Description

Technical Field

[0001] This application relates to the field of dam slope reinforcement technology, and in particular to a dam slope reinforcement device for pumped storage power stations. Background Technology

[0002] As an important facility for power grid peak regulation, pumped storage power stations are subjected to hydraulic scouring and seepage pressure caused by periodic water level changes in their dam bodies over a long period of time, so it is necessary to reinforce the dam slopes of pumped storage power stations.

[0003] In the prior art, after the slope of the pumped storage power station dam is reinforced, it is not possible to effectively intercept impurities and stones sliding down the slope surface under extreme weather conditions. As a result, impurities and larger stones enter the drainage ditch and cause blockages. Furthermore, the rapid rainwater can directly spread to the opposite bank, causing the opposite bank of the dam to be eroded. Therefore, this application proposes a pumped storage power station dam slope reinforcement device. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a pumped storage power station dam slope reinforcement device, which overcomes the shortcomings of the prior art and aims to solve the problems in the background art.

[0005] To achieve the above objectives, this application adopts the following technical solution: a pumped storage power station dam slope reinforcement device, comprising a dam slope body, the outer wall of which is equipped with multiple reinforcing ribs, the inner wall of which is provided with multiple square grooves, the inner walls of which are each reinforced with a reinforcing plate, the outer wall of which is poured with a concrete surface layer, an extension layer installed on the outer side of which is provided, the bottom of which is connected to a baffle plate via a hinge, the inner wall of which is provided with multiple drainage grooves, a fixing block one pre-embedded in the inner wall of which is provided with the concrete surface layer, a fixing block two installed on one side of which is provided with the baffle plate, and the two ends of a connecting rod inserted into the inner walls of the fixing block one and the fixing block two.

[0006] In a preferred embodiment, the inner wall of the reinforcing plate is provided with a plurality of casting holes, and the plurality of casting holes are connected to the inner wall of the square groove, and the inner wall of the casting holes is filled with mortar.

[0007] By adopting the above technical solution, mortar can be poured into the interior of the square trench through the pouring hole, and the reinforcing plate can be positioned using the mortar to ensure that the reinforcing plate can be stably set inside the square trench. At the same time, it is convenient to lay the concrete surface layer in subsequent stages, and the concrete surface layer can be laid in sections on the surface of the dam slope body with the reinforcing plate as the fulcrum.

[0008] In a preferred embodiment, the outer edges of the reinforcing plate and the reinforcing rib are provided with a galvanized layer, and both the reinforcing plate and the reinforcing rib cover the interior of the concrete surface layer.

[0009] By adopting the above technical solutions, a protective layer can be formed on the outside of the reinforcing ribs and reinforcing plates, thereby ensuring that the reinforcing plates and reinforcing ribs will not be easily corroded. Furthermore, the reinforcing plates and reinforcing ribs are solidified inside by the concrete surface layer, thereby increasing the strength of the concrete surface layer. This can also be used to increase the strength of the surface layer of the dam slope itself, ensuring that it will not easily collapse in the event of extreme weather.

[0010] In a preferred embodiment, a planting layer is provided on the top of the dam slope body, and multiple planting holes are provided through the inner wall of the planting layer. A covering layer is laid on the top of the dam slope body.

[0011] By adopting the above technical solution, grass seeds can be sown inside the planting holes. After the grass seeds germinate, the roots of the plants can grow into the interior of the dam slope and penetrate the cover layer to form a vegetation layer, increasing the aesthetics of the top of the dam slope and preventing landslides, thus increasing the overall coherence of the soil.

[0012] In a preferred embodiment, a prefabricated side plate is installed on the outer wall of the dam slope body, and a screw rod is inserted through the inner wall of the prefabricated side plate and the dam slope body. A nut is threadedly connected to the outer edge of the screw rod, and the nut abuts against the outer wall of the prefabricated side plate.

[0013] By adopting the above technical solution, screws and nuts can be used to position the precast side panels, ensuring that the precast side panels can be stably attached to the outer wall of the dam slope body, and intercepting the sides when laying the concrete surface layer, ensuring that the concrete will not fall to one side of the ground.

[0014] In a preferred embodiment, the bottom of the extended layer is provided with a drainage channel, and the baffle is disposed above the middle of the drainage channel.

[0015] By adopting the above technical solution, water flowing down the concrete surface can be directly discharged into the drainage ditch and enter the drainage system. When the baffle is set vertically, it can intercept impurities and stones sliding down the concrete surface during extreme weather, ensuring that they do not fall directly into the drainage ditch. At the same time, it prevents water from flowing too fast and being discharged directly to the other side of the drainage ditch, causing rainwater to spread.

[0016] The beneficial effects of this application are:

[0017] This pumped storage power station dam slope reinforcement device, when vertically installed with baffles, can intercept impurities and stones sliding down the concrete surface during extreme weather, ensuring they do not fall directly into the drainage ditch. It also prevents water from flowing too fast and being discharged directly to the opposite bank of the drainage ditch, thus preventing rainwater from spreading. Furthermore, the use of reinforcing ribs and reinforcing plates can increase the strength of the concrete surface adhering to the dam slope itself.

[0018] This pumped storage power station dam slope reinforcement device involves sowing grass seeds into the planting holes. After the seeds germinate, the plant roots can grow into the interior of the dam slope and penetrate the cover layer to form a vegetation layer. This increases the aesthetics of the top of the dam slope, prevents landslides, increases the overall coherence of the soil, and further improves the strength of the top of the dam slope.

