An ecological restoration landscape area along a seasonal river

Abstract

This invention discloses a seasonal riverside ecological restoration landscape area, comprising an ecological restoration landscape area, a dam body between the ecological restoration landscape area and the river, and an inlet gate and an outlet gate sequentially installed along the river direction on the dam body. A partition dam is installed on the side of the dam body facing inwards from the ecological restoration landscape area, with the inlet and outlet gates located on opposite sides of the partition dam. A dividing dam is installed between the end face of the partition dam and the inner wall of the ecological restoration landscape area. The dividing dam and the partition dam divide the ecological restoration landscape area and the dam body into a pollution interception area, a sedimentation and adsorption landscape area, and an aquatic organism aquaculture area. This allows for water storage during the high-water season to divert floodwaters and prevent flooding disasters, and during the low-water season, the water can be used for irrigation or returned to the river channel to help restore the river's ecological balance, while simultaneously meeting landscape requirements.

Description

Technical Field

[0001] This invention relates to the technical field of river ecological restoration and landscape creation, and in particular to a seasonal riverside ecological restoration landscape area. Background Technology

[0002] Seasonal rivers, also known as intermittent or seasonal rivers, are rivers that dry up and have exposed riverbeds during the dry season, but flow again during the wet season, sometimes even causing floods. These rivers typically flow through hot, arid regions and have relatively small annual average flows, but can experience large flood peaks due to torrential rains and snowmelt. Currently, excessive water diversion and damming by humans are turning perennial rivers into seasonal rivers; many of my country's inland rivers are seasonal.

[0003] River embankments are built along both sides of rivers for flood control and water flow guidance. While the construction of these embankments is costly, their function is relatively singular. Currently, there is still a lack of reasonable solutions to comprehensively utilize these embankments to meet needs in terms of landscape, ecology, irrigation, and flood discharge. Therefore, we propose a seasonal riverside ecological restoration landscape area. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention provides a seasonal riverbank ecological restoration landscape area that can store water during the high-water season to divert floodwaters from the river and prevent flooding disasters, and use the water for irrigation or return it to the river channel during the dry season to help restore the ecological balance of the river, while also meeting the needs of the landscape.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a seasonal riverbank ecological restoration landscape area, comprising ecological restoration landscape areas set and constructed along the flow direction of the river on both sides of the riverbank, wherein a dam is set between the ecological restoration landscape area and the river, and an inlet gate and an outlet gate are sequentially installed on the dam along the river direction, wherein a partition dam is set on the side of the dam facing the interior of the ecological restoration landscape area, and the inlet gate and the outlet gate are respectively located on both sides of the partition dam, wherein a dividing dam is set between the end face of the partition dam and the inner wall of the ecological restoration landscape area, wherein the dividing dam and the partition dam form a "T" shaped structure and divide the ecological restoration landscape area and the dam into a pollution interception area, a sedimentation and adsorption landscape area, and an aquatic organism aquaculture area.

[0006] As a preferred embodiment of the present invention, the dam body is provided with an inlet and an outlet at both ends of the river, located upstream and downstream respectively. The inlet gate and the upstream inlet are connected or disconnected by opening or closing. The outlet gate and the downstream outlet are connected or disconnected by opening or closing.

[0007] As a preferred technical solution of the present invention, the dividing dam is provided with two water inlets for water supply and flow. The two water inlets are located on both sides of the dividing dam and correspond to the pollution interception area and the aquatic organism breeding area, respectively.

[0008] As a preferred embodiment of the present invention, coarse and fine screens are arranged at intervals along the water flow direction in the interception zone. The coarse screens are arranged horizontally on the plane, and the fine screens are arranged in a bent manner on the plane.

[0009] As a preferred embodiment of the present invention, a viewing corridor is provided on the top of the dividing dam and the partition wall dam, and a corridor is provided between the top of the partition wall dam and the ecological restoration landscape area, and the corridor is set according to the positions of the coarse grid and the fine grid.

