Description

Technical Field

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

[0002] The process by which soil consolidates under external loads, as pore water pressure gradually dissipates, void ratio decreases, soil volume decreases, soil particles rearrange, and effective stress gradually increases, is called soil consolidation. Soil consolidation is crucial in civil engineering fields such as foundation engineering and hydraulic engineering, affecting the stability and long-term performance of buildings and structures. Consolidation theory is an important theory in the study of soil consolidation; it predicts the consolidation behavior of soil under different conditions through consolidation tests and theoretical analysis. Consolidation tests measure the correlation between pressure, compression deformation, and corresponding time when a soil sample is subjected to graded pressures under fully confined conditions. Consolidation tests can be classified into conventional consolidation tests, rapid consolidation tests, high-pressure consolidation tests, and continuous-load consolidation tests.

[0003] Existing consolidation testing equipment uses horizontally placed ring samplers and applies pressure vertically. A single pressure source can only be applied to one sample at a time. Therefore, this testing method can only test a single sample at a time. Furthermore, this pressure application method requires placing a pressure-applying structure above the sample; the weight of this structure can cause deformation of the sample, interfering with the accuracy of the test.

[0004] As can be seen from the above, the existing equipment has problems with low efficiency in soil consolidation tests and the results are prone to errors. Utility Model Content

[0005] The main purpose of this invention is to provide a horizontal pressure consolidation apparatus to solve the problems of low efficiency and error in soil consolidation tests in existing equipment.

[0006] To achieve the above objectives, this utility model provides a horizontal pressure consolidation apparatus, comprising: a worktable; multiple soil sample box assemblies arranged sequentially on the worktable in a horizontal direction, the multiple soil sample box assemblies constituting a test unit; a pushing mechanism; and an adjusting mechanism, both of which are disposed on the worktable and located at both ends of the arrangement direction of the multiple soil sample box assemblies, so that the adjusting mechanism and the pushing mechanism can be used to apply loads to the test unit.

[0007] Furthermore, the soil sample box assembly includes: a soil sample box body; a pressure plate, which is movably disposed on the side of the soil sample box body and together with the soil sample box body forms a space for containing soil samples. The pressure plate abuts against another soil sample box assembly or directly abuts against the pushing mechanism so that force is transmitted between two adjacent soil sample box assemblies through the pressure plate.

[0008] Furthermore, the top of the soil sample box body is provided with an opening, through which the pressure plate extends into the soil sample box body, and the soil sample box assembly also includes a guide member, which is provided at the opening to fix the pressure plate installed in the soil sample box body.

[0009] Furthermore, the soil sample box assembly also includes a displacement sensor, with its two ends connected to the soil sample box body and the pressure plate, respectively, to detect the movement distance of the pressure plate.

[0010] Furthermore, the soil sample box assembly also includes a connecting bracket, through which the displacement sensor is connected to the pressure plate.

[0011] Furthermore, a sample inlet is provided at the top of the soil sample box body, and the soil sample box assembly also includes a ring cutter, which is detachably installed in the soil sample box body through the sample inlet.

[0012] Furthermore, the soil sample box assembly also includes two permeable elements. The two permeable elements are spaced apart along the arrangement direction of the multiple soil sample box assemblies and located on both sides of the soil sample, and one of the permeable elements is in contact with the pressure transmission plate.

[0013] Furthermore, the horizontal pressure consolidation apparatus also includes a slide rail, which extends along the arrangement direction of multiple soil sample box assemblies, and the bottom of the soil sample box assembly is slidably connected to the slide rail.

[0014] Furthermore, the workbench includes: a base plate; a surrounding structure, the surrounding structure being erected on the base plate and together with the base plate forming a placement area for accommodating the soil sample box assembly, the length of the adjustment mechanism extending into the placement area being adjustable, and at least a portion of the pushing mechanism extending into the placement area to push the soil sample box assembly.

