Embodiment 1

[0024] The combined anti-sliding structure of the corrugated steel cylinder wall includes multiple sets of corrugated steel cylinders arranged vertically to the sliding direction of the expansive rock and soil mass, and the multiple sets of corrugated steel cylinders are linearly arranged at a certain interval. In other embodiments, it can also be According to the shape of the anti-slip surface, it is arranged in a curved line or a broken line. In a word, they form an anti-slip surface near the side of the expansive rock and soil mass. The lower part of each group of corrugated steel cylinders is embedded in the sliding bed. In this embodiment, The depth of the buried corrugated steel cylinder is greater than the height of the exposed corrugated steel cylinder, so as to achieve better anti-slip effect. The backfill filled in the corrugated steel cylinder is the earthwork of the expansive rock and soil excavated on site or the sliding bed .

[0025] The above-mentioned corrugat...

Embodiment 2

[0028] see figure 1 and figure 2 , a combined anti-skid structure with corrugated steel cylinder walls, including multiple groups of corrugated steel cylinders 3 arranged on the expansive rock and soil body 1 and inclined at a small angle in the sliding direction, and the inclination direction of the corrugated steel cylinders 3 is that the upper end is close to the expansive rock and soil body 1 direction, multiple groups of corrugated steel cylinders 3 are arranged in a curved or zigzag shape according to the shape of the anti-slip surface. In the sliding bed 2, in this embodiment, the depth of the corrugated steel cylinder 3 embedded in the sliding bed 2 is greater than the height of the corrugated steel cylinder 3 exposed to the ground, so as to achieve a better and more stable anti-skid effect. The backfill 4 filled in the steel cylinder body 3 is reinforced concrete, including the reinforced mesh compiled earlier and the cement mortar filled later, which together with ...

Abstract

The invention relates to a corrugated steel cylinder wall combined type anti-sliding structure. The corrugated steel cylinder wall combined type anti-sliding structure comprises a plurality of sets of corrugated steel cylinders arranged in the sliding direction of an expansive rock-soil body, the multiple sets of corrugated steel cylinders are arranged at certain intervals, the faces, close to the expansive rock-soil body, of the corrugated steel cylinders form an anti-sliding face, the lower portion of each set of corrugated steel cylinder is embedded in a sliding bed. The corrugated steel cylinders are filled with backfill materials, and corrugated steel plates are connected between the corrugated steel cylinders to form corrugated steel breast boards. According to the corrugated steel cylinder wall combined type anti-sliding structure, a prefabricating and splicing technology is adopted, the corrugated cylinders and corrugated walls can be assembled and spliced in a factory in advance, site construction is simple and rapid, the risk is low, and the economic benefits are remarkable; according to the corrugated steel cylinder wall combined type anti-sliding structure, due to the mechanical properties of corrugated steel and the combination of the corrugated steel, the stress performance is good, and the anti-sliding capacity and the falling stone impact resistance of a section prone to landslide are greatly improved.

Description

technical field [0001] The invention relates to the field of landslide prevention and control, in particular to a corrugated steel cylinder wall combined anti-skid structure. Background technique [0002] Landslide refers to a certain part of the rock and soil on the slope of the mountain under the action of gravity (including the gravity of the rock and soil itself and the dynamic and static pressure of groundwater), which produces shear displacement along a certain weak structural surface (band) and moves downward to the slope as a whole. effects and phenomena. Commonly known as "walking mountains", "collapsing mountains", "slippery ground", "slippery soil" and so on. It is one of the common geological disasters. [0003] In areas with many mountainous areas, various landslide disasters such as collapse, cracking, and retaining wall displacement are prone to occur after the construction of railways or roads. Each has its own limitations. They have disadvantages such as...
