Description

Technical Field

[0001] This application relates to the technical field of sand-ribbed soft drainage systems, and in particular to a seawall anti-erosion structure with a sand-ribbed cushion layer filter structure and its construction method. Background Technology

[0002] In the field of water-related engineering construction, scour-resistant structures (i.e., sand-ribbed flexible sluice gates) have been widely used in underwater engineering projects such as waterway improvement, sluice gates and dams, dam protection, riprap revetments, and river management. They feature filtration, isolation, scour resistance, integrity, and strong applicability. Their main function is energy dissipation and scour prevention, ensuring that the sediment beneath the sluice gate is protected from water erosion, thereby protecting the structural stability of the main structure.

[0003] When laying sand-ribbed soft rafts, the raft body is usually placed on the hull, multiple sand rib bags are fixedly installed on the raft body, and the raft body is placed on the water surface. There is no connection between adjacent sand-ribbed soft rafts, which results in poor stability of the sand-ribbed soft rafts and reduces the energy dissipation and scour prevention effect. Summary of the Invention

[0004] To improve the energy dissipation and erosion prevention effect, this application provides a seawall erosion prevention structure with a sand rib cushion layer reverse filter structure and its construction method.

[0005] Firstly, this application provides a seawall anti-erosion structure with a sand rib padding filter structure, which adopts the following technical solution: A seawall anti-erosion structure with a sand rib pad filter structure includes multiple rafts and multiple sand rib bags located on the rafts. Adjacent rafts are connected to each other by a connecting component. The connecting component includes several connecting ropes and two connecting pieces. The several connecting ropes pass through the two rafts and are respectively connected to the two connecting pieces, so that the two connecting pieces abut against the rafts for positioning.

[0006] By adopting the above technical solution, the raft body is placed on the hull, multiple sand rib bags are filled with sand and fixedly installed on the raft body, several connecting ropes are fixedly connected to the connecting parts, and several connecting ropes are passed through the stern of the raft body. The hull moves and the raft body is placed in the water and floats on the water surface. The raft body can also support and position the connecting parts.

[0007] After the raft is placed on the hull, the connecting rope on the previous raft is passed through the raft on the hull and fixed to the connector. The connector is positioned against the raft, and the two rafts are positioned against each other. Then, sandbags are fixedly installed on the raft. The hull is then moved to put the raft into the water. This process is repeated to fix multiple rafts together, thereby improving the energy dissipation and anti-erosion effect.

[0008] Meanwhile, since the raft body is made of soft materials such as cloth, it is fixedly connected to multiple connecting ropes through connectors, thereby reducing the risk of damage to the raft body due to different tensions of the connecting ropes. At the same time, the connecting ropes can also adapt to the process of raft body production and placement, further improving the energy dissipation and anti-erosion effect, and also making it easier to lean against the previous raft body during laying, thus improving construction efficiency.

[0009] Optionally, the connector is a plate-shaped structure made of lightweight material, and there are at least two connecting ropes, which pass through the connector and are fixedly tied together for positioning.

[0010] By adopting the above technical solution, the setting of the connector can increase buoyancy, improve the stability of the connector connection, and further improve the energy dissipation and anti-impact effect; at the same time, the two adjacent connecting ropes are tied together and fixed, and the two connecting ropes pass through the connector at different positions, which greatly improves the convenience and stability of fixing the connecting ropes to the connector, further improving the energy dissipation and anti-impact effect and construction efficiency.

[0011] Optionally, the connecting rope is made of a metal material.

[0012] By adopting the above technical solution, it is more convenient and stable to tie and fix the two connecting ropes, which further improves the energy dissipation and anti-erosion effect and construction efficiency.

[0013] Optionally, the sand rib bag includes: The bag body is used to hold sand and is fixedly connected to the outlet body by multiple binding components; Multiple bag openings are spaced apart on the bag body and communicate with the inside of the bag, allowing sand inside the bag to move to the bag opening for support. Sand is filled into the bag body through the multiple bag openings, allowing the sand to move to the bag opening for support, and is fixed by binding with fixing components. The multiple binding components are correspondingly arranged with the multiple bag openings, and the binding components are located on both sides of the bag opening and press against the connection between the bag opening and the bag body for positioning.

