Description

Technical Field

[0001] The invention relates to the technical field of river bank slope protection, in particular to an anti-scouring ecological slope protection system for a sandy soil river bank. Background Art

[0002] Ecological slope protection is a slope protection that uses the interaction between plants, rocks and soil to protect and reinforce the surface of the slope. Riverbank ecological slope protection has the functions of preventing soil erosion, reducing water pressure on the slope, intercepting rainfall and improving the environment.

[0003] Domestic river ecological revetment construction has a long history. In ancient river management projects, willow branches, bamboos and other materials were used to weave gabions to stabilize the river bank. This ancient method is becoming more and more popular. Domestic technicians have proposed a variety of different revetment technologies on this basis. In general, one is the "all-natural" revetment, which is to use plant measures to stabilize the water bank; the other is the "semi-natural" revetment, which is to use a combination of engineering measures and plant measures. Specifically, there are the following technologies: grass slope protection technology, shelterbelt revetment technology, three-dimensional mesh mat slope protection technology, ecological bag slope protection technology, gabion stone cage slope protection technology, mortar stone slope protection technology, and dry stone slope protection technology.

[0004] Due to the soil characteristics of sandy riverbanks, most plants are difficult to survive and it is difficult to consolidate the riverbank soil through greening. The existing slope protection does not have any protective measures. Under the scouring of water flow, it is easy to damage the surface structure of the slope protection, which will cause the collapse of the slope protection in the long run. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] See also Figure 1-3 The present invention provides a sandy soil river bank anti-scour ecological slope protection system, comprising:

[0044] The slope protection 1 comprises a forest cultivation area 2, a block slope protection area 3 and an aquatic plant cultivation area 4 which are arranged in sequence from top to bottom along the river bank;

[0045] The block slope protection area 3, an upper fixing frame 5 is arranged above the block slope protection area 3, a lower fixing frame 6 is arranged below the block slope protection area 3, a stone 7 is arranged between the upper fixing frame 5 and the lower fixing frame 6, and a planting layer is arranged on the upper and lower sides of the stone 7, and a planting groove is opened on the stone 7;

[0046] The wave-breaking component 8 includes a plurality of resistance wells 81 arranged on both sides of the block slope protection area 3, wherein a damping medium is arranged in the resistance wells 81, a damping plate 82 is arranged in the resistance wells 81, a rotating shaft 83 is arranged on the damping plate 82, and both ends of the rotating shaft 83 are rotatably connected to the boss 9 on the block slope protection area 3, and a water blocking plate 84 is arranged on the rotating shaft 83, and the water blocking plate 84 is arranged along the axial direction of the rotating shaft 83.

[0047] A guide rod 10 is arranged in the resistance well 81, a through hole is arranged on the damping plate 82, the damping plate 82 is inserted into the through hole, a first spring 11 is arranged between the damping plate 82 and the resistance well 81, and the first spring 11 is sleeved on the guide rod 10. It is used to provide elastic restoring force to the damping plate, and the damping plate can be restored to its original position after the water flow impact ends.

[0048] The water blocking plate 84 includes a plurality of water blocking plate units 841, and the water blocking plate units 841 are connected to each other through elastic elements 842. Since the flow velocities in different areas of the water flow are different, when the water blocking plate is impacted by the water flow, the water blocking plate units are subjected to different impact forces. Under the action of the elastic elements, the water blocking plate units are misaligned, thereby dividing the water flow into several sections, reducing the impact effect of the water flow on the river bank. The elastic elements are specifically elastic rubber blocks.

[0049] A connecting rod assembly 12 is arranged above the resistance well 81, one end of the connecting rod assembly 12 is connected to the damping plate 82, and the other end of the connecting rod assembly 12 is connected to another adjacent damping plate 82. The connecting rod assembly 12 includes a connecting rod 121 and two second springs 122, and the two ends of the connecting rod 121 are respectively connected to a second spring 122, and the second spring 122 is connected to the corresponding damping plate 82. Through the connecting rod assembly, each wave-breaking assembly can be connected as a whole, thereby improving the impact resistance and wave-breaking ability of the wave-breaking assembly; when the impact force of the water flow is small, the damping plate is not enough to make the connecting rod drive the adjacent damping plate to rotate, and when the impact force of the water flow is large, the damping plate overcomes the elastic force of the second spring to drive the connecting rod to drive the upper damping plate to rotate, and so on, so that the wave-breaking assembly on the entire slope protection can be operated.

[0050] The aquatic plant cultivation area 4 is planted with first aquatic plants 13, and a pebble layer 14 is provided in the aquatic plant cultivation area 4. The pebble layer can reduce the scouring of river bank soil by water flow, and the first aquatic plants are emergent plants, such as reeds, water plantains and sedges.

[0051] The aquatic plant cultivation area 4 is provided with a wave-breaking buoy 15, and at least one fixing rod 16 is provided at the bottom of the wave-breaking buoy 15. An ecological floating bed 17 is provided on one side of the wave-breaking buoy 15, and a second aquatic plant 18 is provided on the ecological floating bed 17. A trapezoidal hollow box 19 is provided on the wave-breaking buoy 15, and a plurality of through holes 20 are provided on the box 19. A deflection plate 21 is provided on one side of the through holes 20, and the deflection plate 21 is fixedly connected to the box 19. The combination of the hollow trapezoidal wave-breaking buoy and the ecological floating bed ensures the anti-corrosion safety of the river bank slope protection, and can also provide a sustainable living space for animals and plants, thereby realizing the ecological, beautiful, efficient and multi-functional river bank slope protection. The deflection plate can partially deflect the water flow, such as Figure 6 As shown, the dotted arrow is the direction of the water flow, and the solid arrow is the direction of the turned water flow. The turned water flow collides with the next wave of water flow, which can offset the kinetic energy of the water flow, thereby reducing the scouring of the river bank by the water flow.

[0052] Several layers of elastic pads 22 are arranged between the wave-breaking buoyancy cabin 15 and the ecological floating bed 17 to provide a buffering effect.

[0053] Working principle: Forest cultivation areas and aquatic plant cultivation areas are set up above and at the bottom of the slope protection respectively. The plants planted in the forest cultivation area and the aquatic plant cultivation area can stabilize the soil and prevent water from eroding the soil at the bottom of the slope protection surface, thereby ensuring the anti-erosion safety of the river bank slope protection and providing a sustainable living space for animals and plants, thus realizing the ecological, beautiful, efficient and multi-functional river bank slope protection. A planting layer is arranged on the block slope protection area to provide an environment for plant growth; the stones on the block slope protection area are fixed by an upper fixing frame and a lower fixing frame, which is convenient for installing the stones. The stones can isolate the soil on the slope protection from direct contact with the water flow, thereby improving the anti-scouring ability of the slope protection; by arranging a wave-breaking component on the slope protection, when the water flow rushes toward the slope surface of the slope protection, the water-blocking plate receives the impact force of the water flow, and the water-blocking plate drives the rotating shaft to swing, thereby driving the damping plate to swing, so that the damping plate continuously stirs the damping medium in the resistance well after being subjected to force. The damping medium is water, and then the force is dissipated through the water stored at the bottom of the resistance well, thereby buffering the flowing water flow, reducing the scouring force of the water flow on the slope protection, and effectively protecting the slope protection.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
