Description

Technical Field

[0001] The utility model relates to the field of river bank slope protection, in particular to a slope protection structure for a river channel in a water conservancy project. Background Art

[0002] The slope protection of the river channel is to protect the river bank slope from being severely scoured, which may lead to serious soil erosion and further cause the continuous collapse of the river bank. The existing types of slope protection for river channels mainly include plant slope protection, geosynthetic material protection, riprap protection, and concrete protection, etc. Among them, the concrete slope protection mainly uses concrete bricks for paving. When laying the concrete bricks, generally, the sundries on the river bank slope are first cleared, then leveling cement mortar is smeared on several surfaces, and finally the protection is laid flat on the cement mortar. The advantages of laying the cement mortar are: it can not only fix the protection bricks but also have a leveling effect. Since most of the river bank slope planes are uneven, the surface is basically flat after the cement mortar is smeared, which is also beneficial to laying the protection bricks. At the same time, the stability of the protection bricks after laying is good after leveling. However, its disadvantages are that a large amount of cement mortar is required, the cost is relatively high, and in addition, because the slope protection bricks need to be pasted on the cement mortar after leveling, the operation is relatively troublesome, which prolongs the construction period of the slope protection structure. Therefore, how to improve the laying efficiency and shorten the laying construction period on the basis of ensuring the laying firmness has become an urgent problem to be solved at present. Summary of the Utility Model

[0003] The existing laying of protection bricks generally requires a large amount of cement mortar, with a relatively high cost, and the slope needs to be leveled before laying, which is relatively troublesome to operate and prolongs the construction period of the slope protection structure. Therefore, how to improve the laying efficiency and shorten the laying construction period on the basis of ensuring the laying firmness has become the technical problem to be solved in this application. This application designs a slope protection structure for a river channel in a water conservancy project, and the specific technical solution adopted is as follows:

[0004] A slope protection structure for a river channel in a water conservancy project includes slope protection bricks. Multiple slope protection bricks are spliced in sequence to form a slope protection surface. Each slope protection brick includes:

[0005] A brick body, and inserting pins for inserting into the ground are provided on the lower surface of the brick body;

[0006] Multiple male connectors or female connectors, and multiple male connectors or female connectors are correspondingly arranged on multiple side surfaces of the brick body, and the male connectors and female connectors of two adjacent slope protection bricks are connected;

[0007] U-shaped nails, and the U-shaped nails are inserted into each connection part of two adjacent slope protection bricks.

[0008] Preferably, the female connector is a steel bar with a U-shaped cross-section. At one end away from the brick body, the female connector is provided with a first stop bar, which is located on the concave cavity side of the U-shaped steel bar and perpendicular to the upper surface of the female connector. The male connector is a steel bar with a square cross-section and can be inserted into the U-shaped concave cavity of the female connector. At one end away from the brick body, the male connector is provided with a second stop bar. After the U-shaped nail is inserted into the ground, the first stop bar and the second stop bar are located on both sides of the U-shaped nail.

[0009] Preferably, both the female connector and the male connector are steel plates with a square cross-section, and the surfaces of the male connector and the female connector that are in mutual contact are serrated surfaces.

[0010] Preferably, one end surface of the female connector or the male connector close to the brick body is provided.

[0011] Preferably, a plurality of through holes are correspondingly provided on multiple side surfaces of the brick body, and the through holes are arranged away from the female connector or the male connector. A connecting rope is connected between multiple slope protection bricks, and the connecting rope passes through at least one through hole of each slope protection brick. The head end and the terminal end of the connecting rope are fixed ends and are fixed at a position close to the shore of the river bank slope.

[0012] Preferably, the connecting rope is a steel wire rope.

[0013] Preferably, the plugging rod is a steel rod, and the lower end has a spiked part.

[0014] Preferably, at least two plugging rods are symmetrically arranged on the lower surface of each brick body.

[0021] To clearly illustrate the technical features of this solution, the present utility model will be described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0022] In addition, in the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0023] As Figures 1-4 shown, a slope protection structure for the river channel slope of a water conservancy project includes slope protection bricks 2. Multiple slope protection bricks 2 are spliced in sequence to form a slope protection surface. Each slope protection brick 2 includes a brick body 4, multiple female connectors 6 or male connectors 7, and U-shaped nails 8. Among them, the brick body 4 can be a hexagonal hollow brick body 4 or a quadrilateral hollow brick body 4. The lower surface of the brick body 4 is provided with a plugging rod 9 inserted into the ground. Here, the plugging rod 9 is a steel rod, and its hardness and strength can meet the use requirements. The plugging rod 9 is arranged perpendicular to the lower surface of the brick body 4, and the end of the plugging rod 9 has a pointed part, which is convenient for inserting into the ground of the river channel 1 slope, so as to fix the brick body 4. Of course, in order to further fix the brick body 4, multiple male and female connectors 6 are also provided between the brick body 4 and the brick body 4 (that is, between two adjacent brick bodies 4). For a single brick body 4, multiple female connectors 6 or multiple male connectors 7 are correspondingly arranged on multiple side surfaces of the brick body 4. For example, six female connectors 6 or male connectors 7 are correspondingly connected to the six side surfaces of the hexagonal hollow brick body 4. During the splicing process of the slope protection bricks 2, adjacent brick bodies 4 are connected by male and female connectors 6, and finally each connection part of the male and female connectors 6 is fixed with a U-shaped nail 8. Through the above technical solution, not only can the construction firmness of the slope protection bricks 2 be ensured, but also the use of cement mortar can be avoided. It can be directly laid on the river channel 1 slope without leveling the river channel 1 slope, improving the laying efficiency and shortening the laying cycle.

