe body is fixedly connected with a water stopping pipe. The concrete pipe and the manufacturing process thereof have the advantage of improving the waterproof performance of an inserting opening of the concrete pipe.

Description

technical field [0001] The invention relates to the field of underground drainage pipes, in particular to a concrete pipe and a manufacturing process thereof. Background technique [0002] Concrete pipes, also known as cement pressure pipes and reinforced concrete pipes, can be used as sewer pipes in urban construction foundations, as well as upper water pipes used in some special factories and mines. Cement pipes can generally be divided into: flat-mouth cement pipes, flexible-mouth cement pipes, socket-mouth cement pipes, etc. [0003] The existing concrete pipe includes a socket and a socket, a sealing ring is sleeved on the socket, and an accommodating groove for accommodating the sealing ring is opened on the outer wall of the socket. In order to realize the mutual insertion between the socket and the socket between the concrete pipes, the wall thickness of the concrete pipe socket is relatively thin, so that the concrete pipe socket is prone to cracks in the collision...

AI Technical Summary

Problems solved by technology

In order to realize the mutual insertion between the socket and the socket between the concrete pipes, the wall thickness of the concrete pipe socket is relatively thin, so that the concrete pipe socket is prone to cracks in the collision during long-distance transportation. , resulting in quality problems of concrete pipes, which cannot meet the requirements for use
