Embodiment Construction
[0027] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0028] refer to Figure 1 to Figure 2 , is a method for monitoring the posture of a pipe jacking machine 1 disclosed in the present invention, comprising the following steps:
[0029] The preparatory step is to stick a plurality of reflective sheets 2 on the side of the pipe jacking machine 1 away from the pipe jacking.
[0030] Specifically, a plurality of reflecting sheets 2 are divided into three groups, including a first group 3, a second group 4 and a third group 5, wherein the first group 3 is used to measure the torsion angle 9 of the pipe jacking machine 1, and the second group 4 is used to measure the pitch angle 8 of the pipe jacking machine 1 jacking, and the third group 5 is used to measure the elevation, mileage and axis deviation of the pipe jacking machine 1 jacking.
[0031] Further, in this embodiment, the first group 3 includes at least tw...

The invention relates to a method for monitoring the posture of a pipe jacking machine, which comprises the following steps: a preparation step: a plurality of reflector plates are attached to one side, deviating from a jacking pipe, of the pipe jacking machine; a measurement step: after the pipe jacking machine jacks for a preset distance, the attitude of the pipe jacking machine is measured through a total station arranged in the starting well, and the attitude of the pipe jacking machine is returned to when the attitude of the pipe jacking machine deviates; the reflector plate and the total station are matched to measure the attitude of the pipe jacking machine, so that the monitoring method is simple, the construction cost is reduced, and the construction speed is increased; and meanwhile, after the pipe jacking machine jacks for a preset distance, the posture deviation of the pipe jacking machine is adjusted, so that the jacking axis is effectively controlled, and the construction quality is improved.
Description
technical field [0001] The invention relates to the technical field of construction engineering, in particular to a method for monitoring the attitude of a pipe jacking machine. Background technique [0002] At present, with the continuous advancement and development of urbanization in our country, in order to avoid the destruction of urban buildings, it is necessary to lay water supply and drainage pipelines, natural gas and oil pipelines, communication cables and other pipelines underground in cities. The pipe jacking method plays an important role in the construction of comprehensive pipe corridors, underground passages and other projects because of its advantages of no need to excavate the ground, less land occupation, less traffic impact, fast excavation speed, economy and environmental protection. [0003] However, the pipe jacking method is used for construction. Due to the change of the soil quality of the ground, the pipe jacking machine is prone to lateral deflecti...
