[0024] The following is combined with Figure 1-4 The embodiments of the present utility model are described in detail.

[0025] Example 1

[0026] The utility model relates to a river slope protection structure, comprising a first slope protection surface 1 on the water-facing side, wherein a plurality of concrete cross beams 11 and a plurality of concrete vertical beams 12 are arranged on the first slope protection surface 1; wherein the concrete cross beams 11 are arranged on the first slope protection surface 1 in a direction parallel to the water flow; the concrete vertical beams 12 are arranged on the first slope protection surface 1 in a direction perpendicular to the water flow; the plurality of concrete cross beams 11 are respectively perpendicularly intersected with the plurality of concrete vertical beams 12 to form a plurality of first grids, each of the first grids is provided with a plurality of gabion boxes 2, and each of the gabion boxes 2 is filled with stones.

[0027] Specifically, due to long-term scouring of the river, the scouring effect of the river water will gradually erode the river bank, causing the river bank line to retreat, the terrain to change, and even possible geological disasters such as landslides; and as the river bank continues to retreat, the width of the river channel may increase, resulting in a decrease in flood control ability and an increase in the risk of flooding. Therefore, in order to prevent the occurrence of the above disasters or risks, such as Figure 1 As shown, a river slope protection structure is provided, wherein the water-facing side is a first slope protection surface 1, and water flows over the first slope protection surface 1. The direction of the water flow here is the direction of the water flow at this location determined according to the length direction of the river channel, and the first slope protection surface is provided on one side of the width direction of the river channel. Furthermore, a plurality of concrete cross beams 11 and a plurality of concrete vertical beams 12 are provided on the first slope protection surface 1, and the plurality of concrete cross beams 11 and a plurality of concrete vertical beams 12 intersect to form a plurality of first grids, and then a plurality of gabion boxes 2 are placed in the first grids, and the gabion boxes 2 are filled with protective materials such as stones to enhance the stability of the slope protection structure and prevent the water flow from scouring the slope surface. In the present application, the mesh of the gabion box 2 is a regular hexagonal mesh, and the mesh diameter is 10-12 cm.

[0028] Each gabion box 2 is arranged in sequence and fills the first frame. Since the first frame is composed of a concrete cross beam 11 and a concrete vertical beam 12, when the gabion box 2 is filled with stones, under the constraint of the first frame of the concrete structure, the gabion box 2 will not be displaced even under the scouring of river water, which ensures the safety of the slope protection structure and makes the entire slope protection structure more stable.

[0029] It should be noted that the gabion box 2 in the present application has two sizes, namely 1# gabion box 25m×1m×1m and 2# gabion box 25m×1m×1.5m, and in order to further improve the durability and protection effect of the slope protection structure, the gabion box 2 here is hot-dip galvanized special-section low-carbon steel wire + PVC coating, and the steel wire diameter is 3mm.

[0030] In addition, in order to further improve the flood resistance of the river slope protection structure, a certain number of energy dissipation facilities can be set up on the water-facing side of the river slope protection structure, such as energy dissipation sills and energy dissipation pools. These energy dissipation facilities can effectively reduce the impact of water flow and reduce the water pressure on the river slope protection structure, thereby improving its flood resistance and ensuring the safety and stability of the river.

[0031] Example 2

[0032] The present embodiment is an improvement made on the basis of the embodiment 1, and the difference lies in that a plurality of spacers 3 are arranged in each of the gabion boxes 2, and the spacers 3 include a plurality of first spacers 31 arranged along the length direction of the gabion boxes 2 and a plurality of second spacers 32 arranged along the width direction of the gabion boxes 2, the plurality of first spacers 31 are parallel to each other, and the plurality of second spacers 32 are parallel to each other; the first spacers 31 and the second spacers 32 are both detachably connected to the gabion boxes 2, and the first spacers 31 and the second spacers 32 divide the interior of the gabion boxes 2 into a plurality of second grids, and the second grids are each filled with stone.

