[0002] In the field of water conservancy engineering, the reinforcement of the back slope of the dam is of utmost importance. The back slope of the dam is often eroded by rainwater, causing soil loss, which threatens the stability of the dam, affects the operation of the water conservancy project and the safety of the surrounding area. Therefore, it is necessary to reinforce the back slope of the dam to ensure the stability of the dam.

[0003] The local structure of the dam's back slope is prone to loosening due to long-term water erosion, geological changes, and the decline in material properties over time, increasing the risk of collapse and threatening the safe operation of the water conservancy project. At the same time, replacing the local reinforcement structure is quite difficult. Therefore, there is an urgent need to develop a reinforcement structure for the dam's back slope to solve these practical problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a reinforcement structure for the back slope of a dam, which solves the problem that the local structure of the back slope of a dam is prone to loosening due to long-term water erosion, geological changes, and the decline in material properties over time, increasing the risk of collapse and threatening the safe operation of water conservancy projects.

[0005] To achieve the above objectives, this utility model provides a dam back slope reinforcement structure through the following technical solution, including a frame, a metal perforated plate fixedly connected to the inner side of the frame, and a reinforcement component provided on one side of the frame.

[0006] It also includes a local reinforcement mechanism, which includes a docking assembly set at the top of the frame. Multiple sets of movable seats are inserted and installed inside the docking assembly.

Screws are threaded on both sides of the top of the movable seats. A hollow frame for local contact reinforcement of the metal perforated plate is rotatably installed at the bottom end of the screw. Reinforcing ribs are cross-installed on the inner side of the hollow frame.

[0007] Preferably, the docking assembly includes docking seats equidistantly arranged on both sides of the top of the frame, and a locking member corresponding to the movable seat is threadedly installed on the top of the docking seat, and the locking member passes through the interior of the docking seat and is threadedly connected to the movable seat.

[0012] This utility model provides a reinforcement structure for the back slope of a dam. Compared with the prior art, it has the following advantages.

[0013] 1. The slope reinforcement frame is anchored to the slope by rotating the positioning anchor bolts. The rotating screw drives the hollow frame to contact the metal perforated plate, and the reinforcing ribs enhance the stability, realizing the local reinforcement of the back slope of the dam and solving the problem of local loosening affecting the overall stability.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] First implementation method:

[0021] refer to Figs. 1-3 A dam back slope reinforcement structure includes a frame 1, a metal perforated plate 101 fixed to the inner side of the frame 1, and a reinforcement component is also provided on one side of the frame 1.

[0022] It also includes a local reinforcement mechanism 2, which includes a docking assembly set on the top of the frame 1. Multiple sets of movable seats 201 are inserted and installed inside the docking assembly. Positioning anchors 202 for reinforcing the connection between the frame 1 and the slope are threaded on the outside of the movable seats 201. Screws 203 are threaded on both sides of the top of the movable seats 201. A hollow frame 204 for locally reinforcing the metal perforated plate 101 is rotatably installed at the bottom of the screws 203. Reinforcing ribs 205 are cross-installed on the inner side of the hollow frame 204.

[0023] The docking assembly includes docking seats 206 equidistantly arranged on both sides of the top of the frame 1. A locking member 207 corresponding to the movable seat 201 is threadedly installed on the top of the docking seat 206, and the locking member 207 passes through the interior of the docking seat 206 and is threadedly connected to the movable seat 201.

[0024] The reinforcement component includes a fixing plate 3 disposed on one side of the frame 1. A shaft bracket 301 is fixedly connected to the top side of the fixing plate 3. A connector 302 is rotatably installed inside the shaft bracket 301, and one side of the connector 302 is fixedly connected to the top side of the frame 1. The hollow frame 204 is rectangular in shape and is made of aluminum alloy.

[0025] The fixing plate 3 is connected to the ground on one side of the slope by anchor bolts, and is connected to the top side of the frame 1 by the connector 302 rotatably installed inside the shaft frame 301, which further strengthens the frame 1.

