Description

Technical Field

[0001] The invention relates to the technical field of bank protection, in particular to an automatic floating energy dissipation bank protection device and method for a sand-mudstone interlayer bank slope. Background Art

[0002] According to the dispatching plan, the water level in the reservoir area often rises and falls periodically between the normal water storage level and the flood control limit water level, forming a certain elevation drawdown zone. This periodic rise and fall of the water level causes the rock and soil in the drawdown zone to undergo repeated soaking and air drying processes, resulting in gradual damage and deterioration of the rock mass. This deterioration is particularly significant under factors such as water scouring, wave impact caused by the passage of ships, and ship impact at the shore, manifesting as dissolution, erosion, loosening (stripping), scouring, block cracking and disintegration, which is a major threat to the bank protection safety and ecological stability of the dock slope. In addition, when the water level drops, the drawdown zone will expose large areas of exposed rock and soil, which is in sharp contrast to the surrounding green plants and greatly affects the overall landscape effect.

[0003] Traditional energy dissipation revetment devices include: 1) solid box-type revetment, which can better protect the bank slope from scouring and deterioration, but it does not have the energy dissipation effect. The box surface is severely impacted by waves and has poor long-term stability. The reinforced concrete also pollutes the environment and is extremely unsightly; 2) flexible component type energy dissipation device, which can eliminate water energy, but in reservoirs with large water level fluctuations, it needs to be used on a large scale and is therefore expensive. The frame is easily damaged by long-term scouring and erosion by water flow; 3) ecological vegetation type revetment stabilizes the bank slope and improves water quality by planting vegetation on the revetment slope, but in the drawdown zone area, the long-term water rise and fall environment is harsh and vegetation is difficult to grow. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide an automatic floating energy dissipation bank protection device and method for sand-mudstone interlayer slope, which can combine the characteristics of water level drawdown in the reservoir area and have a good landscape effect while dissipating energy and protecting the bank.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: An automatic floating energy dissipation bank protection device for a sand-mudstone interlayer slope comprises a slideway anchored on the dock slope, a float movably arranged in the slideway, and a first connecting rod, a damping connector, a vegetation plate, a damping connector and an energy dissipation plate are sequentially connected to one side of the float.

[0006] The slideway is anchored on the dock slope through an upper supporting structure and a lower supporting structure.

[0007] The slideway, the upper supporting structure and the lower supporting structure are made of corrosion-resistant materials.

[0008] The damping connection member is a rubber damper, a hydraulic damper or a spring damper.

[0009] The vegetation plate is made of porous concrete, lightweight ceramsite concrete or high polymer composite material.

[0010] Multiple sets of automatic floating energy dissipation bank protection devices suitable for the bank slope of sand-mudstone interlayers are used in combination.

[0011] When multiple sets are used in combination, multiple groups of slides are arranged side by side and spaced apart along the dock slope; corresponding adjacent energy dissipation plates are connected by a first snap connector, adjacent floating plates are connected by a second snap connector; adjacent buoys are connected by a second connecting rod.

[0012] An automatic floating energy dissipation bank protection method for a dock suitable for a sand-mudstone interlayer reservoir bank slope comprises the following steps: Step 1: Arrange the size and quantity of the device according to the slope, width and splash area of ​​the dock bank; Step 2: Determine the installation location of the device according to the water level drop of the dock slope, prepare the required components and materials, and ensure that these components and materials meet the design requirements and have the corresponding quality standards; Step 3: Anchor the upper support structure and the lower support structure in the slope of the dock, with the upper support structure located at the water storage level and the lower support structure located at the flood control level; then install the slideway; Step 4: Assemble the device. Each set of devices is assembled in sequence, including the floating ball, the first connecting rod, the damping connector, the vegetation plate, the floating plate, and the energy dissipation plate; Step 5: Install the assembled device on the dock slope, and install the float in the slideway; multiple dock automatic floating energy dissipation revetment devices are assembled and connected through the second connecting rod 15, the first snap connector 16, and the second snap connector 17; Step 6: After the device is installed, it will automatically float on the water surface and rise and fall with the water level between the water storage level and the flood control level.

[0013] The present invention provides an automatic floating energy dissipation bank protection device and method for sand-mudstone interlayer slope, which has the following technical effects: 1) The present invention has strong environmental adaptability. The lifting structure is set in combination with the characteristics of water rise and fall in the reservoir area. Through the design of the float and the slide, the energy dissipation bank protection device can automatically float and change with the rise and fall of the water level, so that it can work effectively under various water level conditions, greatly enhancing the environmental adaptability of the device.

