Description

Technical Field

[0001] The present invention relates to the technical field of dynamic compaction devices for dams, and more specifically, to a dynamic compaction treatment device for stabilizing the foundation of a dam. Background Art

[0002] A dynamic compactor is a machine used in the construction process to compact loose soil. During construction, a winch hoists a rammer high into the air through a steel rope. The dynamic compaction method was first developed by Menard in France for ground reinforcement, that is, using a rammer weighing more than ten tons to fall from a high place, repeatedly impacting the ground multiple times to strongly compact the foundation. This powerful impact generates stress and vibration in the foundation. The longitudinal and transverse waves emitted from the ground impact points can reach deep into the formation, thereby achieving different degrees of reinforcement for the shallow and deep layers. When constructing a dam, it is necessary to use a dynamic compactor to perform multiple compaction operations on the soil surface of the dam.

[0003] After retrieval, according to the patent network, there is an automatic hook height-fixed and decoupled dynamic compactor, which includes a lifting device, a positioning hook device, and a guide rod rammer. The positioning hook device includes a hydraulic cylinder and a guide shield. The hydraulic cylinder is connected to an electro-hydraulic control device. The piston rod of the hydraulic cylinder is hinged to a hook and a spring through a pin shaft. The upper end of the spring is hung on the upper part of the hydraulic cylinder. A limit plate is fixed on the guide shield, and a limit pin is provided below the limit plate. Both ends of the hook extend above the limit pin, and the lower part of the guide shield is a flared opening; the guide rod rammer includes a guide head, a positioning cylinder, and a rammer body. The upper part of the guide head is conical, and the lower part is a frustum that cooperates with the hook. The upper part of the positioning cylinder is conical and the lower part is cylindrical. In this invention, there is no need for manual hanging of the hook, which can increase the safety factor, reduce the labor intensity of workers, and improve work efficiency.

[0004] However, when the existing dynamic compactor is in use, although it can perform good suspension operations on the compaction block, when the compaction block is suspended for a long time, the effect of scraping and cleaning the wet soil adhering to the surface of the compaction block is not high, which easily causes the soil to be adsorbed on the surface of the compaction block, resulting in a change in the compaction weight. Moreover, when the compaction block is suspended and transported, the synchronous support effect on the bottom of the compaction block is not high, reducing the stability of the compaction block during transportation due to inertia. At the same time, when the compaction block is lifted by a lifting cable, the anti-vibration effect of the cable is not high, and it is easy to cause the cable to sway in windy weather, affecting the construction safety of the compaction block, which does not meet people's usage requirements. Therefore, we propose a dynamic compaction treatment device for stabilizing the foundation of a dam. Summary of the Invention

[0053] As Figure 1 shown, when using this dynamic compaction treatment device for dam foundation consolidation, first, when dynamically compacting the soil on the dam surface through the compaction block 14, in order to improve the effect of conveniently scraping and cleaning the wet soil adhered to the surface of the compaction block 14 during long-term use of the compaction block 14, and the effect of conveniently and stably supporting the bottom of the compaction block 14 when transferring the compaction block 14, when it is necessary to clean the compaction block 14, the second servo motor 15 can be turned on to drive the sliding rod 17 to slide along the inner wall of the fixed groove 18 through the rotation of the second threaded rod 16. The sliding of the sliding rod 17 drives the cleaning scraper 19 to slide centrally through the engagement connection between the bolt 22 and the card slot 23, achieving the effect of conveniently removing the soil on the surface of the compaction block 14. At the same time, when it is necessary to transfer the compaction block 14, the cleaning scraper 19 can be made to contact the bottom of the compaction block 14, achieving the effect of stably supporting and transferring the bottom of the compaction block 14;

[0054] Next, when the compaction block 14 is suspended and installed through the first suspension rod 10 and the second suspension rod 11, in order to improve the stability of the suspension rod for installing and using the compaction block 14 and prevent the compaction block 14 from shaking during use, when the suspension rod expands and contracts, the positioning block 12 can be made to fit the surface of the suspension ring 13 and drive the connecting clamping rod 2402 to insert into the connecting box 2401. When the inclined surfaces are formed at the extrusion parts of the connecting clamping rod 2402 and the telescopic clamping rod 2403, the telescopic rod 2404 and the spring 2405 are extruded until the connecting parts of the connecting clamping rod 2402 and the telescopic clamping rod 2403 are flat, achieving the effect of clamping and fixing between the suspension rods;

[0055] Finally, when the ramming block 14 is lifted and rammed by a crawler crane, in order to improve the stability of the lifting cable 3 during its up-and-down movement below and prevent the lifting cable 3 from swaying during use, which may cause the ramming block 14 to sway synchronously and pose a safety hazard, when using the lifting cable 3, the third servo motor 2601 can be turned on. Through the rotation of the third threaded rod 2602, the sliding protective cover 2605 is driven to slide along the inner wall of the limit groove 2604. According to the need for the protection length, the fourth servo motor 2606 can be turned on. Through the rotation of the fourth threaded rod 2607, the lifting protective cover 2608 is driven to slide along the inner wall of the sliding protective cover 2605, which plays an effective role in limiting and preventing the sway of the lifting cable 3.
