How to reduce the resistance of pipe jacking machine construction

Due to the different natural conditions in each region of China, mainly the difference in geology and hydrology, soil type, substrate changes are different, and the difference in water table and tidal influence is also big, so the formation of pipe jacking resistance calculation is complicated in the process of pipe jacking machine construction, in order to reduce the resistance of pipe jacking machine jacking and increase the length of pipe jacking machine jacking, Bazhou Huazhong non-excavation equipment plant generally adopts the following measures to ensure that the jacking Pipe jacking machine construction process. 1、Paint lubricant on pipe jacking machine wall to reduce the friction resistance between pipe wall and soil; 2、Pressure slurry with thixotropic slurry to fill in between pipe jacking machine wall and soil to reduce friction resistance coefficient. 3、Adopt relay indirect force to reduce the jacking reaction force of the backseat wall of pipe jacking machine. 4、Adopt two-way pipe jacking , docking underneath. 5、Diligent digging, diligent top, diligent measurement, diligent correction, reduce pipe jacking machine pipe deviation and pipe jacking machine pipe section misalignment.
