Water level monitoring device suitable for laser measurement method and its construction method

Abstract

The invention relates to a water level monitoring device suitable for a laser measurement method and a construction method of the water level monitoring device, and belongs to the technical field of underground water level monitoring. The water level monitoring device suitable for the laser measurement method comprises a water level tube and a reflecting plate, wherein a plurality of guide grooves are formed in the inner wall of the water level tube; the reflecting plate floats on the water surface in the water level tube; the reflecting plate is provided with a plurality of connecting arms which are matched with the guide grooves. The reflecting plate serving as a laser reflecting medium is arranged in the water level tube, influence on the water surface and water quality can be eliminated, measurement precision is improved, and measurement speed is increased; moreover, the connecting arms of the reflecting plate are placed in the guide grooves, circumstances that the reflecting plate is inclined when moving vertically or swings during water level fluctuation, and the like can be avoided effectively, and the measurement precision is improved further. The construction method is simple in process, convenient to operate and high in water level measurement precision.

Description

technical field [0001] The invention relates to a water level monitoring device suitable for a laser measurement method and a construction method thereof, belonging to the technical field of underground water level monitoring. Background technique [0002] The groundwater level is the most direct data that reflects the state of the groundwater. It is a very critical data when monitoring the groundwater level, evaluating and calculating the amount of groundwater resources. For the monitoring of the groundwater level, the water level pipe is usually drilled and buried at the monitoring point, and then the distance between the water level in the water level pipe and the top of the water level pipe is measured by the water level monitoring instrument, so as to calculate the actual water level in the water level pipe. [0003] The traditional method of measuring the groundwater level is to hang a buzzer with a tape measure. After the buzzer is soaked in water, the circuit is conn...
