[0002] A revetment is a facility built at the junction of the edge of a water body and land. Its main purpose is to stabilize the revetment through engineering measures to prevent it from being damaged by various natural and human factors. In garden engineering, the revetment is the part that should be focused on in the hydrophilic landscape. Its design not only affects the visual effect of the landscape, but is also directly related to the safety of the water body and the shore.

[0003] Revetments are an important part of water landscapes, but revetments in highly saline-alkali waters are prone to damage such as corrosion and freeze-thaw, which directly affect the landscape effect. Revetments are usually divided into stone revetments, aquatic plant revetments, etc. Pebbles are placed directly on the revetments and aquatic plants are planted. Due to the special conditions of saline-alkali land, the vegetation is severely damaged and the landscape effect is poor.

[0004] Therefore, it is necessary to provide a new revetment structure for strongly saline-alkali waters to solve the above technical problems. Utility Model Content

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0026] See also Figures 1 to 4 The embodiment of the present invention provides a revetment structure for strongly saline-alkali waters, which comprises a stainless steel gabion 1 and a bentonite blanket 2.

[0027] In the embodiments of the present invention, please refer to Figures 1 to 4 The bottom of the stainless steel gabion 1 is paved with a bentonite blanket 2. Specifically, a compacted soil layer 4 is laid at the revetment of the water area, and a leveled medium sand layer 5 is laid on the soil layer 4. The bentonite blanket 2 is laid on the medium sand layer 5, and a compacted covering soil layer 6 is laid on the bentonite blanket 2. It should be noted that the bottom of the stainless steel gabion 1 is pre-buried in a groove reserved in the medium sand layer 5, and the stainless steel gabion 1 includes a stainless steel frame 11 and crushed stones 12, and the crushed stones 12 are filled in the stainless steel frame 11;

[0028] A planting soil layer 7 is laid along the shore of the precast concrete strip 3 facing away from the stainless steel gabion 1, and a planting soil layer 7 is laid on the side of the precast concrete strip 3 away from the water. Vegetation 8 for soil consolidation is planted on the planting soil layer 7. The wall thickness of the precast concrete strip 3 is 60-90 cm, and the precast concrete strip 3 is stacked on the medium sand layer 5.

[0029] It should be noted that: the revetment structure of the strong saline-alkali water area mainly adopts stainless steel gabions 1 connected with bentonite blanket 2. The stainless steel gabions 1 not only fix the bentonite blanket 2, but also serve as part of the landscape stone revetment, and play a good role in preventing the return of salt and alkali in the water area, which makes the shore plants 8 unable to survive. At the same time, precast concrete strips 3 are built on the back of the stainless steel gabions 1 away from the water area. On the one hand, they play a role in counteracting the stainless steel gabions 1, making the stainless steel gabions 1 more stable. On the other hand, the precast concrete strips 3 effectively block the influence of salt and alkali in the water area on the plants 8 caused by the infiltration of salt and alkali in the stainless steel gabions 1.

[0030] The structure of compacting the plain soil layer 4, leveling the medium sand layer 5, laying the bentonite blanket 2, and then compacting the cover soil layer 6 can effectively prevent the rise of salt and alkali, which will cause damage to the revetment stones and vegetation, and has a good anti-salinity effect.

[0031] In order to facilitate the placement of the precast concrete strips 3, the precast concrete strips 3 can be placed in a frame welded by stainless steel, so that the periphery of the precast concrete strips 3 is also provided with a stainless steel frame. When the stainless steel frame with the precast concrete strips 3 is placed, a tunnel is pre-dug on the base soil, and the precast concrete strips 3 with the stainless steel welded frame are placed in the tunnel, so that part of the wall of the precast concrete strips 3 is pre-buried underground, thereby further enhancing the stability of the precast concrete strips 3.

[0032] In addition, the thickness of the precast concrete strip 3 is 200-300 mm.

[0033] It is worth noting that bentonite blanket 2 is a bentonite waterproof blanket, which is made of highly expansive sodium-based bentonite filled between a special composite geotextile and a non-woven fabric. It is a bentonite anti-seepage mat made by needle punching. It can form many small fiber spaces, so that the bentonite particles cannot flow in one direction. When it comes into contact with water, it forms a uniform and high-density gel-like waterproof layer inside the mat, thereby effectively preventing water leakage.

[0034] Among them, the stainless steel frame 11 is welded from stainless steel material with a height and width of 400*400mm, and the diameter of the stainless steel is φ8mm. An intermediate grid is welded in the middle of the stainless steel frame 11, and the diameter of the intermediate grid is φ6mm. The bottom of the stainless steel frame 11 is fixedly connected to the upper edge of one side of the bentonite blanket 2, so that the bentonite blanket 2 can be fixed.

[0035] In the embodiments of the present invention, please refer to Figures 1 to 4 A floating component 9 is provided on the stainless steel gabion 1, and the floating component 9 includes a welding plate 91, and the welding plate 91 is fixedly welded to the upper surface of the stainless steel frame 11, and an elastic corrugated expansion plate 92 is fixedly embedded on the welding plate 91, and a buoyancy box 93 is fixedly installed on the elastic corrugated expansion plate 92, and the four corners of the lower surface of the buoyancy box 93 are tied with limiting ropes 94, and the limiting ropes 94 are fixedly connected to the welding plate 91 respectively.

[0036] It should be noted that when the water tide rises at the revetment, the buoyancy box 93 on the stainless steel gabion 1 can float along the rising water tide and stretch the elastic pleated expansion plate 92, thereby effectively blocking the rising water and reducing the phenomenon of strong saline-alkali water overflowing the stainless steel gabion 1, and the limiting rope 94 can limit the buoyancy box 93. In addition, in order to improve the service life of the floating assembly 9, each component of the floating assembly 9 is coated with a coating that is resistant to strong salt and alkali (the specific coating is not limited here and can be selected according to needs).

[0037] The working principle of the revetment structure in strongly saline-alkali waters provided by the utility model is as follows:

[0038] The revetment structure of the strong saline-alkali water area mainly adopts stainless steel gabions 1 connected with bentonite blanket 2. The stainless steel gabions 1 not only fix the bentonite blanket 2, but also serve as part of the landscape stone revetment, and play a good role in preventing the return of salt and alkali in the water area, which makes the shore plants 8 unable to survive. At the same time, precast concrete strips 3 are built on the back of the stainless steel gabions 1 away from the water area. On the one hand, it plays a role in counteracting the stainless steel gabions 1, making the stainless steel gabions 1 more stable. On the other hand, the precast concrete strips 3 effectively block the influence of salt and alkali in the water area on the plants 8 caused by the infiltration of salt and alkali in the stainless steel gabions 1.

[0039] When the tide rises at the revetment, the buoyancy box 93 on the stainless steel gabion 1 can float along the rising tide and stretch the elastic pleated expansion plate 92, thereby effectively blocking the rising water and reducing the phenomenon of strong saline-alkali water overflowing the stainless steel gabion 1. The limiting rope 94 can limit the buoyancy box 93. In addition, in order to increase the service life of the floating assembly 9, each component of the floating assembly 9 is coated with a strong salt and alkali resistance coating;

[0040] The structure of compacting the plain soil layer 4, leveling the medium sand layer 5, laying the bentonite blanket 2, and then compacting the cover soil layer 6 can effectively prevent the rise of salt and alkali, which will cause damage to the revetment stones and vegetation, and has a good anti-salinity effect.

[0041] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0042] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
