The stability of the revetment wall made of stone blocks is poor, which is easy to collapse and has a safety hazard, and the revetment wall made of cast-in-place reinforced concrete has a long construction period, high cost and great difficulty; 2. The impact force of the river water is large, and the turf is easy to be washed away by the river water, which needs to be maintained frequently. SUMMARY

[0004] In order to solve the above technical problems, the present application adopts the following technical scheme:

[0005] A construction method of gabion revetment structure, characterized in that it comprises the following steps:

[0006] (a) leveling the construction site and demarcating the construction area;

[0007] (b) arranging the first layer of revetment structure:

[0008] I. arranging the first row of revetment units:

[0009] ① placing the bottom plate along the construction reference line in the construction area, installing the ladder planting box on the bottom plate through the support rod, and planting plants in the planting groove of the ladder planting box;

[0010] ② inserting the horizontal baffle between the adjacent two L-shaped boards to form a protective frame surrounded by the four L-shaped boards;

[0011] ③ on the previous row of bottom plates, inserting two L-shaped boards on one side on the first bottom plate and two L-shaped boards on the other side on the second bottom plate, so that the first protective frame is installed between the first bottom plate and the second bottom plate;

[0012] ④ inserting the rotating shaft of the wave baffle into the connecting concave hole of the L-shaped board of the first protective frame, so that the wave baffle is temporarily limited on the side of the first protective frame;

[0013] ⑤ Insert the second protective frame into the second and third base plates, then slide the wave baffle so that the other end of the rotating shaft is inserted into the connecting recess of the L-shaped protective plate of the second protective frame, so that the wave baffle is limited between the first and second protective frames, and the stepped planting box on the second base plate is located between the first and second protective frames.

[0014] ⑥ Insert a wave baffle on the other side of the second protective frame, then install the third protective frame on the third and fourth bottom plates, and then slide the wave baffle so that the wave baffle is limited between the second and third protective frames;

[0015] ⑦ Install the wave-breaking plate and the protective frame step by step, following the method of first inserting the wave-breaking plate, then installing the protective frame, and finally sliding the wave-breaking plate to limit its movement;

[0016] ⑧ Insert the gabion mesh box into the protective frame and fill the gabion mesh box with stones;

[0017] ⑨ Install a cover plate on top of the protective frame to seal the frame and complete the arrangement of the first row of revetment units;

[0018] II. Arrange the second row of revetment units:

[0019] ① Install a protective frame between two adjacent base plates on the back row of base plates;

[0020] ②Insert the gabion mesh box into the protective frame and fill the gabion mesh box with stones;

[0021] ③ Install cover plates to seal the protective frame, completing the arrangement of the second row of revetment units;

[0022] (c) Arrange the second layer of revetment structure:

[0023] ① Install the first protective frame on the first cover plate of the two rows of revetment units in order from left to right, so that the front and rear cover plates are connected and support the upper protective frame;

[0024] ② Insert a wave-breaking plate on one side of the first protective frame, then install the second protective frame on the second cover plate of the two rows of revetment units, and then slide the wave-breaking plate so that the wave-breaking plate is limited between the first protective frame and the second protective frame;

[0025] ③ Install the wave-breaking plate and the protective frame step by step, following the method of first inserting the wave-breaking plate, then installing the protective frame, and then sliding the wave-breaking plate to limit the position;

[0026] ④ Place a second-layer stepped planting box between two adjacent protective frames, and install a support rod between the upper and lower stepped planting boxes. The stepped planting box is supported by two adjacent cover plates and the support rod.

[0027] ⑤ Plant plants in the planting troughs of the tiered planting box;

[0028] ⑥ Insert the gabion mesh into the second layer of the protective frame and fill the gabion mesh with stones;

[0029] ⑦ Install the cover plate to seal the second layer of the protective frame, completing the layout of the second layer of the revetment structure.