[0026] Rotating frame 1 causes frame 1 to move in an arc around the axis of shaft 301 to one side of the slope and be fixed. Frame 1 and metal porous plate 101 serve as the basic support structure and are fixed to the slope for reinforcement by anchor bolts.

[0027] When installing the movable seat 201, the operator pushes the movable seat 201 so that it is inserted into the docking seat 206, and rotates the locking piece 207 to fix the moving position of the movable seat 201.

[0028] By rotating the positioning anchor bolt 202, the positioning anchor bolt 202 extends into the slope outside the frame 1 for anchoring, thereby strengthening the connection stability between the frame 1 and the slope. Then, by rotating the screw 203, the screw 203 drives the hollow frame 204, which is rotated at the bottom, to move, so that the hollow frame 204 abuts against the surface of the metal porous plate 101 for regional abutment reinforcement. Furthermore, the stability of the hollow frame 204 is increased by the reinforcing ribs 205 installed crosswise on the inner side of the hollow frame 204, thus realizing the local reinforcement function of the back slope of the dam and solving the problem that the local structure of the back slope of the dam is easy to loosen, affecting the overall stability.

[0029] When disassembling the movable seat 201 and the hollow frame 204, the operator first rotates the positioning anchor bolt 202 in the opposite direction so that it is unscrewed from the inside of the slope outside the frame 1, thereby releasing the anchoring connection between the frame 1 and the slope.

[0030] Next, rotate the locking member 207 in the opposite direction to disengage it from the movable seat 201, thereby releasing the fixation of the movable seat 201. Then, pull the movable seat 201 out from the docking seat 206 to complete the disassembly of the movable seat 201, so that the hollow frame 204 is no longer in contact with the surface of the metal perforated plate 101, thus completing the disassembly process. This disassembly design facilitates the replacement and maintenance of damaged or aged parts, ensuring the long-term stable operation of the entire reinforced structure.

[0031] Second implementation method:

[0032] The slope is easily eroded by rainwater, which can lead to a decrease in the stability of the back slope of the dam and damage to the surrounding ecological environment.

[0033] refer to Fig. 3 In the second embodiment of this utility model, a waterproof soil loss component 4 is also provided on the top of the fixed plate 3. The waterproof soil loss component 4 includes a baffle 401 provided on one side of the top of the fixed plate 3, and the top section of the baffle 401 is V-shaped. An installation groove is provided inside the baffle 401, and a metal mesh plate 402 is fixedly connected inside it. Side plates 403 are also provided on both sides of the baffle 401, and the bottom of the side plates 403 is fixedly connected to the top of the fixed plate 3.

[0034] A protective plate 404 is also provided on the top of the fixed plate 3. The protective plate 404 is located on the side of the top of the fixed plate 3 away from the baffle 401, and its top cross section is an inverted V shape.

[0035] The protective plate 404 intercepts and diverts water and debris flowing down the slope. When water and debris flow down the slope, the protective plate 404, due to its inverted V-shaped top structure, can guide the water flow to both sides, preventing the water flow from concentrating and impacting the structure below.

[0036] The V-shaped baffle 401, together with the internally fixed metal mesh plate 402, separates the mud and water carried by the water flow. When the water flows through the metal mesh plate 402, the mud particles are blocked on the metal mesh plate 402, while the water continues to flow downward through the mesh.

[0037] The side plates 403 on both sides of the baffle 401 divert water and soil, blocking the separated soil within a certain range to prevent it from sliding and spreading randomly. At the same time, they guide the water flow in a specific direction. The protective plate 404 at the top of the inverted V-shape can guide the water flow and prevent the water flow from directly impacting the metal mesh plate 402 inside the V-shaped baffle 401. This effectively solves the problem of deformation and damage to the metal mesh plate 402 caused by excessive local stress due to direct impact from the water flow. It achieves an effective protection function against soil erosion on the slope and avoids the problem of decreased stability of the back slope of the dam and damage to the surrounding ecological environment caused by soil erosion.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
