[0001] The utility model relates to the technical field of stepped ecological revetments, in particular to a wave-dissipating stepped ecological revetment structure for inland river revetment projects. Background Technique

[0002] The wave-dissipating stepped ecological revetment structure for inland river revetment projects is a new type of revetment technology. This structure mainly includes a wave-dissipating structure, an ecological water tank, a steel-concrete anchor beam, a rear row guide beam, a first stepped platform, a second stepped platform, backfill soil, etc. The design of this revetment structure aims to solve the problems that cannot be overcome by traditional revetment methods and has significant advantages in environmental protection and ecological restoration. For example, through the front sheet pile wall and the upper breast wall, and the rear pile foundation and the upper guide beam, a double protection is formed, which can effectively resist the destructive effect of ship traveling waves on the rear ecological water tank, provide a stable ecological environment for the rear ecological water tank, and enhance the ecology of the revetment.

It includes a slope body and ecological blocks arranged in a stepped manner along the slope body direction. On the left and right sides of the top surface of the ecological block, there are first communication grooves, and the first communication grooves are connected to the cavity in the middle of the ecological block. Reinforcement plates are symmetrically arranged in the left and right directions in the cavity, and the two reinforcement plates divide the cavity into a planting cavity and an auxiliary side cavity. The auxiliary side cavities are symmetrically arranged on both sides of the planting cavity. The reinforcement plates are provided with second communication grooves that match the first communication grooves, and the second communication grooves connect the planting cavity and the auxiliary side cavity. Adjacent ecological blocks on the left and right are fixed by limit pieces. The overall structure of the utility model is reasonably designed, has strong practicability, a wide range of uses, good self-stability of the ecological revetment structure, can better resist the impact of water flow, can well meet the requirements of bank slope protection and ecology, and has a long service life, low subsequent maintenance cost, and convenient construction process.

[0004] When the existing ecological revetment structure is used in inland river revetment projects, ecological blocks are built on the river bank, and vegetation is planted on the device. When the river bank is protected through the cooperation of the vegetation and the blocks, it is not easy to collapse and other problems. However, when the existing device is used in the inland river, the waves will continuously erode the revetment device. The long-term erosion will cause the loosening of the revetment device and the death of the vegetation on the shore, resulting in a continuous decline in the revetment effect of the revetment device. Content of the Utility Model

[0005] The purpose of this application is to provide a wave-dissipating stepped ecological revetment structure for inland river revetment projects to solve the problem that the existing device is easily continuously eroded by waves on the river bank, resulting in a decline in the revetment effect.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0007] A wave-breaking stepped ecological bank protection structure for inland river bank protection projects includes a river bank, a first slope fixedly connected to the river bank, a planting platform fixedly connected to the river bank, a second slope fixedly connected to the river bank, a sidewalk fixedly connected to the slope, a grass altar fixedly connected to the sidewalk, a blocking plate fixedly connected to the grass altar, and a wave-breaking structure provided on the river bank.

[0008] By adopting the above technical solution, when the device is used to protect the river bank, slope one is first installed at the position close to the river bank and the river surface, and then a planting platform is installed on the river bank as the first step of the bank protection structure, and then slope two is installed along the planting platform. Then, a blocking plate is installed at the end of the second slope, and then a grass platform and a sidewalk are built along the blocking plate as the second step of the bank protection structure. When waves continue to impact and erode the device, the waves can be reduced by the wave-breaking structure, thereby reducing the erosion effect of the waves on slope one, and the river bank is reinforced by the plants planted on the planting platform, and the waves are reduced in cooperation with the wave-breaking structure, so that when the device is protecting the river bank, it is less affected by the waves, and the bank protection effect of the device is better.

[0009] Furthermore, the wave-breaking structure includes a connecting rod rotatably connected to slope one, an end of the connecting rod is rotatably connected to floating plate one, and floating plate two is hinged on floating plate one.

[0010] By adopting the above technical solution, when the device is used to reduce waves, the second float first contacts the waves, blocks the waves and reduces them, and then the waves with reduced energy encounter the first float, are reduced again, and finally contact the first slope.

[0011] Furthermore, a sinking cage is fixedly connected to the floating plate, and a plurality of pebbles are filled in the sinking cage.

[0012] By adopting the above technical solution, the sinking cage carries the pebbles and sinks into the water, making the floating plate more stable.

[0013] Furthermore, a connecting rope is fixedly connected to the second floating plate, an end of the connecting rope is fixedly connected to a sinking block, and a limiting nail is fixedly connected to the sinking block.

[0014] By adopting the above technical solution, the sinking block and the limit nail on the connecting rope can extend the floating plate 2 toward the center of the river, making the floating plate 1 and the floating plate 2 more stable when dealing with wave impacts.

