Guiding system and method for connecting passage construction with pipe jacking method based on discontinuous inter-visibility

Abstract

The invention relates to a guiding system and a guiding method for connecting passage construction with pipe jacking method based on discontinuous inter-visibility.. A guiding target is formed by adopting a fiber gyroscope and a double-shaft sensor and the guiding target is arranged in a machine head of a pipe jacking machine to realize the guiding in a narrow construction space of a connecting passage. The azimuth angle of the guide target in a construction coordinate system is obtained by utilizing the fiber gyroscope, the gradient angle and the rolling angle of the guide target are obtainedby utilizing the double-shaft sensor, and the machine head center local coordinate value and the tail center local coordinate value which are accurately calibrated before tunneling construction are combined, so that the construction three-dimensional coordinates of the machine head and the tail center can be solved without the observation of a total station, therefore the attitude information ofthe pipe jacking machine is obtained, and the guiding of the pipe jacking machine is realized. The attitude information of the pipe jacking machine can be obtained under the condition of not needing the observation of the total station, so that the problem of low measurement accuracy caused by poor stability of an observation platform (a platform for installing the total station) is solved, and the problem of target shielding in construction is also solved.

Description

technical field [0001] The invention relates to the technical field of tunnel engineering, in particular to a guiding system and method for the construction of a communication channel based on the pipe jacking method under discontinuous view. Background technique [0002] With the development of pipe jacking construction, pipe jacking guidance has transitioned from manual guidance to automatic guidance. At present, the most versatile and mature pipe jacking guidance system in the world is the SLS-RV jacking system developed by German VMT company. Tube guidance system. The SLS-RV guidance system uses the laser emitted by the automatic total station with tunnel laser transmitter installed on the moving pipe section wall to provide a stable reference for the tunneling of the pipe jacking machine, and the positioning of the automatic total station is through the inclinometer, reference The prism and the distance sensor are realized, but due to the construction process of the pi...

Problems solved by technology

[0007] The purpose of the present invention is to overcome the defects of the prior art, to provide a guiding system and method for the construction of the communication channel based on the discontinuous line-of-sight pipe jacking method, and to solve the problem caused by the poor stability of the observation platform in the narrow space construction of the existing communication channel. The measurement accuracy is low and the target is blocked during construction, which makes it difficult to apply the commonly used measurement devices