[0030] Furthermore, in step (b), the bottom plate is provided with a limiting recess corresponding to the support rod, the bottom surface of the stepped planting box is provided with a first recess corresponding to the support rod, and the bottom surface of the planting trough of the stepped planting box is provided with a second recess corresponding to the support rod. The specific method for installing the stepped planting box is as follows: first, insert the support rod into the limiting recess on the bottom plate to limit the support rod on the bottom plate, and then fit the first recess on the bottom surface of the stepped planting box over the upper end of the support rod to limit the support rod between the bottom plate and the stepped planting box, and the support rod provides support to the stepped planting box.

[0031] Furthermore, in step (b), both sides of the horizontal baffle are provided with mounting protrusions, and the side of the L-shaped guard plate is provided with slots corresponding to the mounting protrusions; the bottom of the L-shaped guard plate is provided with an inner support plate for supporting the gabion cage, and the bottom of the inner support plate is provided with a support column, and the bottom plate is symmetrically distributed with limiting through holes corresponding to the support column; the wave baffle includes a plate body and a rotating shaft, the plate body is set on the rotating shaft, and the L-shaped guard plate is longitudinally distributed with connecting recesses corresponding to the rotating shaft.

[0032] Furthermore, in step (b), the top of the L-shaped guard plate is provided with positioning holes, the bottom surface of the cover plate is symmetrically distributed with inserts corresponding to the positioning holes, and the cover plate is symmetrically distributed with through holes corresponding to the support columns.

[0033] Furthermore, during the filling process, the stone size around the perimeter of the gabion is larger than that in the central area to prevent the stones from shifting within the gabion and constantly compressing it, thus damaging its structure. The filling height of the stones is 5-10cm lower than the height of the gabion, ensuring sufficient filling weight and increasing the density of the gabion.

[0034] Furthermore, in step (b), after the two rows of revetment units are arranged, U-shaped ground nails are passed through the limiting through holes on the two outermost bottom plates and inserted into the soil of the foundation to fix the bottom plates in place. The bottom plates on the same row are held together by the protective frame to ensure alignment without misalignment. Fixing the two outermost bottom plates ensures that the two rows of bottom plates remain parallel and aligned to each other, and the distance between the two rows of bottom plates is limited to prevent the two bottom plates from misaligning, which would cause the two protective frames to misalign and thus affect the installation of the upper protective frame and the connection of the upper and lower stepped planting boxes. There is no need to fix other bottom plates separately, resulting in low construction intensity and high construction efficiency.

[0035] Furthermore, in step (c), after the two-layer revetment structure is arranged, a layer of stones is laid on the cover plate with a height of 10-15cm. The stones press down on the cover plate to prevent it from detaching from the protective frame, which improves the installation reliability of the cover plate and prevents it from being blown away by strong winds or detached by waves. The stones are sourced locally, which is economical and convenient.

[0036] The present invention, by adopting the above-described technical solution, has the following beneficial effects:

[0037] 1. Compared with existing reinforced concrete revetment walls, the gabion revetment structure of the present invention involves fewer equipment, has lower material and equipment costs, simpler processes, is more convenient to construct, saves time and labor, is gradually and orderly, is easy to control and adjust, and ensures construction quality.

[0038] 2. The upper protective frame simultaneously restricts the displacement between the two lower protective frames, and the two lower protective frames prevent the upper protective frame from falling apart, forming a mutually restraining relationship between the upper and lower parts, which improves the stability of the entire bank protection structure, strengthens its scour resistance, and makes it less likely to be washed away by river water or shift its position, resulting in a good bank protection effect.

[0039] 3. Each gabion box is independent and does not contact each other, avoiding damage caused by the compression of stones between closely arranged gabion boxes, thus extending the service life of the gabion boxes. The protective frame provides external protection for the gabion boxes, surrounding them inside. Even if the gabion box is damaged, stones are not likely to escape from the protective frame, allowing it to continue to play its role in bank protection. The horizontal baffles can prevent the steel wires of the gabion boxes from deforming outward and breaking, extending the service life of the gabion boxes and making them durable.

