Description
Technical field
The utility model relates to a kind of indoor in situ simulating test device-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 purpose of this utility model is in order to overcome the deficiency of above-mentioned prior art, to provide a kind of to little, the simple in structure novel soil sample tank prover device of test result influence.
The utility model is that the design to holder model, top board and bottom pressue device improves on the basis of prior art.Therefore the utility model has the holder model of static sounding device, cover, top board and sealing gasket therebetween, tank body, tank body below, displacement transducer and bottom pressue device and intake-discharge pipe and base plate; The air admission hole of tank body periphery and test pressure table; Rubber membrane and sheath that the confined pressure of bearing is arranged in the tank body 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 utility model can also measure the boundary effect of soil sample, a plurality of test holes are arranged at 1/2～2/3 place of existing top board center test hole external radius; Further pressue device is designed to a similar square pressure bag that lifting surface area is bigger.
