Description

A flexible anti-erosion and siltation structure for use in areas with strong tidal surges Technical Field

[0001] This invention relates to the field of river siltation protection technology, specifically to a flexible anti-erosion and siltation structure for use in areas with strong tidal surges. Background Technology

[0002] In areas with strong tidal bores, the tidal bore and current are powerful when it arrives, scouring the riverbed at the bottom of the channel. In particular, the area around underwater structures is easily eroded, which can even affect the stability and safety of the structure's foundation.

[0003] For easily eroded areas such as the front of the dikes in the river channel and the surrounding areas of underwater structures, in order to ensure their safe operation, the foundation needs to be extended to a depth of more than ten meters, or even tens of meters, below the bed surface to maintain the safety of the structures. The methods used for protection and siltation promotion are mostly anti-erosion block structures such as riprap and concrete twisted blocks. For anti-erosion and siltation promotion schemes in river areas, most of the materials used are difficult to obtain and construct, resulting in low efficiency and poor protection and siltation promotion capabilities.

[0004] In the prior art, for example, the US patent application number US20130071185A1 discloses a concrete structure for erosion protection of riverbanks and coastlines. It uses a combination of hollow cones and concrete slabs as a throwing protection structure. When this construction structure is used in areas with strong water flow such as tidal surges, it is easily washed away by the water flow due to its poor structural stability, thus providing little protection. In addition, it has poor siltation promotion ability, and the efficiency of splicing and throwing prefabricated components is also low. It is difficult to meet the requirements for use as a protective siltation promotion throwing structure in areas with strong tidal surges.

[0005] A Taiwanese invention patent with application number TWI429808B discloses a riverbed erosion reduction and siltation promotion device. It uses an integral structure with a flow-dispersing belt mounted on a frame-like protective support as a throwing component. However, this device structure itself is relatively lightweight and is easily dispersed when the water flow velocity is high. Furthermore, the assembly workload is large and the construction efficiency is poor. When used in areas with low water flow velocity, the flow-dispersing belt has a certain effect on slowing down the flow velocity of silt, fine sand and other debris in the water flow, but the intercepted silt and sand cannot achieve the desired aggregation effect. The flow-dispersing belt is relatively dispersed and has poor deceleration effect on high-velocity river water. The energy consumption of the flow-dispersing belt and the siltation promotion capacity are difficult to meet the requirements for use in waters with high flow velocities such as strong tidal surges. Summary of the Invention

[0006] The purpose of this invention is to provide a flexible anti-scouring and siltation structure for use in areas with strong tidal currents, which can reduce the impact of water flow scouring in areas with high flow velocities such as strong tidal surges and promote silt accumulation and deposition protection.

[0007] The technical solution adopted by the present invention to achieve the above objectives is as follows:

[0008] Preferably, a flexible anti-erosion and siltation promoting structure for strong tidal waters includes a reinforced concrete block and a siltation promoting component. The reinforced concrete block has a regular tetrahedral structure, and the siltation promoting component is disposed on at least one surface of the reinforced concrete block.

[0009] Preferably, the flexible anti-erosion and siltation structure for strong tidal waters according to the claim is characterized in that the reinforced concrete blocks are precast reinforced concrete components, which are not easily washed away during mass throwing due to the self-adaptive characteristics of the tetrahedral stable structure. They can be thrown into the water on a large scale without fine splicing, making construction easier and throwing efficiency higher.

[0010] Preferably, in a flexible anti-erosion and siltation structure for strong tidal waters according to claim 1, the surface of the reinforced concrete block is provided with at least one groove.

[0011] A clearing and mounting hole is provided on the surface of the reinforced concrete block, leading to the vertex in the direction of the surface normal.

[0012] The groove is located at the end of the unblocking installation hole, and the center line of the unblocking installation hole is located inside the groove.

[0013] Preferably, the flexible anti-erosion and siltation structure for strong tidal waters according to the claim is characterized in that the siltation promoting component includes a fixed base fixedly connected in the groove, the number of fixed bases being directly proportional to the edge length of the reinforced concrete block, thereby reducing the possibility of impact damage to the structure body during the throwing process.

[0014] Preferably, the flexible anti-erosion and siltation structure for strong tidal waters according to the claim is characterized in that the height of the fixed base does not exceed the depth of the groove, the upper end of the fixed base is fixedly connected to the fixed top cover by bolts, the fixed top cover and the fixed base are provided with ball bearings on their opposite surfaces, and a fixed rod is slidably connected between the fixed base and the fixed top cover in the length direction of the groove. By pre-embedding the fixed base in the precast concrete component, the installation efficiency and stability of the structural component can be improved. The fixed rod can rotate and slide relative to the fixed base and the fixed top cover through the ball bearings, which improves the responsiveness to consuming water kinetic energy.

