A prefabricated retaining structure suitable for the treatment of small debris flow ditch

Abstract

The invention discloses an assembled retaining structure suitable for the treatment of small-scale mud-rock flow ditches, which includes movable baffles and at least one Binger gabion. The trenches are arranged alternately, the lower end of the fixed column of the movable baffle is buried and fixed in the debris flow ditch bed, the hollow sleeve is set outside the ground part of the fixed column, and the panel is fixed on the annular ferrule outside the hollow casing to form a movable baffle , Binger gabion blocks larger stones, and the panel of the movable baffle can rotate around the fixed cylinder, which can not only play the role of diversion, but also prolong the movement path of the stones, realize energy dissipation, selective blocking, assembled movable baffle The panel, hollow sleeve and fixed column of the slab can be processed in advance, and only need to be assembled on site, saving construction time, and the panel and hollow sleeve can be disassembled, which is convenient for cleaning the accumulated stones, and can be solved individually in case of failure, prefabricated Parts can be reused, saving engineering costs.

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
