[0002] The foundation is the portion of soil or rock that directly bears the load of a building. It is located below the foundation and is an important guarantee for the stability and safety of the building.

[0003] Foundation backfill compaction equipment is a type of mechanical equipment used to compact foundation backfill soil. These devices generate strong impact or vibration forces to compact loose soil particles, thereby improving the bearing capacity and stability of the foundation.

[0004] However, the existing foundation backfill compaction devices have a large compaction surface area for applying impact or vibration to the foundation backfill, making it difficult to compact foundation backfill located in a narrow space. This results in poor flexibility of the foundation backfill compaction device. Therefore, it does not meet the current requirements. To address this, we propose a foundation backfill compaction device. Utility Model Content

[0005] The purpose of this utility model is to provide a foundation backfill soil compaction device to solve the problems mentioned in the background art, such as the large area of ​​the compaction surface used to apply impact or vibration force to the foundation backfill soil, making it difficult to compact the foundation backfill soil located in a narrow space, and the poor flexibility of this foundation backfill soil compaction device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a foundation backfill soil compaction device, comprising a cylindrical shell of the compaction device, a first compaction plate fixed to the lower end face of the cylindrical shell of the compaction device, a second compaction plate above the first compaction plate, a third compaction plate above the second compaction plate, a fourth compaction plate above the third compaction plate, and a fifth compaction plate above the fourth compaction plate. The inner wall shapes of the fifth, fourth, third, and second compaction plates correspond to the outer surface shapes of the fourth, third, second, and first compaction plates, respectively, and the fifth, fourth, third, and second compaction plates are respectively larger than the fourth, third, second, and first compaction plates.

The upper side of the inside of the fixing head is provided with a spring groove, and the inside of the spring groove contains a fixing spring. Both ends of the fixing spring are connected to a rectangular fixing block, and the upper end surface of the rectangular fixing block is an inclined surface.

[0010] Preferably, the first, second, third, fourth, and fifth tamping plates have the same thickness, and are made of the same material.

[0011] Preferably, a fixing through hole is provided on both sides of the upper surface of the second, third, fourth, and fifth tamping plates near the inner side.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model has a first tamping plate fixed to the lower end of the cylindrical shell of the tamping device, and a second, third, fourth and fifth tamping plates are provided above the first tamping plate. When this equipment is needed to tamp the foundation backfill, the second, third, fourth or fifth tamping plates can be installed according to the size of the space where the foundation backfill is located, so as to change the area of ​​the tamping surface that applies impact force to the foundation backfill.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] The cylindrical outer shell 1 (model JY03), the compaction cylinder 3 (model SC32), and the return spring 21 (model JX110) mentioned in this utility model can be obtained from the market or through private customization.

[0023] Please see Figures 1 to 4This utility model provides an embodiment of a foundation backfill soil compaction device, comprising a cylindrical outer shell 1, a first compaction plate 5 fixed to the lower end face of the cylindrical outer shell 1, a second compaction plate 6 above the first compaction plate 5, a third compaction plate 7 above the second compaction plate 6, a fourth compaction plate 8 above the third compaction plate 7, and a fifth compaction plate 9 above the fourth compaction plate 8. The inner wall shapes of the fifth compaction plate 9, the fourth compaction plate 8, the third compaction plate 7, and the second compaction plate 6 correspond to the outer surface shapes of the fourth compaction plate 8, the third compaction plate 7, the second compaction plate 6, and the first compaction plate 5, respectively. Furthermore, the fifth compaction plate 9, the fourth compaction plate 8, the third compaction plate 7, and the second compaction plate 6 are respectively larger than the fourth compaction plate 8, the third compaction plate 9, the third compaction plate 9, the third compaction plate 6, and the first compaction plate 5. The equipment comprises a tamping plate 7, a second tamping plate 6, and a first tamping plate 5. Above the first tamping plate 5 are a second tamping plate 6, a third tamping plate 7, a fourth tamping plate 8, and a fifth tamping plate 9. When this equipment is needed to compact the foundation backfill, the second tamping plate 6, the third tamping plate 7, the fourth tamping plate 8, or the fifth tamping plate 9 can be installed according to the size of the space where the foundation backfill is located. This changes the size of the tamping surface that applies impact force to the foundation backfill. Through the above technical solution, the equipment can change the size of the tamping surface that applies impact force to the foundation backfill according to the size of the space where the foundation backfill is located, making it easy to compact foundation backfill located in a narrow space, thereby improving the flexibility of the equipment.

[0024] The compaction device has a compaction cylinder 3 fixedly installed inside the cylindrical shell 1. The lower end of the piston rod of the compaction cylinder 3 is fixed with a compaction pressure transmission block 4. When it is necessary to use the first compaction plate 5 to apply impact force to the foundation backfill soil located in a narrow space, the first compaction plate 5 is attached to the upper end of the foundation backfill soil. Then, the compaction cylinder 3 is started to move the compaction pressure transmission block 4 up and down in a cycle. When the downwardly moving compaction pressure transmission block 4 contacts the inner wall of the cylindrical shell 1 of the compaction device, a downward pressure can be applied to the cylindrical shell 1 of the compaction device, and the foundation backfill soil can be compacted by this downward pressure.

