Abstract
Description
Technical Field
[0001] The utility model relates to an ecological revetment, in particular to a biologically enhanced ecological revetment. Background Art
[0002] As an amphibious transition zone, the riverbank has a complex and fragile ecological environment, which is easily affected by water erosion and human activities. Traditional bank protection technology often uses hard materials, such as ecological bricks, gabion grids, etc., to prevent water from eroding the bank slope. However, this method will cause damage to the original riverbank ecosystem. At the same time, this type of hard ecological bank protection is not well integrated during the protection process, and cracks and gaps are prone to occur, resulting in the problem of water erosion. In addition, plants need to be planted every year, which has high maintenance costs and cannot provide a natural habitat for underwater organisms. Utility Model Content

The revetment units include a hexagonal double-layer steel frame with an ecological woven mesh placed in the middle. The double-layer steel frame is erected on the river bank through multiple groups of anchor piles. The anchor piles include cement piles pre-buried underground in the river bank and cable buckle assemblies for fixing the double-layer steel frame to the top of the cement piles.
[0005] The steel frame is a structure formed by welding steel bars, with a hexagonal outer surface and a circular inner surface. Each vertex of the hexagon and the inner circle has a reinforcing rib.
[0006] Wherein, a longitudinal steel bar column is pre-embedded inside the cement pile, the upper end of the longitudinal steel bar column protrudes from the upper surface of the cement pile and is fixedly connected to the cable buckle assembly.
[0007] The cable buckle assembly includes a fixing plate horizontally welded to the upper end of the longitudinal steel bar column and a U-shaped lock installed on the fixing plate; the fixing plate is provided with two groups of through holes for passing the U-shaped lock.
[0008] Wherein, both ends of the U-shaped lock are threaded structures, and nuts are used to fix the U-shaped lock, whose two ends pass through the through holes on the fixing plate, to the fixing plate.
[0009] When the U-shaped lock is fixedly connected to the fixing plate, the edge or vertex of the double-layer steel bar skeleton is located in the inner area of the U-shaped lock.
[0010] The cross section of the cement pile is an I-shaped structure.
[0011] Wherein, the multiple groups of bank protection units are arranged and spliced in a hexagonal close-paving manner.
[0012] Beneficial effects: The utility model has the following advantages: the ecological revetment is composed of multiple groups of revetment units based on ecological woven nets, and the ecological woven nets are placed in a double-layer steel frame, which not only enhances the stability of the structure, but also ensures sufficient elasticity to cope with the impact of waves and the like, effectively improving the impact resistance of the river bank; the application of the ecological woven net effectively improves the ecological restoration capacity of the river bank and provides a good habitat for aquatic and terrestrial organisms.

[0017] The technical solution of the utility model is described in detail below in conjunction with the embodiments and drawings.
[0018] like Figure 1 As shown, the ecological revetment described in the utility model is composed of multiple groups of revetment units based on ecological woven nets. In the field of ecological revetment, the net woven from plant branches is usually called "plant revetment net" or "ecological woven net", that is, a mesh structure with certain strength and elasticity is formed by weaving plant branches, such as willow branches with good toughness, easy germination, deep roots and strong waterlogging resistance.
[0019] The revetment unit comprises a hexagonal double-layer steel frame 1, and the ecological woven mesh 2 is placed in the middle of the double-layer steel frame 1, that is, between the upper and lower steel frames 1. Figure 2 The upper or lower steel frame 1 is a structure formed by welding steel bars with a hexagonal outer periphery and a circular inner periphery, and each vertex of the hexagon and the inner circle has a reinforcing rib, thereby improving the strength of the steel frame 1 and better fixing the ecological woven mesh 2.
[0020] like Figure 3As shown, the double-layer steel skeleton 1 is firmly erected on the river bank through multiple groups of anchor piles 3. The anchor piles 3 include cement piles 31 and cable buckle assemblies 32. The cable buckle assemblies 32 are fixed to the top of the cement piles 31 by connecting the longitudinal steel bar columns 33 pre-buried in the cement piles 31. The cement piles 31 are I-shaped in cross section (the I-shaped structure can increase the contact area between the cement piles and the river bank, and at the same time, gravel can be filled on the side of the I-shaped cement piles to further improve stability. The lower part is pre-buried in the river bank, and the upper part is connected to the double-layer steel skeleton 1 through the cable buckle assembly 32. The longitudinal steel bar columns 33 not only provide a solid connection point for the double-layer steel skeleton 1 to ensure the firmness of the entire bank protection structure, but also improve the overall stability and bending and shear resistance of the cement piles 31, and help the cement piles 31 disperse the stress transmitted by the double-layer steel skeleton 1 and the ecological woven net 2, thereby reducing fatigue damage to the cement piles 31.
[0021] like Figure 4 As shown, the upper end of the longitudinal steel bar column 33 protrudes from the upper surface of the cement pile 31, and a fixing plate 321 is horizontally welded to the upper end of the longitudinal steel bar column 33. Two groups of through holes are provided on the fixing plate 321 for passing the U-shaped lock 322. Both ends of the U-shaped lock 322 are threaded structures. After the two ends of the U-shaped lock 322 pass through the through holes on the fixing plate 321, nuts are used to lock the two ends of the U-shaped lock 322 to fix it to the fixing plate 321. At this time, the edge or vertex of the double-layer steel bar skeleton 1 is located in the inner area of the U-shaped lock 322, and the double-layer steel bar skeleton 1 is further fixed to the upper end of the cement pile 31 through the rope buckle assembly 32.
[0022] Working principle: Pre-embed multiple groups of cement piles 31 containing longitudinal steel bars 33 on the river bank, place the ecological woven net 2 in the middle of the double-layer steel skeleton 1, pass the U-shaped lock 322 around the apex of the double-layer steel skeleton 1, and fix it on the fixing plate 321 to fix the double-layer steel skeleton 1 and the cement pile 31. Repeat this step until multiple groups of revetment units are arranged and spliced according to the principle of hexagonal paving to form a continuous and closely connected ecological revetment. This design not only enhances the stability of the revetment structure, but also provides it with sufficient elasticity to adapt to the impact of waves. The application of the ecological woven net 2 effectively improves the ecological restoration capacity of the river bank and provides a good habitat for aquatic and terrestrial organisms.
[0023] In practical applications, the weaving density of the ecological woven net 2 can be adjusted in combination with specific project requirements and environmental conditions, so as to achieve a balance among cost, strength, elasticity, permeability, ecological restoration and aesthetic effects while ensuring the ecological revetment function.