[0024] In one embodiment, as Figure 2As shown, the above-mentioned female connector 6 is a steel bar with a U-shaped cross-section. The female connector 6 is provided with a first stop bar at one end far from the brick body 4. The first stop bar is located on the concave cavity side of the U-shaped steel bar and is perpendicular to the upper surface of the female connector 6. The male connector 7 is a steel bar with a square cross-section. The male connector 7 and the female connector 6 are located on different brick bodies 4. During the process of splicing two adjacent brick bodies 4 to form a slope protection structure, the male connector 7 can be inserted into the U-shaped concave cavity of the female connector 6. The male connector 7 is provided with a second stop bar at one end far from the brick body 4. After the U-shaped nail 8 is inserted into the ground, the first stop bar and the second stop bar are located on both sides of the U-shaped nail 8. The stop bars on the female and male connectors 6 located on one side of the U-shaped nail 8 can prevent the female and male connectors 6 from separating. Secondly, the U-shaped nail 8 can also be inserted into the ground to fix the female and male connectors 6 on the slope surface, and then fix the edge of the brick body 4. By connecting the female and male connectors 6 and cooperating with the U-shaped nail 8 and the plugging rod 9 to fix the brick body 4 at the same time, the slope protection construction efficiency of the brick body 4 can be improved on the basis of ensuring the firmness of the brick body 4, and the construction period can be shortened.

[0025] In one embodiment, as Figure 4 shown, the above-mentioned female connector 6 and male connector 7 are both steel plates with a square cross-section. The surfaces of the male connector 7 and the female connector 6 that are in contact with each other are serrated surfaces. When multiple slope protection bricks 2 are spliced to form a slope protection structure, the serrated surfaces can prevent the female and male connectors 6 from separating. Then, the U-shaped nail 8 is inserted into the ground to press the female and male connectors 6 tightly to fix the brick body 4.

[0026] Furthermore, in order to avoid the U-shaped nail 8 generating a large shearing force on the female and male connectors 6 when pressing them, one end surface of the female connector 6 or the male connector 7 close to the brick body 4 is set. When laying the slope protection brick 2, the female connector 6 or the male connector 7 is laid on the side close to the ground. Since it is in close contact with the ground itself, when the U-shaped nail 8 presses the female and male connectors 6, the female and male connectors 6 will not bear a large shearing force due to being suspended.

[0027] Furthermore, a plurality of through holes 5 are correspondingly provided on multiple side surfaces of the brick body 4. The through holes 5 are arranged far from the female connector 6 or the male connector 7 (that is, the through holes 5 and the female connector 6 or the male connector 7 are respectively arranged close to the two side surfaces of the brick body 4). A connecting rope 3 is connected between multiple slope protection bricks 2. When multiple slope protection bricks 2 are spliced to form a slope protection structure for the river channel 1, the connecting rope 3 passes through at least one through hole 5 of each slope protection brick 2. According to the actual rope threading situation, in this application, the connecting rope 3 can pass through each through hole 5 of each brick body 4 to connect the slope protection bricks 2. After connection, the head end and the terminal end of the connecting rope 3 are fixed ends and are fixed at a position on the slope of the river channel 1 close to the shore. The head end and the terminal end are set at a position close to the shore in order to make the connecting rope 3 have an upward pulling force on the whole slope protection brick 2, so as to avoid the whole slope protection brick 2 moving downward and changing its position under the long-term water and soil erosion, affecting the overall stability of the slope of the river channel 1.

[0028] Furthermore, in order to ensure the strength and durability of the connecting rope 3, the above-mentioned connecting rope 3 is made of steel wire rope.

[0029] Furthermore, at least two plugging pins 9 are symmetrically arranged on the lower surface of each brick body 4. The number of plugging pins 9 is set differently according to the shape of the brick body 4. If the area of the brick body 4 is large, a larger number of plugging pins 9 can be set accordingly. If the area of the brick body 4 is small, the number of plugging pins 9 can be reduced.

[0030] The above specific embodiments cannot be used as a limitation to the protection scope of the present utility model. For those skilled in the art of this technology, any alternative improvement or transformation made to the embodiments of the present utility model falls within the protection scope of the present utility model.

[0031] Those not detailed in the present utility model are all well-known technologies to those skilled in the art of this technology.
