Vector-based adaptive adjustment method and system for tunneling attitude of shield tunneling machine

Abstract

The invention relates to a vector-based adaptive adjustment method and system for the tunneling attitude of a shield tunneling machine. The vector-based adaptive adjustment method and system for the tunneling attitude of the shield tunneling machine comprises the following steps that a jack on the shield tunneling machine is partitioned to form a plurality of jack regions; in the tunneling construction process of the shield tunneling machine, the attitude of the shield tunneling machine is analyzed in real time to obtain attitude adjustment information; and the advance speed relationship amongthe multiple jack regions is obtained by analysis according to the attitude adjustment information, the execution speeds of the jack regions are worked out according to a reference advance speed, andthe advance speed of the corresponding jack is controlled by means of the corresponding execution speed. According to the vector-based adaptive adjustment method and system for the tunneling attitudeof the shield tunneling machine, a deviation of the attitude of the shield tunneling machine is rectified by controlling the advance speed of the jack so as to realize active and expected attitude control of the shield tunneling machine; and the advance speed of the jack can be controlled more accurately compared with oil pressure control, so that the attitude adjustment effect of the shield tunneling machine is better.

Description

technical field [0001] The invention relates to the field of shield tunneling construction engineering, in particular to a method and system for self-adaptive adjustment of a tunneling attitude vector of a shield tunneling machine. Background technique [0002] The goal of deflection correction in tunnel construction is to make the tunnel construction axis as close as possible to the tunnel design axis (DTA). The actual tunnel construction axis generally approaches the DTA in a "snake" shape within the scope of quality control. The existing technology is to manually operate the deflection correction of the shield machine. The principle of the manual deflection control strategy for zone oil pressure is "diligent correction and slow correction". In fact, it is a method of repeated trial and error with the actual zone oil pressure. The operator's experience level in manual correction determines the amplitude and frequency of the "snake". [0003] The deviation correction meth...