[0040] 4. The tiered planting boxes containing plants are located between two protective frames, preventing them from being squeezed by the stones inside the gabion cages. This protects the tiered planting boxes from direct impact from the river water, thus preventing structural damage. It also forms a green landscape line that blends well with the surrounding natural environment without appearing abrupt, enhancing the aesthetics. The arrangement of the upper and lower tiered planting boxes indirectly increases the density of the entire revetment structure, making it less likely to be washed away by the river.

[0041] 5. The wave deflector is designed to withstand the impact of river water. When the river water hits the wave deflector, the deflector rotates, which greatly reduces the impact force. The river water spreads outward and falls into the tiered planting boxes, where it is utilized by the plants. This has certain ecological benefits and prevents the plants in the tiered planting boxes from being washed away by the river water due to excessive direct impact. Attached Figure Description

Detailed Implementation

[0054] like Figures 1 to 10 The diagram illustrates a construction method for a gabion revetment structure according to the present invention, comprising the following steps:

[0055] (a) Leveling the construction site and delineating the construction area: Clean up the garbage at the construction site, level the construction surface, and delineate the construction area according to the construction drawings.

[0056] (b) Arrange the first layer of revetment structure:

[0057] I. Arrange the first row of revetment units:

[0058] ① The base plate 1 is provided with a limiting recess 3 corresponding to the support rod 2, the bottom surface of the stepped planting box 4 is provided with a first recess 5 corresponding to the support rod 2, and the bottom surface of the planting trough 6 of the stepped planting box 4 is provided with a second recess 7 corresponding to the support rod 2.

[0059] Two rows of base plates 1 are placed within the construction area along the construction reference line. Base plates 1 serve as the load-bearing foundation and have high flatness, eliminating the problem of unevenness on the construction surface. Then, support rods 2 are inserted into the limiting recesses 3 on the base plates 1, limiting the support rods 2 to their position on the base plates 1. Next, the first recess 5 on the bottom surface of the stepped planting box 4 is fitted over the upper end of the support rods 2, limiting the support rods 2 between the base plates 1 and the stepped planting box 4. The support rods 2 provide support to the stepped planting box 4, and together with the base plates 1, they provide support to the stepped planting box 4. This front and rear support prevents the stepped planting box 4 from tipping over freely, ensuring the installation stability of the stepped planting box 4 and achieving rapid installation and positioning of the stepped planting box 4 on the base plates 1. The operation is simple.

[0060] Next, plant the plants in the planting trough 6 of the stepped planting box 4;

[0061] ②The horizontal baffle 8 has mounting protrusions 9 on both sides, and the L-shaped guard plate 10 has slots 11 on the side corresponding to the mounting protrusions 9.

[0062] Insert the mounting protrusion 9 of the horizontal baffle 8 into the slot 11 of the L-shaped guard plate 10, so that the horizontal baffle 8 is limited between the two L-shaped guard plates 10, and they are connected in pairs to form a protective frame with the four L-shaped guard plates 10. The connection is simple, the operation is easy, and the construction efficiency is high.

[0063] ③ The bottom of the L-shaped guard plate 10 is provided with an inner support plate 13 for supporting the gabion box 12. The bottom of the inner support plate 13 is provided with a support column 14. The bottom plate 1 has symmetrically distributed limiting through holes 15 corresponding to the support column 14.

[0064] On the first row of base plates 1, insert the support column 14 at the bottom of the L-shaped guard plate 10 into the limiting through hole 15 on the base plate 1, so that the two L-shaped guard plates 10 on one side of the protective frame are inserted on the first base plate 1 and the two L-shaped guard plates 10 on the other side are inserted on the second base plate 1, so that the first protective frame is installed between the first base plate 1 and the second base plate 1.

[0065] ④ The wave deflector 16 includes a plate body 17 and a rotating shaft 18. The plate body 17 is mounted on the rotating shaft 18. The L-shaped guard plate 10 has longitudinally distributed connecting recesses 19 corresponding to the rotating shaft 18.

