Description

Technical Field

[0001] This utility model relates to the field of bank protection engineering technology, and in particular to a rigid bank protection structure based on porous media modification. Background Technology

[0002] In water conservancy and municipal landscape engineering, revetment structures are key facilities for ensuring bank slope stability and preventing soil erosion. Rigid revetments (such as concrete revetments and masonry revetments) are widely used due to their high strength and strong erosion resistance. However, existing rigid revetment structures, being dense, cannot allow rainwater to infiltrate and be stored. During rainfall, surface runoff on the upper part of the bank slope tends to accumulate, increasing the risk of bank erosion. In dry periods, they cannot provide continuous water supply to the slope vegetation. Furthermore, they can only intercept pollutants in water bodies or surface runoff, but cannot effectively adsorb and degrade them, which can easily lead to the deterioration of the aquatic environment.

[0003] Therefore, a rigid revetment structure based on porous media has been developed that has high erosion resistance and hydrological regulation capabilities, and can purify pollutants. Utility Model Content

[0004] To overcome the shortcomings of existing rigid revetment structures, such as the tendency for surface runoff to accumulate on the upper part of the bank slope during rainfall, increasing the risk of bank erosion, and the inability to purify pollutants in the water, this utility model provides a rigid revetment structure based on porous media modification that has high erosion resistance and hydrological regulation capabilities, and can purify pollutants.

[0005] The technical solution is as follows: A rigid revetment structure based on porous media modification includes a slope, a rigid structure, a sand and gravel layer, a soil layer, a filter screen, a water storage component, and a purification component. The front side of the slope is connected to the rigid structure, the lower part of the rigid structure is connected to multiple sand and gravel layers, the upper part of the rigid structure is connected to multiple soil layers, and the upper side of each soil layer is connected to a filter screen. The revetment is equipped with a water storage component capable of storing water, and the revetment is also equipped with a purification component capable of purifying the water.

[0006] Optionally, the water storage assembly includes a water intake pipe, a pump body, a connecting frame, a spray pipe, and spray nozzles. The water intake pipe is connected inside the slope and passes through the rigid structure. The connecting frame is connected to the slope, and the pump body is connected to the connecting frame. The pump body is connected to the water intake pipe, and the spray pipe is connected to the upper side of the pump body. Spray nozzles are connected to the spray pipe.

[0007] Optionally, the water intake pipe may be made of PVC.

[0008] Optionally, the purification component includes inclined blocks and carbon boxes, with inclined blocks connected to the upper front side of the soil layer, and carbon boxes slidably connected inside each inclined block.

[0009] Optionally, it also includes columns, with multiple columns connected to the rigid structure.

[0010] Optionally, water-permeable holes are provided on the column.

[0011] This invention has the following advantages: It stores rainwater through a sand and gravel layer, and sprays it evenly onto the soil layer through atomization via a sprinkler pipe and nozzle during droughts to replenish vegetation. At the same time, it purifies the water through activated carbon in the carbon box, achieving high-strength erosion resistance and hydrological regulation capabilities, as well as the ability to purify pollutants.

[0017] 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.

[0018] A rigid revetment structure based on porous media modification, such as Figures 1-4 As shown, it includes a slope 1, a rigid structure 2, a sand and gravel layer 3, a soil layer 4, a filter screen 5, columns 13, a water storage component, and a purification component. The front of the slope 1 is connected to the rigid structure 2. Five sand and gravel layers 3 are connected to the lower part of the rigid structure 2. Twelve soil layers 4 are connected to the upper part of the rigid structure 2. Filter screens 5 are connected to the upper side of each soil layer 4. Multiple columns 13 are connected to the rigid structure 2. Water permeable holes are opened on each column 13. A water storage component and a purification component are also provided on the slope.

[0019] like Figure 2 As shown, the water storage assembly includes a water intake pipe 6, a pump body 7, a connecting frame 8, a spray pipe 9, and a spray nozzle 10. The water intake pipe 6 is connected inside the slope 1. The water intake pipe 6 is made of PVC material and passes through the rigid structure 2. The connecting frame 8 is connected to the slope 1. The pump body 7 is connected to the connecting frame 8. The pump body 7 is connected to the water intake pipe 6. The spray pipe 9 is connected to the upper side of the pump body 7. The spray nozzle 10 is connected to the spray pipe 9.

[0020] like Figure 3 and Figure 4 As shown, the purification component includes inclined blocks 11 and carbon boxes 12. Inclined blocks 11 are connected to the upper front side of the soil layer 4, and carbon boxes 12 are slidably connected inside each inclined block 11.

[0021] When using this invention, the slope 1 is first installed in the slope protection area of ​​the water body. During rainfall, surface runoff is first filtered through the filter screen 5 on the upper side of the soil layer 4. Some rainwater infiltrates into the soil layer 4 to provide water for the vegetation, while excess rainwater infiltrates into the sand and gravel layer 3 below the rigid structure 2 and is stored. At the same time, some water in the water body enters the sand and gravel layer 3 through the permeable holes of the rigid structure 2, realizing the exchange of materials between the bank slope and the water body. During drought, the pump 7 is started, and the water stored in the sand and gravel layer 3 is extracted through the water intake pipe 6. After being atomized by the spray pipe 9 and the spray nozzle 10, the water is evenly sprayed onto the soil layer 4 to replenish the vegetation. Pollutants in the surface runoff or spray water are initially treated by the vegetation and microorganisms when passing through the soil layer 4. Then, they flow through the carbon box 12 in the inclined block 11 and are adsorbed and purified by activated carbon. Finally, they enter the water body or infiltrate into the ground. The column 13 and the rigid structure 2 work together to resist the scouring of the water flow and ensure the stability of the bank slope. Thus, it plays a role in providing high-strength scouring resistance and hydrological regulation, as well as purifying pollutants.