[0015] Furthermore, an installation groove is formed on the planting table, a planting frame is arranged on the planting table, a limiting plate is fixedly connected to the planting frame, and the limiting plate is adapted to the installation groove.

[0016] By adopting the above technical solution, the planting frame is installed on the planting table through the installation groove, and vegetation is planted therein through the gaps on the planting frame, and the roots of the vegetation are protected by the planting frame.

[0017] Furthermore, a planting groove is formed on the river bank, the planting groove is adapted to the planting table, the planting groove is funnel-shaped, and a water leakage plate is fixedly connected in the planting groove.

[0018] By adopting the above technical solution, a layer of cobblestones is filled on the water leakage plate, and then the planting groove is filled with soil, so that the water for the vegetation to survive can be preserved in the soil, and the excess water flows out from the cobblestones, so that the roots of the vegetation are not soaked.

[0019] Furthermore, a water drainage groove is formed between the planting groove and the first slope, a strainer is fixedly connected to the end of the water drainage groove, and the strainer is fixedly connected to the first slope.

[0020] By adopting the above technical solution, when the wave water hits the planting frame and the vegetation, the wave water therein will penetrate into the water leakage plate along with the soil, and the water flow is guided to the strainer through the water drainage groove.

[0021] Furthermore, a first wave protection plate is fixedly connected to the first slope, and a second wave protection plate is fixedly connected to the second slope.

[0022] By adopting the above technical solution, when the waves hit the first slope and the second slope, the first wave protection plate and the second wave protection plate can block the waves, reduce the influence of the waves on the device, and make the use of the device on the river bank more convenient.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] 1. In the present application, when the device resists wave impact, the second floating plate first contacts the wave, blocks the wave and reduces it, then the wave with reduced energy encounters the first floating plate and is reduced again, and finally contacts the first slope. At the same time, the sinking cage carries cobblestones and sinks into the water, making the first floating plate more stable. And through the sinking block and the limiting nail on the connecting rope, the second floating plate can extend towards the center of the river channel, making the first floating plate and the second floating plate more stable when resisting wave impact. When the first slope is affected by the wave, it has been reduced twice, reducing the impact and erosion of the wave on the device, reducing the impact on the river bank, and enhancing the protection ability of the device to the river bank.

[0025] 2. When planting vegetation on the device for bank protection, first fill a layer of cobblestones on the water leakage plate, then fill the planting groove with soil, then install the planting frame on the planting table through the installation groove, and plant the vegetation through the gaps on the planting frame. When the waves turn and the wave water hits the planting frame and the vegetation, the wave water will penetrate into the water leakage plate along with the soil, and the water flow will be guided to the strainer through the water drainage groove, and finally flow back into the river along the slope. This makes the root systems of the vegetation planted on the river bank not easily soaked and eroded by the wave water, makes the living environment of the vegetation milder, enables the vegetation to better protect the river bank, and reduces the erosion of the river bank by the waves.

[0033] The embodiment of this application discloses a wave-dissipating stepped ecological bank protection structure for inland river bank protection projects.

[0034] Refer to Figure 1A wave-breaking stepped ecological bank protection structure for inland river bank protection projects includes a river bank 1, a slope 1 2 is fixedly connected to the river bank 1, a planting platform 3 is fixedly connected to the river bank 1, a slope 2 4 is fixedly connected to the river bank 1, a sidewalk 6 is fixedly connected to the slope, a grass altar 5 is fixedly connected to the sidewalk 6, a blocking plate 22 is fixedly connected to the grass altar 5, and a wave-breaking structure is provided on the river bank 1.

[0035] When the device is used to protect the river bank 1, first install the slope 1 2 at the part of the river bank 1 close to the river surface, then install the planting platform 3 on the river bank 1 as the first step of the bank protection structure, and then install the slope 2 4 along the planting platform 3, and then install the blocking plate 22 at the end of the slope 2 4, and then build a grass platform 5 and a sidewalk 6 along the blocking plate 22 as the second step of the bank protection structure. When waves continue to impact and erode the device, the waves can be reduced by the wave-breaking structure, so that the erosion effect of the waves on the slope 2 is reduced, and the river bank 1 is reinforced by the plants planted on the planting platform 3, and the waves are reduced in cooperation with the wave-breaking structure, so that when the device is protecting the river bank 1, it is less affected by the waves, and the bank protection effect of the device is better.

