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

The invention discloses a dynamic self-adaptive solid non-polarizing electrode available to TBM (tunnel boring machine) and a using method of the dynamic self-adaptive solid non-polarizing electrode. The using method comprises the following steps: driving a non-polarizing electrode to move by virtue of a telescopic linkage device, and feeding the non-polarizing electrode to a tunnel face; then, adding an accelerator and electrolyte into an electrolyte slot by virtue of a feeding tube A and a feeding tube B, pressing the electrolyte and the accelerator by virtue of a pushing-pressing device, after the pushing-pressing is completed, waiting for 3-5 minutes to completely solidify the electrolyte, and then starting detecting; after the measurement is completed, controlling a gas cylinder of the telescopic linkage device to drive a telescopic rod to move towards the rear side, simultaneously driving the non-polarizing electrode to leave the face to realize the removal of the non-polarizing electrode and complete the detection task. The dynamic self-adaptive solid non-polarizing electrode disclosed by the invention is used for realizing contact type measuring, has the characteristics of mechanically and automatically controlling installation and removal, and simultaneously satisfies the extremely small measuring electrode range and high measuring precision, satisfies the automatic and mechanical requirements of TBM construction, and is adaptive to an uneven complex condition of the face.
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...
