[0041] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] refer to Figure 1-Figure 8 As shown, the present invention provides an ecological slope protection structure for river channel management, which is arranged in a foundation trench 10 excavated at a river channel bank slope. The ecological slope protection structure includes a slope protection frame 20 and a vegetation foundation 31.

[0043] The slope protection frame 20 includes a top panel 22, a bottom panel 23, a back frame 24 and two side panels 21; wherein the two side panels 21 are arranged opposite to each other, the top panel 22 is connected between the upper parts of the two side panels 21, the bottom panel 23 is connected between the lower parts of the two side panels 21, and the back frame 24 is connected between the two sides of the two side panels 21 away from the river channel; the front end surfaces of the side panels 21, the top panel 22 and the bottom panel 23, i.e., the end surfaces facing the river channel, are slope surfaces in a coplanar state. A first baffle 221 folded downward is provided at one end of the top panel 22 facing the river channel, and a second baffle 231 folded upward is provided at one end of the bottom panel 23 facing the river channel, and the top surface height of the second baffle 231 is higher than the preset water level line of the river channel. The bottom plate 23 of the slope protection frame 20 is used to connect with the bottom wall 11 of the base trench 10 to achieve the connection between the slope protection frame 20 and the base trench 10; the back frame plate 24 is a square frame structure, that is, there is a hollow opening structure on the back frame plate 24. A preset gap D is left between the slope protection frame 20 and the side wall 12 of the base trench 10, that is, the back frame plate 24 does not fit the side wall 12 of the base trench 10.

[0044] The vegetation slope protection 30 includes a vegetation foundation 31; the vegetation foundation 31 includes a base plate 311 and a plurality of groove plates 312. The base plate 311 is located inside the slope protection frame 20 and connected between the top panel 22 and the bottom panel 23. Specifically, the upper part of the base plate 311 is attached to the inner wall of the first baffle 221 on the side away from the river channel, and the lower part of the base plate 311 is attached to the inner wall of the second baffle 231 on the side away from the river channel. The front end surface of the base plate 311, i.e., the end surface facing the river channel, is parallel to the slope surface of the slope protection frame 20. Through the arrangement of the first baffle 221 and the second baffle 231, the convenience and stability of the connection between the base plate 311 and the top panel 22 and the bottom panel 23 are achieved, and the base plate 311 is reliably limited. The connection method between the base plate 311 and the first baffle 221 and the second baffle 231 includes but is not limited to bolt connection. A plurality of slot plates 312 are connected to the end surface of the base plate 311 facing the river channel at intervals, thereby forming a plurality of planting slots 313 between the vegetation base 31 and the slope protection frame 20; each planting slot 313 is planted with vegetation 32. It can be understood by those skilled in the art that the planting slots 313 can be first filled with planting soil, and then grass seeds can be sown, shrubs can be planted, or turf can be spread at a suitable planting time; or vegetation bags filled with planting soil and vegetation seeds can be directly laid.

[0045] The inner cavity of the slope protection frame 20 is filled with earth when the foundation trench 10 is excavated; further, the vegetation foundation 31 is connected to the slope protection frame 20, so that the slope protection frame 20 forms an inner cavity with only a hollow opening on the back frame plate 24; after the slope protection frame 20 and the vegetation foundation 31 are installed, earth is filled into the inner cavity of the slope protection frame 20 from the hollow opening on the back frame plate 24. The preset gap D between the slope protection frame 20 and the side wall 12 of the foundation trench 10 is also filled with earth when the foundation trench 10 is excavated. Thus, an ecological slope protection structure is set in the excavated foundation trench 10 at the river bank slope.

[0046] Furthermore, the side panel 21, the top panel 22, the bottom panel 23, the back frame panel 24, the base plate 311 and the trough plate 312 are all composite waterproof panels; the composite waterproof panels have good anti-seepage properties, deformation resistance, corrosion resistance and water erosion resistance, which can prevent the mud on the river bank from being washed into the river without affecting the ecological environment of the river; the processing and manufacturing of the composite waterproof panels are simple and fast, which reduces the construction difficulty and construction cost of river management.

[0047] It should be noted that river management is usually carried out in sections. First, a foundation trench 10 is excavated in a construction section of a preset length, and then multiple slope protection frames 20 and the vegetation foundations 31 thereon are installed one by one in the foundation trench 10 along the length direction of the river and connected to each other. Then, backfilling and planting of vegetation 32 are carried out to form an ecological slope protection and improve the natural landscape of the river.

[0048] The above-mentioned schematic embodiment simplifies the river slope protection structure through the specific arrangement of the slope protection frame 20 and the vegetated slope protection 30, thereby simplifying the river slope protection construction process, reducing the construction difficulty and cost, and improving the construction efficiency; compared with the traditional concrete slope protection structure, this embodiment can reduce the polluting elements brought to the water environment by solid protective materials such as concrete, significantly reduce the negative impact of the slope protection on the river ecological environment, and realize the rapid forming of the river slope protection.

