Abstract

The invention belongs to the technical field of detecting equipment of soil tests and in particular relates to an automatic detecting and metering device and an automatic detecting and metering method for rock-soil permeability. The device comprises an automatic compensation water tank and a permeameter communicated with the automatic compensation water tank, wherein the permeameter is connected with at least one measuring cylinder unit; the measuring cylinder unit is provided with a vertically arranged measuring cylinder with uniform inside diameter; floaters capable of floating with the ascending of the liquid level are arranged in the measuring cylinder; a plurality of liquid level position sensors capable of sensing the positions of the floaters are arranged on the wall of the measuring cylinder at intervals; and the liquid level position sensors are connected with a programmed electronic control unit. Through the device and by the method, a variable head permeability test function can be realized; the test process completely satisfies the relative national standard and industrial standard regulation; the device can continuously work for 24 hours to automatically detect the record; the batch detection working efficiency of the permeability test is fully improved; and the labour intensity of workers, the detecting work cost and the influence of detection personnel on the detection result is reduced.

Description

technical field [0001] The invention belongs to the technical field of detection equipment for geotechnical tests, and in particular relates to an automatic detection and measurement device and method for rock and soil permeability characteristics. Background technique [0002] Penetration test is one of the basic testing items of geotechnical testing. The test results are used to estimate the permeability characteristics and changing rules of soil units, and provide accurate and reliable permeability indicators for engineering design and construction. Carry out soil permeability test (permeability coefficient Determination), test and detection equipment is essential. [0003] At present, the test equipment for rock-soil permeability test—permeameter is all manually operated equipment, and the operation items include soil sample loading and unloading, valve opening and closing, data reading, result calculation and report writing, and the whole process of the test requires...
