[0001] The present application relates to the technical field of seawall reinforcement, in particular to a seawall toe reinforcement structure and a construction method thereof. BACKGROUND

[0002] A seawall, also known as a vertical seawall, is a wall built with stones or slates to prevent tides and waves.

[0003] According to the search, a seawall structure disclosed in a Chinese patent with the authorization publication number CN111979971A includes a pile body, a gravel layer arranged along the pile body from bottom to top, and a base body. The base body includes a bottom plate, a top plate, and a jacking assembly. The top plate is slidably connected to the bottom plate in the vertical direction.

Filler can be added into the inner cavity of the first telescopic column through the filler hole.

[0004] According to the above related technology, the inventors believe that the seawall structure has the effect of reducing settlement, but the seawall face is easily damaged by wind and wave erosion, which needs to be improved. SUMMARY

[0005] In order to improve the ability of the seawall face to resist wind and wave erosion, the seawall toe reinforcement structure and the construction method thereof are provided.

[0006] The seawall toe reinforcement structure includes:

[0007] The wave blocking assembly includes a flow resistance pile, and the flow resistance pile is arranged on the seawall face side.

[0008] The wave blocking assembly further includes a floating member, and the floating member is arranged on the top of the flow resistance pile.

[0009] The limiting assembly has one end fixedly connected to the floating member, and the other end is used for installation connection with the seawall.

[0010] By adopting the technical scheme, when the wind and waves hit the seawall, the flow resistance pile can reduce the scouring ability of the wind and waves and delay the scouring time of the wind and waves; on the one hand, the wave blocking plants are planted on the floating member, and the floating member is arranged on the top of the flow resistance pile, so that the wave blocking plants can also block and delay the wind and waves, weaken the destruction of the wind and waves to the seawall, on the other hand, the wave blocking plants can improve the ornamental and environmental protection of the seawall; at the same time, the limiting assembly connects the seawall and the wave blocking assembly into a whole, which can improve the overall performance of the seawall, the wave blocking assembly and the wave blocking plants, and the limiting assembly, the seawall and the wave blocking assembly are movably connected, so that the displacement change caused by the wind and waves can be adapted, the overall performance of the seawall, the wave blocking assembly and the wave blocking plants is further optimized, and finally the scheme has the effects of reinforcing the seawall embankment and improving the ability of the seawall to resist the scouring of the wind and waves.

[0011] Optionally, the limiting assembly comprises a first filter plate and a second filter plate, the first filter plate is in the shape of a channel steel, displacement grooves are formed in the opposite side of the two wings of the first filter plate, the second filter plate is provided with a matching shaft corresponding to the displacement grooves, and the matching shaft is rotatably and slidably arranged in the displacement grooves.

[0012] By adopting the technical scheme, in the process that the wind and waves hit the seawall, the wind and waves first act on the surfaces of the first filter plate and the second filter plate, the first filter plate and the second filter plate then relatively displace and also relatively rotate, so that the wind and waves can be adaptively blocked from scouring the seawall, and the scouring ability of the wind and waves is also weakened due to the filtering effect of the first filter plate and the second filter plate. The surfaces of the first filter plate and the second filter plate can be paved with suitable lawns or green plants to improve the ornamental property.

[0013] Optionally, the top of the seawall is provided with a fixing seat, one end of the first filter plate away from the second filter plate is provided with a reset torsional spring, and the first filter plate is rotatably connected to the fixing seat through the reset torsional spring.

[0014] By adopting the technical scheme, as the tide recedes, the first filter plate rotates and resets under the action of the reset torsional spring, and the second filter plate also rotates and resets, so that the limiting assembly resets to the original state.

[0015] Optionally, the flow resistance pile is a pipe pile, and an installation groove is formed in the inner wall of the flow resistance pile.

[0016] The floating member comprises a sponge seat, a planting hole is formed in the sponge seat in the axial direction relative to the flow resistance pile, and the bottom of the wave blocking plant abuts against the inner wall of the planting hole and penetrates into the interior of the flow resistance pile.

[0017] A clamping block is arranged on the outer peripheral wall of the sponge seat and corresponds to the installation groove, and the clamping block is embedded in the installation groove.

