Description

Technical Field

[0001] This invention relates to the field of riverbank protection technology, and more specifically, to a riverbank protection device and method. Background Technology

[0002] Riverbank protection is a core structure in river regulation projects. Its core function is to stabilize riverbanks, restrain water flow, and prevent erosion and collapse of the banks under the shear force of flowing water. Traditional riverbank protection mainly uses rigid structures, such as cast-in-place concrete panels and masonry revetments. These structures resist the shear force of water flow through the inherent strength and integrity of the materials themselves.

[0003] However, rigid slope protection materials such as cast-in-place concrete panels and masonry slope protection rely on the strength and integrity of the materials themselves to form a continuous, impermeable slope cover layer, completely isolating the water flow from the slope soil to achieve erosion resistance. However, this impermeable structure severs the hydraulic connection between the river water and the groundwater on the slope. During the flood season, the water inside the slope accumulates for a long time and cannot be discharged in time. The slope protection is easily damaged by the long-term pressure of the river water and the slope. On the other hand, slope protection that uses geosynthetic materials to construct planting pits or planting layers on the slope and relies on the reinforcement and anchoring effect of plant roots to stabilize the slope, such as geocell grass slope protection and three-dimensional vegetation net slope protection, has the problem that the slope soil is in a long-term dry state during the non-flood season when the water level is low, and the plants cannot establish and grow. During the flood season, the water level rises, and the surface soil is easily submerged and eroded by high-speed water flow, causing large-scale erosion gullies. Over time, this leads to the problem of slope protection structure damage. Therefore, this invention proposes a river slope protection device and slope protection method to solve the above problems. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, embodiments of the present invention provide a riverbank protection device and a riverbank protection method to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a riverbank protection device and method, comprising: a riverbank protection body, a planting area, and an ecological flow guiding component. The ecological flow guiding component includes multiple alternately arranged flow guiding elements and ecological frames. A water storage tank is provided inside the flow guiding element, which can provide water to the soil inside the ecological frames and the planting area on both sides of the flow guiding element. The flow guiding element also includes a flow guiding channel set at the upper end of the water storage tank. The flow guiding element can guide the water flowing into the flow guiding element according to the water volume inside the water storage tank. When river water enters the flow guiding channel, the flow guiding channel can dissipate energy. The ecological flow guiding components are multiple and arranged in a stepped manner on the riverbank protection body.

[0006] Preferably, a gravel layer is provided at the lower end of the plant planting area, a first drainage pipe is provided inside the gravel layer, a second drainage pipe is provided inside the slope protection body, one end of the second drainage pipe is located inside the gravel layer, and multiple through holes are provided on the side wall of the first drainage pipe.

[0007] Preferably, a float is provided inside the water storage tank, and a connecting rod is fixedly connected to the float. One end of the connecting rod extends into the guide channel, and a limiting plate is fixedly connected to the side wall of the connecting rod. The limiting plate is located inside the guide channel.

[0008] Preferably, the top of the guide channel has a first slot, the side wall of the guide channel has a second slot, and the inside of the guide channel is rotatably connected to an isolation plate, which can guide the water entering the guide channel.

[0009] Preferably, the end of the connecting rod away from the limiting plate is in contact with one side of the isolation plate, a load-bearing block is fixedly connected to the end of the isolation plate near the connecting rod, a baffle is fixedly connected to the second slot inside the guide channel, and there are multiple first slots arranged in an array at the upper end of the guide channel.

[0010] Preferably, the upper end of the water storage tank is provided with multiple water inlets, the bottom of the water storage tank is provided with water outlets, and a third drainage pipe is provided inside the slope protection body. One end of the third drainage pipe is connected to the water outlet, and the other end of the third drainage pipe extends into the interior of the plant planting area.

[0011] Preferably, a support column is fixedly connected inside the ecological frame, and a connecting pipe is fixedly connected to one end of the support column. The two ends of the connecting pipe are respectively connected to the flow guides on both sides of the ecological frame, and multiple through holes are opened on the outer wall of the connecting pipe.

[0012] Preferably, a fixing plate is fixedly connected to the upper end of the ecological frame, and the fixing plate has multiple ventilation holes and ecological holes.

[0013] Preferably, the first drainage pipe is covered with a permeable cloth, the connecting pipe is covered with a permeable cloth, the third drainage pipe has multiple through holes at one end extending into the plant planting area, and the end of the third drainage pipe with through holes is covered with a permeable cloth, the second drainage pipe has multiple through holes at one end located inside the gravel layer, and the end with through holes is covered with a permeable cloth.