[0049] refer to Figure 4 , Figure 5 As shown, in some embodiments, the top panel 22 and the two side panels 21, the bottom panel 23 and the two side panels 21, and the back frame panel 24 and the two side panels 21 are all connected by a mortise and tenon structure; the mortise and tenon structure includes a mortise portion 26 (also called a mortise groove) and a tenon portion 27 (also called a tenon head); Figure 5 The middle side panel 21 is provided with a mortise 26, the top panel 22, the bottom panel 23, and the back frame panel 24 is provided with a tenon 27 adapted thereto, but this is not limited thereto, and the positions of the mortise 26 and the tenon 27 are interchangeable. The top panel 22 and the bottom panel 23 are horizontally inserted between the two side panels 21 in a direction away from the river channel, and the back frame panel 24 is vertically inserted between the two side panels 21, thereby realizing convenient assembly and connection between the various components of the slope protection frame 20. Moreover, through the assembly setting of the slope protection frame 20, the slope protection frame 20 can be installed in parts in the base trench 10; specifically, the bottom panel 23 is first inserted into the two side panels 21 and placed in the base trench 10 together, and then the top panel 22 is inserted into the two side panels 21, and then the vegetation foundation 31 is installed into the slope protection frame 20 from the side of the slope protection frame 20 away from the river channel and connected to the slope protection frame 20, and then the back frame plate 24 is inserted into the two side panels 21; thereby, the transportation convenience is improved, and the construction difficulty of the overall transportation and hoisting of the slope protection frame 20 and the vegetation foundation 31 is reduced, thereby greatly reducing the construction cost and improving the construction efficiency.

[0050] refer to Figure 2 , Figure 3As shown, in some embodiments, a plurality of first bolt through holes 232 are arranged on the bottom plate 23 of the slope protection frame 20. The first bolts 28 corresponding to the first bolt through holes 232 are pre-buried on the bottom wall 11 of the trench 10 of the excavated river channel. When the slope protection frame 20 is installed in the trench 10, the first bolt through holes 232 on the bottom plate 23 are sleeved outside the first bolts 28, and the fastening nuts 29 are screwed into the upper part of the first bolts 28, and the fastening nuts 29 are screwed to press the bottom plate 23, thereby firmly connecting the bottom plate 23 to the trench bottom wall 11 of the trench 10; it can be understood that the first bolt through holes 232 can be step holes so that the fastening nuts 29 are located below the top surface of the bottom plate 23, so as to facilitate the subsequent installation of the planting foundation 31 in the slope protection frame 20. This exemplary embodiment realizes the connection and installation of the slope protection frame 20 in the trench 10.

[0051] refer to Figure 1 , Figure 2 As shown, in some embodiments, a plurality of second bolt holes 211 are arranged on the side panels 21 of the slope protection frames 20. By passing a bolt assembly through the second bolt holes 211 on the adjacent side panels 21 of two slope protection frames 20, convenient connection between two adjacent slope protection frames 20 within a construction section of a preset length can be achieved.

[0052] refer to Figure 1 As shown, in some embodiments, a drainage groove 212 is recessed on the side of the side panel 21 away from the inner cavity of the slope protection frame 20. The drainage groove 212 extends downward in a direction toward the river channel and passes through the front and rear ends of the side panel 21. The inclination angle of the drainage groove 212 can be set to about 3°, which is convenient for guiding the seepage water in the earthwork on the rear side of the slope protection frame 20 into the river channel.

[0053] refer to Figure 3 As shown, in some embodiments, a plurality of diagonal bracing members 25 are arranged between the end surface of the base plate 311 facing away from the river channel and the bottom panel 23, that is, one end of the diagonal bracing member 25 is crimped onto the top surface of the bottom panel 23, and the other end is against the rear end surface of the base plate 311; the plurality of diagonal bracing members 25 can be arranged in multiple rows and columns; through the provision of the diagonal bracing members 25, a more stable support is provided for the vegetation base 31 and the vegetation 32 thereon, that is, the vegetation slope protection 30.

[0054] refer to Figure 7 As shown, in some embodiments, a plurality of weight-reducing grooves 3111 are recessed on the end surface of the base plate 311 facing away from the river channel, and a plurality of reinforcing ribs 3112 are provided in each weight-reducing groove 3111; by providing the weight-reducing grooves 3111, the overall weight of the planting base 31 is reduced, thereby facilitating the transportation and installation of the planting base 31; and by providing the reinforcing ribs 3112, the structural strength of the base plate 311 itself is enhanced.

[0055] refer to Figure 2 , Figure 5As shown, in some embodiments, the back frame plate 24 includes two side frames 241 arranged opposite to each other, a top frame 242 connected between the upper parts of the two side frames 241, and a bottom frame 243 connected between the lower parts of the two side frames 241. The two side frames 241 are respectively connected to the two side panels 21; thus, the back frame plate 24 is an overall square frame structure. The back frame plate 24 also includes a plurality of reinforcing frames 244, which are connected between the top frame 242 and the bottom frame 243 or between the two side frames 241. The reinforcing frames 244 can be arranged vertically, horizontally or obliquely, so that the back frame plate 24 has a plurality of hollow opening structures and ensures the structural strength of the back frame plate 24.

[0060] For foundation treatment, determine whether foundation treatment is needed based on the geological conditions around the river channel and the results of simulation analysis; if the burial depth can meet the anti-scouring requirements, no special treatment is required; if the river section contains soft foundation, fine-grained soil and sand layers and other unfavorable geological conditions greater than the burial depth, all of them should be dug out and replaced with stone blocks; for the foundation of the backfill behind the embankment, it is necessary to remove the debris and backfill soil on the surface of the natural foundation, clear the waste thickness of 0.2m, and press the surface of the foundation. At the same time, according to the requirements of the "Design Code for Embankment Engineering", reserve the settlement of the earth embankment in advance before construction;
