Background
The pipe jacking construction is that a hydraulic jack or equipment with jacking and traction functions is adopted, a pipe jacking working well is used as a bearing wall, and pipes are jacked into a soil layer one by one according to the designed elevation, direction and gradient until the pipe reaches the destination.
The magnitude of the jacking force during construction obviously influences the quality and progress of construction, the key of jacking force control is to reduce the jacking resistance to the maximum extent, and the most effective method for reducing the jacking resistance is to perform grouting. The grouting makes the peripheral outer wall of the pipe form a slurry lubricating sleeve, thereby reducing the frictional resistance during jacking. Particularly, after the pipeline is jacked into the soil, thixotropic slurry must be injected between the outer wall of the pipeline and the soil wall, so that a closed slurry sleeve is formed. The friction resistance between the thixotropic slurry and the pipe wall is small, so that the jacking force is greatly reduced.
In actual grouting construction, when the construction geology with soft soil body, particularly construction of a backfill region penetrating through a burial pit (the current state burial pit has the depth of more than 10 meters, is mostly in a long and narrow shape, and has vertical and steep burial pit walls and basically no slope), the requirement on grouting construction is higher, otherwise, grouting can occur to cause pipeline foundation or roadbed settlement, and therefore the road construction quality is influenced.
However, the existing grouting construction is only provided with a pressure valve in a main pipeline, and the secondary pipeline of each grouting hole is not provided with a pressure valve, so that the grouting pressure of each grouting hole cannot be accurately monitored, and the grouting pressure is difficult to find in the first time after abnormity, so that the damage of an ancient tomb can be caused, even the settlement of the geology is caused, and the construction potential safety hazard exists.
