Problems solved by technology

In principle, the tunnel guidance systems in Britain and Germany use laser pointing, which has high precision, but the system composition is complex; Japan uses gyroscopes, level tube level gauges, inclinometers, deflection gauges, and propulsion jack stroke gauges. Direction detection system, the system structure is simple, but the accuracy is low, the cumulative error is large, and the horizontal sliding that occurs during the propulsion process of the shield cannot be detected, and manual measurement is required for calibration

specific Embodiment approach

[0028] The specific embodiment: the present invention will be further described in conjunction with accompanying drawing now

[0029] The measuring robot Leica TCA 1800 (total station 2) with remote control and automatic function is installed in the built tunnel to automatically measure the three targets pre-installed in the shield machine 8—metal reflector 5 and metal reflector 6 and the spatial position of the metal reflector 7, according to the rigid body space solution theory and the vector solution algorithm, the attitude parameters of the shield are calculated by the program pre-programmed by the total station 2, and are wirelessly transmitted through the signal control box 1 of the total station and the radio station 13. Send to the industrial control computer 12, the cycle period of the total station 2 measuring the attitude parameters of the shield can be set according to the needs, wherein the metal reflector 5, the metal reflector 6 and the metal reflector 7 can be i...

Abstract

The invention relates to a method for real-time automatic correcting the figure of shield, and relative device, belonging to the shield driven technique. It is characterized in that: using the full-station device in the tunnel to automatically detect the spatial positions of three objects in the shield; using the program based on the spatial vector theory to automatically calculate the shield figure parameters. There are two shield figure automatic correction modes: pressure section control mode and jack group control mode, and it uses special shield figure automatic correction software to control the figure of shield. The invention can avoid the defect that correcting the axes with manual work with big vibration, to improve the operation quality, shorten working period, reduce the labor, decrease working strength and apply on-site management.

Description

Technical field: [0001] The invention belongs to the technical field of shield tunneling, and is precisely an automatic deviation correction technology for the operation posture of a shield machine. Background technique: [0002] The real-time automatic deviation correction method of the shield attitude refers to automatically completing the measurement and data collection of the real-time attitude of the shield without manual intervention, and comparing the actual deviation with the tunnel design axis. Through the pre-set deviation correction program, The shield propulsion jack automatically generates a moment opposite to the direction of the shield posture deviation during the propulsion process, so as to realize the automatic correction of the shield posture. [0003] To achieve automatic deviation correction, it must first be based on the automatic precision measurement technology of shield attitude. For a series of technical products and equipment such as the automatic...