[0033] Specifically, in order to evenly distribute the stones in the gabion box 2 and ensure the stability and durability of the overall structure, a number of spacers 3 are provided in the gabion box 2. The function of these spacers 3 is not only a simple partition, but also a reasonable planning of the internal space of the entire box. By reasonably distributing the spacers 3, the accumulation and displacement of the stones in the gabion box 2 can be effectively prevented. At the same time, the spacers 3 also play a role in guiding the stones, so that the stones can be evenly dispersed along the direction of the spacers 3 when filling the box, avoiding excessive concentration of stones in a certain area.

[0034] More specifically, Figure 4 As shown, the spacer 3 includes a first spacer 31 arranged in the length direction of the gabion box 2 and a second spacer 32 in the width direction, thereby dividing the internal space of the entire gabion box 2 into a number of small grids of equal size, and filling each small grid with stones respectively, so that the weight in each small grid is maintained at a basically consistent level, so that the stones in the entire gabion box 2 are evenly distributed in the gabion box 2, that is, due to the presence of the spacer 3, the gaps between the stones are maintained, so that the force of river scouring on the entire gabion box 2 is roughly equal, its service life is extended, and the entire slope protection structure is more stable.

[0035] It should be noted that in the present application, the spacers 3 are arranged at intervals of 1 m in the gabion box 2, that is, the interval between two adjacent first spacers 31 in the length direction is 1 m, and the interval between two adjacent second spacers 32 in the width direction is also 1 m, and the mesh specifications and materials of the first spacers 31 and the second spacers 32 are consistent with the mesh size and material on the gabion box 2, thereby ensuring the consistency of the overall performance of the entire gabion box 2.

[0036] In practical applications, the number, shape and position of the spacers 3 can be adjusted according to different engineering requirements and terrain conditions.

[0037] Example 3

[0038] This embodiment is an improvement made on the basis of Embodiment 1, the difference being that an anti-collision toe wall 4 is provided at the bottom of the first slope protection surface 1, the anti-collision toe wall 4 is formed by paving a plurality of the gabion boxes 2, the anti-collision toe wall 4 is transversely arranged at the bottom end of the first slope protection surface 1, and the top of the anti-collision toe wall 4 is flush with the top of the gabion box 2 on the first slope protection surface 1 close to the anti-collision toe wall 4.

[0039] Specifically, in order to stably fix the gabion box 2 on the first slope protection surface on the water-facing side, as shown in FIG. Figure 1 As shown, an anti-collision toe wall 4 is arranged at the bottom of the first slope protection surface 1. The anti-collision toe wall 4 is paved with a plurality of gabion boxes 2. In order to ensure a tighter connection between the gabion boxes 2 and the anti-collision toe wall 4 and prevent water from flowing through the gap between the two, thereby further enhancing the integrity and stability of the slope protection structure, the top of the anti-collision toe wall 4 is flush with the top of the gabion boxes 2 on the first slope protection surface 1 close to the anti-collision toe wall 4.

[0040] In addition, the anti-scouring toe wall 4 can also effectively disperse the impact force of the water flow on the slope surface, reducing the scouring effect of the water flow on the slope surface.

[0041] Example 4

[0042] This embodiment is an improvement made on the basis of Embodiment 1, the difference being that a concrete top beam 5 is provided on the top of the first slope protection surface 1, and the concrete top beam 5 is arranged on the top of the first slope protection surface 1 along a direction parallel to the water flow.

[0043] Specifically, in order to enhance the overall stability of the slope protection and fix the slope protection surface, such as Figure 1 As shown, a concrete top beam 5 is also arranged on the top of the first slope protection surface 1, and the concrete top beam 5 is arranged transversely along the first slope protection surface 1 at the top of the first slope protection surface. This layout enables the top beam to evenly distribute pressure, effectively preventing the loosening and sliding of the slope soil. At the same time, the transversely arranged top beam can also effectively resist the impact force caused by natural forces such as wind, rain, and water flow, further protecting the stability of the slope.

[0044] Example 5

[0045] The present embodiment is an improvement on the basis of the embodiment 2, the difference being that each of the gabion boxes 2 has an opening, the opening is covered with a mesh cover 10, the mesh cover 10 has meshes, the specifications and materials of the meshes are the same as those of the meshes on the gabion boxes 2, and the mesh cover 10 is detachably connected to the gabion boxes 2.

