Description

Technical Field

[0001] The invention belongs to the technical field of ecological revetment, and in particular is a vertical revetment ecological buffer zone system which is adaptive to water level changes. Background Art

[0002] Vertical revetments mainly use engineering measures to build riverbanks or lakebanks into nearly vertical structures to prevent soil erosion, protect infrastructure and improve the landscape. While having a protective function, it promotes the recovery of biodiversity and ecosystems. However, since water flows directly scour the revetment structure, it is easy to cause soil erosion. Hard materials such as concrete slabs or reinforced gabions will crack and peel due to long-term impact of water flows, reducing the protective effect of the revetment, causing the entire revetment structure to gradually lose support and increase the risk of collapse. Therefore, revetment buffer strips are needed to reduce the direct scouring of the revetment structure by water flows.

[0003] In the prior art, for example, the invention patent with publication number CN108035303B adopts an anti-scour ecological bank protection structure which can protect the natural bank slope through protection blocks, thereby reducing the impact force of water flow to a certain extent. However, since the protection blocks cannot be adjusted autonomously with the change of water level, when the water level rises, the water flow will still pass over the protection blocks and directly scour the soil around the bank protection, causing impact erosion.

[0004] Therefore, it is necessary to provide a vertical bank protection ecological buffer zone system that is adaptive to water level changes to solve the problems raised in the above background technology. Summary of the invention

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a vertical revetment ecological buffer zone system that is adaptive to water level changes, comprising: two slope protection frames arranged in parallel, and the two slope protection frames are distributed perpendicular to the revetment direction; pillars, which are vertically arranged and fixed on the slope protection frames; connecting chains, which are connected to each of the pillars; and buffer slope protection units, which are multiple arranged and arranged parallel to the revetment, and the two ends of the buffer slope protection units are connected to the pillars through connecting chains.

[0006] Preferably, the buffer slope protection unit is composed of a front floating belt and a rear floating belt, a sprocket is fixed to the upper end of each support, and the connecting chain is wound around the sprocket in a V shape.

[0007] Preferably, the front floating belt comprises: a first pontoon, which is a plurality of pontoons arranged in an array, with a first chain connected between each of the first pontoons; a fixed frame fixed in the first pontoon; a sliding sleeve slidably connected to both ends of the fixed frame, with each of the sliding sleeves being obliquely hinged with a compression spring, one end of the compression spring being connected to the fixed frame; a central axis rod horizontally connected in the first pontoon, with one end of the central axis rod being connected to one of the sliding sleeves; two side axis rods symmetrically distributed, with one end of each of the two side axis rods being connected to the other sliding sleeve; and fixed plates distributed on both sides of the first pontoon, with each of the fixed plates being correspondingly connected to the other end of the central axis rod and the side axis rod respectively.

[0008] Preferably, the rear floating belt includes: a plurality of second pontoons arranged in an array, with second chains connected between each of the second pontoons; a central axis disk rotatably connected in the second pontoons, with sealing plates fixed on both sides of the interior of the second pontoons, and rollers rotatably connected on the sealing plates; a guide rod slidably connected in the roller, with one end of the guide rod hinged to the central axis disk; and a tension spring, with both ends of the tension spring respectively connected to the guide rod.

[0009] Preferably, the first buoys in the front floating belt and the second buoys in the rear floating belt are staggered.

[0010] Preferably, an inner connecting plate is fixed on each of the rollers in the second buoy, an anti-slip sleeve is arranged parallel to one side of the inner connecting plate, the anti-slip sleeve is slidably sleeved outside the guide rod, and a plurality of limit springs are connected between the anti-slip sleeve and the rollers.

[0011] Preferably, the second chains on both sides of the second buoy cause the two guide rods to gradually be distributed in a straight line during reverse traction, at which time the second buoy is inclined relative to the guide rod, and the inclination angle between the second buoy and the guide rod is no more than 25°.

[0012] Preferably, the second buoys in the rear floating belt are connected in a left-right symmetrical distribution or in a left-right stepped distribution.