[0014] By adopting the above technical solution, sand is filled into the bag at the same time through multiple bag openings, which greatly saves the time spent filling the sand; at the same time, it also shortens the distance between the sand addition point and the inside of the bag, so that the sand can enter the bag more evenly and compactly, thus improving the energy dissipation and anti-erosion effect.

[0015] Meanwhile, the fixing components enable the bag opening to be fixedly connected to the filling equipment during sand filling, and can also be tied and sealed after sand filling, improving construction efficiency. The sand inside the bag opening provides support, and when the bag is tied and fixed to the slab, the tying components press against the bag opening for positioning, thus greatly improving the fixing effect of the bag. Furthermore, when the sand inside the bag decreases, sand can be added to the bag opening, allowing the tying components to continue to position the bag, thereby further improving stability and energy dissipation and erosion prevention effects.

[0016] Optionally, the binding assembly includes; Binding component one and binding component two pass through the bag body and around the bag body for binding and fixing. Binding component one and binding component two are located on both sides of the bag opening and are respectively pressed against the connection between the bag opening and the bag body for positioning.

[0017] By adopting the above technical solution, binding component one and binding component two are located on both sides of the bag opening, and the sand at the bag opening will prevent binding component one and binding component two from moving, thereby enabling the bag body to be positioned. Furthermore, when the sand inside the bag decreases, the sand at the bag opening can be replenished, allowing binding component one and binding component two to continue to position the bag body, thereby further improving stability and energy dissipation and impact prevention effects.

[0018] Optionally, the pocket opening includes an inner cuff and an outer cuff, the inner cuff being sewn to form a tightening hole; the fastening assembly includes: One fixing rope passes through the collection hole and can be used to securely tie the inner cuff; Secure the second rope by tying it to the outer cuff.

[0019] By adopting the above technical solution, when loading sand, the inner cuff is put onto the sand-filling equipment, the fixing rope is tightened and tied, so that the inner cuff is pressed against the sand-filling equipment for positioning, and the outer cuff is put onto the sand-filling equipment. Then, the outer cuff is tied and fixed onto the sand-filling equipment for positioning by the fixing rope. Therefore, by fixing the inner and outer cuffs together, the risk of sand overflow is reduced, and the sand-filling equipment can fill sand faster and with better effect.

[0020] After the sand is filled, untie the second fixing rope and the first fixing rope in sequence, take out the sand filling equipment, tighten the first fixing rope and tie it to secure it, thereby sealing the inner cuff. Then tie the outer cuff with the second fixing rope. During the tying process, the inner cuff is squeezed to achieve double sealing, which improves the sealing effect and the energy dissipation and anti-erosion effect of the sand rib bag.

[0021] Meanwhile, the fixed rope makes it easier to seal the inner cuff, and when closing the outer cuff, it can squeeze the inner cuff, so that the inner cuff is pressed tightly against the sand inside the cuff, making the sand inside the bag more compact. Through the combination of the two, it achieves both convenient binding and better energy dissipation and anti-impact effect.

[0022] Secondly, this application provides a construction method that adopts the following technical solution: A construction method includes the following construction steps: Once the hull is in place, the hull slabs are laid onto it. Install binding components and sandbags: Fix multiple binding components on the row body at the set positions, and then pass the sandbags through the multiple binding components; Filling: Connect multiple filling pipes connected to the mud pump to multiple bag openings respectively. Simultaneously fill the multiple bag openings with sand using the mud pump. After filling is completed, remove the filling pipes. Install connecting components: Securely install several connecting ropes to the connectors, and pass several connecting ropes through the tail end of the raft; when constructing the first raft, directly place the raft into the predetermined position in the water; when constructing subsequent rafts, lay the raft onto the hull and abut against the completed rafts, and pass the multiple connecting ropes located on the previous raft through the next raft and connector in sequence, so that the connector abuts against the next raft for positioning, tie the connecting ropes to secure the connector, and place the hull into the raft until the entire raft is placed on the water surface, then continue the construction of the next raft.