[0014] A slope protection method includes the following steps: S1. Multiple ecological flow guiding components are arranged in a stepped manner along the slope body. The ecological flow guiding components include multiple alternating flow guiding parts and ecological frames, and slope protection plants are planted in the ecological frames and plant planting areas. S2. Rainfall runoff is collected using a diversion channel, allowing the water to flow into a storage tank. At this time, the float is in a low position. After the water enters the diversion channel, it is guided by the isolation plate and flows directly into the storage tank. The accumulated water slowly seeps into the soil in the plant planting area and the ecological frame, providing continuous water for the plants. S3. The river water carries waves into the diversion channel to dissipate energy. When the water level in the storage tank is low, the water collection process in step S2 is repeated. As the water level in the storage tank rises, the isolation plate rotates, and the excess water enters the diversion channel and is directly diverted to the next diversion component or river channel through the second channel opening to prevent the storage tank from over-storing. S4. The water stored in the water storage tank is continuously released and supplied to the plant planting area and ecological frame through the water outlet, the third drainage pipe and the connecting pipe. Excess water in the plant planting area is discharged through the gravel layer, thus controlling the soil moisture content while supplying the plant growth.

[0015] The technical effects and advantages of this invention are as follows: This invention utilizes a stepped arrangement of ecological flow guiding components on the slope protection structure. This allows river water to cascade down the slope in stages, creating a hydraulic jump that dissipates energy and effectively reduces the scouring force of waves. It also slows down the rate of damage caused by water flow. Furthermore, by incorporating water storage tanks and diversion channels within the guiding components, it collects and stores rainfall runoff during non-flood seasons. During flood seasons, when water levels are too high, it automatically diverts excess water to lower levels or the river channel, preventing overflow from the storage tanks into the planting area and avoiding flooding. Simultaneously, it prevents disorderly overflow from scouring the slope. The water stored in the storage tanks provides a continuous water supply to the slope plants during drought periods, promoting plant growth and enhancing root system soil-fixing capabilities. This solves the problem of drought on the slope during non-flood seasons, which prevents plants from establishing and growing. Attached Figure Description

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0025] In actual production, during the flood season, water accumulates inside the bank slope for a long time and cannot be discharged in time. The slope is easily damaged by the long-term pressure of river water and the bank slope. This embodiment is invented to solve the above problems.

[0026] Please see Figures 1 to 7 As shown, an embodiment of the present invention provides a riverbank protection device and method, comprising a slope protection body 1, a planting area 2, and an ecological flow guiding component 3. The ecological flow guiding component 3 includes multiple alternately arranged flow guiding elements 31 and ecological frames 32. A water storage tank 311 is provided inside each flow guiding element 31, which can provide water to the soil inside the ecological frames 32 and the planting area 2 on both sides of the flow guiding element 31. The flow guiding element 31 also includes a flow guiding channel 312 disposed at the upper end of the water storage tank 311, which can... The water flowing into the guide component 31 is guided according to the water volume inside the water storage tank 311. When the river water enters the guide channel 312, if the water level in the water storage tank 311 is low, the river water enters the guide channel 312 and falls to the bottom of the guide channel 312 to dissipate energy, and then enters the water storage tank 311. If the water level in the water storage tank 311 is high, the river water enters the guide channel 312 and flows along the isolation plate 318 to the top of the guide channel 312 to dissipate energy. There are multiple ecological guide components 3 arranged in a stepped manner on the slope protection body 1.

[0027] Please see Figure 1 and Figure 2As shown, a gravel layer 21 is provided at the lower end of the plant planting area 2. A first drainage pipe 22 is provided inside the gravel layer 21. A second drainage pipe 11 is provided inside the slope protection body 1. One end of the second drainage pipe 11 is located inside the gravel layer 21. Multiple through holes are opened on the side wall of the first drainage pipe 22. The side wall of the first drainage pipe 22 is connected to the second drainage pipe 11 to quickly drain the water inside the first drainage pipe 22 into the river. Both ends of the first drainage pipe 22 are connected to external pipes to prevent the water inside the first drainage pipe 22 from being unable to drain when the river water level is too high.

[0028] Please see Figure 4 and Figure 6 As shown, a float ball 313 is installed inside the water storage tank 311, and a connecting rod 314 is fixedly connected to the float ball 313. One end of the connecting rod 314 extends into the guide channel 312. A limiting plate 315 is fixedly connected to the side wall of the connecting rod 314, and the limiting plate 315 is installed inside the guide channel 312.

