Description

Technical Field

[0001] This utility model relates to the field of soil testing technology between piles, specifically to a compaction control device for cement-soil compaction pile construction. Background Technology

[0002] In the fields of construction, roads, and municipal engineering, cement-soil compaction piles have become one of the core technologies for reinforcing poor foundations such as loose sand, collapsible loess, and plain fill. The reinforcement principle involves using specialized machinery to drive a cement-soil mixture into the foundation to form piles, which simultaneously exert a radial compaction effect on the surrounding soil layers. Ultimately, the "cement-soil pile body" and the "compacted soil between the piles" together form a composite foundation, thereby improving the foundation's bearing capacity and reducing subsequent settlement.

[0003] The compaction degree of the soil between piles is a key indicator of the synergistic bearing capacity of the composite foundation. If the compaction degree of the soil between piles is insufficient, it will lead to a decrease in the overall bearing capacity of the composite foundation, excessive settlement, and even safety hazards such as cracking and tilting of the superstructure. Therefore, the precise control of the compaction degree of the soil between piles is the core link in the quality control of cement-soil compaction pile construction.

[0004] In current projects, the control of soil compaction between piles mainly relies on "sampling and testing," which involves collecting soil samples between piles to determine the dry density, comparing it with the maximum dry density obtained from indoor compaction tests, and calculating the compaction degree to determine whether it meets the standard.

[0005] In existing technologies, soil sampling between piles is generally achieved using a sleeve sampler. During the sampling process, the sleeve sampler inserts the sleeve into the soil between the piles and removes the soil inside the sleeve. However, the sleeve is usually fixed or bolted to the sampler, making it inconvenient to remove the soil inside the sleeve. This affects the efficiency of soil sampling and testing between piles, and consequently affects the compaction control effect of the soil between piles. Utility Model Content

[0006] This invention proposes a compaction control device for cement-soil compaction pile construction, which solves the problem that the low efficiency of soil sampling between piles in the prior art affects the compaction control effect.

[0007] The technical solution of this utility model is as follows: A compaction degree control device for cement-soil compaction pile construction includes a base plate with a limit opening, a handle, a support frame, a horizontal plate, a sampling sleeve, a lifting mechanism, a rotating mechanism, and a positioning mechanism. The handle is fixedly mounted on the base plate, and a U-shaped support frame is fixedly mounted on the base plate. The horizontal plate is slidably mounted within the support frame, and a support cover is rotatably mounted through the horizontal plate. The sampling sleeve is mounted within the support cover. The lifting mechanism is located between the horizontal plate and the support frame to drive the horizontal plate to move within the support frame. The rotating mechanism is located on the horizontal plate to drive the support cover to rotate. The positioning mechanism is located between the support cover and the sampling sleeve to fix the sampling sleeve within the support cover.

[0008] Preferably, the lifting mechanism includes a first threaded rod and a first motor. The first threaded rod is rotatably disposed between the base plate and the support frame. The first threaded rod passes through the cross plate through a threaded engagement. The first motor is mounted on the support frame. The output end of the first motor is fixedly connected to the first threaded rod. The first motor is a forward and reverse reversible motor.

[0009] Furthermore, the rotating mechanism includes a first cavity, a first gear ring, a first gear, and a first driving mechanism. The first cavity is provided in the horizontal plate, the support cover passes through the first cavity, the first gear ring is fixedly disposed on the outer wall of the support cover, the first gear is rotatably disposed in the first cavity, the first gear meshes with the first gear ring, and the first driving mechanism is disposed on the horizontal plate for driving the first gear to rotate.

[0010] Furthermore, the first driving mechanism includes a first driving port, a second driving port, a driving prism, and a second motor. The first driving port is opened on the horizontal plate, the second driving port is opened on the first gear, the driving prism is rotatably disposed between the base plate and the support frame, the driving prism passes through the first driving port and the second driving port, the driving prism is slidably connected to the side wall of the second driving port, the second motor is mounted on the support frame, and the output end of the second motor is fixedly connected to the driving prism.

[0011] Furthermore, the positioning mechanism includes a positioning groove, a second threaded rod, and a second driving mechanism. The inner top wall of the support cover has two positioning grooves. A positioning block is slidably disposed in the positioning groove. The second threaded rod is rotatably disposed in the positioning groove and passes through the positioning block through a threaded engagement. The second driving mechanism is disposed on the support cover and is used to drive the second threaded rod to rotate. An anti-slip pad is fixedly disposed on the side wall of the positioning block.

