Problems solved by technology

However, the tracer concentration dilution of this method is affected by factors such as molecular diffusion and stirring, and the measurement results are not very stable.
The principle of the radioisotope porous tracer method is basically the same as that of the chemical method. Because the former uses a counter tube as a detection device consisting of a probe and a calibrator, the operation method is more convenient, and at the same time, artificial errors in chemical analysis are avoided. The use of radioisotopes will cause harm to the environment and experimenters

Abstract

The invention relates to an underground water flow speed and flow direction detection intelligent sensor used for landslide monitoring. The sensor comprises a sensor shell, and a switch-on and switch-off electromagnetic valve, a liquid storage tank end cover, a liquid storage tank, a one-way connection valve, a circular dial, a camera and a camera installation frame which are sequentially arranged in the sensor shell from top to bottom. A plurality of through holes for making the inner portion and the outer portion of the sensor shell communicated are formed in the middle of the sensor shell in the circumferential direction. A colored tracer agent is arranged in the liquid storage tank. The switch-on and switch-off electromagnetic valve triggers the one-way connection valve to be opened through a push rod so that the tracer agent in the liquid storage tank can flow to the circular dial through the one-way connection valve. The camera starts to record the running situation of the tracer agent on the circular dial at the same time. The sensor is suitable for measuring the underground water flow speed and flow direction of landslide deformation calculation parameters, can be connected with a clinometer and is convenient to operate, measured data is convenient to process, and the measurement precision is high; the tracer agent squeezed out of a spray nozzle is free of pollution, good in water solubility, equal to water in specific gravity and good in fluidity.

Description

technical field [0001] The invention relates to landslide deformation monitoring in the field of geological engineering, in particular to an intelligent sensor for detecting groundwater flow velocity and direction for landslide monitoring, and is also applicable to engineering applications in other fields that need to monitor groundwater flow velocity and direction. Background technique [0002] Groundwater is an extremely important factor in the deformation, damage and prevention of various landslides. The groundwater flow velocity and flow direction of the landslide are measured to find out the recharge and migration characteristics of the landslide groundwater, so as to provide calculation parameters for the calculation of landslide deformation, and provide a strong basis for the effective prevention and treatment of landslides. The most widely used method for measuring groundwater flow velocity for landslide monitoring is the tracer method. The commonly used methods in ...
