Description

Technical Field

[0001] This utility model relates to the field of slope reinforcement and repair technology, and in particular to a slope reinforcement and repair device based on a pumped storage power station. Background Technology

[0002] Pumped storage power stations, also known as pumped-storage hydroelectric power stations, utilize electricity generated during periods of low grid load. Water is pumped from a lower reservoir to an upper reservoir for storage, and then released back into the lower reservoir to generate electricity during peak grid load periods. Due to the operational characteristics of pumped storage power stations, they are often built in high-altitude areas to form slope structures. Therefore, excavation and modification of the high-altitude environment are unavoidable during construction. Soil erosion and landslides are major concerns. Furthermore, the frequent water level changes caused by pumping and releasing water undoubtedly exacerbate the potential threat of landslides, and may even lead to safety accidents such as dam collapses.

[0003] Therefore, slope reinforcement and repair devices are generally used to improve the slope structure of pumped storage power stations. According to the utility model patent with Chinese patent publication number CN11847439A, a structure for ecological restoration of pumped storage power station slopes in arid areas is disclosed. It is achieved by setting up a water storage tank on the slope to prevent rainwater from eroding the slope soil in large quantities, and laying a retaining frame in the area below the water storage tank. The retaining frame has a water storage cavity and a seepage hole with water storage and seepage structure, which facilitates the greening effect inside the retaining frame. However, the ecological restoration structure of this slope uses a water storage chamber as a water storage structure inside the retainer. At the same time, the water storage chamber is connected to a water storage pool through a permeable pipe. This means that the water storage chamber is kept in a water-soaked and softened state for a long time. This will not only affect the respiration of the grass roots inside the retainer, but also reduce the connection between the retainer and the soil below, which will increase the risk of landslides. Utility Model Content

[0010] The planting board consists of a planting board frame and a fine mesh layer fixed inside the frame. A sandy substrate layer is provided above the fine mesh layer, and grass structures are planted on top of the sandy substrate layer.

[0011] A water collection mechanism is provided between two adjacent planting boards. The water collection mechanism includes a pipe joint and several drain pipes.

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0027] This utility model provides a slope reinforcement and repair device based on a pumped storage power station. Several reinforcement and repair mechanisms 2 are laid on the slope 1 of the power station. Anchoring mechanisms 3 are connected to the four corners of the reinforcement and repair mechanisms 2. The lower end of the anchoring mechanism 3 is anchored into the slope 1. A water collection mechanism 4 is provided inside the reinforcement and repair mechanism 2. The water collection mechanism 4 is connected to a spraying mechanism 5.

[0028] A soil stabilizing mesh 6 is laid under the reinforcement and repair mechanism 2, and the four corners of the soil stabilizing mesh 6 are fixedly connected to the anchoring mechanism 3.

[0029] The reinforcement and repair mechanism 2 includes a frame 21, a grid frame 24 is installed inside the frame 21, and a number of installation slots 8 are provided inside the grid frame 24, with a planting board 26 installed in each installation slot 8.

[0030] The anchoring mechanism 3 includes an anchoring rod, which includes a first anchoring section 31 and a second anchoring section 32. A partition plate 33 is provided between the first anchoring section 31 and the second anchoring section 32. The second anchoring section 32 is anchored into the slope 1. The first anchoring section 31 is located inside the frame 21. A first grouting port 71 is provided on the shell of the first anchoring section 31, and a second grouting port 72 is provided on the frame 21. The first grouting port 71 and the second grouting port 72 are connected. A gravel layer is laid on the slope of the energy storage power station 1. A mortar layer is injected between the frame 21 and the gravel layer through the first grouting port 71 and the second grouting port 72.

[0031] The installation groove 8 is equipped with a grouting groove 7 located below it. The grouting groove 7 is connected to the second grouting port 72. A precast concrete slab 25 is installed in the grouting groove 7. The precast concrete slab 25 is located on the mortar layer. The planting board 26 is located on the precast concrete slab 25. The mortar layer and the precast concrete slab 25 provide a sealing and water-blocking effect for the soil layer below, and improve the installation stability between the precast concrete slab 25 and the gravel layer, and between the gravel layer and the slope soil layer, thereby further improving the reinforcement effect on the slope soil.