[0015] Furthermore, the pushing mechanism includes: a driving body, which is disposed on the base plate and located outside the placement area; a pushing rod, which is drivenly connected to the body, and at least a portion of the pushing rod extends into the placement area and abuts against the pressure transmission plate; and a pressure sensor, which is disposed on the pushing rod and located in the placement area accommodating the soil sample box assembly, for detecting the pressure applied by the pushing rod.

[0016] The horizontal pressure consolidation apparatus of this invention includes a worktable, soil sample box assemblies, a pushing mechanism, and an adjusting mechanism. Multiple soil sample box assemblies are arranged sequentially on the worktable in a horizontal direction, forming a test unit. The adjusting mechanism and the pushing mechanism are both located on the worktable at opposite ends of the arrangement of the soil sample box assemblies, allowing them to apply pressure to the test unit. By arranging the multiple soil sample box assemblies horizontally, with the adjusting mechanism and pushing mechanism at opposite ends of the test unit, the pushing mechanism applies horizontal pressure to one end of the test unit, thus simultaneously subjecting multiple soil sample box assemblies to pressure. During this process, the soil sample placed inside the soil sample box assembly deforms under horizontal pressure. This invention enables simultaneous testing of multiple soil samples under a single pressure source. Furthermore, since the soil sample is only subjected to horizontal pressure, deformation due to the weight of the soil sample box assembly avoids interference with the test results, thereby improving the accuracy and efficiency of the test results. This solves the problems of low efficiency and error-prone results in existing soil consolidation tests. Attached Figure Description

[0026] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0027] To address the issues of low efficiency and error-prone results in existing soil consolidation tests, this invention provides a horizontal pressure consolidation apparatus.

[0028] like Figures 1 to 3 As shown, the horizontal pressure consolidation apparatus includes a worktable 10, soil sample box assemblies 20, a pushing mechanism 30, and an adjusting mechanism 40. Multiple soil sample box assemblies 20 are arranged sequentially along a horizontal direction on the worktable 10, forming a test unit. The adjusting mechanism 40 and the pushing mechanism 30 are both located on the worktable 10 at opposite ends of the arrangement direction of the multiple soil sample box assemblies 20, allowing them to apply pressure to the test unit.

[0029] By arranging multiple soil sample box assemblies 20 horizontally, with the adjustment mechanism 40 and the pushing mechanism 30 located at opposite ends of the test unit, the pushing mechanism 30 applies horizontal pressure to one end of the test unit, thereby simultaneously subjecting multiple soil sample box assemblies 20 to pressure. During this process, the soil sample 100 placed inside the soil sample box assembly 20 deforms under horizontal pressure. By applying the technical solution of this application, multiple soil samples 100 can be tested simultaneously. Furthermore, since the soil sample 100 is only subjected to horizontal pressure, the deformation of the soil sample 100 due to the weight of the soil sample box assembly 20 is avoided from interfering with the test results, thus improving the accuracy and efficiency of the test results.

[0030] like Figures 1 to 3As shown, the soil sample box assembly 20 includes a soil sample box body 21 and a pressure transmission plate 22. The pressure transmission plate 22 is movably disposed on the side of the soil sample box body 21 and together with the soil sample box body 21 forms a space for accommodating the soil sample 100. The pressure transmission plate 22 abuts against another soil sample box assembly 20 or directly abuts against the pushing mechanism 30, so that force is transmitted between two adjacent soil sample box assemblies 20 through the pressure transmission plate 22.

