[0013] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the preferred implementation scheme of the present utility model is described below in conjunction with specific embodiments. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent elements with the same or similar functions. However, it should be understood that the accompanying drawings are only used for illustrative purposes and cannot be understood as limitations on the present utility model. In order to better illustrate the present embodiment, some parts of the accompanying drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product. For those skilled in the art, it is understandable that some well-known structures and their descriptions in the accompanying drawings may be omitted, and the positional relationship described in the accompanying drawings is only used for illustrative purposes and cannot be understood as limitations on the present utility model.
[0014] 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.
[0015] The utility model provides a cross-toe plate construction road structure, such as Figure 1 As shown, it includes a stepped base 1 cast on the toe plate 5, the stepped base 1 is as wide as the toe plate 5, a road foundation 3 is filled on the stepped base 1, a number of reinforced gabions 2 are respectively provided on both sides of the road foundation 3, a concrete pavement 4 is paved on the road foundation 3, and the concrete pavement 4 is flush with the dam surface of the panel dam, so as to facilitate the transportation of the required dam body filling materials from the upstream to the dam surface.
[0016] comprehensive Figure 1 and Figure 2 It can be seen that the toe board 5 extends upwardly at an angle, and correspondingly, the stepped base 1 extends upwardly, the height difference between two adjacent steps is equal, and the surface length of each step is 80 cm.
[0017] The road foundation 3 is composed of several layers of steel-plastic grids 31 and slag foundations 32 distributed at intervals. The upper surface of the stepped base 1 is filled with the slag foundation 32, and a layer of steel-plastic grid 31 is laid between the upper and lower adjacent layers of slag foundations 32. A concrete pavement 4 is laid on the top slag foundation 32.
[0018] A plurality of reinforced gabions 2 are respectively set up with two rows of reinforced gabions on both sides of the road foundation 3, wherein the two rows of reinforced gabions adjacent to the road foundation 3 are at the same height as the road foundation 3, and the height of the other two rows of reinforced gabions is higher than half of the road foundation 3. Figure 1 As shown, since there is a height difference between adjacent steps of the stepped base 1, the number of reinforced gabions 2 in the reinforced gabion group located on the lower side is relatively large. In this embodiment, the reinforced gabion group adjacent to the road foundation 3 and located on the lower side consists of four layers of reinforced gabions 2, while the reinforced gabion group adjacent to the road foundation 3 and located on the higher side consists of two and a half layers of reinforced gabions 2. Three layers of reinforced gabions 2 are arranged on the step one step lower than the four layers of reinforced gabions 2, and one layer of reinforced gabions 2 is arranged on the step one step higher than the two and a half layers of reinforced gabions 2.
[0019] The road foundation 3 is composed of several layers of steel-plastic grilles 31 and slag foundations 32 distributed at intervals. The height of each layer of slag foundation 32 is equal, and the upper surface of the adjacent reinforced gabion 2 on one side of each layer of slag foundation 32 is flush with its upper surface. A layer of steel-plastic grille 31 is laid between two adjacent layers of slag foundation 32, and the steel-plastic grille 31 is laid to the upper surface of the adjacent reinforced gabion 2.
[0020] When the dam body is filled to the elevation where the concrete pavement 4 is located, the concrete pavement 4, the road foundation 3 and the reinforced gabion 2 of the utility model need to be removed, and the stepped base 1 is retained for passage, which is more labor-saving.
