Technical Field

[0001] The utility model relates to the technical field of hollow box retaining walls, in particular to a retaining wall structure which also doubles as a water box culvert. Background Art

[0002] Empty box retaining walls are widely used in canal engineering and are developing rapidly. Many scholars have conducted research on components, loads, and construction techniques. In order to expand the use of this structure, it is necessary to conduct targeted research on it. Although retaining walls are often used in water-passing occasions such as river bank protection, there are often additional water-passing needs that need to be separated from the river. Generally, new box culverts or channels are used, but the investment in new structures is often high and the economy is poor.

[0003] Based on the above situation, the utility model proposes a retaining wall structure which also serves as a water box culvert, which can effectively solve the above problems. Utility Model Content

[0009] Furthermore: the retaining wall body includes a front side wall and a rear side wall, the top of the front side wall and the rear side wall are provided with a top plate that connects the two, and the bottom of the front side wall and the rear side wall are provided with a bottom plate that connects the two.

[0010] Furthermore: a middle partition is arranged in the empty box along the flow direction of water, and the middle partition simultaneously separates the upper space and the lower space.

[0011] Furthermore: the top elevation of the front side wall is higher than the top elevation of the top plate.

[0012] Furthermore: extension parts are arranged on both sides of the bottom plate, and the extension parts on both sides extend out of the front side wall and the rear side wall respectively.

[0013] Furthermore: the bottom of the bottom plate is provided with a tooth groove at the bottom of the area below the front side wall.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] The utility model divides and layers the inner hollow box body of the existing hollow box retaining wall, and can increase the water passing function on the basis of ensuring the original structural function through the water passing hollow box, thereby effectively reducing the investment in newly building a water passing structure.

[0020] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0021] like Figure 1-3 As shown, a retaining wall structure which also serves as a water culvert, the retaining wall body includes a front side wall 7 and a rear side wall 8, the top of the front side wall 7 and the rear side wall 8 are provided with a top plate 10 which is connected to both, and the bottom of the front side wall 7 and the rear side wall 8 are provided with a bottom plate 5 which is connected to both; an empty box body is provided inside the retaining wall body, and a horizontal partition 6 is provided to separate the middle area of ​​the empty box body of the retaining wall body, and the empty box body is divided into upper and lower layers by the horizontal partition 6, so that the upper space inside the empty box body forms a water-passing empty box 2, and the lower space forms a backfilling empty box 3, and the two side ends of the water-passing empty box 2 are provided with water inlets and outlets which penetrate the retaining wall body.

[0022] In this embodiment, the retaining wall structure can realize a water passage that meets the water passing requirements in the target construction area through the water passing empty box 2. At the same time, the area occupied by the upper space of the retaining wall body is larger than the area occupied by the lower space, so that a large area of ​​water can be effectively guided while ensuring overall stability.

[0023] like Figure 1-2As shown, a middle partition 9 is arranged in the empty box along the water flow direction, and the two side end surfaces of the middle partition 9 along the water flow direction are flush with the two side end surfaces of the front side wall 7 and the rear side wall 8, and the middle partition 9 separates the upper space and the lower space at the same time. The upper and lower spaces of the empty box are separated by the middle partition 9 to form a multi-compartment empty box.

[0024] like Figure 3 As shown, a rib plate 11 is arranged in the lower space of the empty box body to support the water-passing empty box 2 in the upper space. The lower space of the empty box body is divided into a plurality of independent small empty boxes by the middle partition wall 9 and the rib plate 11. The empty box 3 is backfilled with filling materials such as slag and soil to increase the stability of the retaining wall structure.

[0025] like Figure 1 As shown, the front side wall 7 is provided with a wall top 1 at its top, so that the top elevation of the front side wall 7 is higher than the top elevation of the top plate 10 .

[0026] like Figure 1 As shown, extensions are arranged on both sides of the bottom plate 5, and the extensions on both sides extend out of the front side wall 7 and the rear side wall 8 respectively. In addition, a tooth groove 4 is arranged at the bottom of the extension of the bottom plate 5 below the front side wall 7, and the bottom elevation of the tooth groove 4 is lower than the bottom elevation of the bottom plate 5.

[0027] In this embodiment, the entire wall body of the retaining wall structure is made of C30F50W6 concrete.

[0028] See also Figure 1-3 When the retaining wall structure is used in actual engineering construction, the specific contents are as follows:

[0029] First, cast the tooth groove 4 and the bottom plate 5, then cast the front side wall 7, the rear side wall 8, the middle partition plate 9, and the rib plate 11 upward in layers, and after backfilling the lower part of the empty box with stones, soil and other backfill materials, cast the horizontal partition wall 6 and continue to cast the front side wall 7, the rear side wall 8, the middle partition plate 9, the top plate 10 and the wall top 1 upward. After the casting is completed, backfill the soil on the back side of the rear side wall 8 and above the top plate 10.

[0030] The above embodiment is only a preferred technical solution of the present invention. Those skilled in the art should understand that the technical solutions or parameters in the embodiments can be modified or replaced without departing from the principle and essence of the present invention, and all should be included in the protection scope of the present invention.
