Description

Technical Field

[0001] This utility model belongs to the field of ecological governance technology, and specifically relates to a river channel structure for ecological governance. Background Technology

[0002] Ecological restoration of waterways refers to the restoration, regulation, and management of waterways using near-natural methods, aiming to restore or enhance their ecological functions while also taking into account social service functions such as flood control, water supply, landscaping, and recreation.

[0003] The existing river channel structure for ecological restoration restores the natural curvature of artificially straightened river channels to reduce water flow velocity, increase flow paths, and create diverse habitats for aquatic organisms. It is designed with a main channel and floodplain sections. Normally, water flows in the main channel, but during floods, it overflows into the floodplain, ensuring flood control capacity while restoring the ecological function of the floodplain. The existing ecological river channel structure uses ropes to install multiple ecological floating islands within the river channel during restoration. During the installation of these floating islands, anchor bolts are driven into appropriate locations to secure the ropes to the islands. This process is cumbersome, time-consuming, and labor-intensive. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the existing technology by providing a river channel structure for ecological management. Through the design of the mounting rail and sliding block, the installation, positioning, and subsequent maintenance and repair of the ecological floating bed become exceptionally flexible and convenient. The position of the floating bed can be adjusted or the entire structure can be lifted through simple mechanical operations, which facilitates the harvesting of floating bed plants (thereby removing pollutants from the water) or the maintenance and replacement of the floating bed structure itself.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a river channel structure for ecological management, including a river channel body, wherein the river channel body is provided with a compacted original soil layer, a coarse sand cushion layer and an ecological gabion layer in the height direction from bottom to top, and slope protection is provided on both sides of the river channel body, wherein the slope protection is provided with an ecological bag cushion layer and a plant fiber blanket in the height direction from bottom to top, and a floating bed installation mechanism is fixedly installed on both slope protections. The floating bed installation mechanism includes installation rails, sliding blocks, positioning seats, pull ropes, ecological floating beds, and connecting ropes. Two installation rails are fixedly installed on each slope. Sliding blocks are slidably installed inside each installation rail. Positioning seats are fixedly installed on the upper end of each sliding block. Pull ropes are fixedly installed on each positioning seat. An ecological floating bed is installed between the ends of every four adjacent pull ropes. Connecting ropes are fixedly installed between two horizontally adjacent ecological floating beds.

[0006] As a further improvement of this utility model, the floating bed installation mechanism also includes positioning holes evenly opened on each installation rail. Inside each positioning seat, two sliding frames are slidably arranged symmetrically distributed around the vertical center of the positioning seat. Two clamping blocks are fixedly installed on the side of the sliding frame away from the positioning seat. Inserted pins are fixedly installed on the clamping blocks and are respectively inserted into the adjacent positioning holes. A sliding column is fixedly installed in the middle of the positioning seat. The sliding frame is slidably connected to the adjacent sliding column. A return spring is provided between the two sliding frames located on the same positioning seat. The return spring is sleeved on the outer arc surface of the sliding column. A pull rod is fixedly installed on the side of the sliding frame away from the positioning seat.

[0007] As a further improvement of this utility model, multiple evenly distributed root plant planting beds are fixedly installed on the slope, and multiple evenly distributed planting holes are opened on each root plant planting bed; multiple connecting water pipes are opened on the slope, and multiple connecting grooves are opened in the river channel body, with the connecting water pipes connected to adjacent connecting grooves respectively; multiple evenly distributed circulating water pipes are installed on the upper side of the middle of each connecting groove; and filter screens are installed at the top of each circulating water pipe.

[0008] As a further improvement of this utility model, anti-wave blocks are fixedly installed at the upper end of the slope protection.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: Firstly, the synergistic effect of the original soil compaction layer, coarse sand cushion layer, and ecological gabion layer significantly enhances the overall stability and bearing capacity of the slope protection. The original soil compaction layer effectively improves the shear strength of the foundation soil, while the coarse sand cushion layer improves the compressibility of the foundation. Together, they reduce uneven settlement and provide a flat and solid working surface for subsequent structures. The ecological gabion layer not only further disperses the load transmitted by the superstructure and reduces the compressive stress of the base layer, but the gaps between the stones also provide space for plant root growth. Thus, through the dual mechanism of mechanical reinforcement and biological reinforcement, the shear strength of the soil is improved, and soil erosion is inhibited. This structural stability helps extend the service life of the slope protection, and its integrity and flexibility also enable it to better adapt to minor deformations of the foundation and resist flood erosion.

[0010] Secondly, the internal drainage system, consisting of connecting pipes, connecting channels, and circulating water pipes, allows water overflowing onto the slope to quickly infiltrate and flow back to the main river channel in an orderly manner during floods. This avoids direct and prolonged scouring of the slope, effectively reducing soil erosion and the risk of landslides. Simultaneously, the design restores the floodplain's water storage function during floods, slowing the peak flow and helping to reduce downstream flood risks. During dry seasons, the water stored in the connecting channels can slowly seep back in, replenishing the surrounding soil moisture, providing necessary growth for slope vegetation, maintaining the ecological and hydrological connections of the riverbank, and achieving a redistribution of water resources in time and space.

