Description

Technical Field

[0001] This utility model belongs to the field of geotechnical testing technology, and more specifically, it relates to a pressure device for geotechnical consolidation testing. Background Technology

[0002] A consolidation apparatus is an industrial instrument used to determine the compressibility of soil under different loads and lateral confinement conditions. It can perform normal slow consolidation tests and rapid consolidation tests, determining the pre-consolidation pressure and consolidation coefficient. Conventional consolidation tests use a compression testing apparatus to measure the relationship between soil deformation and time-pressure under lateral confinement conditions. Combined with other test indicators, the soil's compressibility coefficient and compression modulus are calculated to determine the soil's compressibility level. By measuring the deformation of soil samples under various levels of vertical loads, the corresponding void ratio under each load is calculated to determine the soil's compressibility coefficient and compression modulus. In existing geotechnical consolidation testing, the device used to apply pressure to the test specimen is a pressurizing device. This device typically uses a piston rod and a pressure plate for pressurization, and the pressure application position is fixed, meaning the pressure application position cannot be adjusted. In geotechnical consolidation tests, when multiple sets of test specimens are involved and all require pressure application, the usual procedure is to manually handle the specimens, place them sequentially at the pressure application points of the pressurizing device, apply pressure, and then remove them. This process is repeated for each set of specimens. This method requires a high level of experimental skill from the personnel, increases workload, and poses certain safety hazards.

[0003] Therefore, it is necessary to design a pressurizing device that can sequentially apply pressure to multiple groups of test pieces at different locations, so as to achieve automatic pressurization of multiple groups of test pieces at different locations to meet the experimental requirements of multiple groups of test pieces.

The pressure component 4, with the help of the sliding component 2 and the telescopic beam 3, can adjust the pressure position of the test pieces 7, and the pressure applied by the pressure component 4 can be adjusted.

[0034] This utility model provides a pressurization device for geotechnical consolidation experiments. Compared with the prior art, the operating platform 1 can accommodate multiple sets of test pieces 7, which is convenient for pressurization operations. Through the cooperation and adjustment of the sliding component 2 and the telescopic beam 3, pressurization can be applied to test pieces 7 at different positions.

Specifically, the push rod 11 is electrically connected to the control panel 9 and its operation is controlled by the control panel 9.

[0040] In some embodiments, please refer to Figures 1 to 3The sliding assembly 2 includes a horizontal plate 21 and a vertical plate 22. Multiple sliders 23 are provided at the bottom of the horizontal plate 21, and these sliders 23 are slidably connected to two slide rails 5. The upper end of the horizontal plate 21 forms a placement area 24 suitable for placing the workpiece 7 to be inspected.

The vertical plate 22 is located near the side of the horizontal plate 21. To reduce its weight, the vertical plate 22 is designed as a frame structure without affecting the placement of the slide groove 6.

[0041] To ensure that multiple sets of test pieces 7 are stably placed in the placement area 24, in some embodiments, please refer to... Figure 3 The placement area 24 is provided with multiple ring-shaped clamping assemblies 25, which are suitable for clamping and fixing the workpiece 7 to be inspected.

[0043] In some embodiments, please refer to Figures 4 to 5 The pressurizing assembly 4 includes a piston rod 41 and a pressure plate 42. The piston rod 41 is vertically arranged, with its upper end connected to the cantilever end of the telescopic beam 3. The pressure plate 42 is connected to the lower end of the piston rod 41 and is suitable for applying pressure to the workpiece 7 under inspection. The pressure plate 42 is circular or rectangular. In this embodiment, the piston rod 41 is a general concept or description. The piston rod 41 can be telescopically adjustable. For example, a piston rod 41 from the prior art can be selected, or a cylinder, electric cylinder, or other products from the prior art can be selected. It is electrically connected to the control panel 9, and the length of the piston rod 41 can be adjusted by control, thereby realizing the pressurization operation of the workpiece 7 under inspection. The diameter of the pressure plate 42 is greater than or equal to the outer diameter of the piston rod 41.

[0044] In some embodiments, please refer to Figure 5When the pressure plate 42 is circular, a collar 43 is fitted around its outer circumference. The collar 43 is suitable for pressing down on the workpiece 7 simultaneously with the pressure plate 42, thereby increasing the pressing area of ​​the workpiece 7. When the pressing area of ​​the pressure plate 42 on the workpiece 7 is small, the collar 43 can be fitted around the outer circumference of the pressure plate 42, fixing the collar 43 to the pressure plate 42. This allows the pressure plate 42 and the collar 43 to press down on the workpiece 7 simultaneously, increasing the pressing area and improving the efficiency of the pressing operation. Please refer to [link to relevant documentation]. Figure 5 If setting one nested ring 43 is not enough to meet the requirements, then two nested rings 43 can be set to meet the requirements.
