Description

Technical Field

[0001] This utility model relates to the field of dynamic compaction replacement hammer technology, and in particular to a dynamic compaction replacement hammer. Background Technology

[0002] Dynamic compaction replacement is a method used to reinforce saturated soft clay foundations. The reinforcement mechanism of dynamic compaction replacement differs from dynamic compaction. It utilizes the high impact energy generated by the high drop of a heavy hammer to forcefully squeeze high-performance materials such as crushed stone, rubble, and slag into the foundation, forming granular mounds. The soil between these mounds forms a composite foundation, improving the bearing capacity and reducing settlement. During dynamic compaction replacement, the soil structure is damaged, and excess pore water pressure is generated in the foundation soil. However, the soil structure strength recovers over time. The granular mounds generally have good permeability, facilitating the dissipation of excess pore water pressure and resulting in consolidation. Existing dynamic compaction replacement hammers have at least the following drawbacks: 1. The existing dynamic compaction replacement hammers are not securely connected, making them prone to shaking and displacement during use; 2. Existing dynamic compaction replacement hammers are difficult to replace. Therefore, we introduce a new dynamic compaction replacement hammer. Utility Model Content

[0025] Please see Figure 1-5 This utility model provides a technical solution:

[0026] A dynamic compaction replacement hammer includes a connecting component 1. A connecting block 2 is inserted through the upper end of the connecting component 1. A connecting rod 4 is fixedly connected to the middle of the upper end of the connecting block 2. Several reinforcing blocks 5 are fixedly connected in a ring array on the outer surface of the connecting rod 4. Several fixing screws 3 are inserted through the upper end of the connecting block 2 in a ring array, and the several fixing screws 3 are staggered with the several reinforcing blocks 5. A replacement hammer assembly 6 is sleeved on the lower end of the connecting component 1. A fixing ring 7 is fixedly sleeved on the lower part of the outer surface of the connecting component 1, and the fixing ring 7 is located on the upper part of the replacement hammer assembly 6.

[0027] In this embodiment, the connecting component 1 includes a support block 11, a connecting groove 12 is opened in the middle of the upper end of the support block 11, a circular groove 13 is opened in the middle of the lower end of the support block 11, an anti-slip pad 14 is fixedly connected to the inner wall of the circular groove 13, the support block 11 is sleeved with the connecting block 2, the circular groove 13 is sleeved with the insert block 64, and a plurality of fixing screws 3 pass through the connecting block 2 and are inserted and connected to the connecting component 1.

[0028] The above solution allows for easy connection between the displacement hammer assembly 6 and the connecting block 2 via the connecting groove 12 on the connecting component 1, and the anti-slip pad 14 in the circular groove 13 enhances the stability between the displacement hammer assembly 6 and the connecting component 1, thereby improving the stability of the displacement hammer assembly 6 during use.

[0029] In this embodiment, the displacement hammer assembly 6 includes a hammer body 61. Several supporting screws 62 are fixedly connected to the upper end of the hammer body 61 in a ring array. An insert block 64 is fixedly connected to the middle of the upper end of the hammer body 61. A reinforcing layer 63 is sleeved on the outer surface of the several supporting screws 62. A crushing layer 65 is fixedly connected to the lower end of the hammer body 61. The insert block 64 is inserted and connected to the connecting assembly 1. The several supporting screws 62 are all inserted and connected to the fixing ring 7.

[0030] The above scheme facilitates the dynamic compaction of the foundation by means of the displacement hammer assembly 6. The insert block 64 is inserted into the circular groove 13 on the connecting assembly 1, which strengthens the connection between the displacement hammer assembly 6 and the connecting assembly 1. Several support screws 62 are inserted into the fixing ring 7 and fixed by nuts, which can position the displacement hammer assembly 6 and improve stability. The foundation can be dynamically compacted by means of the crushing layer 65. The connection, installation and disassembly between the displacement hammer assembly 6 and the connecting assembly 1 are convenient.

[0031] It should be noted that this utility model is a dynamic compaction displacement hammer. During use, firstly, the connecting groove 12 on the connecting component 1 is sleeved with the connecting block 2. This design makes the connection between the displacement hammer assembly 6 and the connecting block 2 simple and quick. Next, several fixing screws 3 pass through the connecting block 2 and are inserted into the connecting component 1, thus fixing the connection between the connecting component 1 and the connecting block 2. This fixing method ensures a tight connection between the two, preventing loosening or detachment during use. The circular groove 13 on the connecting component 1 is sleeved with the insert block 64 on the displacement hammer assembly 6. This design not only achieves the connection between the two, but the anti-slip pad 14 inside the circular groove 13 also enhances the friction between the displacement hammer assembly 6 and the connecting component 1, thereby improving the overall stability. Several supporting screws 62 are provided on the displacement hammer assembly 6. These supporting screws 62 are all inserted into the fixing ring 7 and fixed with nuts. This design further secures the displacement hammer assembly 6. The position of the hammer is precisely defined to prevent displacement or shaking during use, thereby improving the working efficiency and safety of the dynamic compaction hammer. When the dynamic compaction hammer is activated and lowered, the crushed layer 65 on the hammer assembly 6 contacts the foundation and generates a strong impact force. This impact force can effectively crush and compact the foundation, achieving the purpose of dynamic compaction. Because the connection between the hammer assembly 6 and the connecting assembly 1 is firm and stable, even if a large reaction force is generated during the crushing and compaction of the foundation, the dynamic compaction hammer can maintain a stable working state without loosening or falling off. This design of the dynamic compaction hammer also takes into account the convenience of installation and disassembly. The connection and fixation between the hammer assembly 6 and the connecting assembly 1 can be achieved through simple splicing and fixing operations. Similarly, the separation and disassembly of the two can be easily achieved by removing the nuts on the fixing screw 3 and the support screw 62. This design not only improves working efficiency but also facilitates the maintenance and upkeep of the equipment.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
