Device and method for correcting cutterhead jacking direction in real time during manual pipe jacking construction

Abstract

The invention discloses a device and method for correcting the cutterhead jacking direction in real time during manual pipe jacking construction, and relates to the field of municipal road drain pipeline construction. The method comprises the following steps that four hand-operated jacks are uniformly arranged and fixed to the inner side of the circumference of a cutterhead, a protection barrel ofthe cutterhead extends to cover the four hand-operated jacks, and the cutterhead is connected with a pipeline through the four hand-operated jacks; and when the cutterhead is jacked into a first pipeline section, in the deviation correcting process, the center line and the elevation are measured every time the cutterhead is jacked in by 20-30 cm, the hand-operated jacks are operated manually to slightly adjust the angle of the cutterhead according to the measurement results so that the pipeline jacking direction can be corrected. Through the device and method for correcting the cutterhead jacking direction in real time during manual pipe jacking construction, the constructed pipeline can be precisely positioned, the underground extending deviation of the pipeline is corrected in real time, and the jacking direction in the whole pipeline jacking process is effectively controlled.

Description

technical field [0001] The invention relates to the field of municipal road drainage pipeline construction, in particular to a device for real-time correction of the jacking direction of a cutter head during manual pipe jacking construction. Background technique [0002] In the construction of modern cities, with the development of the economy and the increasing population, the resources that can be developed on the ground are becoming less and less, and the rational use of underground space has become a way to solve the problem of laying urban pipelines. A large number of road excavations will cause traffic jams, and the excavated spoils will pollute the urban environment and affect the lives of residents. [0003] The traditional pipeline laying method is to excavate along the pipeline laying direction, hoist the pipeline into the trench, and then backfill it, which takes a lot of time. Once large-scale rainfall occurs during the construction process, it will greatly affec...

Problems solved by technology

[0006] Deviation correction has always been a difficult problem in manual pipe jacking construction. The traditional deviation correction method is generally based on the existing device, and then adopts the excavation correction method (increasing or decreasing the amount of excavated soil for different parts), the forced deviation correction method (using brackets) , square wood, and jacks exert external force on the outside of the pipeline), adjust the position of the jacking force (adjust the position of the resultant force of the jack), etc. to correct the deviation of the pipeline jacking. The disadvantages of the above methods are unsafe, low efficiency of deviation correction, difficulty in deviation correction, and Correction in motion, etc.
