The invention discloses an automatic double-ring water penetration testing instrument. The automatic double-ring water penetration testing instrument comprises an upper water tank, a middle double-ring device and a lower double-ring base. The lower double-ring base comprises an inner-ring base body and an outer-ring base body, the middle double-ring device comprises an outer ring and an inner ring, an inner ring water outlet device and an inner ring water level monitoring device are arranged on the inner side of the inner ring, and an outer ring water outlet device and an outer ring water level monitoring device are arranged between the inner ring and the outer ring. The upper water tank comprises a tank body, an inner ring water flow control device and an outer ring water flow control device are arranged at the bottom of the tank body, and a data recording display and control device is arranged on the tank body and connected with the inner ring water level monitoring device, the outer ring water level monitoring device, the inner ring water flow control device and the outer ring water flow control device. In the testing process, the automatic double-ring water penetration testing instrument does not need to be manually controlled, water supply and reading are automatically completed, manual errors are reduced, and the automatic double-ring water penetration testing instrument has the advantages of being easy and convenient to operate and high in precision.
Description
technical field [0001] The invention relates to a water seepage test instrument for hydrogeological field investigation of a vadose zone, in particular to a double-ring automatic water seepage test instrument. Background technique [0002] The water seepage test method can be divided into constant water head seepage test and constant flow water seepage test according to the constant water head and constant flow rate of the water supply in the test process. The traditional field water seepage test instrument is relatively simple. Generally, the single ring body placed in the test pit at the bottom is used, and the scale is marked on the single ring body. The water level in the single ring body is controlled by adding water, and the amount of water added within a certain period of time is recorded. Calculate the hydraulic conductivity, or calculate the hydraulic conductivity by recording the drop in water level over a period of time. During the test process, water injection a...
