Description

Technical Field

[0001] The present application relates to the technical field of pipe jacking construction in construction engineering, and in particular to a dynamic deviation correction device for pipe jacking construction in complex geological conditions. Background Art

[0002] Pipe jacking construction refers to the construction of horizontal or inclined pipes underground. The pipe jacking method is usually used to install drainage pipes, water supply pipes, gas pipes, etc., and can be carried out underground by digging an entrance pit on the ground. During the construction process, construction workers will use special mechanical equipment to push and lay pipes to complete the installation of the pipes.

[0003] The existing Chinese public patent (authorization announcement number: CN108662282B) mentions a jacking device and a jacking construction method for silt ground. After the jacking device is pushed into the reserved position, the bolts are removed, and multiple seepage pipes filled with water-absorbing materials are pushed outward from the installation through hole to open the baffle and insert into the silt ground. Then the baffle continues to block the installation through hole under the action of the torsion spring, and the seepage pipe is directly inserted into the silt. The seepage pipe is used to absorb moisture in the silt on the one hand, and on the other hand, it can be used to fix the silt ground, avoid displacement of the pipe body, increase construction speed, and reduce resource waste.

[0004] When pipe jacking is carried out in silty soil, the pushing end of the pipe jacking needs to be pushed underground, so a drill bit is generally provided at the pushing end of the pipe jacking. However, the cutting area of ​​the drill bit is small, which limits the number of soil layers that can be broken and removed each time the pipe is pushed forward. If the soil is hard or sticky, a single drill bit may not be able to effectively break the soil, resulting in a slower pushing speed and thus lower work efficiency. Utility Model Content

[0005] The purpose of the present application is to provide a dynamic deviation correction device for pipe jacking construction in complex geology in order to solve the problem that a single drill bit may not be convenient for effectively breaking the soil if the soil is hard or sticky, resulting in a slow advancement speed.
