Background

At present, more and more subway entrance/exit pedestrian passageways and street underground pedestrian passageways are constructed by adopting shield pipe-jacking machines, and the key for pipe-jacking tunnel construction is to reduce the friction force between a pipe-jacking pipe joint and the ground. Therefore, thixotropic slurry is injected in the pipe-jacking tunnel construction process, and the thixotropic slurry mainly plays two roles in the pipe-jacking construction process, namely, the thixotropic slurry plays a lubricating role, dry friction between a pipeline and a soil body is changed into wet friction, and resistance is reduced; and secondly, the support function is realized, the tunnel becomes stable under the grouting pressure, and the deformation caused by pipe jacking construction is reduced. The grouting device injects thixotropic slurry according to the actual conditions in the pipe jacking construction process. The injected thixotropic slurry diffuses towards the periphery by taking the circle center of the grouting hole as the center, and the diffusion diameter and the grouting amount are mainly related to the grouting pressure.