[0011] Thirdly, the design of the upper mounting rails and sliding blocks on the slope protection makes the installation, positioning, and subsequent maintenance and repair of the ecological floating bed exceptionally flexible and convenient. The position of the floating bed can be adjusted or it can be lifted as a whole through simple mechanical operations, making it easy to harvest the floating bed plants (thus removing pollutants from the water) or to repair and replace the floating bed structure itself. This modular and quick-disassembly design greatly reduces the difficulty and cost of later maintenance, enabling the ecosystem to continue to operate healthily through human intervention and ensuring the long-term effectiveness of the slope protection's ecological function.

[0015] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0016] like Figure 1 , 2As shown, the river body 101 includes a compacted soil layer 102, a coarse sand cushion layer 103, and an ecological gabion layer 104 arranged sequentially from bottom to top along the height direction of the river body 101. Both sides of the river body 101 are equipped with slope protection, and the slope protection is provided sequentially from bottom to top along the height direction of the slope protection with an ecological bag cushion layer 105 and a plant fiber blanket 106. Floating bed installation mechanisms are fixedly installed on both sides of the slope protection. The floating bed installation mechanism includes an installation rail 301, a sliding block 302, a positioning seat 303, a pull rope 310, an ecological floating bed 311, and a connecting rope 312. Two installation rails 301 are fixedly installed on each slope. A sliding block 302 is slidably installed inside each installation rail 301. A positioning seat 303 is fixedly installed at the upper end of each sliding block 302. A pull rope 310 is fixedly installed on each positioning seat 303. An ecological floating bed 311 is installed between the ends of every four adjacent pull ropes 310. A connecting rope 312 is fixedly installed between two horizontally adjacent ecological floating beds 311.

[0017] like Figure 3 As shown, the floating bed installation mechanism also includes positioning holes 306 evenly opened on each installation rail 301. Inside each positioning seat 303, two sliding frames 304 are slidably arranged symmetrically about the vertical center of the positioning seat 303. Two clamping blocks 305 are fixedly installed on the side of the sliding frame 304 away from the positioning seat 303. Insert pins are fixedly installed on the clamping blocks 305, and the insert pins are respectively inserted into the adjacent positioning holes 306. A sliding column 308 is fixedly installed in the middle of the positioning seat 303. The sliding frame 304 is slidably connected to the adjacent sliding column 308. A return spring 309 is provided between the two sliding frames 304 located on the same positioning seat 303. The return spring 309 is sleeved on the outer arc surface of the sliding column 308. A pull rod 307 is fixedly installed on the side of the sliding frame 304 away from the positioning seat 303.

[0018] like Figure 1 , 2 As shown, multiple evenly distributed root plant planting beds 201 are fixedly installed on the slope, and multiple evenly distributed planting holes 202 are opened on each root plant planting bed 201.

[0019] like Figure 4 As shown, multiple connecting water pipes 203 are provided on the slope, and multiple connecting channels 204 are provided in the river body 101. The connecting water pipes 203 are connected to the adjacent connecting channels 204 respectively. Multiple evenly distributed circulating water pipes 205 are provided on the upper side of the middle part of the connecting channels 204. A filter screen 206 is provided at the top of each circulating water pipe 205.

[0020] According to another embodiment of the present invention, such as Figure 1 , 4 As shown, wave-breaking blocks 107 are fixedly installed at the upper end of the slope protection.

[0021] In daily use, the combination of the original soil compaction layer 102, the coarse sand cushion layer 103 and the ecological gabion layer 104 can improve the bearing capacity of the foundation and reduce settlement. The original soil compaction layer 102 and the coarse sand cushion layer 103 can effectively reduce water seepage to prevent soil erosion. The ecological gabion layer 104 can change the water flow, form a shelter, and provide an attachment surface for insects and fish, which is conducive to the growth of natural plants and animals. During daily use, water that overflows onto both sides of the slope during flood season will seep into the evenly spaced connecting water pipes 203 on the slope, and then enter the connecting channel 204 inside the river body 101 through the connecting water pipes 203. This allows the connecting channel 204 to store the water that rises during the flood season, and then return it to the river channel through the circulating water pipes 205 installed on the connecting channel 204. The cooperation of the connecting water pipes 203, connecting channel 204 and circulating water pipes 205 ensures flood discharge capacity, restores the ecological function of the floodplain, and reduces the damage of water flow to the slope. Then, two mounting rails 301 are fixedly installed on both sides of the slope. Multiple sliding blocks 302 are slid into each mounting rail 301 at intervals. During the sliding process, the pull rods 307 on both sides of each sliding block 302 are pulled, so that the pull rods 307 drive the sliding frame 304 away from the positioning seat 303, and then drive the clamping blocks 305 on both sides of the positioning seat 303 away from the positioning seat 303. When the sliding block 302 moves to the designated position, the pull rods 307 on both sides of the sliding block 302 are released, so that the sliding frame 304 moves closer to the positioning seat 303 under the action of the return spring 309. Then, the sliding frame 304 drives the insert on the clamping block 305 to insert into the adjacent positioning hole 306, thereby fixing the position of the positioning seat 303. Since each positioning seat 303 is fixedly installed with a pull rope 310, the end position of the pull rope 310 is fixed. Then, an ecological floating bed 311 is fixed between the other ends of four adjacent ropes 310 on the same side. Then, two horizontally adjacent ecological floating beds 311 are connected by a connecting rope 312. Specific terrestrial or aquatic plants are planted on the ecological floating bed 311, and the plant roots and the biofilm they form are used to purify the water quality, while creating habitats and beautifying the landscape.

Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
