Description

Technical Field

[0001] The present application relates to the technical field of anti-sliding retaining structures, and in particular to a road cutting pile-sheet wall structure. Background Art

[0002] The pile-sheet wall is a slope retaining structure composed of anti-slide piles and retaining plates. This structure has the advantages of good support and reinforcement effect, strong slope shrinkage ability, and can be used for "reverse construction". It is widely used in slope reinforcement and protection or landslide control. In the construction of anti-slide piles, after the construction of the anti-slide piles is completed, the soil in front of the piles of the cantilever section needs to be excavated. In order to avoid soil collapse, it is necessary to construct a retaining plate structure between two adjacent anti-slide piles to support the soil.

[0003] In order to make the anti-sliding pile and the retaining plate jointly bear the soil pressure of the slope or the sliding force of the landslide, the existing technology is to drill holes on the anti-sliding piles that have been cast, plant reinforcement, and weld them with the transverse reinforcement in the retaining plate. The steel cage of the anti-sliding pile is hidden under the protective layer, and the pile body reinforcement is relatively dense. The main disadvantages of the existing technology are as follows: it is very easy to touch the reinforcement when drilling and planting reinforcement, and it is impossible to go deep, resulting in insufficient anchoring depth, which seriously affects the firmness of the anti-sliding pile and the retaining plate; the reinforcement of the anti-sliding pile is relatively hidden, and in order to avoid the reinforcement, it is necessary to constantly test and rework when drilling, which seriously affects the strength and construction progress of the anti-sliding pile; when drilling and planting reinforcement are not careful, it is very easy to drill off the main reinforcement and stirrups of the anti-sliding pile, reducing the bending resistance of the positive section and the shear resistance of the inclined section of the anti-sliding pile, which brings potential threats to slope reinforcement and management. Utility Model Content
