Problems solved by technology

The use of the existing calibration tank device proves to be a valuable tool for researching this kind of test evidence, but the supporting sample plate and the top plate of the existing calibration tank device are all plane structures, which may easily cause poor drainage during the test. Affect the test results; in addition, the bottom pressurization device uses three independent pressure bags or uses hydraulic pistons or hydraulic jacks, which is likely to cause problems such as uneven pressure or poor sealing, and the operation is complicated

Embodiment Construction

[0010] like figure 1 As shown, the present invention has a static penetration device 15, a tank cover 11, a top plate 10, a gasket 12 therebetween, a tank body 8, a sample plate 4 under the tank body, a displacement sensor 14, and a bottom pressure device 3 and an inlet The drain pipe 19 and the bottom plate 1; the air inlet 6 and the test pressure gauge 13 around the tank body 8; It is characterized in that the above-mentioned supporting plate 4 and top plate 10 are provided with annular and / or cross-shaped grooves 16; such as image 3 , Figure 4 . As another embodiment, a plurality of test holes are opened at 1 / 2 to 2 / 3 of the outer radius of the central test hole of the existing top plate, such as Figure 4 There are three test holes 18, and the other two holes can be used as drainage channels when one of the holes is tested during the test. The above-mentioned vertical pressure device 3 is a square-like rubber pressure bag with a larger force-bearing area. like fig...

Abstract

The invention relates to indoor in situ simulation testing device-soil sample calibration pot device for rock and soil engineering. It includes a static contacting device, pot cover, top board and a sealing cushion, pot, sample board under the pot, shift sensor and the bottom pressing device, and water pipe and bottom board; the air inlet around the pot and the pressure meter; there has rubber film and protection cover bearing around pressure in the pot, the character is that the sample board and the top board are arranged with a ring and / or cross concave slots; considering that, the invention also can measure the criteria effect of the soil sample to be measured, there has several testing apertures on the 1 / 2-2 / 3 position of the external radius; the pressing device is designed into a pressure bag square type whose stress area is larger.

Description

technical field [0001] The invention relates to an indoor in-situ simulation test device in geotechnical engineering investigation, a soil sample calibration tank device. Background technique [0002] The function of the soil sample calibration tank device is to simulate the in-situ stress state of the underground soil layer, and to provide laboratory test evidence for the interpretation of the in-situ test results of static penetration. The use of the existing calibration tank device has proved to be a valuable tool to study this kind of test evidence, but the support plate and the top plate of the existing calibration tank device are all flat structures, which are easy to cause poor drainage during the test process. Affect the test results; in addition, the bottom pressure device uses three independent pressure bags or uses hydraulic pistons or hydraulic jacks, which may easily cause problems such as uneven pressure application or poor sealing, and the operation is complic...