[0031] Specifically, the size of the permeable element 27 connected to the pressure transmission plate 22 is adapted to the inner diameter of the soil sample 100 and slightly smaller than the inner diameter of the ring cutter 26, so that the permeable element 27 connected to the pressure transmission plate 22 can extend into the ring cutter 26 to compress the soil sample 100. Multiple soil sample box assemblies 20 are arranged along the same straight line and abut against each other. The portion of the pressure transmission plate 22 extending into the soil sample box body 21 forms a receiving space with the soil sample box body 21, while the other portion abuts against an adjacent soil sample box body 21 or is connected to the pushing mechanism 30. Optionally, the pressure transmission plate 22 includes a plate body and a protruding structure disposed on the plate body. One side of the plate body forms a receiving space between it and the soil sample box body 21, and the protruding structure is disposed on the other side of the plate body, abutting against the bottom of the soil sample box body 21 of an adjacent soil sample box assembly 20. This structure ensures continuous pressure transmission among multiple soil sample box assemblies 20 and is suitable for scenarios where multiple soil samples 100 are simultaneously pressurized.

[0032] In this embodiment, multiple soil sample box components 20 are connected end to end in a straight line.

[0033] In another embodiment of this application (not shown), two adjacent soil sample box assemblies 20 are connected head-to-head or tail-to-tail, meaning that the orientation of the multiple soil sample box assemblies 20 is not the same.

[0034] like Figures 1 to 2 As shown, the top of the soil sample box body 21 is provided with an opening, and the pressure plate 22 extends into the soil sample box body 21 through the opening. The soil sample box assembly 20 also includes a guide 23, which is provided at the opening to fix the pressure plate 22 installed in the soil sample box body 21 and prevent it from falling out accidentally.

[0035] Specifically, the opening is located on the side of the soil sample box body 21. When the pressure plate 22 extends into the opening, the guide 23 limits the pressure plate 22, thereby keeping it vertical and preventing it from tipping over due to its own weight, which could cause the soil sample 100 to detach from the soil sample box body 21, or causing the pressure plate 22 to tilt, resulting in uneven stress on the soil sample 100 and test failure. At the same time, the guide 23 increases the safety of the instrument, preventing accidents during the test, and greatly reduces the friction between the pressure plate 22 and the guide 23. This makes it suitable for laboratory environments where soil samples 100 need to be frequently changed for testing, ensuring the smooth progress of the test.

[0036] like Figure 1 and 3 As shown, the soil sample box assembly 20 also includes a displacement sensor 24, with its two ends connected to the soil sample box body 21 and the pressure plate 22, respectively, to detect the moving distance of the pressure plate 22.

[0037] Specifically, the displacement sensor 24 detects the movement distance of the pressure plate 22 in real time. When the pressure on the soil sample 100 from the pushing mechanism 30 changes, the displacement sensor 24 can effectively detect the changes in the soil sample 100 because the soil sample 100 is small and the deformation is not easy to observe. Optionally, the displacement sensor 24 can be connected to a display to convert the difficult-to-observe compression deformation of the soil sample 100 into easily observable digital changes, which can help the test personnel confirm the progress of the test.

[0038] like Figures 1 to 2 As shown, the soil sample box assembly 20 also includes a connecting bracket 25, through which the displacement sensor 24 is connected to the pressure plate 22.

[0039] Specifically, one end of the connecting bracket 25 is connected to the pressure transmission plate 22, and the other end is connected to the displacement sensor 24. Optionally, both ends of the connecting bracket 25 can be detachably connected to the pressure transmission plate 22 and the displacement sensor 24 respectively. The connecting bracket 25 can be threaded or snap-fitted to the pressure transmission plate 22 and the displacement sensor 24. Alternatively, the connecting bracket 25 can be integrally formed with the pressure transmission plate 22, and the connecting bracket 25 can be threaded to the displacement sensor 24.

[0040] In this embodiment, the guide member 23 is an open linear bearing. The inner ring of the guide member 23 is connected to the pressure transmission plate 22, and the outer ring is disposed inside the soil sample box body 21. The opening avoids the connecting bracket 25. Of course, the guide member 23 can also be other structural components, as long as they satisfy the limiting and guiding functions of the pressure transmission plate 22.

