Abstract
Description
Technical Field
[0001] This utility model relates to the field of water conservancy engineering technology, specifically a combined gabion retaining wall for water conservancy river engineering. Background Technology
[0002] Water conservancy and river engineering refers to the construction of facilities such as dikes, revetments, sluices, culverts, wharves, and irrigation and drainage channels in rivers, lakes, canals, and reservoirs to control floods, improve navigation conditions, and prevent soil erosion. Gabion retaining walls are mesh structures woven from high-strength, low-carbon steel wire. They are widely used in river management, slope protection, and dam construction. Composed of multiple gabion mesh units, they possess excellent tensile and compressive strength, capable of withstanding significant water and soil pressure, ensuring structural stability and the safety and stability of the project.
[0003] Since gabion retaining walls are composed of multiple gabion mesh units, which are generally stacked directly without effective fixing, the overall stability is insufficient. Especially under the impact of river flow, there is a risk of displacement and collapse. Moreover, gabion retaining walls are generally set vertically, which does not have a good effect on dispersing water flow. The impact surface is not protected and is easily eroded by water flow. Therefore, we propose a composite gabion retaining wall for water conservancy river engineering. Utility Model Content
[0004] The purpose of this utility model is to provide a combined gabion retaining wall for water conservancy and river engineering, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a combined gabion retaining wall for water conservancy river engineering, comprising a vertical gabion area, a sloping gabion area, and a horizontal gabion area. The horizontal gabion area is located on one side of the vertical gabion area, and the sloping gabion area is located above the horizontal gabion area on one side of the vertical gabion area. Both the horizontal and vertical gabion areas are composed of gabion mesh units. Each gabion mesh unit consists of a rectangular gabion mesh body and a first stone block. A first supporting column is fixed at each corner position inside the gabion mesh unit, and the top of the first supporting column extends to the top of the gabion mesh unit and is fixed with a splicing rod. The bottom of the first supporting column extends to the bottom of the gabion mesh unit and is provided with a first splicing slot. The sloping gabion area consists of a triangular gabion mesh body and a second stone block. A second supporting column is fixed inside each triangular gabion mesh body, and the bottom of the second supporting column extends to the bottom of the triangular gabion mesh body and is provided with a second splicing slot.
[0006] Preferably, the gabion mesh units in the vertical gabion area are stacked vertically, and the gabion mesh units in the horizontal gabion area are arranged horizontally.
[0007] Preferably, the first stone is filled inside the rectangular gabion mesh, and the second stone is filled inside the triangular gabion mesh.
[0008] Preferably, the top of the rectangular gabion mesh body is provided with a first opening, and a first barrier net is fixed inside the first opening.
[0009] Preferably, each of the triangular gabion mesh bodies has a second opening at its top, and a second barrier net is fixed inside the second opening.
[0010] Preferably, a U-shaped connector is provided between the gabion mesh units, and the end of the U-shaped connector is provided with an external thread.
[0011] Preferably, a baffle is fitted at the end of the U-shaped connector, and a nut is fitted at the end of the U-shaped connector on one side of the baffle, and the nut engages with the external thread.
[0012] Preferably, the second support column corresponds one-to-one with the first support column inside the gabion unit.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] The gabion retaining wall consists of three parts: a vertical gabion area, a sloping gabion area, and a horizontal gabion area. The vertical and horizontal gabion areas are each composed of multiple gabion mesh units, each consisting of a rectangular gabion mesh body and a first stone block. The sloping gabion area consists of a triangular gabion mesh body and a second stone block. The gabion retaining wall can protect the riverbank through the vertical gabion area, and disperse the water flow in the river channel through the sloping and horizontal gabion areas, slowing down the speed of the water flow and reducing the impact on the riverbank and the damage caused by the water flow to the vertical gabion area. In addition, the gabion retaining wall adopts a multi-zone combination structure, which has strong impact resistance, is not easy to topple, and is not easily eroded by water flow. Since the corners inside the gabion mesh unit are fixed with first support columns, the first support columns can ensure the stability of the gabion mesh unit structure and prevent deformation.
