Fabricated supporting structure suitable for small debris flow gully treatment

Abstract

The invention discloses a fabricated supporting structure suitable for small debris flow gully treatment. The fabricated supporting structure comprises movable baffles and at least one gabion stone cage, wherein the movable baffles are arranged behind the gabion stone cages in rows and staggered, and the gabion stone cages are arranged in a staggered manner along the debris flow gully; the lower ends of fixed columns of the movable baffles are embedded and fixed to a debris flow gully bed, hollow sleeves are arranged outside the ground parts of the fixed columns in a sleeving mode, and panelsare fixed on annular clamping sleeves outside the hollow sleeves to form movable baffles; the gabion stone cage blocks larger stones, and the panels of the movable baffles can rotate around the fixedcolumns, so that the movement path of the stones is lengthened while the dividing effect is achieved, and energy dissipation and selective blocking are achieved; the panels, the hollow sleeves and thefixed columns of the fabricated movable baffles can be machined in advance and only need to be assembled on site, so that construction time is saved; and the panels and the hollow sleeves are detachable, so that the accumulated stones are convenient to clear, faults can be independently solved, prefabricated parts can be reused, and engineering cost is saved.

Description

technical field [0001] The invention relates to the technical field of natural disaster prevention and control, in particular to an assembled retaining structure suitable for the control of small debris flow ditches. Background technique [0002] Debris flow is a unique natural disaster that occurs in mountainous areas. Under a specific geographical environment, due to the excessive storage of loose sand and gravel materials in the watershed, under the impact of heavy rain, the loose solids and water bodies form turbid fluids and flow downstream along the ditch bed. A special torrent of movement. Debris flows are characterized by strong destructiveness, sudden eruption, huge energy, and ferocious onslaught. Their overflowing sedimentation, concentrated erosion, blockage of rivers, and diversion of main rivers pose a great threat to people's lives and property. [0003] Debris flow scales are divided into four categories: giant, large, medium and small. Among them, the total...

AI Technical Summary

Problems solved by technology

For the protection of such small debris flows, it is overkill and relatively uneconomical to apply the existing medium and large prevention and control technologies. Therefore, it is particularly important to construct an economical, safe, simple and reusable retaining structure system for the protection of small debris flow ditches. important
