Advanced detection magnetic resonance device system for TMB construction tunnel

Abstract

The invention relates to the technical field of tunnel boring machine detection systems and particularly relates to an advanced detection magnetic resonance device system for a TMB (tunnel boring machine) construction tunnel. The system comprises a transmitting coil, a receiving coil, a magnetic resonance host, an artificial field source, a nuclear magnetic resonance inversion module and the like, wherein the transmitting coil and the receiving coil are arranged behind a cutterhead of the tunnel boring machine and connected with the magnetic resonance host through a high-speed conductive slip ring; an alternating current is led into the transmitting coil; a nuclear magnetic resonance signal is received by the receiving coil; the nuclear magnetic resonance inversion module obtains the water content of a water-bearing geologic body in front of the tunnel face; and real-time and quantitative advanced detection of the water-bearing geologic body is realized, and the construction safety of the tunnel is guaranteed.

Description

technical field [0001] The invention relates to the technical field of roadheader detection systems, in particular to a magnetic resonance device system for advanced detection of TBM construction tunnels. Background technique [0002] With the in-depth development and implementation of the western development strategy, the focus of my country's engineering construction has gradually shifted to the western mountainous areas and karst areas with complex geological conditions. The construction of tunnels and other underground projects is facing challenges such as large buried depth, long axis, and strong karst. In addition, it is difficult to find out the engineering geological and hydrogeological conditions along the tunnel in the geological survey work in the early stage of construction, which will lead to many geological disasters during the tunnel construction, such as: water and mud inrush, landslides, rockbursts, etc. Among them, water and mud inrush is one of the main geo...