[0012] Based on the above scheme, the second drive mechanism includes a second cavity, a second bevel gear, and a handwheel. The second cavity is opened inside the support cover. A first bevel gear is rotatably disposed on the side wall of the second cavity near the second threaded rod. The first bevel gear is fixedly connected to the adjacent second threaded rod. The second bevel gear is rotatably disposed on the side wall of the second cavity and meshes with the first bevel gear. The handwheel is rotatably disposed on the support cover. A drive rod is fixedly disposed between the handwheel and the second bevel gear.

[0013] The working principle and beneficial effects of this utility model are as follows: 1. In this utility model, by setting up a lifting mechanism, the operation of the first motor can drive the first threaded rod to rotate, and at the same time, the threaded engagement between the first threaded rod and the horizontal plate drives the horizontal plate and the support cover to rise and fall, thereby facilitating the insertion of the sampling sleeve into the soil between piles for sampling through the support cover; 2. In this utility model, by setting up a rotating mechanism, the operation of the second motor can drive the driving prism to rotate, and at the same time, the sliding cooperation between the driving prism and the second driving port drives the first gear to rotate, and then the meshing of the first gear and the first gear ring drives the support cover to rotate. Thus, the friction between the positioning block and the sampling sleeve can drive the sampling sleeve to rotate, thereby facilitating the improvement of the sampling efficiency of the sampling sleeve being inserted into the soil between piles. 3. In this utility model, the positioning mechanism allows the second bevel gear to rotate via the rotation of the handwheel. Simultaneously, the meshing of the second bevel gear with the first bevel gear drives the first bevel gear and the second threaded rod to rotate. Furthermore, the threaded engagement between the second threaded rod and the positioning block allows the positioning block to move. This facilitates the fixing and unlocking of the sampling sleeve via the engagement of the positioning block and the sampling sleeve. After sampling, the push rod can be used to push the soil between the piles out of the sampling sleeve, facilitating sampling and testing of the soil between the piles, thereby enabling compaction control through the detection of the soil compaction degree.

Obviously, the described embodiments 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 of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0018] like Figures 1-4 As shown in the figure, this embodiment proposes a compaction control device for cement-soil compaction pile construction, including a base plate 1 with a limit opening 2 on the base plate 1, and also including a handle 3, a support frame 4, a horizontal plate 5, a sampling sleeve 6, a lifting mechanism, a rotating mechanism, and a positioning mechanism. The handle 3 is fixedly installed on the base plate 1, and a U-shaped support frame 4 is fixedly installed on the base plate 1. The horizontal plate 5 is slidably installed in the support frame 4, and a support cover 22 is rotatably installed through the horizontal plate 5. The sampling sleeve 6 is installed in the support cover 22. The lifting mechanism is installed between the horizontal plate 5 and the support frame 4 to drive the horizontal plate 5 to move within the support frame 4. The rotating mechanism is installed on the horizontal plate 5 to drive the support cover 22 to rotate. The positioning mechanism is installed between the support cover 22 and the sampling sleeve 6 to fix the sampling sleeve 6 in the support cover 22. Multiple self-locking casters are installed at the bottom end of the base plate 1.

[0019] Reference Figure 1 and Figure 2 The lifting mechanism includes a first threaded rod 7 and a first motor 8. The first threaded rod 7 is rotatably mounted between the base plate 1 and the support frame 4. The first threaded rod 7 passes through the horizontal plate 5 through a threaded engagement. The first motor 8 is mounted on the support frame 4. The output end of the first motor 8 is fixedly connected to the first threaded rod 7. The first motor 8 is a forward and reverse reversible motor. Specifically, the operation of the first motor 8 can drive the first threaded rod 7 to rotate. At the same time, through the threaded engagement between the first threaded rod 7 and the horizontal plate 5, the horizontal plate 5 and the support cover 22 are driven to rise and fall, thereby facilitating the insertion of the sampling sleeve 6 into the soil between the piles for sampling through the support cover 22.