[0032] The planting board 26 consists of a planting board frame and a fine mesh layer 9 fixed inside the frame. A sandy substrate layer 10 is provided above the fine mesh layer 9, and a grass structure is planted on top of the sandy substrate layer 10. The fine mesh layer 9 can intercept the sandy substrate layer 10 while filtering out excess water, maintaining the respiration of the plant roots. Combined with the grass structure, ecological restoration is achieved, and soil and water loss is reduced.

[0033] In this embodiment, the mesh diameter of the fine mesh layer 9 is 2mm.

[0034] A water collection mechanism 4 is provided between two adjacent planting boards 26. The water collection mechanism 4 includes a pipe joint 42 and several drainage pipes 41.

Several water storage chambers 13 are provided in the frame 21. The drainage pipes 41 are connected to their adjacent water storage chambers 13 to store excess water into the water storage tank, reducing the risk of landslides caused by soil softening due to water accumulation.

[0035] In this embodiment, as Figure 6 As shown, the grid frame 24 has four mounting slots 8 arranged in a circular array, thus forming four cross-shaped pipe grooves 11 within the grid frame 24. Each pipe groove 11 houses a drain pipe 41. A pipe joint 42, a four-way joint, is located at the center of the grid frame 24. The four-way joint is sealed to the outside of the four drain pipes 41 by a sealing ring. Figure 3 As shown, except for the side facing the top of the slope 1, the frame 21 has a water storage chamber 13 on the other three sides. Due to the slope inclination, excess water in the installation groove 8 will flow into the water storage chamber 13 through the drain pipe 41 for collection, preventing water accumulation inside the grid frame 24 from affecting the respiration of plant roots and the problem of excessive soil wetting.

[0036] A filter screen structure can be installed in the drain outlet 12 to prevent sand and soil from entering the pipe trench 11.

[0037] The spraying mechanism 5 includes a spraying frame and spraying pipe 51, a booster pump 52, a water storage chamber 13, a booster pump 52, and a spraying pipe 51 connected by a water inlet pipe 14.

[0038] The anchoring mechanism 3 also includes an isolation tube 34 sleeved inside the anchoring rod body and a barbed rod 35 hinged to the lower end of the anchoring rod body. An adjusting screw 36 is internally threaded into the isolation tube 34. A lifting ring 37 is connected to the lower end of the adjusting screw 36.

A first lifting groove is provided on the anchoring rod body for the connecting rod structure 38 and the barbed rod 35 to move. A second lifting groove is provided on the isolation tube 34 for the lifting ring 37 to move. The lower end of the anchoring rod body is a pointed tip.

[0039] In this embodiment, four barbed rods 35 are hinged around the lower end of the anchor rod body.

The second anchoring section 32 of the anchoring rod is anchored into the slope. The opening angle of the barb rod 35 can be adjusted by adjusting the screw 36. b. A mortar layer is injected into the frame 21 through the first grouting port 71 on the first anchoring section 31 of the anchoring rod and the second grouting port 72 on the frame 21. The mortar layer, the gravel layer and the anchoring mechanism 3 work together to improve the stability of the frame 21 and provide preliminary waterproofing to the slope below. c. Install a grid frame 24 inside the frame 21. A precast concrete slab layer is installed in the grouting groove 71 of the grid frame 24 to further improve the waterproofing ability of the slope below. A planting board 26 is installed in the installation groove 8 of the grid frame 24. The planting board 26 consists of a planting board frame and a fine mesh layer 9 fixed inside the frame. A sandy substrate layer 10 is provided above the fine mesh layer 9. Grass structures are planted on top of the sandy substrate layer 10. d. Connect the drainage hole 12, drainage pipe 41, and pipe joint 42. Excess water in the installation groove 8 flows into the water storage chamber 13 and can reach the sprinkler pipe 51 through the water pipe 14 and booster pump 52. During drought, the water is sprayed onto the planting board 26 through the sprinkler head 15 to achieve self-sufficient irrigation.

[0041] The structures in steps c to d can all be prefabricated and assembled in advance.