[0041] like Figure 1 As shown, the soil sample box assembly 20 also includes a permeable element 27. There are two permeable elements 27. The two permeable elements 27 are arranged at intervals along the arrangement direction of the multiple soil sample box assemblies 20 and are located on both sides of the soil sample 100. One of the permeable elements 27 is in contact with the pressure transmission plate 22.

[0042] Specifically, the permeable component 27 is a permeable stone that is compatible with the soil sample 100. The permeable stone is set on both sides of the soil sample 100 to ensure that water is discharged during the pressurization process. At the same time, the setting of the permeable component 27 also ensures the uniformity of the stress on the soil sample 100 to a certain extent.

[0043] like Figure 1As shown, the top of the soil sample box body 21 is provided with a sample inlet 211, and the soil sample box assembly 20 also includes a ring cutter 26, which is detachably installed inside the soil sample box body 21 through the sample inlet 211.

[0044] Specifically, after the ring cutter 26 completes sampling in the designated area, it is vertically placed into the soil sample box body 21 through the sample inlet 211. Keeping the ring cutter 26 vertical ensures that the soil sample 100 inside the ring cutter 26 is only subjected to horizontal pressure, thereby avoiding compression deformation of the soil sample 100 due to the weight of the pressure plate 22. At the same time, placing the ring cutter 26 into the soil sample box assembly 20 facilitates the filling and replacement of the soil sample 100.

[0045] In this embodiment, the cross-sections of the pressure plate 22 and the permeable element 27 are circular, and the size of the permeable element 27 connected to the pressure plate 22 is adapted to the inner diameter of the soil sample 100, which is slightly smaller than the inner diameter of the ring cutter 26, so that the permeable element 27 connected to the pressure plate 22 can extend into the ring cutter 26.

[0046] like Figures 1 to 3 As shown, the horizontal pressure consolidation apparatus also includes a slide rail 28, which extends along the arrangement direction of the multiple soil sample box assemblies 20, and the bottom of the soil sample box assembly 20 is slidably connected to the slide rail 28.

[0047] Specifically, the slide rail 28 is arranged along the axial direction of the soil sample box body 21 on the worktable 10. The arrangement of multiple soil sample box bodies 21 on the slide rail 28 ensures that the deformation direction of multiple soil sample box components 20 is consistent, and the arrangement of the slide rail 28 can reduce the friction between the soil sample box components 20 and the worktable 10. At the same time, the design of the slide rail 28 makes the movement of the soil sample box components 20 more stable, which facilitates the observation of soil sample 100 deformation.

[0048] In this embodiment, the soil sample box assembly 20 also includes a slider 29, which is disposed at the bottom of the soil sample box body 21 and is detachably connected to the soil sample box body 21. The slider 29 cooperates with the slide rail 28 to realize the sliding of the soil sample box body 21 on the slide rail 28.

[0049] In another embodiment of this application (not shown), the bottom of the soil sample box body 21 is provided with a structure that is adapted to the slide rail 28, and the soil sample box body 21 is directly mounted on the slide rail 28.

[0050] like Figure 1 As shown, the workbench 10 includes a base plate 11 and a surrounding structure 12. The surrounding structure 12 is erected on the base plate 11 and together with the base plate 11 forms a placement area for accommodating the soil sample box assembly 20. The length of the adjustment mechanism 40 extending into the placement area is adjustable. At least a portion of the pushing mechanism 30 extends into the placement area through the sealing member 50 to push the soil sample box assembly 20.

[0051] Specifically, the slide rail 28 is set on the base plate 11, the surrounding plate structure 12 is set on the base plate 11, and the surrounding plate structure 12 forms a frame structure with a rectangular cross section. One end of the adjustment mechanism 40 is threadedly connected to the surrounding plate structure 12, and the other end abuts against the soil sample box body 21. By adjusting the depth of the adjustment mechanism 40 extending into the surrounding plate structure 12, the multiple soil sample box components 20 can be made to abut at both ends, and at the same time, it is convenient to adjust the depth of the pressure plate 22 extending into the soil sample box body 21.

