Description

Technical Field

[0001] The utility model relates to the technical field of building reinforcement structures, and more specifically to a cantilever retaining wall reinforcement structure. Background Art

[0002] The cantilever retaining wall is composed of three reinforced concrete components: the vertical wall, the toe plate and the heel plate. The stability of the retaining wall is mainly maintained by the weight of the backfill on the bottom plate. The cantilever retaining wall is a light retaining structure. The anti-slip and anti-overturning of its retaining structure mainly depends on the gravity effect of the deadweight of the wall and the backfill soil (including the load) above the bottom plate of the wall. Due to its small structure and light deadweight, the cantilever retaining wall is often used in fill areas where stone is scarce and the bearing capacity of the foundation is low.

[0003] In construction, anchor ropes and drainage holes are generally used to enhance the stability of cantilever retaining walls (taking patent CN213173811U as an example). However, the side area of ​​the retaining wall is large, and there is still a problem of insufficient support. In addition, the limited site makes it inconvenient for workers to reinforce and construct a large supporting structure. Therefore, it is easy to cause the wall to tilt and deform or even crack, posing a major safety hazard. Utility Model Content

[0004] The utility model aims to provide a cantilever retaining wall reinforcement structure, which solves the problem that the cantilever retaining wall foundation is unstable and it is difficult to reinforce it on a limited site, resulting in the retaining wall tilting, deformation and cracking.

[0006] In order to further increase the strength of the connection between the retaining wall and the multiple supporting columns, as a preferred cantilever retaining wall reinforcement structure of the utility model, a concrete reinforcement layer is poured between the retaining wall and the multiple supporting columns, and a steel mesh is fixed inside the concrete reinforcement layer.

[0007] In order to prevent the retaining wall from deforming and cracking by the tension of the prestressed anchor cable, as a preferred cantilever retaining wall reinforcement structure of the utility model, one end of the prestressed anchor cable is fixedly connected to the supporting column, and the other end passes through the concrete reinforcement layer, the retaining wall and penetrates into the soil in sequence.

[0008] In order to discharge the accumulated water flowing down the slope direction, as a preferred cantilever retaining wall reinforcement structure of the utility model, a plurality of drain pipes are connected through the retaining wall and the concrete reinforcement layer, and a reverse filter bag is fixedly installed at one end of the plurality of drain pipes located on the outside of the retaining wall.

[0009] In order to improve the corrosion resistance of the drain pipe, as a preferred cantilever retaining wall reinforcement structure of the utility model, the material of the drain pipe is PVC plastic material.

[0010] The beneficial effects of the utility model are as follows:

[0011] 1. By adopting supporting piles + supporting columns + prestressed anchor cables to form an overall stable structure, the reinforced structure can achieve a stable foundation, simplify the reinforced structure, and reduce the volume of reinforcement, thus fundamentally solving the problems of unstable foundation of cantilever retaining wall, limited space that cannot be reinforced, and serious tilt and deformation of retaining wall;

[0012] 2. By pouring concrete between the retaining wall and multiple supporting columns to form a concrete reinforcement layer, the retaining wall and the supporting columns can be more closely connected. The steel mesh is located inside the concrete reinforcement layer to improve the strength of the reinforcement layer. BRIEF DESCRIPTION OF THE DRAWINGS
