Description

Technical Field

[0001] This utility model relates to the field of dam protection technology, specifically a seepage prevention and ecological protection structure for water conservancy dams. Background Technology

[0002] Dams are hydraulic structures built for purposes such as flood control, tide blocking, and water storage. They play an important role in water conservancy projects. Common types of dams include earth dams, rock dams, and concrete dams. Different types of dams are suitable for different geographical environments and engineering needs. Dams are usually composed of dam body, slope protection, drainage system, etc. A reasonable structural design can ensure the stability and durability of dams.

[0003] Ecological seepage prevention in water conservancy projects integrates ecological concepts while ensuring the seepage prevention function of the dams, achieving harmonious coexistence between the project and nature, and improving the safety and stability of the dams. Ecological seepage prevention in water conservancy projects plays an important role in reducing soil erosion, purifying water quality, and regulating local climate, and helps to promote the sustainable use of water resources and the protection of the ecological environment.

[0004] Existing water conservancy projects and dams are susceptible to seepage problems when faced with severe weather, such as torrential rain. Prolonged water flow can cause seepage inside the dam, leading to localized disturbance of the dam soil and, in severe cases, collapse.

[0005] Therefore, an ecological protection structure for seepage prevention in water conservancy dams is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

After the protective plate fits the dam body, it can protect the dam body. At the same time, adding a geomembrane can reduce the direct contact between rainwater and the dam body during heavy rain, and the geomembrane can prevent rainwater from seeping into the interior of the dam body, further improving the seepage prevention work of the dam body.

[0008] Preferably, a support plate is fixedly connected to the top of the protective plate; both the support plate and the protective plate have grooves inside; a sliding plate is provided inside the groove; the sliding plate is slidably connected inside the groove; a screw rod is fixedly connected to the top of the sliding plate; by adding the sliding plate, the geomembrane can be fixed. In the event of heavy rain, if the geomembrane absorbs too much rainwater, it will shake. At this time, the sliding plate can fix it and reduce the occurrence of geomembrane shaking or displacement.

[0009] Preferably, each pair of steps has multiple drainage pipes fixedly connected inside; a flow-limiting plate is fixedly connected to the top of the steps; by adding drainage pipes, rainwater dripping onto the top of the flow-limiting plate can be discharged, reducing the accumulation of rainwater on the top of the steps for a long time, thus preventing water seepage.

[0010] Preferably, a planting area is fixed to the top of the protective plate; the planting area and the protective plate are correspondingly arranged; by adding the planting area, water flowing out of the step gaps and the inside of the guide pipe can be absorbed, and the water can also be slowed down and moisturized, effectively increasing the durability of the protective plate.

[0011] Preferably, a filter screen is provided on the outer wall of the guide pipe; the filter screen and the guide pipe are correspondingly arranged; by adding a filter screen, impurities such as leaves attached to the rainwater can be blocked, and they can be processed together later, reducing the situation where rainwater and leaves get stuck at the top of the steps and inside the guide pipe.

[0012] Preferably, the slide plate is damped; by making the slide plate damped, the slide plate can stop as soon as the hand is released when it slides in the groove, reducing the occurrence of the slide plate sliding inside.

[0013] The advantages of this utility model are:

[0014] 1. The seepage prevention and ecological protection structure for water conservancy dams described in this utility model can be made to fit the protective plate and the dam body by adding anchor bolts. After the protective plate fits the dam body, it can protect the dam body. At the same time, adding geomembrane can reduce the direct contact between rainwater and the dam body when facing heavy rain. In addition, geomembrane can prevent rainwater from seeping into the interior of the dam body, further improving the seepage prevention of the dam body.

[0015] 2. The seepage prevention and ecological protection structure for water conservancy dams described in this utility model can fix the geomembrane by adding a sliding plate. In the event of heavy rain, if the geomembrane absorbs too much rainwater, it will shake. At this time, the sliding plate can fix it and reduce the occurrence of geomembrane shaking or displacement.

[0023] 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 scope of protection of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 5As shown in the embodiment of this utility model, a seepage prevention and ecological protection structure for a water conservancy project dam includes a dam body 1, with a protective plate 11 installed on the top of the dam body 1; threaded holes 13 are formed inside the protective plate 11 and the dam body 1; anchor rods 12 are installed inside the threaded holes 13; the anchor rods 12 are slidably connected inside the threaded holes 13; a pair of steps 14 are fixedly connected to the top of the protective plate 11; a sandwich layer 15 is formed inside the protective plate 11; and a... Geomembrane 16; a baffle 17 is provided on the inner side of the interlayer 15; the interlayer 15 and the baffle 17 are correspondingly arranged; align the threaded hole 13 on the protective plate 11 with the threaded hole 13 on the embankment body 1, and then insert the anchor rod 12 into the threaded hole 13. After inserting the anchor rod 12 into the threaded hole 13, the anchor rod 12 can be rotated. The anchor rod 12 will then rotate inside the threaded hole 13, and at the same time, the anchor rod 12 will slide while rotating until it abuts against the embankment body 1. After the threaded hole 13 is reached, the protective plate 11 and the embankment body 1 will be properly attached and fixed. When the river surges, the step 14 will hold back and block the river water. Simultaneously, the geomembrane 16 installed inside the interlayer 15 of the protective plate 11 will absorb rainwater during heavy rain, preventing it from directly seeping into the embankment. When the geomembrane 16 needs to be replaced, the baffle 17 is removed from the protective plate 11. The geomembrane 16 can be replaced by removing it. By adding anchor bolts 12, the protective plate 11 and the dam body 1 can be attached together. After the protective plate 11 is attached to the dam body 1, it can protect the dam body 1. At the same time, adding geomembrane 16 can reduce the direct contact between rainwater and the dam body 1 when facing heavy rain. In addition, geomembrane 16 can prevent rainwater from seeping into the interior of the dam body 1, further improving the seepage prevention work of the dam body 1.