[0015] Furthermore, when the gabion units are stacked vertically in the gabion area, the first support column inside the upper gabion unit engages with the splicing rod at the top of the first support column inside the lower gabion unit through the first splicing slot at its bottom, thus fixing the gabion units together and improving the overall integrity. When the horizontal gabion area is arranged, the splicing rod at the top of the first support column engages with the second splicing slot at the bottom of the corresponding second support column inside the sloping gabion area, thus tightly connecting the horizontal gabion area and the sloping gabion area, making it less prone to loosening or displacement.
[0016] Two gabion units are connected by using triangular gabion mesh bodies. Then, baffle plates are fitted onto the ends of U-shaped connectors, and nuts are fixed to the ends of U-shaped connectors by external threads. The nuts limit the position of the baffle plates, thus connecting the gabion units in pairs. Vertical gabion areas can also be connected to sloping gabion areas, and sloping gabion areas can be connected to horizontal gabion areas in the same way, so that the gabion retaining wall has good integrity and a solid and reliable structure.

[0025] Please see Figure 1-5 An embodiment of this utility model is provided: a combined gabion retaining wall for water conservancy river engineering, including a vertical gabion area 1, a sloping gabion area 3 and a horizontal gabion area 4. The horizontal gabion area 4 is located on one side of the vertical gabion area 1, and the sloping gabion area 3 is located above the horizontal gabion area 4 on one side of the vertical gabion area 1. Both the horizontal gabion area 4 and the vertical gabion area 1 are composed of gabion mesh units 2.
[0026] Specifically, the gabion retaining wall consists of three parts: a vertical gabion area 1, a sloping gabion area 3, and a horizontal gabion area 4. The vertical gabion area 1 and the horizontal gabion area 4 are each composed of multiple gabion mesh units 2. Each gabion mesh unit 2 is composed of a rectangular gabion mesh body 5 and a first stone block 6. The sloping gabion area 3 is composed of a triangular gabion mesh body 12 and a second stone block 13. The gabion retaining wall can protect the riverbank through the vertical gabion area 1, and disperse the water flow in the river channel through the sloping gabion area 3 and the horizontal gabion area 4, thereby slowing down the speed of the water flow and reducing the impact on the riverbank and the damage caused by the water flow to the vertical gabion area 1. In addition, the gabion retaining wall adopts a multi-zone combination structure, which has strong impact resistance, is not easy to collapse, and is not easily eroded by water flow.
[0027] The gabion unit 2 is composed of a rectangular gabion body 5 and a first stone block 6. A first support column 7 is fixed at each corner inside the gabion unit 2. The top of the first support column 7 extends to the top of the gabion unit 2 and is fixed with a splicing rod 8. The bottom of the first support column 7 extends to the bottom of the gabion unit 2 and is provided with a first splicing slot 9.
[0028] Specifically, since the corners inside the gabion unit 2 are all fixed with first support columns 7, the first support columns 7 can ensure the stability of the gabion unit 2 structure and prevent deformation.
[0029] Furthermore, when the gabion mesh units 2 are stacked vertically in the gabion area 1, the first support column 7 inside the upper gabion mesh unit 2 engages with the splicing rod 8 at the top of the first support column 7 inside the lower gabion mesh unit 2 through the first splicing slot 9 at its bottom end, so that the gabion mesh units 2 are spliced and fixed vertically, improving the overall integrity. When the horizontal gabion area 4 is arranged, the splicing rod 8 at the top of the first support column 7 engages with the second splicing slot 15 at the bottom of the corresponding second support column 14 inside the sloping gabion area 3, so that the horizontal gabion area 4 and the sloping gabion area 3 are tightly connected and not easy to loosen or shift.