[0023] By adopting the above technical solution, the ballast body is laid on the hull, and multiple sets of lashing components 1 and 2 are fixedly installed on the ballast body. Sand rib bags are passed through the multiple sets of lashing components 1 and 2. Multiple filling pipes are fixedly connected to multiple bag openings respectively. Sand is simultaneously filled into multiple bag openings by a mud pump. After filling, the filling pipes are removed. The multiple sets of lashing components 1 and 2 press against the bag body, causing the bag body to form a depression for positioning. At the same time, the sand in the bag opening positions the lashing components 1 and 2, thus enabling the bag body to be positioned and improving the energy dissipation and erosion prevention effect.

[0024] Several connecting ropes are fixedly installed on the connectors and passed through the tail end of the raft. When constructing the first raft, it is directly placed in the water at the predetermined position. When constructing subsequent rafts, the rafts are laid on the hull and abutted against the completed rafts. The connecting ropes on the previous raft are passed through the next raft and the connectors in sequence, so that the connectors are positioned against the next raft. The connecting ropes are tied to secure the connectors. The hull is then lowered into the raft until the entire raft is placed on the water surface. Then the construction of the next raft continues, which improves the energy dissipation and scour prevention effect and construction efficiency.

[0025] Optionally, the hull is provided with auxiliary components, the auxiliary components including: A flap, which is rotatably mounted on the hull and used to place hulls when in a horizontal position; Clamping components are used to clamp and position one side of the assembly. A driving component is used to drive the flap to rotate; when filling, the driving component drives the flap to tilt, and the clamping component is used to clamp the top of the filling body and make the filling body tensioned under gravity.

[0026] By adopting the above technical solution, when the flap is in a horizontal state, it is convenient to lay the pavement on the flap, and the clamping parts clamp and position the pavement. During filling, the driving parts drive the flap to slowly rotate to an inclined state, and the pavement moves down under the action of gravity, so that the pavement is tensioned. After filling is completed, the clamping parts are released, so the pavement can slide into the water under the action of gravity, which greatly improves the convenience of putting the pavement into the water and tensioning it, and improves the construction efficiency and anti-erosion effect.

[0027] Optionally, the raft is provided with multiple underwater beacons for indicating its position.

[0028] By adopting the above technical solution, the position of the discharge body can be better displayed, making the position of the discharge body closer to the required position, thus improving the energy dissipation and anti-scour effect.

[0029] In summary, this application includes at least one of the following beneficial technical effects: 1. By filling multiple sand rib bags with sand and fixing them to the raft body, several connecting ropes are fixedly connected to the connectors and then passed through the tail end of the raft body. The connecting ropes located on the previous raft body are passed through the next raft body and fixedly connected to the connectors. Then, sand rib bags are fixedly installed on the next raft body, thereby fixing multiple raft bodies together and improving the energy dissipation and scour prevention effect.

[0030] 2. By filling the bag with sand simultaneously through multiple openings, the time spent filling the sand is greatly reduced; at the same time, the distance between the sand filling point and the inside of the bag is shortened, so that the sand can enter the bag more evenly and compactly, thus improving the energy dissipation and anti-erosion effect.

[0031] 3. The bag opening is supported by sand inside, and the binding assembly presses against the bag opening for positioning when the bag is tied to the row, which greatly improves the fixing effect of the bag. Furthermore, when the sand inside the bag decreases, the sand inside the bag opening can be replenished, so that the binding assembly can continue to position the bag, thereby further improving stability and energy dissipation and anti-impact effect.

[0034] The following provides a further detailed description of this application.

[0035] This application discloses a seawall anti-erosion structure with a sand rib pad layer filter structure.