[0014] 2) The present invention greatly saves engineering costs, and does not require large-scale laying of equipment when facing a reservoir wharf with large water level fluctuations.

[0015] 3) The present invention sets an automatic floating structure to allow the vegetation structure to float on the water surface, which can ensure the normal growth of plants and avoid being submerged during water storage. It can play a good role in purifying water quality and ecological restoration, and can form an automatic floating ebb and flow landscape belt at the reservoir dock.

[0016] 4) The device adopts modular design, and multiple sets of devices can be easily nested or disassembled, which is convenient for expanding the revetment length according to actual needs, and also convenient for the maintenance and replacement of plants in each device including the vegetation board. The whole device realizes multiple functions of automatic floating, energy dissipation and revetment, and ecological restoration through reasonable connection structure and design.

DETAILED DESCRIPTION

[0021] like Figure 1 As shown, an automatic floating energy dissipation bank protection device for sand-mudstone interlayer slope includes a slide 7, which is anchored on the dock slope 1 through an upper support structure 5 and a lower support structure 6 to ensure that the slide 7 is stable and does not shake. A floating ball 8 is slidably arranged in the slide 7, and a limit plate is fixed on the outer end of the slide 7 away from the dock slope 1. A slide groove is provided on the limit plate, and the slide groove is located in the middle of the limit plate and arranged along the length direction. A first connecting rod 9 is connected to the outer end of the floating ball 8, and the first connecting rod 9 passes through the slide groove on the limit plate and is connected to the damping connector 10. One side of the vegetation plate 11 is connected to the damping connector 10, and the other side of the vegetation plate 11 is connected to another group of damping connectors 10, and the other group of damping connectors 10 fixes the energy dissipation plate 14 to the outermost side. The lower end of the vegetation plate 11 is fixed to the floating plate 12 by a buckle or bolt.

[0022] like Figure 2-3As shown, preferably, the device can be set up in multiple sets for combined use according to actual needs to ensure that the device can work effectively in different environments and conditions, help to achieve a more uniform energy dissipation and bank protection effect in a larger range, ensure the balance and comprehensiveness of the bank protection effect, and better share the load of the slope and the impact of the water flow.

[0023] When multiple sets of automatic floating energy dissipation bank protection devices are used in a reservoir dock, multiple groups of slideways 7 are arranged side by side and spaced apart along the dock slope 1. The number of buoys 8 corresponds to the number of slideways 7 and is arranged one by one. Corresponding damping connectors 10, vegetation plates 11, floating plates 12, energy dissipation plates 14, etc. are arranged in multiple groups according to actual needs. Adjacent energy dissipation plates 14 are connected by a first snap connector 16, and adjacent floating plates 12 are connected by a second snap connector 17. The first snap connector 16 and the second snap connector 17 have the characteristics of quick installation and disassembly, which ensures the tight connection between the components of the device and improves the stability and reliability of the overall structure.

[0024] like Figure 2-3 As shown, preferably, the side plates of the slideway 7 are provided with guide grooves along the length direction, and the two ends of the second connecting rod 15 pass through the corresponding guide grooves of the slideway 7 and are connected to the adjacent floating balls 8. The floating balls 8 are connected by the second connecting rod 15 so that the floating balls can be kept rising and falling synchronously when the water level changes, thereby improving the balance and stability of the device.

[0025] Preferably, the slide 7, the upper support structure 5 and the lower support structure 6 can be made of corrosion-resistant materials such as stainless steel, reinforced concrete or polymer material HDPE (high-density polyethylene). The material is light and easy to transport and install, has good corrosion resistance and wear resistance, and can greatly extend the service life of the device.

[0026] The upper support structure 5 and the lower support structure 6 are responsible for supporting the stability of the slide and need to be anchored on the bank slope. Therefore, they need to have strong structural strength and use anti-corrosion reinforced concrete as the structural material.

[0027] Preferably, the float 8 is made of a light and high-strength buoyancy material, preferably polyurethane foam, so as to ensure the stability and durability of the float 8 in the water, and at the same time, it can slide freely in the slide 7 to adapt to the change of water level.