[0025] A pull ring 2 is installed on both sides of the upper end face of the cylindrical shell 1 of the compaction device, and the cylindrical shell 1 of the compaction device and the pull ring 2 are connected by a rotating shaft. Before installing the second compaction plate 6, the third compaction plate 7, the fourth compaction plate 8 and the fifth compaction plate 9, the pull ring 2 is adjusted to a vertical state by the rotating shaft structure between the cylindrical shell 1 of the compaction device and the pull ring 2, so as to prevent the pull ring 2, which is in a parallel state, from obstructing the second compaction plate 6, the third compaction plate 7, the fourth compaction plate 8 and the fifth compaction plate 9.

[0026] A fixing head 10 is fixed at both ends of the upper surface of the first tamping plate 5, the second tamping plate 6, the third tamping plate 7, and the fourth tamping plate 8 near the outer side. A spring groove 11 is provided on the upper side inside the fixing head 10, and a fixing spring 12 is contained inside the spring groove 11. A rectangular fixing block 13 is connected to both ends of the fixing spring 12, and the upper end surface of the rectangular fixing block 13 is an inclined surface 21. A fixing through hole 14 is provided on both sides of the upper surface of the second tamping plate 6, the third tamping plate 7, the fourth tamping plate 8, and the fifth tamping plate 9 near the inner side. The positions of the fixing through holes 14 on the outer surfaces of the second tamping plate 6, the third tamping plate 7, the fourth tamping plate 8, and the fifth tamping plate 9 correspond to the positions of the fixing heads 10 fixed to the outer surfaces of the first tamping plate 5, the second tamping plate 6, the third tamping plate 7, and the fourth tamping plate 8, respectively. When the second tamping plate 6 needs to be installed, the two fixing through holes 14 on the outer surface of the second tamping plate 6 are separated. Align the two fixing heads 10 fixed to the upper surface of the first tamping plate 5, and fasten the second tamping plate 6 onto the upper surface of the first tamping plate 5. During the process of fastening the second tamping plate 6 onto the upper surface of the first tamping plate 5, the fixing heads 10 will also be inserted into the interior of the fixing through hole 14. As the fixing heads 10 go deeper, the rectangular fixing block 13 located on the outer surface of the fixing head 10 will come into contact with the entrance of the fixing through hole 14. Through the inclined surface 21 located on the upper surface of the rectangular fixing block 13, as the fixing head 10 goes deeper, the rectangular fixing block 13 will be pushed inward and squeeze the fixing spring 12. When the rectangular fixing block 13 has completely passed the fixing through hole 14, the reaction force of the squeezed fixing spring 12 can push the rectangular fixing block 13 outward and make it stuck on the upper surface of the second tamping plate 6. When the rectangular fixing block 13 is stuck on the upper surface of the second tamping plate 6, the second tamping plate 6 and the first tamping plate 5 can be fixed together.

[0027] A cylindrical groove 17 is provided on one side of the fixed through hole 14. A return spring 20 is contained inside the cylindrical groove 17. A circular plate 19 is connected to the upper end face of the return spring 20. A connecting rod 18 is fixedly connected to the upper end face of the circular plate 19. A disassembly ring 15 is fixedly connected to the upper end face of the two connecting rods 18. A cylindrical pushing groove 16 is provided at the lower end face of the disassembly ring 15 corresponding to the fixed through hole 14. When it is necessary to release the fixation of the second compaction plate 6, press down on the disassembly ring 15 located above the second compaction plate 6. As the disassembly ring 15 descends, the inclined surface 21 on the upper end face of the rectangular fixing block 13 will contact the entrance of the cylindrical push groove 16 on the lower end face of the disassembly ring 15. As the disassembly ring 15 descends, the rectangular fixing block 13 will be gradually pushed inward. When the rectangular fixing block 13 is completely inside the spring groove 11 and its lower end face is no longer in contact with the upper end face of the second tamping plate 6, the fixation between the first tamping plate 5 and the second tamping plate 6 is released, and then the second tamping plate 6 can be directly removed from the first tamping plate 5.

[0028] The disassembly and assembly methods of the third compaction plate 7, the fourth compaction plate 8, and the fifth compaction plate 9 are the same as those of the second compaction plate 6. Through the above technical solution, the second compaction plate 6, the third compaction plate 7, the fourth compaction plate 8, and the fifth compaction plate 9, which are used to change the area of ​​the compaction surface that applies impact force to the foundation backfill soil, can be quickly disassembled and assembled, thereby improving the convenience of using this equipment.

[0029] When the disassembly ring 15 is pushed downward, the circular plate 19 connected to it via the connecting rod 18 will move downward together and squeeze the return spring 20. Through the reaction force of the squeezed return spring 20, when the second compaction plate 6 is removed, the disassembly ring 15 can be pushed back to its original position. The above technical solution can prevent the lower end face of the disassembly ring 15 from being in constant contact with the second compaction plate 6, thereby preventing the rectangular fixing block 13 from being stuck on the upper end face of the second compaction plate 6.

[0030] The first tamping plate 5, the second tamping plate 6, the third tamping plate 7, the fourth tamping plate 8, and the fifth tamping plate 9 have the same thickness, and are made of the same material. This structure ensures the flatness of the lower surface of the tamping surface that applies impact force to the foundation backfill soil, even when the area can be changed.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