[0036] Reference Figure 1 and Figure 2 The seawall anti-erosion structure with sand rib padding filter structure includes multiple rafts 1 and multiple sand rib bags 2 located on the rafts 1. Adjacent rafts 1 are connected to each other by a connecting component 3. The connecting component 3 includes several connecting ropes 31 and two connecting pieces 32. The several connecting ropes 31 pass through the two rafts 1 and are respectively connected to the two connecting pieces 32, so that the two connecting pieces 32 abut against the rafts 1 for positioning.

[0037] The connector 32 is a plate-shaped structure made of lightweight material, such as plastic, which allows the pressure of the connector 32 to be more evenly distributed on the drain body 1 when it abuts against it, thus improving the stability of the drain body 1. There are at least two connecting ropes 31, spaced apart along the length of the connector 32; the connecting ropes 31 pass through the connector 32, and two closely spaced connecting ropes 31 are fixedly tied together for positioning.

[0038] The connecting ropes 31 are made of metal, such as iron or aluminum. If there is an even number of connecting ropes 31, two adjacent connecting ropes 31 are grouped together and tied together for fixation. If there is an odd number of connecting ropes 31, the last remaining connecting rope 31 is tied to the previous group of connecting ropes 31 for fixation, thus greatly improving the convenience of the connection process. Multiple connecting ropes 31 are passed through one row body 1 and the connector 32 and tied together for fixation, so that the connector 32 is positioned against the row body 1. Then, the other end of the multiple connecting ropes 31 is passed through another row body 1 and the connector 32, pushing the two rows body 1 against each other and pushing the connector 32 against the row body 1 for positioning. Finally, the multiple connecting ropes 31 are tied together for fixation, thus achieving a fixed connection between two adjacent rows body 1.

[0039] Reference Figure 1 and Figure 3 The sand rib bag 2 includes a bag body 21 and multiple bag openings 22. The bag body 21 is used to fill sand, and whether the bag body 21 needs to be supplied with water is designed according to the needs. The bag body 21 is fixedly connected to the row body 1 by multiple binding components 4. The multiple bag openings 22 are spaced apart along the axis of the bag body 21, and the bag openings 22 are connected to the bag body 21. The bag openings 22 and the bag body 21 are sewn together with the same material. When filling sand, the sand moves into the bag openings 22 to support the bag openings 22. At the same time, when filling sand, sand is filled into the bag body 21 through the multiple bag openings 22, so that the sand moves into the bag openings 22 for support, and is fixed by binding components 5.

[0040] Multiple binding components 4 are provided one-to-one with multiple bag openings 22. The binding components 4 are located on both sides of the bag opening 22 and are positioned against the connection between the bag opening 22 and the bag body 21. The binding components 4 include binding element 1 41 and binding element 2 42. Binding element 1 41 and binding element 2 42 are the same and are both metal binding wires. Binding element 1 41 and binding element 2 42 pass through the row body 1 and around the bag body 21 for binding and fixing. Binding element 1 41 and binding element 2 42 are located on both sides of the bag opening 22 and are positioned against the connection between the bag opening 22 and the bag body 21. Since the bag opening 22 is filled with sand, binding element 1 41 and binding element 2 42 are positioned against the outside of the bag opening 22, thereby positioning the bag body 21.

[0041] Reference Figure 3 and Figure 4The pocket opening 22 includes an inner cuff 23 and an outer cuff 24. A tightening hole 25 is sewn into the top of the outer wall of the inner cuff 23. The fastening assembly 5 includes a first fastening cord 51 and a second fastening cord 52. The first fastening cord 51 passes through the tightening hole 25 and can securely tie the inner cuff 23. Both ends of the first fastening cord 51 can be knotted after passing through the tightening hole 25 to prevent it from falling out. The inner cuff 23 is located inside the outer cuff 24 and is shorter than the outer cuff 24. The second fastening cord 52 is tied to the outer wall of the outer cuff 24 for fixation.