[0018] By adopting the technical scheme, the wave-blocking plant is installed by abutting the bottom of the wave-blocking plant against the inner wall of the planting hole and embedding the clamping block of the sponge seat in the mounting groove. Under the action of the wall in the mounting groove, the clamping block is not easy to be separated from the mounting groove, and thus the sponge seat and the wave-blocking plant are not easy to be separated from the flow resistance pile under the action of the wind and waves. With the growth of the wave-blocking plant, the wave-blocking plant stably grows and roots in the flow resistance pile.

[0019] Optionally, the flow resistance pile is filled with a nutrient soil layer, and the wave-blocking plant roots in the nutrient soil layer.

[0020] By adopting the technical scheme, since the flow resistance pile is a pipe pile, the flow resistance pile can be filled with a nutrient soil layer, and thus the wave-blocking plant can root in the nutrient soil layer to absorb nutrients and grow vigorously to improve the growth and ornamental nature of the wave-blocking plant.

[0021] Optionally, the floating member further comprises a displacement sleeve, and the displacement sleeve is slidingly sleeved on the outer wall of the flow resistance pile.

[0022] The outer wall of the displacement sleeve is provided with a fixing block, and the fixing block is detachably connected to the end of the second filter plate away from the first filter plate.

[0023] By adopting the technical scheme, during the process that the wind and waves hit the water surface of the seawall, the wind and waves cause the first filter plate and the second filter plate to relatively displace and relatively rotate, drive the displacement sleeve to axially displace upward, and thus increase the protection range of the displacement sleeve on the wave-blocking plant and enhance the protection effect of the displacement sleeve on the wave-blocking plant. The detachable connection of the fixing block and the second filter plate facilitates the disassembly and assembly of the second filter plate and the displacement sleeve.

[0024] Optionally, the outer wall of the flow resistance pile is provided with a guide groove penetrating through the top, the inner wall of the displacement sleeve is provided with a guide strip corresponding to the guide groove, and the guide strip is slidingly embedded in the guide groove.

[0025] By adopting the technical scheme, the side wall of the guide groove has a guide groove effect on the guide strip, and thus the displacement sleeve is stably axially displaced, and the bottom wall of the guide groove has a supporting effect on the displacement sleeve.

[0026] The construction method of the seawall toe reinforcement structure comprises the following steps:

[0027] S1, inserting the flow resistance pile into the riverbed on the water side of the seawall;

[0028] S2, planting the wave-blocking plant on the floating member and installing the floating member on the top of the flow resistance pile;

[0029] S3, fixedly installing one end of the limiting assembly on the floating member and rotatably installing the other end of the limiting assembly on the seawall.

[0030] By adopting the technical scheme, the flow resistance pile can be punched and set during the construction of the seawall, and the flow resistance pile can play a role in resisting waves and tides in advance. When the tide rises and falls, the flow speed of the wind and waves can be reduced to protect the seawall. The floating member, the wave blocking plant and the limiting assembly can be installed later, and the ability of the seawall to resist wind and wave erosion can be further improved.

[0031] In summary, the present application includes at least one of the following beneficial technical effects:

[0033] 2. The first filter plate and the second filter plate will be relatively displaced and rotated, thereby adaptively blocking the wind and wave erosion of the seawall.

[0034] 3. The first filter plate and the second filter plate are relatively displaced and rotated, driving the displacement sleeve to axially displace upward, thereby increasing the protection range of the displacement sleeve to the wave blocking plant and enhancing the protection effect of the displacement sleeve to the wave blocking plant.

[0044] The following description will be made in conjunction with the accompanying drawings Figures 1-4 The application is further described in detail.

[0045] The application discloses a seawall embankment reinforcing structure, referring to Figure 1 The bottom of the seawall 1 is formed with a reinforced embankment part 11. On the one hand, the reinforced embankment part 11 is arranged along the length direction of the seawall 1; on the other hand, the reinforced embankment part 11 is vertically away from the seawall 1.

