Description

Technical Field

[0001] The utility model belongs to the technical field of bank protection structures, and in particular relates to a combined splicing type ecological bank protection structure. Background Art

[0002] The statements herein merely provide background art related to the present invention and do not necessarily constitute prior art.

[0003] At present, in the field of water conservancy engineering, laying concrete structures, stones or planting vegetation are often used as river bank protection measures to enhance the anti-scouring ability of the bank slope. In the prior art, for example, Chinese utility model patent CN220394415U discloses an ecological bank protection structure, which supports the bank protection by setting stones; Chinese utility model patent CN212426956U discloses an ecological bank protection structure, which buffers the impact of river water by planting vegetation layers. The inventor found that the stone bank protection method has strong anti-scouring performance and low construction cost, but the structure is susceptible to erosion and damage and requires frequent maintenance; although the vegetation bank protection has good ecological benefits, it requires a long growth cycle to form a stable bank protection structure, and the construction cycle is relatively long; in addition, when the bank protection is composed entirely of planted vegetation, the vegetation on the bank slope will cause a high hydraulic roughness, affecting the flood discharge capacity of the river channel. During the flood season, the resistance formed by the bank slope vegetation is prone to uproot the plants, causing local instability of the bank slope and local collapse of the bank slope, causing the problem of large-scale death of vegetation.

[0026] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0028] In a typical implementation of the present invention, Figure 1-3As shown, a combined splicing ecological bank protection structure is provided, including a square grid 1, in which bank protection stones 2 and bank protection vegetation 3 are staggered, and multiple square grids 1 are laid on the slope surface of the bank and connected by a connecting structure. The surface of the square grid 1 is covered with a steel guard net 4, and the square grid 1 is inserted into the inside of the bank through a consolidation pile 5.

[0029] In this embodiment, bolt holes 7 are provided on each outer side surface of the square grid 1, and connecting bolts 6 are used as connecting structures. Adjacent square grids 1 are connected by connecting bolts 6, so that multiple square grids 1 form an integral structure on the revetment. Two vertical grid inner plates are provided in the square grid 1, and the two grid inner plates divide the square grid into four grid slots. The revetment stones 2 and revetment vegetation 3 are diagonally arranged in the square grid, and the grid slots where the revetment vegetation is located are planted by filling soil.

[0030] Furthermore, a pile body hole 8 is provided at the center position of the square grid 1, and the pile body hole 8 is located at the intersection of two grid inner plates. The center position of the bottom of the square grid 1 is fixedly connected to the hollow consolidation pile 5, and the pile body hole 8 is communicated with the hollow consolidation pile 5. A slurry outlet hole 11 is provided below the side wall of the consolidation pile 5. The consolidation pile 5 is buried in the slope and then grouting consolidation is performed.

[0031] In this embodiment, the mesh openings of the steel mesh 4 are of different sizes. The mesh openings of the steel mesh covering the bank protection stones 2 are smaller than the mesh openings of the steel mesh covering the bank protection vegetation 3. The small-mesh protection net 10 covers the bank protection stones 2, and the large-mesh protection net 9 covers the bank protection vegetation 3. The small-mesh protection net 10 is set to prevent the bank protection stones 2 from being washed away. At the same time, when the bank protection vegetation 3 is washed away on a large scale, the large-mesh protection net 9 does not affect the growth of the bank protection vegetation 3.

[0032] In this embodiment, after a plurality of square grids 1 are laid on the slope surface of the bank, the adjacent square grids 1 are aligned and laid side by side on the slope surface of the bank. The number of laying rows is determined according to the slope length of the bank until the slope surface is fully covered. The bank protection stones 2 and bank protection vegetation 3 are distributed at intervals in the horizontal and vertical directions of the bank.

[0033] In this embodiment, the square grid 1 is a steel-plastic composite structure, and the consolidation piles 5 are perforated steel pipes. The consolidation piles 5 are inserted into the pile holes 8 of the square grid 1 and buried inside the slope, and the square grid 1 and the consolidation piles 5 are fixed to the slope by pouring concrete on the consolidation piles 5.

[0034] The construction method of the combined splicing ecological bank protection structure provided by the utility model is as follows:

[0035] Step A, firstly, trim the bank slope surface according to the design requirements, lay square grids 1 according to the size of the slope surface, and connect adjacent square grids 1 with connecting bolts 6 through bolt holes 7;

[0036] Step B, drilling the soil below the pile hole 8 of the square grid 1, inserting the consolidation pile 5, grouting the consolidation pile 5, and consolidating the slurry through the slurry outlet hole 11 with the slope soil to fix the square grid 1;

[0037] Step C, filling the square grid 1 with revetment stones 2 and revetment vegetation 3. In the early stage, the revetment stones 2 are used for protection, and in the later stage, the revetment vegetation 3 grows up to play a protective role together. The revetment vegetation 3 can further consolidate the soil of the bank slope after it grows up.

[0038] Step D, covering the surface of the revetment stones 2 with a layer of small-mesh protection net 10 to prevent the revetment stones 2 from being washed away, and covering the surface of the revetment vegetation 3 with a layer of large-mesh protection net 9 to prevent the revetment vegetation 3 from being washed away on a large scale without affecting the growth of the revetment vegetation 3.

[0039] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
