Socket and spigot type jacking pipe and assembling method thereof

Abstract

The invention provides a socket and spigot type jacking pipe and an assembling method thereof, and belongs to the technical field of jacking construction. The socket and spigot type jacking pipe comprises a socket, a spigot and a pipe body and further comprises a force bearing ring. The force bearing ring is of an annular structure with an L-shaped cross section, the side A of the force bearing ring is matched with the lining layer of the pipe body and is parallel to the axis of the pipe body, and the edge B of the force bearing ring is matched with the inner end surface of the socket, is perpendicular to the axis of the pipe body and is used for bearing axial force transmitted by a spigot of an adjacent jacking pipe in the jacking operation process. According to the socket and spigot typejacking pipe, jacking force at the end of the spigot can be evenly dispersed and transmitted to the socket, internal stress concentration of the socket caused by the jacking force is prevented, and the socket is protected during connection operation. Moreover, the inner diameter of the socket is reduced due to the L shape of the force bearing ring, the spigot abuts against the edge B of the forcebearing ring and can be effectively prevented from moving inwards, and the coaxiality of two jacking pipes in the connecting process is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of jacking construction, and more specifically relates to a socket-type pipe jacking and an assembly method thereof. Background technique [0002] With the development of urban construction, the underground space trenchless technology has attracted more and more attention and has been widely used. How to install and replace urban water supply, drainage, gas and communication facilities under the premise of minimal damage to the urban environment has put forward new requirements for underground engineering construction technology. [0003] Pipe jacking construction technology is a non-excavation technology for laying underground pipelines that better protects the environment. Under the condition of not disturbing or slightly disturbing the soil structure outside the pipe, with the help of the thrust of the jacking equipment such as the main jacking pump, the tool pipe or roadheader is passed from the working...
