Description

Technical Field

[0001] The present invention belongs to the technical field of slope support structures, and in particular relates to a compacting device for slope support and a method of using the same. Background Art

[0002] In deep foundation pit engineering, first- and second-stage slope reduction is a common practice. However, the prevalence of soft surface soil on slopes significantly negatively impacts slope stability. Based on the Coulomb earth pressure theory, soft surface soil, due to its low shear strength, is susceptible to sliding failure due to its low internal friction angle and cohesion when subjected to its own gravity, groundwater pressure, and external additional loads (such as construction machinery vibration and material stacking). This, in turn, severely 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.