[0020] Reference Figures 1-3The rotating mechanism includes a first cavity 9, a first gear ring 10, a first gear 11, and a first drive mechanism. The first cavity 9 is formed inside the horizontal plate 5, and a support cover 22 passes through it. The first gear ring 10 is fixedly mounted on the outer wall of the support cover 22. The first gear 11 is rotatably mounted inside the first cavity 9 and meshes with the first gear ring 10. The first drive mechanism is mounted on the horizontal plate 5 and drives the first gear 11 to rotate. The first drive mechanism includes a first drive port 12, a second drive port, a drive prism 13, and a second motor 14. The first drive port 12 is located on the horizontal plate 5, the second drive port is located on the first gear 11, and the drive prism 13 is rotatably mounted between the base plate 1 and the support frame 4. Between the first drive port 12 and the second drive port, the drive prism 13 passes through the first drive port 12 and the second drive port. The drive prism 13 is slidably connected to the side wall of the second drive port. The second motor 14 is mounted on the support frame 4. The output end of the second motor 14 is fixedly connected to the drive prism 13. Specifically, the operation of the second motor 14 can drive the drive prism 13 to rotate. At the same time, the sliding cooperation between the drive prism 13 and the second drive port drives the first gear 11 to rotate. Then, the meshing of the first gear 11 and the first gear ring 10 drives the support cover 22 to rotate. Thus, the friction between the positioning block 16 and the sampling sleeve 6 can drive the sampling sleeve 6 to rotate, thereby facilitating the sampling efficiency of the sampling sleeve 6 inserted into the soil between the piles.

[0021] Reference Figure 3 and Figure 4The positioning mechanism includes a positioning groove 15, a second threaded rod 17, and a second drive mechanism. Two positioning grooves 15 are formed on the inner top wall of the support cover 22. A positioning block 16 is slidably disposed within each positioning groove 15. The second threaded rod 17 is rotatably disposed within the positioning groove 15 and passes through the positioning block 16 via a threaded engagement. The second drive mechanism is mounted on the support cover 22 and is used to drive the second threaded rod 17 to rotate. An anti-slip pad is fixedly disposed on the side wall of the positioning block 16. The second drive mechanism includes a second cavity 18, a second bevel gear 20, and a handwheel 21. The second cavity 18 is formed within the support cover 22. A first bevel gear 19 is rotatably disposed on the side wall of the second cavity 18 near the second threaded rod 17. The first bevel gear 19 is fixedly connected to the adjacent second threaded rod 17. The second bevel gear 20 is rotatably disposed on the side wall of the second cavity 18. The first bevel gear 19 meshes with the second bevel gear 20. The handwheel 21 is rotatably mounted on the support cover 22. A drive rod is fixedly installed between the handwheel 21 and the second bevel gear 20. Specifically, after the sampling sleeve 6 is removed from the soil between the piles, the rotation of the handwheel 21 can drive the second bevel gear 20 to rotate. At the same time, the meshing of the second bevel gear 20 with the first bevel gear 19 drives the first bevel gear 19 and the second threaded rod 17 to rotate. Then, the threaded engagement between the second threaded rod 17 and the positioning block 16 can drive the positioning block 16 to move. This facilitates the unlocking of the sampling sleeve 6 through the engagement of the positioning block 16 and the sampling sleeve 6. After sampling, the push rod can be used to push the soil between the piles out of the sampling sleeve 6, which facilitates the sampling and testing of the soil between the piles, thereby realizing the detection of the compaction degree of the soil between the piles and achieving compaction degree control.

[0022] In this embodiment, during use, after the base plate 1 is moved above the soil between piles, the operator controls the first motor 8 and the second motor 14 to operate. The operation of the first motor 8 can drive the first threaded rod 7 to rotate. At the same time, through the threaded engagement between the first threaded rod 7 and the horizontal plate 5, the horizontal plate 5 and the support cover 22 are raised and lowered, thus facilitating the insertion of the sampling sleeve 6 into the soil between piles for sampling via the support cover 22. Simultaneously, the operation of the second motor 14 can drive the drive prism 13 to rotate. At the same time, through the sliding engagement between the drive prism 13 and the second drive port, the first gear 11 is driven to rotate. Furthermore, through the meshing of the first gear 11 and the first gear ring 10, the support cover 22 is driven to rotate. Thus, the friction between the positioning block 16 and the sampling sleeve 6 can drive the sampling sleeve 6 to rotate, thereby facilitating the... To improve the sampling efficiency of the sampling sleeve 6 inserted into the soil between piles, the operator then controls the first motor 8 to reverse and reset the sampling sleeve 6. The operator then rotates the handwheel 21, which drives the second bevel gear 20 to rotate. Simultaneously, the meshing of the second bevel gear 20 with the first bevel gear 19 drives the first bevel gear 19 and the second threaded rod 17 to rotate. This allows the second threaded rod 17 to move the positioning block 16 through its threaded engagement with the positioning block 16, facilitating the unlocking of the sampling sleeve 6. After sampling, a push rod can be used to push the soil between piles out of the sampling sleeve 6, facilitating sampling and testing of the soil between piles, and ultimately enabling compaction control through compaction degree testing.

[0023] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
