Abstract

The invention discloses a device for continuously obtaining drill hole in-situ water samples and a water taking method. The device comprises an air pressure control system, a pipeline transportation system, a lifting control system, a water inlet control system and a plug isolation system, wherein the air pressure control system is mainly used for providing a pressure difference for the water intake control system. The pipeline transportation system is mainly used for transmitting an air pressure and conveying the water samples. The lifting control system is mainly used for dropping and lifting a water taking device. The plug isolation system is mainly used for isolating a water taking test section. The water inlet control system is mainly used for controlling opening and closing of a water inlet valve according to the pressure difference. The device for continuously obtaining the drill hole in-situ water samples, provided by the invention, can continuously obtain the samples at different depths below the drill hole underground water level under the condition of one dropping and one lifting of the water taking device, and has the advantages of being low in manufacturing cost, simple in structure, easy to operate, and the like.

Description

technical field [0001] The invention belongs to the field of hydrogeology, and in particular relates to a device and method for continuously obtaining in-situ water samples in boreholes. The device can be used to continuously obtain in-situ water samples at different depths below the groundwater surface of boreholes. Background technique [0002] When analyzing the hydrogeological conditions in the study area, it is sometimes necessary to obtain in-situ water samples from different depths of boreholes in the study area for hydrochemical and isotope analysis. In the past, the borehole water intake device needed to repeat the operation of lowering and lifting the water intake device in order to obtain water samples at different depths of the borehole. In addition, in the past, the water intake device usually obtained the mixed water in the borehole. There is still no simple and efficient device for how to avoid repeated lifting and unloading of the water intake device and con...