[0013] Preferably, the second buoys of two rear floating belts in the buffer slope protection unit away from the revetment direction are connected in a left-right stepped distribution; while the second buoys of the remaining rear floating belts close to the revetment direction are connected in a left-right symmetrical distribution.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: in the present invention, two slope protection frames are installed in the vertical direction of the revetment, and buffer slope protection units are distributed laterally between the slope protection frames. Multiple buffer slope protection units can form a multi-level protection system, thereby enhancing the overall stability of the revetment. Among them, the buffer slope protection unit can intercept the impact of the water flow through the first buoy and the second buoy in the front floating belt and the rear floating belt, thereby effectively dispersing the impact of the water flow on the revetment; and the front floating belt and the rear floating belt are connected in a V-shape by a connecting chain, so that the front floating belt and the rear floating belt can float under low water level and normal water level conditions. On the water surface, it ensures that the impact force can be effectively dispersed when the water flows through; when the water level rises unexpectedly, the front floating belt can float with the change of water level, and the rear floating belt gradually sinks into the water due to the traction force of the connecting chain. On the one hand, the height difference between the front floating belt and the rear floating belt can form a natural diversion effect, so that the water flow is further dispersed when passing through, reducing the overall impact intensity. On the other hand, after the rear floating belt sinks into the water, a certain bypass effect will be generated when the water flows through, slowing down the water flow speed, and the rear floating belt effectively disperses the underwater impact force, further improving the safety and reliability of the bank protection structure.

DETAILED DESCRIPTION

[0016] See also Figure 1-Figure 7In an embodiment of the present invention, a vertical bank protection ecological buffer zone system that is adaptive to water level changes includes: a slope protection frame 1, which is two parallelly arranged slope protection frames 1, and the two slope protection frames 1 are distributed perpendicular to the bank protection direction; pillars 11 are vertically arranged and fixed on the slope protection frame 1; a connecting chain 12 is connected to each of the pillars 11; a plurality of buffer slope protection units 2 are arranged and distributed and arranged parallel to the bank protection, and both ends of the buffer slope protection unit 2 are connected to the pillars 11 through the connecting chain 12, wherein the space between the buffer slope protection units 2 can be used to plant water-resistant plants, such as reeds, calamus, etc., which can not only strengthen the soil, but also purify water quality and improve the ecological environment, and the spacing between adjacent pillars 11 on the slope protection frame 1 should be maintained at about 5m, so as to ensure the coordinated layout between the buffer slope protection units 2, reduce the load of a single pillar 11, and thus improve the impact resistance of the entire system.

[0017] In this embodiment, the buffer slope protection unit 2 is composed of a front floating belt 3 and a rear floating belt 4. A sprocket 13 is fixed to the upper end of each pillar 11. The connecting chain 12 is V-shaped and wound around the sprocket 13. In the case of low water level and normal water level, the front floating belt 3 and the rear floating belt 4 can float on the water surface to ensure that the impact force can be effectively dispersed when the water flows through. At this time, the dual design of the front floating belt 3 and the rear floating belt 4 can better disperse the force of the water flow and reduce the impact of direct impact on the revetment; in the case of high water level changes, the front floating belt 3 and the rear floating belt 4 can effectively disperse the impact force when the water flows through. The dynamic belt 3 can still float with the change of water level, and the rear floating belt 4 is gradually sunk into the water due to the traction of the connecting chain 12, so that a certain height difference is reached between the front floating belt 3 and the rear floating belt 4 to form a natural diversion effect, so that the water flow is further dispersed when passing through. It should be noted that the overall buoyancy of the front floating belt 3 is significantly higher than the overall buoyancy of the rear floating belt 4. For example, the first buoy 31 in the front floating belt 3 can adopt a low-density hollow structure (such as polymer material) to ensure that even if the water level rises, the buoyancy can still maintain the floating state of the front floating belt 3.