[0028] Preferably, the first connecting rod 9 is made of a high-strength, corrosion-resistant alloy material, such as aluminum alloy or stainless steel. Both ends of the first connecting rod 9 are provided with threads or buckle structures, and are tightly connected to the float 8.

[0029] Preferably, the damping connector 10 is used to absorb the energy generated by wave impact and reduce the vibration and displacement of the entire structure of the energy dissipation and revetment device. The damping connector 10 can be a rubber damper, a hydraulic damper or a spring damper, etc. Preferably, a VFD-255-53 spring damper can be used.

[0030] Preferably, if Figure 2 As shown, each side of each vegetation plate 11 corresponds to two damping connectors 10 or multiple damping connectors 10 for connection to ensure stability.

[0031] Preferably, the vegetation board 11 is made of a lightweight porous material, such as porous concrete, lightweight expanded clay concrete or a polymer composite material, etc., which has good air permeability and water permeability, can provide the necessary support and nutrients for the plants, and effectively prevent the damage of the plant roots caused by stagnant water. The holes are hexagonal in design, and the side length is controlled between 0.4mm-5cm. The specific size needs to be determined according to the plant species, root development requirements and structural stability.

[0032] Preferably, the plants 13 planted in the vegetation board 11 are mainly required to grow rapidly and have underdeveloped root systems, and ground cover plants (such as ground cover dianthus, iris, daylily, etc.), herbaceous flowers (such as cosmos, cornflower, snake eye daisy, etc.), low shrubs (such as Ligustrum lucidum, boxwood, etc.) can be selected. The selected plant seedlings or seeds are placed in the holes of the vegetation board according to the designed layout, and the soil is gently compacted to ensure the stability of the plants. For larger seedlings, a small amount of plant fixers can be used for reinforcement.

[0033] Preferably, the floating plate 12 is made of lightweight and high-strength plastic or composite material, such as FRP (fiber reinforced plastic).

[0034] Preferably, the energy dissipation plate 14 is mainly used to further consume wave energy. The specific structural type of the energy dissipation plate 14 can be determined according to the actual situation of wave splashing at the dock, and can adopt inclined, trapezoidal, arc-shaped, porous and other structural shapes.

[0035] The design of the energy dissipation plate 14 needs to consider the incident angle and energy distribution of the wave to maximize the energy dissipation effect. The inclined shape is suitable for the situation where the wave mainly comes from a single direction, and the wave is guided and its energy is consumed by the inclined angle. The trapezoidal structure can provide a larger surface area, thereby more effectively dispersing and consuming the impact of the wave. The arc design can better adapt to waves from multiple directions and disperse the power of the wave through the arc surface. The porous design can disperse and weaken the energy of the wave through holes, and the design is carried out according to the situation.

[0036] The first snap connector 16 and the second snap connector 17 can be made of high-strength, corrosion-resistant plastic or polymer material, and can be connected in a spring snap, slot snap, slide snap, threaded snap, or other connection manner.

[0037] Preferably, a spring buckle structure can be used to maintain flexibility and facilitate installation and disassembly. The material used is high-strength polypropylene, which is low in cost and has certain strength and corrosion resistance.

[0038] Working principle and process: 1) Arrange the size and quantity of the device according to the actual conditions such as the slope, width, and splash area of ​​the dock slope; 2) Determine the installation location of the device according to the water level drop of the wharf slope, prepare the required components and materials, and ensure that these components and materials meet the design requirements and have the corresponding quality standards; 3) If Figure 3 As shown, an upper support structure 5 (located at the water storage level 3) and a lower support structure 6 (located at the flood control level 4) are installed, anchored in the slope of the wharf bank 1, and a slideway 7 is installed; 4) Figure 2 As shown, the device is assembled, and each set of the device is assembled in sequence, including the floating ball 8, the first connecting rod 9, the damping connecting piece 10, the vegetation plate 11, the floating plate 12, the energy dissipation plate 14 and other components; 5) If Figure 2 As shown, the assembled automatic floating energy dissipation bank protection device is installed on the dock slope, and the float 8 needs to be installed in the slide 7. The energy dissipation bank protection device can float automatically and rise and fall with the water level between the water storage level 5 and the flood control level 6. Multiple automatic floating energy dissipation bank protection devices are assembled and connected in pairs through components such as the second connecting rod 15, the first snap connector 16, and the second snap connector 17.