[0029] Please see Figure 3 and Figure 4 As shown, the top of the guide channel 312 is provided with a first slot 316, and the side wall of the guide channel 312 is provided with a second slot 317. An isolation plate 318 is rotatably connected inside the guide channel 312. A rotating shaft is fixedly connected inside the isolation plate 318. The two ends of the rotating shaft are rotatably connected to the inner wall of the guide channel 312. The isolation plate 318 can guide the water entering the guide channel 312.

[0030] Please see Figure 4 and Figure 6 As shown, the end of the connecting rod 314 away from the limiting plate 315 is in contact with one side of the isolation plate 318. A load-bearing block is fixedly connected to the end of the isolation plate 318 near the connecting rod 314. A baffle is fixedly connected to the second slot 317 inside the guide channel 312. There are multiple first slots 316 arranged in an array at the upper end of the guide channel 312. When the water level in the storage tank 311 is low, the float 313 is in a low position. At this time, the water entering the guide channel 312 through the first slot 316 is guided by the isolation plate 318 and falls to the bottom of the guide channel 312 and enters the storage tank 311. When the water level in the storage tank 311 is high... When the float 313 rises, it drives the connecting rod 314 to push the isolation plate 318 to rotate. At this time, the water that enters the guide channel 312 through the first slot 316 is guided by the isolation plate 318 and then discharged from the guide channel 312 through the second slot 317. In order to prevent the connecting rod 314 inside the water storage tank 311 or the isolation plate 318 inside the guide channel 312 from getting stuck due to siltation, the staff can set up filter screens at the first slot 316 and the second slot 317 of the guide channel 312 as needed, so as to prevent silt from entering the guide channel 312 and the water storage tank 311 with the river water or runoff.

[0031] Please see Figure 2 and Figure 4 As shown, the upper end of the water storage tank 311 is provided with multiple water inlets, and the bottom of the water storage tank 311 is provided with water outlets. The slope protection body 1 is provided with a third drainage pipe 12. One end of the third drainage pipe 12 is connected to the water outlet, and the other end of the third drainage pipe 12 extends into the interior of the plant planting area 2.

[0032] Please see Figure 5 and Figure 6 As shown, a support column 321 is fixedly connected inside the ecological frame 32. One end of the support column 321 is fixedly connected to a connecting pipe 322. The two ends of the connecting pipe 322 are respectively connected to the guide members 31 on both sides of the ecological frame 32. The outer wall of the connecting pipe 322 has multiple through holes, such as... Figure 6 As shown, the guide members 31 on both sides of the ecological frame 32 are connected by a connecting pipe 322. At this time, multiple water storage tanks 311 form a communicating vessel, so that the water inside the multiple water storage tanks 311 can evenly seep into the adjacent ecological frames 32, thereby ensuring that the water is evenly distributed among the ecological frames 32. Figure 7 As shown, a sealing plate can be installed in the middle of the connecting pipe 322, so that the guide components 31 on both sides of the ecological frame 32 are connected to the ecological frame 32. However, due to the sealing plate, the guide components 31 on both sides of the ecological frame 32 are not interconnected online, so that after the water is drawn out from the water storage tank 311, a pipe network is formed only inside the adjacent ecological frame 32, thus ensuring that each has the function of independent control according to the water level of the guide component 31. The staff can change the connection method of the connecting pipe 322 according to the actual work needs, which is not limited here.

[0033] Please see Figure 5 and Figure 6 As shown, a fixing plate is fixedly connected to the upper end of the ecological frame 32. The fixing plate has multiple ventilation holes to ensure soil permeability. The fixing plate has ecological holes 323 for the roots of plants inside the ecological frame 32 to pass through. By setting the fixing plate, it is prevented that too much soil will be carried away and cause soil erosion when water flows through the top of the ecological frame 32.

[0034] Please see Figure 1 As shown, the first drainage pipe 22 is covered with a water-permeable cloth, the connecting pipe 322 is covered with a water-permeable cloth, the third drainage pipe 12 extends into the plant planting area 2 and has multiple through holes at one end, and the end of the third drainage pipe 12 with through holes is covered with a water-permeable cloth, the second drainage pipe 11 is located inside the gravel layer 21 and has multiple through holes at one end, and the end with through holes is covered with a water-permeable cloth.

