Construction method for preventing retreat of pipe pushing machine and pipe joints

Abstract

The invention provides a construction method for preventing retreat of a pipe pushing machine and pipe joints. The construction method includes: before pushing of the pipe pushing machine, mounting fixed bearing modules, a slide-resistance integrated module and a rotating module: setting two connecting steel plates in each fixed bearing module, setting a rotating arm and anti-slipping circular steel plate in the rotating module, and setting a slider and a stopping arm in the slide-resistance integrated module; pushing and measuring of the pipe pushing machine and the pipe joints; and preventing retreat of the pipe pushing machine or the pipe joints. With no need to modify existing pipe pushing machines or pipe joints, retreat of the pipe pushing machine and various types of pipe joints is effectively prevented when the pipe pushing machine goes out of a cavity, normal posture and accurate axis of the pipe pushing machine and the pipe joints are guaranteed, and construction efficiency is improved.

Description

technical field [0001] The invention relates to a construction method in the technical field of underground construction engineering, in particular to a construction method for preventing a pipe jacking machine and a pipe joint from retreating. Background technique [0002] Compared with the shield method, the pipe jacking method has the characteristics of fast construction speed and strong economy, and is widely used in the construction of small-diameter tunnels in soft ground. During pipe jacking construction, the pipe jacking machine is generally ejected from the pipe jacking working well first, and the subsequent pipe joints are jacked into the underground tunnel joint by joint following the pipe jacking machine. During jacking, the pipe joint is pushed forward by the jack installed in the working well, but when the subsequent pipe joint is placed, as the jack is loosened, the earth pressure on the front of the pipe jacking machine is greater than that of the pipe jackin...

Problems solved by technology

"Because the corbel device and chain hoist anti-retraction device described in this patent all need to transform the existing pipe joints one by one, there are disadvantages such as heavy transformation workload, low construction efficiency, low reliability, and waste of materials.

The corbel device and chain hoist anti-retraction device described in this patent are more suitable for the anti-retreat of steel pipe joints. For example, the device is applied to reinforced concrete pipe joints, glass steel sand pipe joints, plastic pipe joints, prestress For the stop of pipe joints such as steel cylinder concrete pipe joints, it is necessary to set additional connecting supports on the pipe wall of the pipe joints, which will increase the construction process, resulting in reduced construction efficiency, reduced reliability and material waste of
