Can be used for tbm dynamic self-adaptive solid non-polarized electrode and using method

Abstract

The invention discloses a dynamic self-adaptive solid non-polarized electrode for TBM and a usage method. The telescopic linkage device drives the non-polarized electrode to move, and the non-polarized electrode is sent to the face of the tunnel; then the material is fed by A feeding pipe and B The tube adds accelerator and electrolyte to the electrolyte tank, and the electrolyte and accelerator are compressed by the pushing device. After the pushing is completed, wait for 3-5 minutes to make the electrolyte solidify completely, and then start detection; after the measurement is completed, control the expansion and contraction The cylinder of the linkage device drives the telescopic rod to move backward, and at the same time drives the non-polarized electrode to leave the face, so as to realize the removal of the non-polarized electrode and complete the detection task. The invention realizes contact measurement, and has the characteristics of mechanical automation control installation and removal, and at the same time satisfies the small range of measurement electrodes and high measurement accuracy, adapts to the complex conditions of unevenness of the tunnel surface, and satisfies the automation and mechanization of TBM construction requirements.

Description

technical field [0001] The invention relates to the field of electric field information measurement, in particular to a solid non-polarized electrode that can be used for TBM dynamic self-adaptation and a use method. Background technique [0002] Electrodes are an important part of electric field information measurement and reception, and are widely used in earthquake precursor observation, geophysical electrical exploration, engineering exploration, oil exploration, and geomagnetic exploration and other fields. Among them, for tunnel induced polarization advanced detection, electrode collection IP signal is an important component of tunnel induced polarization detection system, which is of great significance for tunnel disaster prevention and mitigation. [0003] In the process of excitation polarization signal collection, ordinary metal electrodes such as copper electrodes and lead electrodes are used as measurement electrodes, which cause inaccurate measurement data due t...

AI Technical Summary

Problems solved by technology

[0004] (1) The face of the TBM cutter head is uneven, and the contact electrode cannot adapt to the unevenness of the face, so good contact cannot be achieved, and the grounding resistance is large

[0005] (2) Traditional electrodes need to be manually installed and removed, and TBM construction electrodes have a low degree of automation, low efficiency, and high labor intensity

[0006] (3) The service life of the upper electrode of the TBM is short, and the later maintenance cost is high