[0010] As a preferred technical solution of the present invention, the sedimentation and adsorption landscape area is provided with a front emergent plant landscape belt, a floating plant landscape belt, a submerged plant landscape belt and a rear emergent plant landscape belt in sequence along the water flow direction. The front emergent plant landscape belt and the rear emergent plant landscape belt span the sedimentation and adsorption landscape area in a plane. The floating plant landscape belt is set in multiple groups and distributed alternately.

[0011] As a preferred technical solution of the present invention, a purification and interception dam is provided in the water inlet corresponding to the aquatic organism breeding area. The purification and interception dam consists of a top plate and a front baffle, a rear baffle, and two side plates fixed to the lower surface of the top plate. The two side plates are respectively fixed to the two ends of the front baffle and the rear baffle. The top plate, the front baffle, the rear baffle, and the two side plates form an isosceles trapezoidal shape and block the water inlet of the corresponding aquatic organism breeding area. The front baffle and the rear baffle are provided with evenly distributed permeable holes.

[0012] As a preferred embodiment of the present invention, the top plate, front baffle, rear baffle and side plate of the purification interception dam are reinforced concrete structural walls.

[0013] As a preferred embodiment of the present invention, four sets of gabion mesh are provided between the two side plates, and a non-woven geotextile separation layer is provided between two adjacent gabion meshes. The non-woven geotextile separation layer consists of three sets, with the middle set filled with absorbent particles and the other two sets filled with fine sand and gravel. A coarse sand and gravel layer is filled between the front baffle and the rear baffle.

[0014] As a preferred technical solution of the present invention, aquatic organisms suitable for survival are cultivated in the aquatic organism breeding area based on water sample information.

[0015] Compared with the prior art, the beneficial effects that this invention can achieve are:

[0016] 1. By opening the inlet gate and closing the outlet gate during the high-water season of seasonal rivers, the water in the river enters the ecological restoration landscape area through the inlet for water storage, which can divert floodwaters from the river and prevent flood disasters.

[0017] 2. During the dry season of seasonal rivers, the relatively clean water in the aquatic organism breeding area can be used directly for irrigation. Alternatively, by opening the outlet gate and closing the inlet gate, the water and aquatic organisms in the aquatic organism breeding area can flow back into the river through the outlet to help restore the ecological balance of the river.

[0018] 3. The landscape features a front emergent plant belt, a floating plant belt, a submerged plant belt, and a rear emergent plant belt, along with aquatic organisms raised in the aquatic life breeding area. These features provide opportunities for viewing and fishing. Visitors can walk along the viewing corridors over the ecological restoration landscape area, thus fulfilling the landscape requirements.

[0019] 4. When water enters the ecological restoration landscape area, it is blocked by coarse and fine screens. The water is fully degraded and adsorbed by the plants in the landscape area through sedimentation. The water is then filtered through the purification interception dam to achieve purification and restoration of the water. Attached Figure Description

[0027] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0028] Example:

[0029] like Figure 1 - Figure 6 As shown, this embodiment proposes a seasonal riverbank ecological restoration landscape area, including an ecological restoration landscape area 1 set up and constructed along the river flow direction on both sides of the riverbank. A dam 2 is set between the ecological restoration landscape area 1 and the river. An inlet gate 3 and an outlet gate 4 are installed sequentially along the river direction on the dam 2. A partition wall dam 5 is set on the side of the dam 2 facing the interior of the ecological restoration landscape area 1. The inlet gate 3 and the outlet gate 4 are located on both sides of the partition wall dam 5. A dividing dam 6 is set between the end face of the partition wall dam 5 and the inner wall of the ecological restoration landscape area 1. The dividing dam 6 and the partition wall dam 5 form a "T" shape structure, dividing the ecological restoration landscape area 1 and the dam 2 into a pollution interception area 7, a sedimentation and adsorption landscape area 8, and an aquatic organism aquaculture area 9.

