Description

Technical Field

[0001] The present application relates to the technical field of slope support components, and in particular to a flexible slope support structure for soft geology. Background Art

[0002] During the construction of expansive soil excavation slopes, since expansive soil is a highly plastic clay formed in the natural geological process that expands and softens when it absorbs water, shrinks and cracks when it loses water, and can repeatedly expand and contract and deform, it has obvious repeated expansion and contraction properties. Slopes that repeatedly expand and contract are prone to fracture, causing the soil on the slope to fall. Therefore, it is necessary to install a support structure at the slope position.

[0003] The existing announcement number is CN207079601U, and the name is a flexible retaining structure for controlling landslides on expansive soil excavation slopes. The excavation slope has a cleared slope surface, a base inclined surface, a crushed stone seepage ditch, a crushed stone permeable layer and a geogrid structure layer. The geogrid structure layer is composed of multiple layers of geogrid structures. Each layer of the geogrid structure is composed of a geogrid that is backfilled with expansive soil and a number of U-shaped nails are set on the geogrid that is backfilled with expansive soil. The above-mentioned flexible retaining is fixed and installed using multiple U-shaped anchor nails.

[0004] With respect to the above-mentioned related technologies, the inventors found that the above-mentioned method of fixing the inverted geogrid is to use multiple U-shaped nails to fix it on the expansive soil excavation slope, but the expansive soil excavation slope is prone to repeated expansion and contraction and fracture, and the fractured expansive soil will fall, and the U-shaped nails fixed on the expansive soil excavation slope will roll down with the expansive soil, thereby pulling the installed inverted geogrid off the slope, resulting in a decrease in the support stability of the expansive soil excavation slope. Utility Model Content