[0046] A seawall embankment reinforcing structure comprises a wave blocking mechanism, the wave blocking mechanism has a plurality of and is uniformly and spacedly arranged along the length direction of the seawall 1. Any wave blocking mechanism comprises a wave blocking assembly 2, a wave blocking plant 3 and a limiting assembly 4, the wave blocking plant 3 is planted on the wave blocking assembly 2, and the wave blocking assembly 2 and the wave blocking plant 3 are arranged on the water side of the seawall 1. The limiting assembly 4 is obliquely downwardly arranged, one end of the limiting assembly 4 is connected to the top of the seawall 1, and the other end of the limiting assembly 4 is fixedly connected to the wave blocking assembly 2. The whole formed by the wave blocking plant 3, the wave blocking assembly 2 and the limiting assembly 4 has the effect of delaying and weakening the wind wave, and cooperates with each other to protect the seawall 1. The wave blocking plant 3 not only can block waves and prevent moisture, but also has a certain ornamental property.

[0047] Referring to Figure 1 , Figure 2 The limiting assembly 4 comprises a first filter plate 41, a second filter plate 42 and a fixing seat 45, and the bottom of the fixing seat 45 is fixedly connected to the top of the seawall 1. The fixing seat 45 is in the shape of a channel steel, two wings of the first filter plate 41 are respectively fixedly connected with reset torsional springs 46 on the opposite sides, and the first filter plate 41 is rotatably connected with the opposite sides of the two wings of the fixing seat 45 through the reset torsional springs 46.

[0048] The opposite sides of the two wings of the first filter plate 41 are respectively provided with displacement slots 44, the displacement slots 44 are away from the reset torsional springs 46 and close to the second filter plate 42. The displacement slots 44 are extended along the length direction of the wings of the first filter plate 41, and the displacement slots 44 do not penetrate through the first filter plate 41; the displacement slots 44 comprise a first slot with a semicircular cross section and a second slot with a rectangular cross section, and the first slot, the second slot and the groove of the first filter plate 41 are sequentially communicated.

[0049] One end of the second filter plate 42 is located between the two wing plates of the first filter plate 41, and the other end of the second filter plate 42 is located outside the first filter plate 41. The second filter plate 42 is fixedly connected to two sets of displacement grooves 44, respectively, with mating shafts 43. The end of the mating shaft 43 away from the second filter plate 42 conforms to the shape of the hemispherical first groove, allowing the mating shaft 43 to be rotatably connected to the displacement groove 44. Except for the end conforming to the shape of the first groove, the remaining part of the mating shaft 43 is cylindrical and abuts against the inner wall of the second groove. When the mating shaft 43 moves and rotates along the first groove, the side wall of the second groove guides and limits the mating shaft along the length of the displacement groove, so that the first filter plate 41 and the second filter plate 42 rotate relative to each other while undergoing relative displacement.

[0050] Both the first filter plate 41 and the second filter plate 42 have water passage holes, which are evenly distributed on the first filter plate 41 or the second filter plate 42. The water passage holes can reduce the weight of the first filter plate 41 and the second filter plate 42, improve the integrity of the limiting component 4, and increase the surface area of ​​the first filter plate 41 or the second filter plate 42 on the inner wall of the water passage holes. When encountering wind and waves, they can delay the time when the wind and waves hit the seawall 1, reduce the ability of the wind and waves to erode the seawall 1, and reduce the damage of the wind and waves to the first filter plate 41 or the second filter plate 42.

[0051] Reference Figure 1 , Figure 3 The wave-blocking component 2 includes a flow-blocking pile 21 and a floating component. The floating component includes a sponge seat 22 and a displacement sleeve 23. A semi-circular hole 12 is opened from top to bottom through the end of the reinforced dike toe 11 away from the seawall 1. The flow-blocking pile 21 is pressed against the inner circumferential wall of the semi-circular hole 12 and passes through the semi-circular hole 12. The bottom end of the flow-blocking pile 21, located below the semi-circular hole 12, is inserted into the riverbed, and the top end of the flow-blocking pile 21 is located above the semi-circular hole 12. The semi-circular hole 12 reduces the damage to the reinforced dike toe 11. At the same time, the inner wall of the semi-circular hole 12 can circumferentially limit the flow-blocking pile 21 and connect the flow-blocking pile 21 to the seawall 1 as a whole, reducing the degree of freedom of the flow-blocking pile 21 outside the riverbed and improving the stability of the flow-blocking pile 21.

