Description

Technical Field

[0001] This utility model relates to the technical field of hydraulic slope protection equipment, and in particular to a hydraulic slope protection structure. Background Technology

[0002] Hydraulic slope protection is an important component of water conservancy projects, widely used for the protection of banks of various water bodies such as rivers, lakes, and reservoirs. It plays a crucial role in maintaining the stability of water conservancy facilities, protecting the surrounding ecological environment, and ensuring the safety of people's lives and property. From the perspective of engineering stability, hydraulic slope protection can resist the scouring and erosion of water flow, prevent the collapse of the embankment soil, ensure the integrity and strength of the embankment, and thus ensure the normal operation of water conservancy projects. For example, during flood season, the rapid water flow exerts a strong impact on the embankment. The slope protection structure can effectively disperse and buffer this force, avoiding dangerous situations such as breaches caused by excessive scouring. In terms of ecological environmental protection, a well-designed hydraulic slope protection can provide habitats and breeding grounds for aquatic organisms and surrounding flora and fauna, promoting the balance and stability of the ecosystem. At the same time, it helps reduce soil erosion, prevents nutrients and pollutants in the soil from entering the water body with the water flow, and protects water quality.

[0003] Traditional hydraulic slope protection structures, such as masonry and concrete slope protection, can resist water erosion to a certain extent. However, under long-term hydraulic action such as high-speed water flow and strong waves, the slope surface is prone to problems such as loosening of stones and peeling of concrete. This is especially true in some mountain rivers where the water flow is fast and carries a large amount of silt, which makes the wear and erosion of the slope more severe. As a result, the protective effect of the slope protection structure gradually decreases, increasing the risk of embankment collapse. Therefore, it is necessary to address this problem. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a hydraulic slope protection structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a hydraulic slope protection structure, including a dam, wherein a drainage channel is provided inside the dam, a filter plate is installed at the top of the drainage channel, a steel cage is installed on the top surface of the lower end of the dam, and an ecological layer is provided on the upper part of the dam and a buffer layer is provided on the lower part of the dam.

[0006] Preferably, the dam includes a foundation layer at the bottom, a crushed stone layer at the top of the foundation layer, and a layered gravel layer at the top of the crushed stone layer.

[0007] Preferably, the drainage ditch is located between the crushed stone layer and the graded gravel layer, the reinforcing cage is installed on the graded gravel layer, and crushed stone blocks are placed inside the reinforcing cage.

[0008] Preferably, the ecological layer is composed of several ecological bricks, the ecological bricks are hexagonal in shape, and green plants are planted inside the ecological bricks.

[0009] Preferably, the buffer layer includes cement cotton laid at the bottom of the embankment and two inclined buffer plates. Two fixed columns are hinged to one side of the buffer plate and fixed to the embankment. Two buffer rods are fixed to the other side of the buffer plate. The buffer rods are inserted into the bottom of the embankment and springs are installed at the bottom of the buffer rods.

[0010] Preferably, multiple water guide channels are provided at the lower end of the dam, and the other end of the water guide channels is connected to the inside of the steel cage.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: By placing crushed stones inside the steel cage, this utility model can alleviate the impact and wear of water flow on the bottom of the dam, thereby ensuring the protective effect of the slope protection structure and extending the service life of the device; furthermore, the inclined buffer plate and spring work together to increase the tilt angle of the buffer plate when subjected to water pressure, thereby absorbing the impact of water flow on the dam, and the spring can dissipate the impact through rebound; and the reinforcement with cement cotton can effectively prevent the stones on the slope surface from loosening and the concrete from peeling off; finally, it solves the problem that the slope surface is prone to loosening of stones and peeling off of concrete when subjected to high-speed water flow and strong waves for a long time, which reduces the protective effect of the slope protection structure.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example: See Figure 1-4 This utility model discloses a hydraulic slope protection structure, including a dam 1 for protecting riverbanks; a drainage channel is provided inside the dam 1 to facilitate the drainage of rainwater from the dam 1 into the river; a filter plate 2 is installed at the top of the drainage channel to prevent garbage from entering and clogging the channel; a steel cage 3 is installed on the top surface of the lower end of the dam 1 to facilitate the placement of gravel to reinforce the bottom of the dam 1; an ecological layer is provided on the upper part of the dam 1, and a buffer layer is provided at the lower part of the dam 1. The dam 1 includes a bottom layer... The foundation layer 6 facilitates the construction of the dam 1. A gravel layer 7 is provided on top of the foundation layer 6 to support the stability of the dam 1. A tiered gravel layer 8 is provided on top of the gravel layer 7 to facilitate water intake for the ecological layer and drainage of excess water into the river. A drainage channel is located between the gravel layer 7 and the tiered gravel layer 8. A steel cage 3 is installed on the tiered gravel layer 8, and gravel blocks are placed inside the steel cage 3. The ecological layer is composed of several ecological bricks 4, which facilitate the planting of greenery.

[0020] In this utility model, the ecological brick 4 is hexagonal in shape and planted with greenery. The buffer layer includes cement cotton 9 laid at the bottom of the embankment 1 and two inclined buffer plates 5. The buffer plates 5 help to mitigate the impact of water flow on the bottom of the embankment 1. Two fixed columns 10 are hinged to one side of the buffer plate 5 to facilitate the installation of the buffer plate 5. The fixed columns 10 are fixed to the embankment 1, and two buffer rods 11 are fixed to the other side of the buffer plate 5. The buffer rods 11 help to work with the springs 12 to mitigate the impact of water flow on the buffer plate 5. The buffer rods 11 are inserted into the lower part of the embankment 1, and springs 12 are installed at the bottom of the buffer rods 11 to help the buffer plate 5 return to its original position. Multiple water guide channels 13 are opened at the lower end of the embankment 1 to facilitate the diversion of rainwater into the river. The other end of the water guide channel 13 is connected to the inside of the steel cage 3.

[0021] Working principle: When this utility model is used, rainwater at the top of the dam 1 flows into the drainage ditch during rainy weather. The filter plate 2 filters out the garbage, and the drainage ditch discharges the rainwater into the river. The ecological layer absorbs the rainwater to provide the water source needed for the plants to grow. Excess water seeps into the ground after passing through the layered stone layer 8 and the crushed stone layer 7. The surface of the dam 1 at the bottom of the cement cotton 9 is provided with a water guide channel 13 to guide the rainwater into the river. When strong waves rush towards the bottom of the dam 1, the water waves will be buffered by the layers of crushed stones to reduce the impact force, which can ultimately prevent the bottom of the dam 1 from being damaged by the impact of the water waves. When the water level rises, the water waves hit, and the inclined buffer plate 5 is hit by the water waves and breaks the spring 12, causing it to tilt and absorb the impact. Then the spring 12 drives the buffer plate 5 to return to its original position, dissipating the impact and ultimately extending the service life of the device.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