[0036] Reference Figure 1 and Figure 2 、 Figure 4 The wave-breaking structure includes a connecting rod 11 rotatably connected to slope 1 (2). The end of connecting rod 11 is rotatably connected to floating plate 12, which is hingedly connected to floating plate 12. A sinking cage 14 is fixedly connected to floating plate 12, and is filled with pebbles. A connecting rope 15 is fixedly connected to floating plate 13. The end of connecting rope 15 is fixedly connected to a sinking block 16, which is fixedly connected to a limit pin 21.

[0037] When the device is used to reduce waves, float 2 13 first contacts the waves, blocks the waves and reduces them, then the waves with reduced energy encounter float 12, are reduced again, and finally contact slope 1 2. At the same time, the pebbles carried in the sinking cage 14 sink into the water, making float 12 more stable. The sinking block 16 and the limit nail 21 on the connecting rope 15 can extend float 2 13 toward the center of the river channel, making float 12 and float 2 13 more stable in response to wave impacts, so that slope 1 2 has been reduced twice when affected by waves, reducing the impact and erosion of the device by waves, making the river bank 1 less affected, and enhancing the device's ability to protect the river bank 1.

[0038] Reference Figure 1 and Figure 3, an installation groove is provided on the planting table 3, a planting frame 7 is arranged on the planting table 3, a limiting plate 8 is fixedly connected to the planting frame 7, and the limiting plate 8 is adapted to the installation groove. A planting groove 19 is provided on the river bank 1, the planting groove 19 is adapted to the planting table 3, the planting groove 19 is funnel-shaped, and a water leakage plate 18 is fixedly connected inside the planting groove 19. A water drainage groove 20 is provided between the planting groove 19 and the first slope 2, a leakage net 10 is fixedly connected to the end of the water drainage groove 20, and the leakage net 10 is fixedly connected to the first slope 2.

[0039] When planting vegetation on the device for bank protection, first fill a layer of cobblestones on the water leakage plate 18, then fill the planting groove 19 with soil, then install the planting frame 7 on the planting table 3 through the installation groove, and plant the vegetation through the gaps on the planting frame 7. When the waves turn and the water hits the planting frame 7 and the vegetation, the water therein will penetrate into the water leakage plate 18 along with the soil, and the water flow will be guided to the leakage net 10 through the water drainage groove 20, and finally flow back into the river along the first slope 2. This makes the root systems of the vegetation planted on the river bank 1 not easily soaked and eroded by the waves, makes the living environment of the vegetation milder, enables the vegetation to better protect the river bank 1, and reduces the erosion of the waves on the river bank 1.

[0040] Refer to Figure 1 , a first wave protection board 9 is fixedly connected to the first slope 2, and a second wave protection board 17 is fixedly connected to the second slope 4.

[0041] When the waves hit the first slope 2 and the second slope 4, the first wave protection board 9 and the second wave protection board 17 can block the waves, reduce the impact of the waves on the device, and make the use of the device on the river bank 1 more convenient.

[0042] Working principle: When using this device to protect the river bank 1, first install the first slope 2 at the part of the river bank 1 close to the river surface, then install the planting table 3 on the river bank 1 as the first step of the bank protection structure, then install the second slope 4 along the planting table 3, then install the blocking board 22 at the end of the second slope 4, and then build the grassland 5 and the sidewalk 6 along the blocking board 22 as the second step of the bank protection structure;

[0043] When the device responds to wave impact, the second floating board 13 first contacts the waves, blocks the waves and cuts them down. Then the waves with reduced energy encounter the first floating board 12 and are cut down again. Finally, they contact the first slope 2. At the same time, the sinking cage 14 carries cobblestones and sinks into the water, making the first floating board 12 more stable. And through the sinking block 16 and the limiting nail 21 on the connecting rope 15, the second floating board 13 can extend towards the center of the river channel, making the first floating board 12 and the second floating board 13 more stable when responding to wave impact. When the first slope 2 is affected by the waves, it has been cut down twice, reducing the impact and erosion of the waves on the device and making the impact on the river bank 1 less, strengthening the protection ability of the device for the river bank 1;

[0044] When planting vegetation on the device for bank protection, first fill a layer of cobblestones on the water leakage plate 18, then fill the planting groove 19 with soil, then install the planting frame 7 on the planting table 3 through the installation groove, and plant the vegetation through the gaps on the planting frame 7. When the waves turn and the wave water hits the planting frame 7 and the vegetation, the wave water therein will penetrate into the water leakage plate 18 along with the soil, and the water flow will be guided to the strainer 10 through the water drainage groove 20, and finally flow back into the river along the slope 1-2. This makes the root systems of the vegetation planted on the river bank 1 not easily soaked and eroded by the wave water, makes the living environment of the vegetation milder, enables the vegetation to better protect the river bank 1, and reduces the erosion of the wave on the river bank 1.