[0026] like Figures 1 to 3 As shown, a support plate 21 is fixedly connected to the top of the protective plate 11; both the support plate 21 and the protective plate 11 have grooves 22 inside; a sliding plate 2 is provided inside the groove 22; the sliding plate 2 is slidably connected inside the groove 22; a screw rod 23 is fixedly connected to the top of the sliding plate 2; in case of heavy rain, the screw rod 23 can be rotated, and then the screw rod 23 will rotate inside the sliding plate 2. When the screw rod 23 rotates, it will drive the sliding plate 2 to start moving downwards, pushing the sliding plate 2 downwards until it stops against the geomembrane 16; by adding the sliding plate 2, the geomembrane 16 can be fixed. In case of heavy rain, if the geomembrane 16 absorbs too much rainwater, it will shake. At this time, the sliding plate 2 can fix it, reducing the occurrence of shaking or displacement of the geomembrane 16.

[0027] like Figures 1 to 3 As shown, multiple guide pipes 3 are fixedly connected inside each pair of steps 14; a flow-limiting plate 31 is fixedly connected to the top of the steps 14; when rainwater drips onto the steps 14, the rainwater is blocked by the flow-limiting plate 31 and stays at the top of the steps 14. Then the rainwater flows down the steps 14 to the top of the guide pipes 3, and finally flows out through the bottom of the guide pipes 3 to the outside of the protective plate 11; by adding guide pipes 3, the rainwater dripping onto the top of the flow-limiting plate 31 can be discharged, reducing the long-term accumulation of rainwater on the top of the steps 14, thus preventing water seepage.

[0028] like Figure 5 As shown, a planting area 4 is fixedly attached to the top of the protective plate 11; the planting area 4 and the protective plate 11 are set accordingly; soil can be added into the planting area 4 and then greening can be carried out. When the greening grows, it can make the dam body 1 look more beautiful as a whole; by adding the planting area 4, the water flowing out of the gaps in the steps 14 and the inside of the diversion pipe 3 can be absorbed, and the water can also be slowed down and moisturized, which effectively increases the durability of the protective plate 11.

[0029] like Figures 1 to 3 As shown, a filter screen 5 is provided on the outer wall of the guide pipe 3; the filter screen 5 and the guide pipe 3 are arranged correspondingly; when rainwater or river water rises and falls onto the steps 14, the rainwater will flow out through the guide pipe 3. At this time, the filter screen 5 can be inserted into the guide pipe 3. Subsequently, when the rainwater comes out through the guide pipe 3, impurities and leaves in the rainwater will be blocked by the filter screen 5; by adding the filter screen 5, impurities and leaves attached to the rainwater can be blocked, and they can be processed together later, reducing the situation where rainwater and leaves get stuck at the top of the steps 14 and inside the guide pipe 3.

[0030] like Figures 1 to 2 As shown, the slide plate 2 is damped; by making the slide plate 2 damped, the slide plate 2 can stop when the hand is released when sliding in the slide groove 22, reducing the occurrence of the slide plate 2 sliding inside the slide groove 22.

[0031] Working principle: Align the threaded holes 13 on the protective plate 11 with the threaded holes 13 on the embankment body 1, then insert the anchor rod 12 into the threaded hole 13. After inserting the anchor rod 12, rotate it. The anchor rod 12 will rotate inside the threaded hole 13 and slide simultaneously until it stops against the threaded hole 13 on the embankment body 1. After stopping, the protective plate 11 and the embankment body 1 will be properly attached and fixed. When encountering river surge, the steps 14 will hold back and block the river water. At the same time, the geomembrane 16 installed in the interlayer 15 inside the protective plate 11 will absorb rainwater that falls onto the protective plate 11 during heavy rain, preventing rainwater from directly seeping into the embankment. When the geomembrane 16 needs to be replaced, simply remove the baffle 17 from the protective plate 11 to replace the geomembrane 16. In case of heavy rain, the screw 23 can be rotated, causing it to rotate inside the slide plate 2. This rotation drives the slide plate 2 downwards until it hits the geomembrane 16. When rainwater drips onto the steps 14, it is blocked by the flow-limiting plate 31 and remains at the top of the steps 14. The rainwater then flows down the steps 14 to the top of the guide pipe 3 and finally out through the bottom of the guide pipe 3 to the outside of the protective plate 11. When rainwater or river water rises and falls onto the steps 14, it flows out through the guide pipe 3. At this time, a filter screen 5 can be inserted into the guide pipe 3. As the rainwater exits through the guide pipe 3, impurities and leaves in the rainwater are blocked by the filter screen 5. Soil can then be added to the planting area 4 for planting. Once the greenery grows, the dam body 1 will look more aesthetically pleasing.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
