Due to the requirements of project planning, the available space behind the retaining wall is limited. Landscaping and fencing sometimes have their limitations and cannot meet the requirements of the project planning such as the greening rate. In addition, the traditional retaining wall, because the toe of the wall cannot exceed the road boundary (the red line of the land), causes a waste of land space between the wall panel and the road boundary (the red line of the land), so the traditional retaining wall sometimes cannot meet the actual engineering needs.

[0022] Reference Figure 1-2 As shown, it is a preferred embodiment provided by the utility model.

[0023] The top of the retaining wall 1 is a back-pressure external cantilever structure, comprising a retaining wall 1, on which a cantilever structure is arranged, the cantilever structure comprising a cantilever plate 2, a counter-cantilever plate 4 and a baffle plate 3, the cantilever plate 2 is arranged on the top of the retaining wall 1, the baffle plate 3 is provided at the end of the cantilever plate 2 away from the retaining wall 1, the counter-cantilever plate 4 is connected to the end of the cantilever plate 2 away from the baffle plate 3, and the baffle plate 3 is anchored into the cantilever plate 2 through vertical steel bars.

[0024] By making the structure of the external cantilever plate 2 to meet different engineering needs and reasonably utilize the space, the utilization rate of the space within the planning area can be improved to a certain extent. The size of the baffle plate 3 can be adjusted to use the baffle plate 3 as a road guardrail, which can save extra space for the construction of guardrails, save economic costs, and improve construction efficiency. By arranging some counter-cantilevers, the supporting capacity of the cantilever plate 2 can be improved to ensure the quality of the project.

[0025] Specifically, in this embodiment, two layers of mutually symmetrical steel meshes 5 are arranged in the cantilever plate 2, the counter-cantilever plate 4 and the baffle plate 3. The steel meshes 5 are made by binding a number of transverse steel bars and vertical steel bars. The number of transverse steel bars and the number of vertical steel bars are evenly staggered in the horizontal direction and the vertical direction respectively.

[0026] By arranging the steel mesh 5, the overall structural strength of the cantilever plate 2, the anti-cantilever plate 4 and the baffle plate 3 can be improved, and the project quality and subsequent service life can be guaranteed.

[0027] Specifically, in this embodiment, the cantilever plate 2 is anchored into the retaining wall 1 through the connecting steel bars 6, and the connecting steel bars 6 are L-shaped.

[0028] By providing the connecting steel bars 6, the cantilever slab 2 and the retaining wall 1 can be well connected and fixed, and stability and safety can be ensured.

[0029] Specifically, in this embodiment, the height of the baffle plate 3 is H, and the height between the top surface of the anti-cantilever plate 4 and the top surface of the cantilever plate 2 is 1.2H.

[0030] Since the height difference between the anti-cantilever plate 4 and the cantilever plate 2 is higher than the height difference between the top surface of the baffle plate 3 and the cantilever plate 2 , the support capacity of the cantilever plate 2 close to the baffle plate 3 can be guaranteed.

[0031] Specifically, in this embodiment, the length between the end face of the cantilever plate 2 and the retaining wall 1 is the same as the length between the end face of the counter-cantilever plate 4 and the retaining wall 1. Since the distances between the end faces of the cantilever plate 2 and the counter-cantilever plate 4 and the retaining wall 1 are the same, the balance can be improved and the supporting capacity of the cantilever plate 2 can be guaranteed.

[0032] Specifically, in this embodiment, the cantilever plate 2, the baffle plate 3 and the anti-cantilever plate 4 are all made of reinforced concrete.

[0033] Specifically, in this embodiment, the overhang plate 4 is backfilled with plain fill soil in layers by compaction, the compaction degree is less than 0.9, and the covering soil elevation is the same as the elevation of the overhang plate 2.

[0034] By backfilling the back-up plate 4 with backfill soil, the balance and stability of the cantilever plate 2 can be further ensured.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
