BACKGROUND

Technical Field

The present disclosure belongs to the technical field of slope support structures, and particularly relates to a compaction device for slope support, and a use method therefor.

Description of Related Art

It is common to establish a first-level slope and a second-level slope in the field of deep foundation pit engineering. However, loose topsoil on a slope surface is widespread and has a significant negative impact on slope stability. From the perspective of a principle of the slope stability, the loose topsoil, owing to its low shear strength, is highly prone to sliding failure with a small internal friction angle and cohesion according to a Coulomb's earth pressure theory when a slope bears its own weight, groundwater pressure, and external additional loads (such as construction mechanical vibration and material stacking), thereby significantly weakening overall stability of the slope.

A traditional support structure, such as a reinforcement plate, exhibits significant defects when coping with such an issue. Typically, this type of reinforcement device is directly fixed on a surface layer of the slope, and the reinforcement plate is unadjustable once it is fixed, making it impossible to effectively compact a soil layer.

For example, Chinese Patent CN 211113673 U disclosed a support structure for a deep foundation pit slope. Specifically, a sandbag is compacted by arranging a supporting assembly at a connecting rod. The supporting assembly is a supporting rod, and has a point of action of only a single point, resulting in an incapability to uniformly compact the slope.
