Description

Technical Field

[0001] This invention relates to the field of ecological revetment, specifically a comprehensive ecological revetment system for river channels. Background Technology

[0002] Riverbank revetments are structures built below ground level along rivers to protect the riverbanks. As an important facility in urban rivers, revetments play an effective protective role for the rivers. In the process of modern social development, the riverbank has also become a place for people to take walks.

[0003] The existing riverbanks bear very obvious signs of human intervention, especially when the water level drops, the boundary between the bank and the water surface becomes very clear. Moreover, when the water level rises, the vegetation on the bank is easily washed away, especially the root system, resulting in damage to the ecosystem of the bank. Summary of the Invention

[0004] The purpose of this invention is to provide a comprehensive ecological revetment system for river channels to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a comprehensive ecological revetment system for river channels, comprising natural earthen slopes along both sides of a river channel, wherein a slope surface one and a slope surface two are provided on the natural earthen slopes, a horizontal lower walkway is provided between the slope surface one and the slope surface two, an upper walkway is provided on the upper side of the slope surface one, an erosion-resistant bank is provided on the slope surface two on the side closer to the river channel, a floating green vegetation layer is provided at the outer edge of the erosion-resistant bank, and a near-water protection zone is provided on the upper side of the erosion-resistant bank in the slope surface two.

[0006] Preferably, the near-water protection area includes excavating planting cavities on the second slope, setting concrete layers on the four sides of the planting cavities, installing revetment bricks at equal intervals in the planting cavities, filling the inner cavity of each revetment brick with planting soil, filling the space between adjacent revetment bricks with erosion control filler, planting a vegetation layer on the surface of the erosion control filler, and laying a layer of herbaceous vegetation on the vegetation layer planted on the surface of the erosion control filler.

[0007] Preferably, the erosion control filler includes a bottom layer of mixed soil, a middle layer of backfill soil, and a top layer of planting soil.

[0008] Preferably, a large central hole is provided at the top center of the revetment brick, and small holes are distributed around the large central hole and on the four sides of the revetment brick.

[0009] Preferably, the erosion control embankment includes steel grid piles inserted through the natural soil slope, with crushed stone filler material filled in the steel grid piles, a concrete layer poured on the crushed stone filler material, and a dense cobblestone layer laid on the concrete layer.

[0010] Preferably, the floating green plant layer includes a nylon rope net suspended on the anti-erosion shoreline, and an aquatic plant layer is laid on the nylon rope net.

[0011] Preferably, half of the aquatic plant layer is ivy and the other half is pennywort.

[0012] Preferably, both the lower and upper pedestrian walkways are paved with bluestone slabs, and guardrails are installed near the edge of the river. A stepped path is provided on the slope.

[0013] Preferably, the mixed soil material comprises a mixture of clay soil material with volcanic rock and modified slag.

[0014] In summary, the beneficial effects of this invention are:

[0015] This invention reinforces and protects the riverbank near the water by using a scour-resistant filler composed of revetment bricks and mixed soil, a middle layer of backfill soil, and a top layer of planting soil. Simultaneously, the roots and stems of the planted vegetation extend to protect the soil and water, effectively preventing soil erosion. Furthermore, a scour-resistant embankment formed by reinforced steel grids as foundation piles further strengthens the revetment, maximizing protection against erosion. A floating green plant layer is installed at the outer edge of the scour-resistant embankment. This floating green plant layer effectively conceals the contact surface between the river surface and the embankment edge, thus effectively preventing a clear boundary between the revetment and the water surface after the water level drops, greatly reducing artificial traces and making the revetment more natural.

[0026] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0027] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0028] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; they can refer to the internal communication of at least two elements or the interaction relationship of at least two elements, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0029] The following is combined Figure 1-8 The present invention will be described in detail below. For ease of description, the directions referred to below are defined as follows: the directions of up, down, left, right, front, and back mentioned below are the same as... Figure 1 The directions of front, back, left, right, up, and down in the view are consistent. Figure 1 This is a front view of the device of the present invention. Figure 1 The directions shown are consistent with the front-to-back, left-to-right, up-down directions of the device of the present invention when viewed from the front.