[0052] The flow-blocking pile 21 can be made of steel pipe pile. The pipe hole of the flow-blocking pile 21 is rectangular. The four vertical surfaces of the inner wall of the flow-blocking pile 21 are respectively provided with installation grooves 211. The four installation grooves 211 are evenly spaced along the circumference of the flow-blocking pile 21. The vertical surface of the installation groove 211 is a trapezoid with a small opening at the top and a large opening at the bottom. Each installation groove 211 extends through the top of the flow-blocking pile 21.

[0053] The sponge seat 22 is shaped to match the inner hole wall of the block 21. The sponge seat 22 is fixedly connected with a clamping block 222 corresponding to any mounting groove 211, and the shape of the clamping block 222 matches the shape of the mounting groove 211. Each clamping block 222 is respectively embedded in the corresponding mounting groove 211. At this time, the lower part of the sponge seat 22 is located in the block 21, and the upper part of the sponge seat 22 is located above the block 21.

[0054] The bottom wall of the mounting groove 211 supports the clamping block 222, and because the side wall of the mounting groove 211 is obliquely matched with the clamping block 222, when subjected to an axial upward force, the sponge seat 22 is not easy to separate.

[0055] The sponge seat 22 is selected from a block of sponge material, and the sponge has the ability to deform and recover. The sponge seat 22 located in the block 21 is in a compressed state. The sponge seat 22 in this state has a radial extrusion effect on the block 21, which makes the clamping block 222 not easy to separate radially from the mounting groove 211, and is not affected during installation.

[0056] The sponge seat 22 is axially provided with a planting hole 221 relative to the block 21. The wave-blocking plant 3 abuts against the inner wall of the planting hole 221 and passes through the planting hole 221. As the wave-blocking plant 3 grows, the diameter of the wave-blocking plant 3 increases, and the inner wall of the planting hole 221 is adaptively extruded. At this time, the radial stability of the clamping block 222 can be further enhanced. Moreover, because the sponge seat 22 is in a compressed state, it has a radial extrusion effect on the peripheral wall of the wave-blocking plant 3, so the stability of the wave-blocking plant 3 can also be enhanced.

[0057] The block 21 is provided with a guide groove 212 axially from top to bottom through the top. The guide groove 212 is a T-shaped groove, and the guide groove 212 has four groups and is uniformly and circumferentially spaced apart along the block 21. The inner wall of the displacement sleeve 23 is fixedly connected with a guide strip 232 corresponding to any guide groove 212. The shape of the guide strip 232 matches the shape of the guide groove 212, and each guide strip 232 is respectively and slidingly embedded in the corresponding guide groove 212. Because the guide groove 212 is provided with four groups, the displacement sleeve 23 is not easy to be circumferentially deviated, and has a stable guiding property.

[0058] The displacement sleeve 23 is fixedly connected with a fixed block 231 towards the peripheral wall of the second filter plate 42. The fixed block 231 is provided with a fastener 47, and the fastener 47 is a bolt and a nut. The fixed block 231 is detachably connected with the second filter plate 42 through the fastener 47.

[0059] The locking block 222 is located at the lower part of the peripheral wall of the sponge seat 22, and the upper part of the peripheral wall of the sponge seat 22 is fixedly connected to the guide block 223. There are four sets of guide blocks 223, and each set of guide blocks 223 is located above the corresponding locking block 222. The guide blocks 223 are placed on the top surface of the flow-blocking pile 21. The guide block 223 is in the shape of a channel steel, and the guide strip 232 is slidably embedded in the groove of the guide block 223. The side of the web of the guide block 223 away from the wing plate is fixed to the sponge seat 22, and the web of the guide block 223 and the same side of the wing plate have a first inclined surface 224.

[0060] The lower part of the guide strip 232 is located within the guide groove 212, and the upper part of the guide strip 232 is slidably connected to the inner wall of the groove of the guide block 223. Simultaneously, the guide strip 232 has a second inclined surface 233 that corresponds to the first inclined surface 224, and the first inclined surface 224 and the second inclined surface 233 slide in contact. When the displacement sleeve 23 moves upward, the first inclined surface 224 and the second inclined surface 233 move relative to each other, causing the four sets of guide blocks 223 to move radially closer together, further strengthening the stability of the sponge seat 22 and the wave-blocking plant 3.

