Underground engineering induced polarization advance geological forecast wireless rapid acquisition system and method

Abstract

The invention discloses an underground engineering polarization advance geological forecast wireless rapid acquisition system, including a support, a seal ring and a wireless acquisition and communication module. One side of the support is provided with a non-polarizing electrode, and the other side of the support is provided with a vacuum generation module used for adhering the support to a tunnel face. The seal ring is arranged on the surface of the tunnel face and used for supporting the support. The wireless acquisition and communication module is arranged on the support and comprises a wireless transmission module and a data acquisition module, and the data acquisition module is connected with the non-polarizing electrode. The rapid acquisition system provided by the invention controls electrode switching through wireless communication, so that manual changing of electrode is prevented, automatic control of detection electrode acquisition, transmission and switching is achieved, each electrode is acquired by each corresponding independent single-way acquisition module, the traditional sequential acquisition mode is improved, and the acquisition time is greatly shortened. The rapid acquisition system provided by the invention is advantaged in that the whole detection process is fast, the efficiency is high, detection can be immediately performed after installation and can be completed during each construction process gap in the tunnel, and normal construction cannot be influenced.

Description

technical field [0001] The invention relates to the field of excitatory polarization advanced geological prediction for tunnel and underground roadway engineering, in particular to a wireless rapid acquisition system and method for underground engineering polarization advanced geological prediction. Background technique [0002] With the rapid development of the national economy and the strategic needs of national construction, my country's tunnel construction projects are increasing day by day, and the construction difficulty is becoming more and more difficult. It has become the country with the largest tunnel and underground construction scale and the fastest construction speed in the world. As of the end of 2013, my country has built 11,359 road tunnels with a total length of 9,606 kilometers; my country has 11,074 railway tunnels in operation with a total length of 8,939 kilometers; around a number of world-class water conservancy projects, more than 10,000 kilometers of...

AI Technical Summary

Problems solved by technology

[0005] 1) In the traditional detection process, the method of drilling holes on the face of the face is used to arrange electrodes, which requires a lot of drilling work on the face of the face, which is time-consuming and laborious;

[0006] 2) A large number of detection electrodes (more than 20) arranged on the face of the face are equipped with a large number of cables, which not only occupy the entire space in front of the face of the face during the detection process, but also make the process of detecting and releasing wires very complicated. At the same time, a large number of Cables and electrodes are difficult to transport and carry;

[0007] 3) The traditional electrode itself has a strong polarization effect, but the existing non-polarized electrode and the rock surface have a large grounding resistance, which makes it difficult to achieve excitation polarization acquisition under the condition of small grounding resistance. In addition, the measurement of the traditional electrode Running the pole requires manual operation, which is inconvenient to operate and low in work efficiency