[0066] Insert the rotating shaft 18 of the wave deflector 16 into the connecting recess 19 on the side of the first protective frame, so that the wave deflector 16 is temporarily limited to the side of the first protective frame.

[0067] ⑤ Install the second protective frame between the second base plate 1 and the third base plate 1, and then slide the wave baffle 16 laterally so that the other end of the rotating shaft 18 is inserted into the connecting recess 19 on the side of the second protective frame, so that the wave baffle 16 is limited between the first protective frame and the second protective frame, and the stepped planting box 4 on the second base plate 1 is located between the first protective frame and the second protective frame.

[0068] ⑥ Insert a wave baffle 16 on the other side of the second protective frame, then install the third protective frame on the third bottom plate 1 and the fourth bottom plate 1, and then slide the wave baffle 16 laterally so that the wave baffle 16 is limited between the second and third protective frames.

[0069] ⑦ The wave-blocking plate 16 and the protective frame are installed step by step in an orderly manner, which is easy to control and adjust, and ensures the construction quality.

[0070] ⑧ Insert the gabion box 12 into the protective frame and fill the gabion box 12 with stones. During the filling process, the stone size of the surrounding area of ​​the gabion box 12 is larger than that of the stone size of the middle area to prevent the stones from moving around in the gabion box 12 and continuously squeezing the gabion box 12, thereby damaging the structure of the gabion box 12. The filling height of the stones is 5-10cm lower than the height of the gabion box 12 to ensure sufficient filling weight and increase the density of the gabion box 12.

[0071] Gabion cage 12 is a square cage made of corrosion-resistant steel wire. The corrosion-resistant steel wire is at least one of galvanized steel wire and galvanized aluminum steel wire, which has good corrosion resistance, long service life, and is stable and sturdy.

[0072] ⑨ The top of the L-shaped guard plate 10 is provided with a positioning hole 20, and the bottom surface of the cover plate 21 is symmetrically distributed with inserts 22 corresponding to the positioning hole 20. The cover plate 21 is symmetrically distributed with through holes 23 corresponding to the support column 14.

[0073] Insert the pins 22 of the cover plate 21 into the positioning holes 20 of the four L-shaped guard plates 10, so that the cover plate 21 is limited to the top of the protective frame, and the protective frame is sealed, thus completing the arrangement of the first row of revetment units.

[0074] The cover plate 21 prevents stones from moving upwards and falling out of the gabion box 12, and at the same time limits the spacing of the four L-shaped guard plates 10. The protective frame will not fall apart, effectively surrounding the gabion box 12. The entire row of revetment units will not fall apart, and the structure is stable and reliable.

[0075] II. Arrange the second row of revetment units:

[0076] ① Install a protective frame between two adjacent base plates 1 on the back row of base plates 1;

[0077] ②Insert the gabion box 12 into the protective frame and fill the gabion box 12 with stones;

[0078] ③ Install cover plate 21 to seal the protective frame and complete the arrangement of the second row of revetment units;

[0079] ④ Pass the U-shaped ground nails 24 through the limiting through holes 15 on the two outermost bottom plates 1 and insert them into the soil of the foundation to fix the bottom plates 1 in place. The bottom plates 1 on the same row are held together by the protective frame and aligned without being misaligned. Fix the two outermost bottom plates 1 so that the two rows of bottom plates 1 in front and behind remain parallel and aligned to each other, and the distance between the two rows of bottom plates 1 in front and behind is limited to avoid the two bottom plates 1 in front and behind being misaligned, which would cause the two protective frames in front and behind to be misaligned, thus affecting the subsequent installation of the upper protective frame and the docking of the two upper and lower stepped planting boxes 4. There is no need to fix other bottom plates 1 separately, which has low construction intensity and high efficiency.

[0080] Wave-breaking plates 16 are installed on the front row of revetment units to resist the impact of river water. When the river water hits the wave-breaking plates 16, the wave-breaking plates 16 rotate, and the impact force is greatly reduced. The river water spreads outward and falls into the stepped planting boxes 4, where it is utilized by the plants. This has certain ecological benefits and prevents the plants in the stepped planting boxes 4 from being washed away by the river water due to excessive direct impact.