[0035] During use, in the flood season, the river level rises and rainfall is abundant. The river water carries waves that impact the guide component 31. When the river water rushes towards the multiple sets of ecological guide components 3 arranged in a stepped manner, it forms a hydraulic jump energy dissipation. When the impact force of the river water is large, the river water enters the guide channel 312 through the second slot 317 and falls to the bottom of the guide channel 312. The falling water further dissipates the energy of the water that has entered the guide channel 312. The water storage tank 311 also dissipates the energy of the rainfall and the river water that has entered the guide channel 312. Water is collected to prevent the river level from rising too quickly and overflowing the revetment during heavy rainfall, which would cause a large number of ecological frames 32 to be submerged. When heavy rainfall falls into the plant planting area 2, the water inside the plant planting area 2 accumulates downward and eventually seeps out to the gravel layer 21, and is discharged through the first drainage pipe 22 and the second drainage pipe 11 inside the gravel layer 21. This prevents the problem of water accumulating inside the bank slope for a long time during the flood season and not being able to be discharged in time, which would make the revetment easily damaged by the long-term pressure of the river water and the bank slope. Example 2

[0036] In practical use, it was found that during the non-flood season when the water level is low, the slope soil is in a state of drought for a long time, and plants cannot be planted and grow. During the flood season, when the water level rises, the surface soil is easily submerged and eroded by the high-speed water flow, causing large-scale erosion gullies. Over time, this leads to the damage of the slope protection structure. Further improvements have been made based on the above-mentioned embodiments.

[0037] Based on the above embodiments, during use, when the river level is low and rainfall is small during the non-flood season, the rainwater runoff is collected through the diversion channel 312 and allowed to flow into the storage tank 311 for storage. When the water level inside the storage tank 311 is low, the float 313 is at a low position. At this time, the section of the isolation plate 318 near the load block is close to the bottom of the diversion channel 312. After the rainwater enters the diversion channel 312, it flows through the isolation plate 318 into the bottom of the diversion channel 312 and then into the storage tank 311 through the water inlet. Internally, the accumulated water slowly seeps into the soil within the plant planting area 2 and the ecological frame 32 through the third drainage pipe 12 and the connecting pipe 322, providing continuous water for the plants. During the flood season, when the river level rises and rainfall is abundant, the float 313 rises when the water level in the storage tank 311 is high, causing the connecting rod 314 to push the isolation plate 318 to rotate. At this time, the section of the isolation plate 318 near the load block is away from the bottom of the guide channel 312. After the rainwater enters the guide channel 312, it is guided by the isolation plate 318 and then flows through the second channel. The water flows out through outlet 317 and into the lower ecological diversion component 3 or the river channel. When the river level is high during the flood season, submerging the second outlet 317 and the water level in the storage tank 311 is high, the river water rushes in from the second outlet 317 and flows along the isolation plate 318 towards the first outlet 316. Since the first outlet 316 is at the top of the diversion component 31, when the water flows towards the first outlet 316, the water impacts the isolation plate 318 and the walls of the diversion channel 312. Through turbulent diffusion and impact energy dissipation, when the water is stored... When the water level in the trough 311 is low but the river water level is high and submerges the second trough opening 317, the river water flows into the diversion channel 312 through the second trough opening 317 and falls to the bottom of the diversion channel 312, and enters the water storage tank 311, causing the water level inside the water storage tank 311 to rise rapidly. This causes the float 313 to float up and drive the isolation plate 318 to rotate, thereby preventing excessive water storage inside the water storage tank 311 from overflowing into the plant planting area and causing flooding, or causing excessive water accumulation inside the plant planting area 2 and increasing the pressure on the slope protection body 1. Example 3

[0038] Based on the above embodiments, this embodiment also provides a slope protection method, which specifically includes the following steps: S1. Multiple ecological flow guiding components 3 are arranged in a stepped manner along the slope protection body 1. The ecological flow guiding components 3 include multiple alternating flow guiding parts 31 and ecological frames 32, and slope protection plants are planted in the ecological frames 32 and the plant planting area 2. S2. Rainfall runoff is collected using the diversion channel 312 and the water flows into the storage tank 311 for storage. At this time, the float 313 is in a low position. After the water flows into the diversion channel 312, it is diverted directly into the storage tank 311 through the isolation plate 318. The accumulated water slowly seeps into the soil in the plant planting area 2 and the ecological frame 32 to provide continuous water for the plants. S3. The river water carries waves into the diversion channel 312 to dissipate energy. When the water level in the storage tank 311 is low, the water collection process in step S2 is repeated. As the water level in the storage tank 311 rises, the isolation plate 318 rotates. Excess water enters the diversion channel 312 and is directly diverted through the second channel opening 317 to the lower diversion component 31 or the river channel to prevent the storage tank 311 from over-storing. S4. The water stored in the water storage tank 311 is continuously released and supplied to the plant planting area 2 and the ecological frame 32 through the water outlet, the third drainage pipe 12 and the connecting pipe 322. Excess water in the plant planting area 2 is discharged through the gravel layer 21, thus controlling the soil moisture content while supplying the plant growth.

[0039] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