[0052] like Figure 1 As shown, the pushing mechanism 30 includes a drive body 31, a pushing rod 32, and a pressure sensor 33. The drive body 31 is mounted on the base plate 11 and located outside the placement area. The pushing rod 32 is connected to the drive body 31, and at least a portion of the pushing rod 32 extends into the placement area through a seal 50 and abuts against the soil sample box assembly 20. The pressure sensor 33 is mounted on the pushing rod 32 and located within the placement area accommodating the soil sample box assembly 20, for detecting the pressure applied by the pushing rod 32.

[0053] Specifically, the drive unit 31 can be any one of an electric servo pressurization device, a pneumatic pressurization device, or a hydraulic pressurization device. When the drive unit 31 is an electric servo pressurization device, it includes a control unit, a servo motor driver, a servo motor, a reducer, and a linear ball pusher. The control unit provides control signals to the servo motor driver to control the servo motor to operate, and increases the torque through the reducer to drive the linear ball pusher to move.

[0054] In this embodiment, there is one pushing mechanism 30, which is located on one side of the enclosure structure 12. The driving main body 31 is connected to the pressure plate 22 of the soil sample box assembly 20 near the pushing mechanism 30 through the pushing rod 32. Alternatively, the driving main body 31 can be connected to the soil sample box body 21 of the soil sample box assembly 20 near the pushing mechanism 30 through the pushing rod 32.

[0055] In another embodiment of this application (not shown), there are two pushing mechanisms 30, which are located on both sides of the soil sample box assembly 20 and are respectively connected to the soil sample box body 21 and the pressure plate 22 of the soil sample box assembly 20.

[0056] In this embodiment, the enclosure structure 12 is provided with a through hole, the push rod 32 extends into the through hole, and abuts against the pressure transmission plate 22 via the pressure sensor 33. The accurate measurement capability of the pressure sensor 33 ensures the controllability of the pressurization process.

[0057] like Figure 1As shown, the horizontal pressure consolidation apparatus also includes a sealing element 50, which is sleeved on the push rod 32. The sealing element 50 seals the gap between the push rod 32 and the through hole. When water is injected between the surrounding plate structure 12 and the bottom plate 11, the soil sample 100 is submerged in water. This prevents water from flowing out of the through hole during the immersion test. After the immersion test is completed, the injected water is discharged through the drainage control element 13.

[0058] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: By setting the horizontal pressure consolidation apparatus including a workbench 10, soil sample box assemblies 20, a pushing mechanism 30, and an adjusting mechanism 40, multiple soil sample box assemblies 20 are arranged sequentially on the workbench 10 in a horizontal direction, and multiple soil sample box assemblies 20 constitute a test unit. The adjusting mechanism 40 and the pushing mechanism 30 are both set on the workbench 10 and located at both ends of the arrangement direction of the multiple soil sample box assemblies 20, so that the adjusting mechanism 40 and the pushing mechanism 30 are used to pressurize the test unit. By arranging multiple soil sample box assemblies 20 in a horizontal direction, the adjusting mechanism 40 and the pushing mechanism 30 are used to pressurize the test unit. The joint mechanism 40 and the pushing mechanism 30 are located at both ends of the test unit. The pushing mechanism 30 applies horizontal pressure to one end of the test unit, thereby enabling multiple soil sample box assemblies 20 to be subjected to pressure simultaneously. During this process, the soil sample 100 placed inside the soil sample box assembly 20 is deformed by the horizontal pressure. By applying the technical solution of this application, multiple soil samples 100 can be tested simultaneously. At the same time, since the soil sample 100 is only subjected to horizontal pressure, the deformation of the soil sample 100 due to the self-weight of the soil sample box assembly 20 is avoided, which would interfere with the test results, thereby improving the accuracy and efficiency of the test results.