[0081] Each gabion cage 12 is independent and does not contact each other, preventing damage caused by the squeezing of stones between closely arranged gabion cages 12, thus extending the service life of the gabion cages 12. The protective frame provides external protection for the gabion cages 12, surrounding them. Even if a gabion cage 12 is damaged, stones are unlikely to escape from the protective frame, allowing it to continue to function as a bank protection structure. The horizontal baffle 8 prevents the steel wires of the gabion cage 12 from deforming outwards and breaking, further extending the service life of the gabion cage 12, making it durable. The tiered planting box 4, containing plants, is located between the two protective frames and is not squeezed by the stones inside the gabion cages 12. On the one hand, it protects the tiered planting box 4 from direct impact from the river water, preventing structural damage. On the other hand, it forms a green landscape line that blends well with the surrounding natural environment, without appearing abrupt, thus improving aesthetics.

[0082] (c) Arrange the second layer of revetment structure:

[0083] ① Following the order from left to right, install the first protective frame on the first cover plate 21 of the two rows of revetment units, insert the support column 14 at the bottom of the protective frame into the through hole 23 of the cover plate 21, so that the two cover plates 21 are connected and support the upper protective frame, the lower cover plate 21 cannot slide freely, thereby limiting the upper protective frame from falling apart and improving the assembly reliability.

[0084] ② Insert a wave-blocking plate 16 on one side of the first protective frame, then install the second protective frame on the second cover plate 21 of the two rows of revetment units, and then slide the wave-blocking plate 16 laterally so that the wave-blocking plate 16 is limited between the first protective frame and the second protective frame.

[0085] ③ Install the wave-blocking plate 16 and the protective frame step by step in the manner of first inserting the wave-blocking plate 16, then installing the protective frame, and then sliding the wave-blocking plate 16 laterally to limit its position;

[0086] ④ Place the second-layer stepped planting box 4 between two adjacent protective frames, insert the support rod 2 into the second concave hole 7 of the first-layer stepped planting box 4, so that the support rod 2 is limited on the first-layer stepped planting box 4, and then put the first concave hole 5 on the bottom surface of the second-layer stepped planting box 4 over the upper end of the support rod 2, so that the support rod 2 is limited between the upper and lower stepped planting boxes 4. The two adjacent cover plates 21 of the first layer and the support rod 2 together provide support for the second-layer stepped planting box 4, ensuring the installation stability of the stepped planting box 4 and preventing it from tipping over freely. The arrangement of the upper and lower stepped planting boxes 4 indirectly increases the density of the entire revetment structure, making it less likely to be washed away by river water.

[0087] ⑤ Plant plants in the planting trough 6 of the second-level stepped planting box 4;

[0088] ⑥ Insert the gabion box 12 into the second layer of the protective frame, and fill the gabion box 12 with stones. During the filling process, the stone size of the surrounding area of ​​the gabion box 12 is larger than that of the stone size of the middle area, and the filling height of the stones is 5-10cm lower than the height of the gabion box 12.

[0089] ⑦ Install cover plate 21 to seal the second layer of protective frame, completing the arrangement of the second layer of revetment structure. Cover plate 21 can restrict the second layer of protective frame from spreading out, improving the assembly reliability of the second layer of protective frame. The second layer of protective frame restricts the displacement between the two cover plates 21 below. The two rows of revetment units in the first layer will not move relative to each other, forming a mutual restraint relationship between the upper and lower parts, connecting them into one, improving the stability of the entire revetment structure, with strong scour resistance, not easily washed away by river water or displaced, and good revetment effect.

[0090] ⑧ Lay a layer of stones on the cover plate 21, with a laying height of 10-15cm. The stones press down on the cover plate 21 to prevent it from detaching from the protective frame, thus improving the installation reliability of the cover plate 21 and preventing it from being blown away by strong winds or hit by waves. The stones are sourced locally, making it economical and convenient.

[0091] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.
