Cohesive soil plasticity field judging instrument and field judging method thereof
The invention relates to the field of rock and soil exploration, in particular to a cohesive soil plasticity field judging instrument and a field judging method thereof. The cohesive soil plasticity field judging instrument and the field judging method thereof are characterized in that the judging instrument comprises a protection cylinder, an air bag is arranged in a cavity of the protection cylinder, the top of the air bag is connected with an inflation device communicated with the interior of the air bag, a probe is arranged at the bottom of the air bag, the probe is connected and fixed to the outer surface of the bottom of the air bag, an air outlet hole is formed in the air bag, the air outlet hole is communicated with one end of a U-shaped pipe, the other end of the U-shaped pipe is provided with a sealing cap, a plurality of reference lines representing the cohesive soil plasticity are divided on the surface of the outer wall of the end, provided with the sealing cap, of the U-shaped pipe, and a certain solution is poured in the U-shaped pipe. The cohesive soil plasticity field judging instrument and the field judging method thereof have the advantages that the plasticity of cohesive soil can be rapidly and correctly judged, and the cohesive soil plasticity field judging instrument is simple in structure, high in operability, complete in function and the like.
