Abstract
The present invention relates to an indoor in situ simulation testing device in the exploration of geotechnical engineering, namely a soil sample calibration tank device which comprises a static sounding device, a tank cover, a top plate, a sealing gasket in the top plate, a tank body, a sample holding plate, a displacement sensor, a bottom pressurizing device, a water inlet and outlet pipe, a bottom plate, air inlets in the periphery of the tank body and a pressure gauge for testing, wherein the sample holding plate, the displacement sensor, the bottom pressurizing device, the water inlet and outlet pipe and the bottom plate are arranged below the tank body; a rubber membrane for bearing confining pressure and a sheath are arranged in the tank body. The present invention is characterized in that annular and/or cross-shaped grooves are formed on the sample holding plate and the top plate; considering that the present invention can also measure the border effect of soil samples, a plurality of test holes are formed at 1/2 to 2/3 part of the external radius of the original center test hole in the top plate; the pressurizing device is further designed into a squarish pressure bag with larger stress area. The device of the present invention has the advantages of simple structure, convenient operation and little effect on test results.
Description
Technical field
The present invention relates to a kind of indoor in situ simulating test device one soil sample tank prover device.
Background technology
The effect of soil sample tank prover device is the in-situ stress state of simulate formation soil layer, for the decipher of static sounding in-situ test achievement provides the shop experiment evidence.The use of existing tank prover device proves the of great value instrument of this experimental evidence of a kind of research, but the holder model and the top board of existing tank prover device all are planar structures, cause impeded drainage in process of the test easily, influence test findings; Its bottom pressue device uses three independently pressure bags or use hydraulic piston or hydraulic jacks in addition, causes the inhomogeneous or poorly sealed problem such as close of exerting pressure easily, and complicated operation.
Summary of the invention
The objective of the invention is in order to overcome the deficiency of above-mentioned prior art, provide a kind of little, the simple in structure novel soil sample tank prover device of test result influence.
The present invention is that the design to holder model, top board and bottom pressue device improves on the basis of prior art.Therefore the present invention includes the static sounding device, cover, top board, tank body, holder model and base plate, the static sounding device is arranged at the top center place of cover, the top of tank body is top board, the top of top board is cover, be provided with sealing gasket between top board and the cover, the central authorities of top board are provided with the center test hole, the below of tank body is a base plate, the top of base plate is provided with pressue device and holder model successively, the periphery of tank body is provided with air admission hole and test pressure table, the inside of tank body is provided with rubber membrane and the sheath that bears confined pressure, displacement transducer is connected with the holder model by base plate, the center drilling of holder model taps into drainpipe, it is characterized in that all being provided with on above-mentioned holder model and the top board annular and/or criss-cross groove; Consider that the present invention can also measure the boundary effect of soil sample, be provided with a plurality of test holes in 1/2～2/3 radius that has top board; Further pressue device is designed to a similar square pressure bag that lifting surface area is bigger.
