DETAILED DESCRIPTION
[0032] The following is combined with Figure 1 —4 Provide further details of this application.
[0033] The embodiment of the present application discloses a water conservancy project slope support structure. Figure 1 Along the direction away from the riverbank slope 11, the water conservancy project slope support structure includes, in sequence, a first geotextile layer 1 and a gabion layer 2. The first geotextile layer 1 is composed of multiple layers of geotextiles stacked together. The first geotextile layer 1 is laid on the riverbank slope 11 and fixed to the riverbank slope 11 using connectors such as steel chisels, bamboo sticks, or wooden chisels. The gabion layer 2 is composed of a plurality of gabions 3 laid together, with adjacent gabions 3 secured by wire tying; that is, the plurality of gabions 3 are laid on the water-facing side of the riverbank slope 11.
[0034] The gabions 3 of the gabion mesh 4 have an intercepting effect on water flow, thereby reducing the scouring of the river bank slope 11 by water flow; and the first geotextile layer 1 has an intercepting effect on soil, thereby reducing water and soil erosion on the river bank slope 11; that is, through the coordinated cooperation of the first geotextile layer 1 and the gabion layer 2, the erosion of the river bank slope 11 by water flow is reduced, and the stability of the river bank slope 11 is improved.
[0035] Reference Figure 1 and Figure 2 The gabion 3 includes a gabion mesh 4, a filling stone 5 and a water retaining board 6. The filling stone 5 is filled in the gabion mesh 4, the water retaining board 6 is buried in the filling stone 5, and the board surface of the water retaining board 6 is arranged toward the water-facing surface of the river bank slope 11.
[0036] Reference Figure 1 and Figure 2The stone fill 5 includes a first stone fill 51 and a second stone fill 52. The first stone fill 51 is larger than the mesh size of the gabion 4, while the second stone fill 52 is smaller than the mesh size of the gabion 4. The second stone fill 52 fills the gaps between the first stone fill 51. In the prior art, the mesh sizes of gabion 4 include 60mm×80mm, 80mm×100mm, 100mm×120mm, and 120mm×150mm. In this embodiment, the mesh size of the gabion 4 is 80mm×100mm. Accordingly, the minimum diameter of the first stone fill 51 is between 120mm and 250mm, and the maximum diameter of the second stone fill 52 is between 5mm and 50mm. By filling the gaps between the first stone fill 51 with the second stone fill 52, the number and area of flow channels within the gabion 3 are reduced, thereby improving the gabion 4's ability to block water flow, reducing scouring of the riverbank slope 11 and mitigating soil and water loss along the riverbank slope 11.
[0037] Reference Figure 2 and Figure 3 In this embodiment, the retaining plate 6 includes an intercepting portion 61 and a diversion portion 62, which are integrally formed. In the vertically upward direction, the distance between the intercepting portion 61 and the riverbed centerline 9 increases, while the distance between the diversion portion 62 and the riverbed centerline 9 decreases. Furthermore, the water-facing surface of the retaining plate 6 is provided with a plurality of vertically arranged ridges 7, which are integrally formed with the retaining plate 6 and spaced apart along the length of the riverbank slope 11.
[0038] The implementation principle of a water conservancy project slope support structure in the embodiment of the present application is as follows:
[0039] Reference Figures 1 to 3 When water flows over the riverbank slope 11, the stone filling 5 and water retaining plate 6 in the gabion 3 have a significant interception and weakening effect on the water flow, thereby reducing the scouring of the riverbank slope 11 by the water flow, reducing soil erosion on the riverbank slope 11, and improving the stability of the riverbank slope 11. At the same time, the water retaining plate 6 is a continuous structure, so that the water retaining plate 6 has a strong blocking effect on the water flow.
[0040] Reference Figure 1 and Figure 2 When the water flow scours the river bank, the water body at the bottom of the water flow will move upward along the intercepting part 61 of the water retaining plate 6, and flow through the guide part to the middle area of the river, so that the bottom water body of the water flow offsets the scouring of the upper water body, so as to reduce the scouring and erosion of the river bank slope 11 as a whole, and improve the stability of the river bank slope 11.
[0041] Reference Figure 2 and Figure 3 The convex strips 7 on the water-facing surface of the water retaining plate 6 are conducive to the upward flow of the bottom water, so as to further improve the interception effect of the water retaining plate 6 on the water flow.
[0042] The water retaining plate 6 can be a sheet structure such as a galvanized thin steel plate, a rubber sheet, etc.; in this embodiment, the water retaining plate 6 is preferably a galvanized thin steel plate to improve the corrosion resistance of the water retaining plate 6.
[0043] Since the grooves of the river are more easily corroded by the water flow, the slope support structure of the embodiment of the present application can be set in the grooves of the river to improve the stability of the river bank slope 11. In other embodiments, the slope support structure of the present application is set along the river bank.
[0044] Example 2
[0045] The difference between this embodiment 2 and embodiment 1 is that:
[0046] Reference Figure 4 The gabion 3 also includes a planting layer 8, which is positioned on the water-facing surface of the gabion 3 and fixed between the gabion mesh 4 and the rockfill 5. The planting layer 8 serves to attract and secure aquatic plants. In this embodiment, the planting layer 8 comprises a wire loop mat 81 and a second geotextile layer 82. Two wire loop mats 81 are provided, and the second geotextile layer 82 is positioned between the two layers of wire loop mats 81. The wire loop mats 81 and the second geotextile layer 82 are secured together using plastic tape or small wire. In other embodiments, the planting layer 8 is comprised of a wire loop mat 81.
[0047] Reference Figure 4 The wire loop gasket 81 is made of a high-density synthetic resin or plastic. This material is melt-extruded into a filamentous structure, and the filamentous surface is bonded into a plate-like structure using adhesive or hot melt. This creates numerous interconnected channels within the wire loop gasket 81. Wire loop gaskets 81 are also used in automotive floor mats and other fields.
[0048] Reference Figure 4 The numerous channels within the wire loop mat 81 facilitate the anchoring of aquatic plant roots, allowing them to grow on the water-facing surface of the gabion 3. The second geotextile layer 82 between the two wire loop mats provides growth space for aquatic plant seeds and larvae, allowing them to adhere to the water-facing surface of the gabion 3. In other words, by providing the planting layer 8 on the water-facing surface of the gabion 3, a growth area for aquatic plants is provided. Aquatic plants are then used to reduce the scouring and erosion of the riverbank slope 11 by the water flow, further improving the stability of the riverbank slope 11.
[0049] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