[0018] As a preferred embodiment, the front floating belt 3 includes: a plurality of first buoys 31 arranged in an array, each of which is connected to a first chain 32; a fixing frame 33 fixed in the first buoy 31; a sliding sleeve 34 slidably connected to both ends of the fixing frame 33, each of which is obliquely hinged with a compression spring 35, one end of which is connected to the fixing frame 33; a central axis rod 36 horizontally connected to the first buoy 31, one end of which is connected to one of the sliding sleeves 34; and two side axis rods 37 symmetrically distributed, one end of each of which is connected to the other side axis rod 37. The sliding sleeve 34 is connected; the fixed plates 38 are distributed on both sides of the first buoy 31, and each of the fixed plates 38 is respectively connected to the other end of the central axis rod 36 and the side axis rod 37. Therefore, when the front floating belt 3 is impacted by the water flow, the impact between adjacent first buoys 31 causes the first chain 32 to be completely straightened and extended. At this time, the two side axis rods 37 and the central axis rod 36 in the first buoy 31 gradually slide out of the first buoy 31 under the action of traction, and the compression spring 35 is in a compressed state. The multiple first buoys 31 can be distributed in an arc shape (when the front floating belt 3 is not impacted by the water flow, the first buoys 31 are distributed in a straight line), thereby forming an impact interception of the water flow.

[0019] In this embodiment, the rear floating belt 4 includes: a second pontoon 41, which is a plurality of pontoons 41 arranged in an array, and a second chain 42 is connected between each of the second pontoons 41; a central axis plate 43, which is rotatably connected in the second pontoon 41, and sealing plates 44 are fixed on both sides of the interior of the second pontoon 41, and rollers 45 are rotatably connected to the sealing plates 44; a guide rod 46, which is slidably connected in the roller 45, and one end of the guide rod 46 is hinged to the central axis plate 43; a tension spring 47, both ends of which are respectively connected to the guide rod 46, so that when the rear floating belt 4 is impacted by the water flow, the guide rod 46 in the second pontoon 41 is gradually slid out of the second pontoon 41 under the action of traction, and a relative deflection is generated between the central axis plate 43 and the second pontoon 41, and the roller 45 on the sealing plate 44 can be deflected accordingly, so that the guide rod 46 gradually tilts relative to the second pontoon 41 during the outward sliding, and the tension spring 47 is in a stretched state at this time until the two guide rods 46 remain in the same straight line.

[0020] In this embodiment, the first buoy 31 in the front floating belt 3 and the second buoy 41 in the rear floating belt 4 are staggered in distribution, thereby improving the impact interception effect on the water flow.

[0021] In this embodiment, an inner connecting plate 5 is fixed on each of the rollers 45 inside the second buoy 41, and an anti-skid sleeve 51 is arranged in parallel on one side of the inner connecting plate 5. The anti-skid sleeve 51 is slidably sleeved outside the guide rod 46, and a plurality of limit springs are connected between the anti-skid sleeve 51 and the rollers 45. There is a strong anti-skid friction effect between the anti-skid sleeve 51 and the guide rod 46, which can provide instantaneous braking force to the guide rod 46 through friction during the rapid sliding displacement of the guide rod 46, thereby preventing the guide rod 46 from slipping or losing control due to excessive speed.

[0022] As a preferred embodiment, the second chains 42 on both sides of the second buoy 41 make the two guide rods 46 gradually distributed in a straight line during reverse traction. At this time, the second buoy 41 is inclined relative to the guide rod 46, and the inclination angle between the second buoy 41 and the guide rod 46 is not greater than 25°.

[0023] In the present embodiment, the second pontoons 41 in the rear floating belt 4 are connected in a left-right symmetrical distribution or a left-right stepped distribution. When the second pontoons 41 are connected in a left-right symmetrical distribution, the rear floating belt 4 is arranged in a straight line as a whole, which can form a double impact interception with the first pontoons 31 in the front floating belt 3; and when the second pontoons 41 are connected in a left-right stepped distribution, the rear floating belt 4 is arranged in a diagonal line as a whole, which can guide the vertical impact water flow of the revetment to one side, so that the water flow generates lateral flow when passing through, thereby reducing the direct impact on the revetment.

[0024] In this embodiment, the second pontoons 41 of two of the rear floating belts 4 in the buffer slope protection unit 2 away from the revetment direction are connected in a left-right stepped distribution; and the second pontoons 41 of the remaining rear floating belts 4 close to the revetment direction are connected in a left-right symmetrical distribution, so that the oblique layout of the rear floating belt 4 can be fully utilized for diversion at a position away from the revetment, and the vertical impact water flow is guided to one side to reduce the direct impact on the revetment; and at a position close to the revetment direction, the linear layout of the rear floating belt 4 is utilized to cooperate with the first pontoon 31 in the front floating belt 3 to form a double impact interception.

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.