[0046] Specifically, in order to prevent the stones in the gabion box 2 from being washed out of the gabion box 2 during the scouring process of river water, a mesh cover 10 is provided on the opening of each gabion box 2, and the mesh specifications and materials of the mesh cover 10 are consistent with the mesh size and material of the gabion box 2, thereby ensuring the consistent performance of the entire gabion box 2.

[0047] The mesh cover 10 and the gabion box 2 can be fixed together by fixing clips or binding wires or screws, buckles, etc. Therefore, after the gabion box 2 is filled with stones, the mesh cover 10 can be directly tied to the gabion box 2.

[0048] Example 6

[0049] This embodiment is an improvement made on the basis of the embodiment 1, the difference being that a sand cushion layer 6 is laid on the bottom of the gabion box 2, and the thickness of the sand cushion layer 6 is 6-10 cm.

[0050] Specifically, in order to prevent the gabion cage 2 from moving or overturning when it is washed by river water, Figure 1 As shown, a layer of sand cushion 6 is laid at the bottom of the gabion box 2. And laying the sand cushion 6 can also increase the friction between the bottom of the gabion box 2 and the slope, improve the stability of the gabion box 2, make it more firm and not easy to slide when moving or stacking, and further improve the overall strength of the slope protection.

[0051] In addition, the sand cushion layer 6 can also effectively guide water flow, reduce water accumulation, and prevent water accumulation from causing damage to the slope protection structure. The thickness of the sand cushion layer 6 is generally 6-10 cm. The thickness of the sand cushion layer 6 in this application is 8 cm. This is because when the thickness is less than 6 cm, the sand cushion layer 6 cannot provide sufficient support for the gabion box 2, and when the thickness is greater than 10 cm, it may cause the slope protection structure to be unstable or even ruptured. Therefore, the thickness of the sand cushion layer 6 in this application is preferably 8 cm.

[0052] Example 7

[0053] This embodiment is an improvement made on the basis of the embodiment 1, and the difference lies in that it further comprises a second slope protection surface 7 on the backwater side, the second slope protection surface 7 is a soil structure, and green plants are planted on the second slope protection surface 7.

[0054] Specifically, in order to enhance the stability and durability of the river channel slope protection structure, a second slope protection surface 7 is provided on the backwater side of the first slope protection surface 1. Different from the first slope protection surface 1, the second slope protection surface 7 is a soil structure of the slope protection structure excavated from the river channel, and green plants are planted on the second slope protection surface 7 to increase the greening and ecological effects of the slope surface, and also to fix the soil and prevent soil erosion.

[0055] It should be noted that if Figure 1 As shown, a drainage ditch 9 is also provided at the bottom of the second slope protection surface 7 to drain the accumulated water on the second slope protection surface 7 to prevent the accumulated water from staying on the second slope protection surface 7 and causing the collapse of the second slope protection surface 7.

[0056] Example 8

[0057] This embodiment is an improvement made on the basis of Embodiment 1, the difference being that it further includes a slope protection top surface 8 located between the top of the first slope protection surface 1 and the top of the second slope protection surface 7, the top of the slope protection top surface 8 is flush with the top surface of the concrete top beam 5, and the slope protection top surface 8 is a gravel pavement.

[0058] Specifically, Figure 1 As shown, the slope protection structure also includes a slope protection top surface 8 located between the top of the first slope protection surface 1 and the top of the second slope protection surface 7, and the top of the slope protection top surface 8 is flush with the top surface of the concrete top beam 5, that is, the top of the entire slope protection structure is on the same horizontal plane. The slope protection top surface 8 is a gravel pavement with good water permeability and water filtration, which can effectively drain rainwater and prevent the erosion of the slope protection structure by accumulated water.

[0059] Example 9

[0060] This embodiment is an improvement made on the basis of the embodiment 2, the difference being that the stone material is a pebble, and the particle size of the pebble is d, d≥20 cm.

[0061] Specifically, the stone can be crushed stone, pebbles, boulders, conglomerates, etc. In the present application, hard, wear-resistant, and corrosion-resistant pebbles are preferred to ensure the stability and durability of the gabion box 2. Since the mesh size of the gabion box 2 in the present application is 10-12 cm, pebbles with a particle size of d≥20 cm are selected to fill the gabion box 2, and the pebbles will not drill out of the mesh.

[0062] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
