Description

Technical Field

[0001] The utility model relates to the technical field of bank protection structures, in particular to a highly permeable ecological bank protection structure applied to rivers. Background Art

[0002] In both urban and rural areas, many river management projects face limited riverbank space due to factors such as planning redline restrictions. Traditional river management methods typically use masonry or concrete retaining walls to enhance riverbank stability. While these methods effectively ensure riverbank safety and durability, they often overlook the importance of environmental protection and ecological restoration, resulting in a degree of ecological damage.

[0003] In recent years, with rising environmental awareness and technological advancements, eco-friendly river management technologies have gradually gained attention. For example, Chinese utility model patent CN219343047U proposes a riverbed mat for erosion prevention and ecological protection. This solution utilizes a Reno mat (a grid-like structure made of metal mesh) filled with stone. This not only effectively resists erosion and protects the riverbed and banks from damage, but also provides space for aquatic plants to grow, promoting natural interaction between the water and the riverbank. Furthermore, by replacing traditional concrete structures with gabion retaining walls, negative environmental impacts can be significantly reduced while maintaining low construction costs, thereby improving the project's economic and ecological benefits.

[0004] However, existing ecological revetment technologies still face several challenges.

[0005] On the one hand, the Binge gabion retaining wall relies on a cage-like structure woven from metal mesh to fix the filling stones inside. However, under the action of long-term water flow impact, the internal filling stones repeatedly move and impact the cage wall, causing the cage structure to deform, affecting its long-term stability and service life.

[0006] On the other hand, when multiple gabion retaining walls are stacked vertically, they primarily support each other through their own weight, lacking an effective connection mechanism. This can cause the entire structure to lose balance or even collapse when subjected to strong water flow, threatening the safety of the river management project.

[0007] In view of this, the inventor specially designed a highly permeable ecological bank protection structure for use in rivers, which led to the creation of this case. Utility Model Content

The intermediate connecting section is arranged in the cage-like structure and is arranged in contact with its side wall. The upper connecting section is arranged at the inner bottom of the upper adjacent cage-like structure, and the lower connecting section is arranged at the inner top of the next adjacent cage-like structure.

[0016] Preferably, the upper connecting section and the lower connecting section are both provided with a "U"-shaped buckle section on one side away from the middle connecting section, and the two buckle sections on the same structural connecting piece are arranged in a direction approaching each other.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Example

[0034] See also Figures 1 to 7 , which is a highly permeable ecological bank protection structure for river channels as a preferred embodiment of the present utility model, includes foundation pits (not shown in the figure) excavated along the existing lines on both sides of the river channel 90, each of which is provided with a buried stone concrete foundation 10 and the remaining portion is backfilled with rammed earth 11, and a gabion retaining wall 20 is provided at the upper end of the buried stone concrete foundation 10, and the gabion retaining wall 20 is composed of a plurality of cage-like structures 21 filled with stone.

[0035] A structural support member 30 is provided in each cage-like structure 21 for supporting the cage-like structure 21 ; and a structural connector 40 is provided between adjacent cage-like structures 21 for connecting adjacent cage-like structures 21 to enhance overall stability.

[0036] Specifically, in this embodiment, the gabion retaining wall has a height of 3.7m (including the foundation), a vertical back wall, and three layers of cage-like structures 21 stacked in a stepped pattern. Each layer of cage-like structures 21 is 1.0m thick from top to bottom, with a top width of 1.0m. Each layer of cage-like structures 21 is staggered 0.5m apart. A filter geotextile 50 (specified at 400g / m²) is installed at the toe and back of the wall. The cage-like structures 21 are filled with stone (not shown) with a diameter between 1.5 and 2 times the mesh diameter, preferably between 100 and 300mm. Pebbles, slabs, or blocks can be used, with a strength grade of MU30 and a specific gravity of no less than 2.5t / m³. The rammed earth 11 used for backfilling the wall has a compaction degree of no less than 0.92. The foundation of the gabion retaining wall 20 is buried 0.5m deep and uses a C20 buried stone concrete foundation 10. Settlement joints (not shown) are provided every 15m. A 20cm thick C20 concrete capping 12 is set on the top of the wall. A leisure pedestrian walkway 70 or a rural cement passage is set behind the wall to connect.