[0042] When filling with sand, the inner cuff 23 is fitted onto the sand filling equipment, the fixing rope 1 51 is tightened and tied in place, so that the inner cuff 23 is pressed against the sand filling equipment for positioning, and the outer cuff 24 is fitted onto the sand filling equipment, and then the outer cuff 24 is tied and fixed onto the sand filling equipment for positioning by the fixing rope 2 52. Therefore, the inner cuff 23 and the outer cuff 24 are fixed together, thereby reducing the risk of sand overflow; at the same time, the binding parts 1 41 and 2 42 are pressed against the bag body 21 and the bag body 21 is concave for positioning, and multiple bag openings 22, multiple binding parts 1 41 and multiple binding parts 2 42 simultaneously position the bag body 21.

[0043] After the sand is filled, untie the second fixing rope 52 and the first fixing rope 51 in sequence, take out the sand filling equipment, tighten the first fixing rope 51 and tie it to secure it, thereby sealing the inner cuff 23. Then tie the outer cuff 24 with the second fixing rope 52. During the tying process, the inner cuff 23 is squeezed to achieve double sealing, which improves the sealing effect and the energy dissipation and anti-impact effect of the sand rib bag 2.

[0044] The working principle of this application embodiment is as follows: Lay the liner 1 onto the hull 11. Securely install multiple sets of binding clips 41 and 42 onto the liner 1. Place the bag 21 onto the liner 1, aligning multiple bag openings 22 with the binding clips 41 and 42, and pass the bag openings 22 between the binding clips 41 and 42. Extend the filling device into the multiple bag openings 22. Secure the inner cuff 23 and outer cuff 24 to the filling device using fixing ropes 51 and 52. The filling equipment simultaneously fills the bag body 21 with sand through multiple bag openings 22, ensuring that the inner cuff 23 is filled with sand. Then, the second fixing rope 52 and the first fixing rope 51 are untied in sequence, and the first fixing rope 51 is tightened for binding and fixing. The outer cuff 24 is bound and fixed by the second fixing rope 52. During the binding process, the outer cuff 24 is pressed against the inner cuff 23 for positioning. At the same time, the first binding piece 41 and the second binding piece 42 fix the bag body 21, improving the stability of the bag body 21.

[0045] After passing multiple connecting ropes 31 through the connector 32, they are tied and fixed. The multiple connecting ropes 31 are then passed through the tail end of the raft body 1. When constructing the first raft body 1, the raft body 1 is directly placed in the water at the predetermined position. When constructing subsequent raft bodies 1, the raft body 1 is laid on the hull 11 and rests against the completed raft body 1. The multiple connecting ropes 31 located on the previous raft body 1 are passed through the next raft body 1 and the connector 32 in sequence, so that the connector 32 rests against the next raft body 1 for positioning. The connecting ropes 31 are tied and fixed to the connector 32. The hull 11 is placed into the raft body 1 until the entire raft body 1 is placed on the water surface. Then the construction of the next raft body 1 continues, which improves the energy dissipation and anti-erosion effect and construction efficiency.

[0046] This application discloses a construction method.

[0047] Reference Figures 1-5 The construction method includes the following construction steps: Hull 11 is in place, and hull 1 is laid on hull 11; Install the binding assembly 4 and the sand rib bag 2: Fix multiple binding assemblies 4, namely multiple sets of binding piece 1 41 and binding piece 2 42, on the row body 1 according to the set position. Then, pass the sand rib bag 2 through the multiple sets of binding piece 1 41 and binding piece 2 42. The multiple bag openings 22 are aligned with the multiple sets of binding piece 1 41 and binding piece 2 42, and the bag openings 22 pass through the binding piece 1 41 and binding piece 2 42. Filling: Multiple filling pipes connected to the mud pump are fixedly connected to multiple bag openings 22 via fixing components 5. During filling, the inner cuff 23 and the outer cuff 24 are fixedly installed on the outer wall of the filling pipe via fixing components 5 for positioning. Sand is simultaneously filled into multiple bag openings 22 by the mud pump. After filling is completed, the filling pipes are removed, so that the binding piece 1 41 and binding piece 2 42 press against the bag body 21 and cause the bag body 21 to be recessed for positioning. At the same time, the binding piece 1 41 and binding piece 2 42 press against the bag openings 22 for positioning. Install connecting component 3: Fix multiple connecting ropes 31 to the connector 32, and pass multiple connecting ropes 31 through the tail end of the raft body 1; when constructing the first raft body 1, directly place the raft body 1 into the predetermined position in the water; when constructing subsequent raft bodies 1, lay the raft body 1 on the hull 11 and abut against the completed raft body 1, pass multiple connecting ropes 31 located on the previous raft body 1 through the next raft body 1 and the connector 32 in sequence, so that the connector 32 abuts against the next raft body 1 for positioning, tie the connecting ropes 31 to fix the connector 32, put the hull 11 into the raft body 1 until the raft body 1 is completely placed on the water surface, and then continue the construction of the next raft body 1.