[0030] In a preferred embodiment of the present invention, the dam body 2 is provided with an inlet 21 and an outlet 22 at the upstream and downstream ends of the river, respectively. The inlet gate 3 and the upstream inlet 21 of the river are connected or disconnected by opening or closing the inlet 21. The outlet gate 4 and the downstream outlet 22 of the river are connected or disconnected by opening or closing the outlet 22.

[0031] In a preferred embodiment of the present invention, coarse screens 71 and fine screens 72 are arranged at intervals along the direction of water flow in the pollution interception zone 7. The coarse screens 71 are arranged horizontally on the plane, and the fine screens 72 are arranged bent on the plane. A viewing corridor 10 is provided on the top of the dividing dam 6 and the partition wall dam 5. A corridor 11 is provided between the top of the partition wall dam 5 and the ecological restoration landscape area 1. The corridor 11 is arranged according to the positions of the coarse screens 71 and the fine screens 72.

[0032] Specifically, coarse screens 71 and fine screens 72 are installed at intervals in the pollution interception zone 7. The water entering the pollution interception zone 7 passes through the coarse screens 71 and fine screens 72 in sequence, intercepting larger and smaller debris in the water, respectively, to prevent debris from entering the next stage of sedimentation and adsorption landscape zone 8. Furthermore, a corridor 11 is set according to the position of the coarse screens 71 and fine screens 72 to facilitate the cleaning of the intercepted debris.

[0033] In a preferred embodiment of the present invention, the sedimentation and adsorption landscape area 8 is provided with a front emergent plant landscape belt 81, a floating plant landscape belt 82, a submerged plant landscape belt 83 and a rear emergent plant landscape belt 84 in sequence along the water flow direction. The front emergent plant landscape belt 81 and the rear emergent plant landscape belt 84 span the sedimentation and adsorption landscape area 8 in a plane. The floating plant landscape belt 82 is set in multiple groups and distributed alternately.

[0034] Specifically, the water entering the sedimentation and adsorption landscape area 8 passes sequentially through the front emergent plant landscape belt 81, the floating plant landscape belt 82, the submerged plant landscape belt 83, and the rear emergent plant landscape belt 84. The floating plant landscape belt 82 is arranged at intervals to form a meandering channel, which allows the water entering the sedimentation and adsorption landscape area 8 to be fully sedimented and adsorbed and degraded, effectively purifying the water. The front emergent plant landscape belt 81, the floating plant landscape belt 82, and the rear emergent plant landscape belt 84 meet the landscape requirements. When the water volume in the sedimentation and adsorption landscape area 8 is small, the submerged plant landscape belt 83 becomes visible.

[0035] In a preferred embodiment of the present invention, the dividing dam 6 has two water inlets 61 for water supply. The two water inlets 61 are located on both sides of the dividing wall dam 5 and correspond to the pollution interception area 7 and the aquatic organism breeding area 9, respectively. A purification interception dam 62 is provided in the water inlet 61 corresponding to the aquatic organism breeding area 9. The purification interception dam 62 consists of a top plate 621 and a front baffle 622, a rear baffle 623, and two side plates 624 fixed to the lower surface of the top plate 621. The two side plates 624 are fixed to the two ends of the front baffle 622 and the rear baffle 623, respectively. The top plate 621, the front baffle 622, the rear baffle 623, and the... Two side plates 624 form an isosceles trapezoidal shape and block the water inlet 61 of the corresponding aquatic organism breeding area 9. The front baffle 622 and the rear baffle 623 are both provided with evenly distributed permeable holes 625. Four sets of gabion nets 626 are set between the two side plates 624. A non-woven geotextile separation layer 627 is set between two adjacent gabion nets 626. There are three sets of non-woven geotextile separation layers 627, and the middle set is filled with absorbent particles 628. The other two sets of non-woven geotextile separation layers 627 are filled with fine gravel layers 629. A coarse gravel layer 6210 is filled between the front baffle 622 and the rear baffle 623.

