The invention discloses a pressure box vertical placement device for testing rock and soil mechanical properties in rock and soil experiments, and belongs to the technical field of rock and soil engineering tests. The pressure box vertical placement device comprises a hollow pull rod, and the bottom end of the pull rod is in threaded connection with a fixing mechanism used for fixing a pressure soil box; and supporting mechanisms used for supporting and protecting the pressure soil box are arranged at the bottom end of the fixing mechanism and the side, away from the rock soil to be tested, of the fixing mechanism, and the top end of the pull rod is detachably connected with a soil drilling mechanism used for facilitating placement of the pressure soil box. According to the pressure box vertical placement device, the distance between the supporting plate and the bottom plate can be adjusted through cooperation of the connecting column on the fixing mechanism, the first mounting cylinder and the second mounting cylinder, so that pressure boxes of different sizes can be fixed and prevented from moving, meanwhile, assemblies in the side plates are protected through the arranged telescopic plate and the protection mechanism, and corrosion is prevented.
Description
technical field [0001] The invention belongs to the technical field of geotechnical engineering testing, and in particular relates to a pressure cell vertical placement device used for testing geotechnical properties in geotechnical experiments. Background technique [0002] The pressure cell is used to measure the internal stress of the medium in geotechnical engineering, as well as the instrument for measuring the contact stress between the surrounding rock and the supporting structure, and between the shotcrete and the cast-in-place concrete. During the construction process, in order to measure the vertical pressure, the pressure cell needs to be placed in the rock and soil, but in the prior art, most of the pressure cells are directly placed in the rock and soil, it is difficult to ensure whether the pressure cell is placed horizontally in the rock and soil, which will cause measurement errors and affect the measurement As a result, when the pressure cell is placed, if t...