[0048] Multiple underwater beacons for indicating position are detachably installed on the raft body 1. During the construction of the raft body 1, the underwater beacons that are no longer in use can be removed and reused.

[0049] Reference Figure 5 , Figure 6 An auxiliary component 6 is provided on the hull 11. The auxiliary component 6 includes a flap 61, a clamping member 62, and a driving member 63. The flap 61 is rotatably mounted on the hull 11 via a rotating shaft. When the flap 61 is in a horizontal state, the paving body 1 is laid on the flap 61 for positioning. The clamping member 62 is located on the side of the flap 61 away from the rotating shaft and is used to clamp and position the paving body 1. The clamping member 62 can be a cylinder or a clamping plate. The driving member 63 is a motor. The driving member 63 is fixedly mounted on the hull 11 and is used to drive the rotating shaft to rotate.

[0050] During filling, the drive unit 63 drives the flap 61 to tilt. The angle of the flap 61 can be 35 degrees, etc. The clamping member 62 is used to clamp the top of the pump body 1, so that the pump body 1 can be tensioned under gravity. At the same time, when filling is completed and the pump body 1 is put into the water, the clamping member 62 releases the clamp, and the pump body 1 can also slide down to the water surface under the action of gravity.

[0051] The working principle of this application embodiment is as follows: The flap 61 is rotated to a horizontal position, and the bag body 1 is laid on the flap 61. The clamping member 62 clamps and positions the bag body 1. Multiple sets of binding members 1 41 and binding members 2 42 are fixedly tied to the bag body 1. The bag body 21 is passed through the binding members 1 41 and binding members 2 42, and each bag opening 22 is aligned with each set of binding members 1 41 and binding members 2 42, so that the bag opening 22 passes between the binding members 1 41 and binding members 2 42 and extends above them. The filling tube is fixed to the multiple bag openings 22 by the fixing component 5. The drive unit 63 starts the drive flap 61 to tilt, and at the same time the mud pump starts to fill the bag body 21 with sand through multiple bag openings 22 until the bag is full. The discharge body 1 is tensioned under the action of gravity. Then the filling pipe is removed and the bag opening 22 is tied to fix it. At the same time, the binding parts 1 and 2 are pressed against the bag body 21 and form a depression for positioning. Meanwhile, the sand in the bag opening 22 can also position the bag body 21, thereby improving the energy dissipation and anti-scour effect.

[0052] Multiple connecting ropes 31 are fixedly installed onto the connector 32. The multiple connecting ropes 31 are passed through the tail end of the raft body 1. When the first raft body 1 is constructed, the clamp 62 is released and the hull 11 moves, so that the raft body 1 is placed in the predetermined position in the water. When the subsequent raft body 1 is constructed, the raft body 1 is laid on the flip plate 61 and abutted against the raft body 1 that has been constructed. The multiple connecting ropes 31 located on the previous raft body 1 are passed through the next raft body 1 and the connector 32 in sequence, so that the connector 32 abuts against the next raft body 1 for positioning. The connecting ropes 31 are tied to fix the connector 32. The hull 11 is placed into the raft body 1 until the entire raft body 1 is placed on the water surface. Then the construction of the next raft body 1 continues, which improves the energy dissipation and anti-erosion effect.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