[0036] Specifically, the top plate 621, front baffle 622, rear baffle 623 and side plate 624 that make up the purification interception dam 62 are reinforced concrete structural walls. Water flows into the purification interception dam 62 through the permeable holes 625. The water is filtered through the coarse gravel layer 6210, the fine gravel layer 629 and the adsorbent particles 628, making the water entering the aquatic organism breeding area 9 relatively clean.

[0037] In a preferred embodiment of the present invention, aquatic organisms suitable for survival are cultivated in the aquatic organism breeding area 9 based on water sample information;

[0038] Specifically, water samples are collected and tested in aquatic organism breeding area 9. After testing, suitable aquatic organisms are raised in the water inside aquatic organism breeding area 9. The aquatic organisms meet the landscape requirements and can be returned to the river with the water after cultivation to help restore the ecological balance of the river.

[0039] Working principle and usage process of this invention:

[0040] First, an ecological restoration landscape area 1 is set up on both sides of the river. On the ecological restoration landscape area 1, a dam body 2, a partition wall dam 5, and a dividing dam 6 are poured. At the inlet 21 and outlet 22 of the dam body 2, inlet gate 3 and outlet gate 4 are installed respectively. A purification interception dam 62 is installed in one of the water passages 61 of the dividing dam 6. In the sedimentation and adsorption landscape area 8, a front emergent plant landscape belt 81, a floating plant landscape belt 82, a submerged plant landscape belt 83, and a rear emergent plant landscape belt 84 are planted. Finally, a viewing corridor 10 and a corridor 11 are laid. Once the construction is completed, it can be put into use.

[0041] During the high-water season of seasonal rivers, the inlet gate 3 is opened and the outlet gate 4 is closed. The water in the river enters the ecological restoration landscape area 1 through the inlet 21 for water storage, which can divert floodwaters from the river and prevent flood disasters.

[0042] After the water enters the ecological restoration landscape area 1, it passes through coarse screen 71 and fine screen 72 in sequence to intercept larger and smaller debris in the water, preventing debris from entering the next stage of sedimentation and adsorption landscape area 8. Then, the water enters the sedimentation and adsorption landscape area 8 through the corresponding inlet 61. The water passes through the front emergent plant landscape belt 81, floating plant landscape belt 82, submerged plant landscape belt 83 and rear emergent plant landscape belt 84 in sequence. Among them, the floating plant landscape belt 82 is arranged at intervals to form a meandering channel, so that the water entering the sedimentation and adsorption landscape area 8 can be fully sedimented and adsorbed and degraded, effectively purifying the water. Subsequently, the water will infiltrate into the aquatic organism breeding area 9 through the purification interception dam 62. During this process, it is filtered by the coarse gravel layer 6210, the fine gravel layer 629 and the adsorbed particulate matter 628, so that the water entering the aquatic organism breeding area 9 is relatively clean. Finally, aquatic organisms suitable for survival are raised in the aquatic organism breeding area 9.

[0043] When the seasonal river reaches its dry season, the relatively clean water in the aquatic organism breeding area 9 can be used directly for irrigation. Alternatively, the water and aquatic organisms in the aquatic organism breeding area 9 can be returned to the river through the outlet 22 by opening the outlet gate 4 and closing the inlet gate 3 to help restore the ecological balance of the river.

[0044] In practical use, during the high water season, the front emergent plant landscape belt 81, the floating plant landscape belt 82, and the rear emergent plant landscape belt 84 are exposed above the water surface. During the low water season, the submerged plant landscape belt 83 is exposed above the water surface. The aquatic organisms raised in the aquatic organism breeding area 9 can be viewed and fished. The viewing corridor 10 allows people to walk on the ecological restoration landscape area 1, thus meeting the needs of the landscape.

[0045] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the foregoing embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
