The tunnel engineering of long and large lines such as railways, highways and the like needs to carry out a borehole hydrogeological test and carries out water level measurement in the borehole; at present, manual measurement is generally adopted, and the measurement method comprises the following steps: the operators tie the core blocks on the measuring ropes and extend the core blocks into the drill holes; when the rock core blocks at the bottom of the rope reach the vicinity of the water surface, an operator lifts the rope up and down to determine the position of the water surface according to the tension change caused by buoyancy difference, and then the water level burial depth is determined according to the scale of the rope or the length of the rope measured by a tape measure.
However, manual measurement often has the following drawbacks:
(1) The measurement result data precision is lower: an operator only determines the water surface position by sense organs, so that the measured value and the true value are often greatly different, and the calculation result is influenced;
