Water seepage rock mass resistivity dynamic monitoring method and device

The invention discloses a water seepage rock mass resistivity dynamic monitoring method and also discloses a water seepage rock mass resistivity dynamic monitoring device which comprises a pulling device and a positioning device, the positioning device is installed at the lower end of the pulling device, a pull rod is pulled upwards, and the pull rod drives a balancing weight and a rubber pad to move upwards together. After moving to a certain height, the pull rod is rapidly pressed downwards to enable the balancing weight to smash the upper end of the positioning box, the positioning box moves downwards at the moment, and therefore the jacking column in the inner cavity of an electrode groove can abut against the electrode to be automatically inserted into mud, a right-angle rod moves upwards, a first triangular block is clamped at the upper end of a feeding opening, and after the electrode is inserted, the handle is pulled upwards, a first spring rebounds to drive the feeding plate to reset, a first triangu
