Abstract

The invention relates to a rolling contact type electrical method real-time advanced detection carrying device for a TBM and a method thereof. The rolling contact type electrical method real-time advanced detection carrying device comprises rolling hydraulic electrodes, rolling wiring equipment, a combined pipeline and fixed electrodes. Rolling measurement electrodes and rolling power supply electrodes are mounted on a cutter head. The rolling power supply electrodes are mounted on a shield. A fixed power supply electrode B and a fixed measurement electrode N are mounted on a back matched trailer of the TBM. The rolling hydraulic electrodes and the rolling wiring equipment are in electrical signal and oil liquid pipeline connection between the cutter head and the TBM body. The device and the method are advantageous in that the rolling electrodes according to the invention can ensure contact coupling between electrodes and a tunnel face in TBM tunneling or cutter head repairing, thereby realizing carrying integration of the detecting system and the TBM, and realizing electrical method real-time advanced detection in rotation of a TBM construction cutter head.

Description

technical field [0001] The invention relates to the field of real-time advanced detection for the detection of unfavorable geological bodies in tunnels, in particular to a rolling contact electric real-time advanced detection carrying device and method for TBM. Background technique [0002] With the continuous increase of subway construction in major cities, the number of cross-river and sea-crossing tunnel projects continues to increase. The country's key construction projects, such as long-distance water supply, underwater transportation, and west-east gas transmission projects, will all involve crossing rivers. ; Railway, highway, municipal, water supply, gas supply, flood control, hydropower and other tunnel engineering construction. These all can make the quantity of tunnel (tunnel) increase substantially. TBM construction is the mainstream tunnel excavation method. TBM (Tunnel Boring Machine) mainly uses mechanical pressure to cut and break rocky soil. It is a highly ...
