[0001] The invention belongs to the technical field of slope support structures, and in particular relates to a compaction device for slope support and a use method thereof. Background Art

[0002] In the field of deep foundation pit engineering, the setting of primary and secondary slope reduction is more common. However, the soft soil on the surface of the slope is a common phenomenon, which has a significant negative impact on the stability of the slope. From the perspective of slope stability principle, the soft soil on the surface has low shear strength. When the slope is subjected to its own gravity, groundwater pressure and external additional loads (such as construction machinery vibration, material stacking, etc.), according to Coulomb's earth pressure theory, it is very easy to cause sliding failure due to its small internal friction angle and cohesion, which seriously weakens the overall stability of the slope.

[0003] Traditional support structures such as reinforcement plates have obvious shortcomings in dealing with this problem. Such reinforcement devices are usually directly fixed to the surface of the slope. Once the reinforcement plates are fixed, they cannot be adjusted, and effective compaction of the soil layer cannot be achieved.

[0004] For example, Chinese patent CN211113673U discloses a deep foundation pit slope support structure, which compacts sand bags by setting a support assembly at the connecting rod. The support assembly is a support rod, and the action point is only one point, which cannot achieve uniform compaction of the slope. Summary of the invention

[0007] Furthermore, the connecting frame includes a fixing frame and fixing plates hingedly connected to the upper and lower ends of the fixing frame, the compacting plate is arranged in the fixing frame, the fixing plate is provided with an opening, and a fixing rod is arranged in the opening to fix the connecting frame on the slope.

[0008] Furthermore, upper and lower sides of the fixing frame are provided with limiting structures for limiting the pressing plate.

[0009] Furthermore, the adjustable connecting rod structure includes a connecting rod and an adjusting rod, both ends of the adjusting rod are respectively inserted into the connecting rods on both sides and connected by locking screws, and the connecting rod passes through the through hole of the connecting plate.

[0010] Furthermore, a connecting structure is provided on the outer side of each of the fixed frames of the two groups of compaction structures on both sides of the compaction device, and the connecting structure includes a grooved mounting frame and a fixed screw. Plug holes are respectively provided at both ends of the adjustable connecting rod structure, and the fixed screw passes through the second threaded hole and the plug hole on the grooved mounting frame in sequence to realize a fixed connection between the adjustable connecting rod structure and the fixed frame.

[0012] The beneficial effects of the present invention are: The present invention adopts a plate compaction method, which makes the compaction surface larger. At the same time, the top pressure plate structure can move along the connecting rod to achieve compaction of different areas, making the compaction surface larger and the compaction more effective. At the same time, the connecting rod itself is detachable and adjustable, so that the connecting rod can be used in different scenarios and has a wider applicability.