[0061] Reference Figure 1 , Figure 4 The flow-blocking pile 21 is filled with a nutrient soil layer 5. The top of the nutrient soil layer 5 is in contact with the bottom surface of the sponge seat 22. The end of the wave-blocking plant 3 located below the sponge seat 22 extends into the nutrient soil layer 5, allowing the wave-blocking plant 3 to absorb sufficient nutrients for its growth. The sponge seat 22 is in a compressed state, which can also effectively prevent debris or pollutants in the wave water from entering the flow-blocking pile 21 and contaminating the nutrient soil layer 5.

[0062] This application also discloses a construction method for reinforcing seawall toe structures, which includes the following steps:

[0063] S1, Install wave-blocking component 2;

[0064] S1-1, Using a pile driving device, the flow-blocking pile 21 is driven into the riverbed along the axial direction of the semi-circular hole 12.

[0065] S1-2, Use pumping equipment to remove the water accumulated inside the flow-blocking pile 21;

[0066] S1-3, fill the nutrient soil from the top of the flow-blocking pile 21 inward to form a nutrient soil layer 5;

[0067] S1-4, the sponge seat 22 is fitted onto the periphery of the stem of the wave-blocking plant 3, the sponge seat 22 is compressed appropriately, and the sponge seat 22 is placed inside the flow-blocking pile 21. Under the action of the deformation recovery of the sponge seat 22, the locking block 222 is embedded in the installation groove 211. At this time, the guide block 223 abuts against the top surface of the flow-blocking pile 21.

[0068] S1-5, slidingly embed the guide strip 232 into the guide groove 212, at this time the displacement sleeve 23 is sleeved on the outer peripheral wall of the block pile 21, the first inclined surface 224 and the second inclined surface 233 are in abutting cooperation;

[0069] S2, install the limiting assembly 4;

[0070] S2-1, assemble and connect the first filter plate 41 and the second filter plate 42, so that the first filter plate 41 and the second filter plate 42 can rotate and displace simultaneously;

[0071] S2-2, use the fastener 47 to fixedly connect the fixed block 231 and the second filter plate 42;

[0072] S2-3, position the fixed seat 45 on the top of the seawall 1;

[0073] S2-4, use the reset torsional spring 46 to install and connect the second filter plate 42 and the fixed seat 45.

[0074] The principle of the embodiment is as follows:

[0075] When the tide rises or the wind wave hits, the wind wave hits the first filter plate 41 or the second filter plate 42, so that the first filter plate 41 or the second filter plate 42 obtains a downward force, and the first filter plate 41 and the second filter plate 42 thus relatively rotate and displace. The first filter plate 41 and the fixed block 231 are detachably fixed by the fastener 47, and thus the second filter plate 42 drives the displacement sleeve 23 to axially displace upward to protect the wave-blocking plant 3. The displacement sleeve 23 axially displaces upward, and under the interaction of the first inclined surface 224 and the second inclined surface 233, the four guide blocks 223 radially converge along the planting hole 221, thereby circumferentially extruding and stabilizing the wave-blocking plant 3, improving the ability of the wave-blocking plant 3 to resist the wind wave, and reducing the damage of the wind wave to the wave-blocking plant 3.

[0076] When the tide recedes or the wind wave stops, under the action of the reset torsional spring 46, the first filter plate 41 and the second filter plate 42 reset, the displacement sleeve 23 resets with the second filter plate 42, the first inclined surface 224 and the second inclined surface 233 also reset, and the ability of the sponge seat 22 to stabilize the wave-blocking plant 3 is weakened to cooperate with the normal growth of the wave-blocking plant 3. With the decrease of the compression amount of the sponge seat 22, the water seeping into the block pile 21 and the sundries in the wave water can be effectively excluded from the polluted nutrient soil layer 5.

[0077] The embodiment uses the wave-blocking plant 3 as part of the wave-blocking and moisture-proof during construction, and the wave-blocking plant 3 has the functions of carbon absorption, energy saving and emission reduction, and environmental protection, which conforms to the concept of green construction.

[0078] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: all equivalent changes made according to the structure, shape, principle of the present application should be covered in the protection scope of the present application.