[0037] Preferably, specifically, Figure 2 、 3As shown, the structural support member 30 is L-shaped and includes a horizontal section 31 at the bottom and a vertical section 32 along the vertical upper edge of one end of the horizontal section 31. The horizontal section 31 is pressed between the bottom of the stone and the bottom of the cage-like structure 21, and the vertical section 32 is attached to the inner wall of the cage-like structure 21.

[0038] Preferably, Figure 3 、 4 As shown, the vertical section 32 is attached to the inner wall of the cage structure 21 on the side close to the center of the river channel 90 .

[0039] Specifically, the horizontal section 31 is placed at the inner bottom of the cage-like structure 21. The stones used for filling in the cage-like structure 21 press the horizontal section 31 steadily. The gravity of the stones pressing down is used to keep the horizontal section 31 stable, so that the vertical section 32 fits the inner wall of the cage-like structure 21 and provides stable support for the inner wall of the cage-like structure 21.

[0040] Preferably, Figure 5 As shown, the structural support member 30 has an arc-shaped bending transition section 33 at the connection position between the vertical section 32 and the horizontal section 31 .

[0041] Preferably, Figure 6 As shown, the structural connecting member 40 is in the shape of a Chinese character "匚", including an upper connecting section 41 located at the upper end and extending horizontally, a lower connecting section 43 located at the lower end and parallel to the upper connecting section 41, and an intermediate connecting section 42 connected between the upper connecting section 41 and the lower connecting section 43. The intermediate connecting section 42 is arranged in the cage-like structure 21 and is arranged in contact with its side wall. The upper connecting section 41 is arranged at the inner bottom of the upper adjacent cage-like structure 21, and the lower connecting section 43 is arranged at the inner top of the next adjacent cage-like structure 21.

[0042] Thus, the upper connecting section 41 and the lower connecting section 43 hook the two upper and lower adjacent cage-like structures 21 , so that the upper and lower adjacent cage-like structures 21 maintain a stable connection, further enhancing the firmness of the connection.

[0043] Preferably, Figure 6 As shown, the upper connecting section 41 and the lower connecting section 43 are both provided with a "U"-shaped buckle section 44 on one side away from the middle connecting section 42, and the two buckle sections located on the same structural connector 40 are arranged in a direction close to each other.

[0044] The buckle section 44 can reversely hook the hollow portion of the wire mesh constituting the cage-like structure 21 through its U-shaped bent structure, further enhancing the connection stability between the structural connector 40 and the cage-like structure 21 .

[0045] Preferably, Figure 6As shown, the structural connectors 40 in the adjacent cage structures 21 are distributed in staggered manner, and through the staggered distribution of the structural connectors 40, the connection positions between the adjacent cage structures 21 can be more dispersed and averaged, so that the overall connection between the adjacent cage structures 21 is more stable.

[0046] Preferably, the Bing stone cage retaining wall 20 located on the same side of the river 90 is composed of three layers of cage structures 21 stacked in a ladder shape, and the cage structure 21 located at the lowermost layer has the longest bottom, and the cage structures 21 located at the upper layers are sequentially inwardly contracted to form a ladder shape.

[0047] Preferably, the ladder-shaped structure composed of the cage structures 21 is planted with aquatic plants 60 near the side of the river 90, the filter geotextile 50 is laid between the cage structures 21 and the revetment and the buried concrete foundation 10 on both sides of the river 90, and the pedestrian walkway 70 is arranged at the top of the revetment on both sides of the river 90 and is distributed along the river 90.

[0048] In the embodiment, each panel of the cage structure 21 is a hexagonal double-twisted steel wire mesh woven by low-carbon steel wires, and the left and right sides of the hexagonal panel are double-twisted to form a mesh surface steel wire. Embodiment

[0049] Please refer to Figure 7 The utility model discloses a kind of strong water-permeable ecological revetment structures applied to river, and the difference from embodiment one is that structure support 30 is rectangular, and is attached along the inner side wall of cage structure 21.

[0050] Compared with the L-shaped structure support 30, the rectangular structure support 30 can fully support each inner side wall of the cage structure 21, further improving the support effect of the structure support 30 on the whole cage structure 21.

[0051] The utility model has the advantages of the following:

[0052] The utility model adds structure support 30 inside each cage structure 21 constituting Bing stone cage retaining wall 20, effectively supports cage body, and significantly reduces the risk of structural deformation. At the same time, structure connector 40 is used to firmly connect adjacent cage structures 21, to ensure the stability of the whole structure, and to further strengthen the connection between each cage structure 21.

[0053] The above is an exemplary description of the present invention in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