[0030] Please see Figure 1-8 The present invention provides an embodiment one: a comprehensive ecological revetment system for river channels, comprising natural earthen slopes 10 along both sides of the river channel, with two sloping surfaces, namely slope surface one 14 and slope surface two 16, formed on the natural earthen slopes 10. Green vegetation, such as lawns and golden privet trees, is laid on slope surface one 14. A pedestrian walkway, namely a lower pedestrian walkway 15 and an upper pedestrian walkway 11, is provided on each slope surface two 16, which is closer to the river channel. An erosion-resistant revetment 19 is provided on slope surface two 16. The revetment is reinforced to minimize erosion. A floating green layer 18 is installed at the outer edge of the erosion-resistant revetment 19. The floating green layer 18 can effectively block the contact surface between the river surface and the edge of the revetment, thereby effectively avoiding a clear boundary line between the revetment and the water surface after the water level drops. This greatly reduces the artificial traces and makes the revetment more natural. In the second slope 16, a near-water soil protection area is set on the upper side of the erosion-resistant revetment 19 to consolidate the soil and water in the near-water area and prevent it from being eroded and collapsing due to rising water.

[0031] It is worth mentioning that, in this embodiment, the aforementioned near-water protection area first excavates a cavity for planting in the slope 16, then reinforces the surrounding sidewalls of the cavity with a layer of concrete, and then installs revetment bricks 20 at equal intervals in the cavity. The revetment bricks 20 are hollow and filled with planting soil. The top center of each revetment brick 20 has a large central hole 21, which serves as the main planting opening. Small holes 22 are then set around the perimeter as secondary planting openings. The main planting opening can be used to plant large tree-like plants or large grasses, while the secondary planting openings can be used for planting other plants. Some grasses are laid in, and the small holes 22 distributed on the four sides of the revetment bricks 20 can be used for the roots of plants to pass through and extend into the backfill soil in the anti-erosion filler 24, which can effectively consolidate the soil and water. The anti-erosion filler 24 fills the gaps in the adjacent revetment bricks 20. The anti-erosion filler 24 is divided into three layers: a bottom layer of mixed soil, a middle layer of backfill soil, and a top layer of planting soil. The bottom layer of mixed soil includes a mixture of clay soil, volcanic rock, and modified slag. A layer of herbaceous vegetation 17 is laid in the planting soil on the surface of the anti-erosion filler 24.

[0032] In another embodiment, the erosion-resistant bank 19 includes steel grid piles 1901 inserted through the natural slope 10. First, a trench is dug on the side of the slope 16 near the river channel, the steel grid piles 1901 are installed in the trench, and then crushed stone filler 1902 is filled in. Then, a layer of concrete 1903 is poured on top, and finally, a dense layer of pebbles is laid on the concrete layer 1903 to cover the concrete, which can effectively reinforce and prevent erosion along the river channel.

[0033] In another embodiment, the floating green plant layer 18 includes a nylon rope net 1801 suspended on the 19, and an aquatic plant layer 1802 is set on the nylon rope net 1801. The aquatic plant layer 1802 can be set with corresponding aquatic plants according to the size of the rope net mesh, so that the roots of the plants pass through the mesh and are attached to the rope net as a whole, so that the rope net can float on the water surface and follow the water surface line to block the obvious dividing line between the revetment and the water surface.

[0034] It should be noted that the aquatic plant layer 1802 can be one or more of the following: planktonic aquatic plants, ivy, and pennywort, and can be set up according to the vegetation along the riverbank.

[0035] In another embodiment, bluestone slabs are embedded in the two sidewalks to facilitate people's walking, and guardrails 12 are installed near the edge of the river to provide installation protection. Steps 13 are provided on the slope 14 to facilitate people's access.

[0036] Example 2: When setting up a comprehensive ecological revetment system for river channels in areas with large water level fluctuations or large rainfall, the difference from Example 1 is that: a drainage pipe is first laid at the bottom in the gaps between the adjacent revetment bricks 20, and PVC pipes 23 are evenly distributed on the drainage pipe. Each PVC pipe 23 is placed between four revetment bricks 20. Finally, anti-erosion filler 24 is filled and herbaceous vegetation 17 is laid, wherein the grass of the herbaceous vegetation 17 can cover the opening of the PVC pipe 23.

[0037] By adding drainage pipes to improve drainage and concealing the drainage outlets in the grass, the erosion of the revetment when the water rises can be effectively prevented, thereby improving the stability of the revetment and making it less prone to collapse.

[0038] The above description is merely a specific embodiment of the invention, but the scope of protection of the invention is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the scope of protection of the invention. Therefore, the scope of protection of the invention should be determined by the scope defined in the claims.