[0025] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0026] Reference Figure 1-5 A pumped storage power station dam slope reinforcement device includes a dam slope body 1, with multiple reinforcing ribs 2 installed on the outer wall of the dam slope body 1, multiple square grooves 3 opened on the inner wall of the dam slope body 1, and reinforcing plates 4 inserted into the inner walls of the multiple square grooves 3, a concrete surface layer 6 poured on the outer wall of the dam slope body 1, an extension layer 10 installed on the outer side of the dam slope body 1, a baffle 12 rotatably connected to the bottom of the extension layer 10 via a hinge 11, multiple drainage grooves 13 opened on the inner wall of the baffle 12, a fixing block 14 pre-embedded in the inner wall of the concrete surface layer 6, a fixing block 25 installed on one side of the baffle 12, and the two ends of a connecting rod 16 inserted into the inner walls of the fixing block 14 and the fixing block 2 15.

[0027] See Figure 3and Figure 4 The inner wall of the reinforcing plate 4 has multiple pouring holes 5, and the multiple pouring holes 5 are connected to the inner wall of the square trench 3. The inner wall of the pouring holes 5 is filled with mortar, so that the mortar can be poured into the interior of the square trench 3 through the pouring holes 5. The mortar can then be used to position the reinforcing plate 4, ensuring that the reinforcing plate 4 can be stably set inside the square trench 3. At the same time, it is convenient to lay the concrete surface layer 6 in the future. The concrete surface layer 6 can be laid in sections on the surface of the dam slope body 1 with the reinforcing plate 4 as the fulcrum.

[0028] See Figure 3 and Figure 4 The outer edges of the reinforcing plate 4 and the reinforcing rib 2 are provided with a galvanized layer. The reinforcing plate 4 and the reinforcing rib 2 are both covered inside the concrete surface layer 6, so that a protective layer can be formed on the outside of the reinforcing rib 2 and the reinforcing plate 4, thereby ensuring that the reinforcing plate 4 and the reinforcing rib 2 will not be easily corroded. Furthermore, the reinforcing plate 4 and the reinforcing rib 2 are solidified inside by the concrete surface layer 6, thereby increasing the strength of the concrete surface layer 6. At the same time, it can be used to increase the strength of the surface layer of the dam slope body 1, ensuring that it will not easily collapse in the event of extreme weather.

[0029] See Figure 4 The top of the dam slope body 1 is provided with a planting layer 7, and multiple planting holes 8 are opened through the inner wall of the planting layer 7. The top of the dam slope body 1 is covered with a covering layer 9, which allows grass seeds to be sown into the planting holes 8. After the grass seeds germinate, the roots of the plants can grow into the interior of the dam slope body 1 and then penetrate the covering layer 9 to form a vegetation layer, which increases the aesthetics of the top of the dam slope body 1 and prevents landslides, thus increasing the overall coherence of the soil.

[0030] See Figure 1 A precast side plate 17 is installed on the outer wall of the dam slope body 1. A screw 18 is inserted through the precast side plate 17 and the inner wall of the dam slope body 1. A nut 19 is threaded on the outer edge of the screw 18. The nut 19 abuts against the outer wall of the precast side plate 17, so that the screw 18 and the nut 19 can be used to position the precast side plate 17, ensuring that the precast side plate 17 can be stably attached to the outer wall of the dam slope body 1. It also acts as a barrier on the side when laying the concrete surface layer 6, ensuring that the concrete will not fall to one side of the ground.

[0031] See Figure 1 and Figure 2 The bottom of the extension layer 10 is provided with a drainage ditch 20, and the baffle 12 is set above the middle of the drainage ditch 20, so that the water flowing down through the concrete surface layer 6 can be directly discharged into the interior of the drainage ditch 20 and enter the drainage system. When the baffle 12 is set vertically, it can intercept impurities and stones sliding down through the concrete surface layer 6 in extreme weather, ensuring that they do not fall directly into the interior of the drainage ditch 20, and at the same time prevent the water from flowing too fast and being discharged directly to the opposite bank of the drainage ditch 20, causing rainwater to spread.

[0032] Working principle:

[0033] First, the reinforcing bar 2 can be inserted into the interior of the dam slope body 1. Then, the reinforcing plate 4 can be taken and inserted into the interior of the square trench 3. At the same time, mortar can be poured into the interior of the square trench 3 through the pouring hole 5. The mortar can then be used to position the reinforcing plate 4, ensuring that the reinforcing plate 4 can be stably set inside the square trench 3. Meanwhile, the concrete surface layer 6 can be laid in layers to the outer wall of the dam slope body 1 using the reinforcing plate 4. Furthermore, the concrete surface layer 6 can be used to cover the reinforcing bar 2 and the reinforcing plate 4.

[0034] Meanwhile, water flowing down through the concrete surface 6 can be directly discharged into the drainage ditch 20 and enter the drainage system. When the baffle 12 is set vertically, it can intercept impurities and stones sliding down through the concrete surface 6 in extreme weather, ensuring that they do not fall directly into the drainage ditch 20. At the same time, it prevents water from flowing too fast and being discharged directly to the other side of the drainage ditch 20, causing rainwater to spread.

[0035] Grass seeds can be sown inside the planting hole 8. After the grass seeds germinate, the roots of the plants can grow into the interior of the dam slope body 1 and then penetrate the covering layer 9 to form a vegetation layer, which increases the aesthetics of the top of the dam slope body 1 and will not easily cause landslides, thus increasing the overall coherence of the soil.