[0030] The sloping gabion area 3 is composed of triangular gabion mesh 12 and second stones 13. The interior of each triangular gabion mesh 12 is fixed with a second support column 14, and the bottom end of the second support column 14 extends to the bottom end of the triangular gabion mesh 12 and is provided with a second splicing slot 15.
[0031] The gabion mesh units 2 in the vertical gabion area 1 are stacked vertically, and the gabion mesh units 2 in the horizontal gabion area 4 are arranged horizontally.
[0032] The first stone 6 is filled inside the rectangular gabion mesh 5, and the second stone 13 is filled inside the triangular gabion mesh 12.
[0033] The top of the rectangular gabion mesh body 5 is provided with a first opening 10, and a first barrier net 11 is fixed inside the first opening 10;
[0034] The top of each triangular gabion mesh 12 is provided with a second opening 20, and a second barrier net 21 is fixed inside the second opening 20.
[0035] A U-shaped connector 16 is provided between the gabion mesh units 2, and the end of the U-shaped connector 16 is provided with an external thread 17;
[0036] The end of the U-shaped connector 16 is fitted with a baffle 18, and the end of the U-shaped connector 16 on one side of the baffle 18 is fitted with a nut 19, and the nut 19 is threadedly engaged with the external thread 17.
[0037] Specifically, two gabion mesh units 2 are connected by using triangular gabion mesh 12, and then baffle 18 is fitted onto the end of U-shaped connector 16. Nut 19 is fixed to the end of U-shaped connector 16 by external thread 17. Nut 19 limits the baffle 18, so that gabion mesh units 2 can be connected in pairs. Vertical gabion area 1 can be connected to sloping gabion area 3 and sloping gabion area 3 can be connected to horizontal gabion area 4 in the same way, so that the gabion retaining wall has good integrity and the structure is firm and reliable.
[0038] The second support column 14 corresponds one-to-one with the first support column 7 inside the gabion unit 2.
[0039] In use, the gabion retaining wall comprises three parts: a vertical gabion area 1, a sloping gabion area 3, and a horizontal gabion area 4. Both the vertical gabion area 1 and the horizontal gabion area 4 are composed of multiple gabion mesh units 2, each consisting of a rectangular gabion mesh body 5 and a first stone block 6. The sloping gabion area 3 consists of a triangular gabion mesh body 12 and a second stone block 13. The gabion retaining wall protects the riverbank through the vertical gabion area 1 and provides additional protection through the sloping gabion area 3 and the horizontal gabion area 4. The river's water flow is dispersed, slowing down the impact and reducing the damage to the riverbank. Furthermore, the gabion retaining wall employs a multi-zone composite structure, exhibiting strong impact resistance, making it less prone to collapse and erosion. Since each corner of the gabion unit 2 is fixed with a first support column 7, the first support column 7 ensures the stability of the gabion unit 2 structure and prevents deformation. Moreover, when the gabion units 2 are stacked in the vertical gabion area 1, the first support column 7 inside the upper gabion unit 2 engages with the splicing rod 8 at the top of the first support column 7 inside the lower gabion unit 2 via its bottom first splicing slot 9, thus fixing the gabion units 2 vertically and improving overall integrity. When arranging the horizontal gabion area 4, the splicing rod 8 at the top of the first support column 7 engages with the second splicing slot 15 at the bottom of the corresponding second support column 14 inside the sloping gabion area 3, ensuring a tight connection between the horizontal gabion area 4 and the sloping gabion area 3. It is easy to loosen or shift. In addition, the gabion mesh unit 2 is connected to each other by using the triangular gabion mesh body 12, and then the baffle 18 is put on the end of the U-shaped connector 16. The nut 19 is fixed to the end of the U-shaped connector 16 by the external thread 17. The nut 19 limits the baffle 18, so that the gabion mesh unit 2 can be connected to each other. The vertical gabion area 1 can also be connected to the sloping gabion area 3 and the sloping gabion area 3 can be connected to the horizontal gabion area 4 in the same way, so that the gabion retaining wall has good integrity and the structure is firm and reliable.
[0040] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