[0015] Preferably, according to the claim, a flexible anti-erosion and siltation-promoting structure for strong tidal waters is characterized in that the fixing rod is slidably connected with at least one set of fixing clamps in the length direction, the number of fixing clamps in each set is proportional to the length of the fixing rod, and a simulated aquatic plant strip is fixedly connected to each set of fixing clamps; the simulated aquatic plant strip and the block structure improve the anti-erosion capability. When the water flow velocity is low, the simulated aquatic plant strip floats under the action of buoyancy, and the degree of collapse is small. This reduces the water flow velocity and deposits silt, sand and other debris in the water flow at the structural components, thereby improving the overall siltation-promoting capability of the structure.

[0016] Preferably, according to the claim, a flexible anti-scouring and silt-promoting structure for tidal bore waters is characterized in that an auxiliary component is provided in the groove, the auxiliary component including a fixed sleeve fixedly connected in the groove, a torsion spring fixedly connected in the fixed sleeve, a connecting sleeve fixedly connected to the left end of the torsion spring, the connecting sleeve being able to slide in the fixed sleeve through the torsion spring fixedly connected thereto, a locking screw being rotatably connected to the upper end of the connecting sleeve, and the connecting sleeve being connected to one end of a fixed rod; this improves the deceleration and energy dissipation effect of the silt-promoting component on the water flow, and effectively improves the overall protective ability of the structure against water flow impact and the silt deposition capacity in tidal bore waters.

[0017] Preferably, according to the claim, a flexible anti-erosion and siltation structure for strong tidal waters is characterized in that a dredging structure is provided in the dredging installation hole, the dredging structure including an impact top ring and a flow guide cone sleeve disposed in the dredging installation hole, the flow guide cone sleeve being fixedly connected in the dredging installation hole and disposed near the apex of the reinforced concrete block, and the impact top ring being slidably connected in the dredging installation hole on one side near the equilateral triangular face of the reinforced concrete block.

[0018] Preferably, according to the claim, a flexible anti-scouring and silt-promoting structure for strong tidal waters is characterized in that the dredging installation hole is provided with a fixed bottom ring connected to the impact top ring, and a dredging spring and an isolation sealing sleeve are fixedly connected between the fixed bottom ring and the impact top ring, with the isolation sealing sleeve located inside the dredging spring.

[0019] Preferably, according to the claim, a flexible anti-scour and siltation promoting structure for strong tidal waters is characterized in that a connecting shaft is fixedly connected to the lower end face of the impact top ring, the fixed bottom ring is slidably engaged with the connecting shaft, the connecting shaft is located between the isolation sealing sleeve and the unblocking spring, and an unblocking pusher is fixedly connected to the end face of the connecting shaft. The unblocking pusher cooperates with the inner wall of the guide cone sleeve, thereby improving the efficiency of the siltation promoting structure and improving the enrichment effect and quality of the bottom silt at the accumulation point of the anti-scour and siltation promoting structure.

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] By incorporating reinforced concrete blocks and simulated aquatic plant blocks, the impact and damage of tidal currents on riverbanks or protected areas can be reduced at different flow velocities. The adaptive stability of the tetrahedral reinforced concrete blocks enhances scour resistance. Auxiliary components and locking screws link the connecting sleeve and fixing rod, improving the deceleration and energy dissipation effect of the silt-promoting components on the water flow. This effectively enhances the overall structural protection against water flow impact and silt deposition capacity within tidal waters. Furthermore, the dredging structure utilizes water flow dynamics to drive the dredging pusher through the silt accumulated within the blocks, promoting its efficient use and improving the silt deposition protection effect at the bottom of the scour-resistant silt-promoting structure accumulation area.

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] The concepts involved in this application will first be described with reference to the accompanying drawings. It should be noted that the following descriptions of various concepts are only for the purpose of making the content of this application easier to understand and do not constitute a limitation on the scope of protection of this application; furthermore, the embodiments and features in the embodiments of this application can be combined with each other unless otherwise specified. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0035] Example 1

[0036] Referring to Figure 1, a flexible anti-erosion and siltation promoting structure for strong tidal waters includes a reinforced concrete block 10 and a siltation promoting component 20. The reinforced concrete block 10 has a regular tetrahedral structure, and the siltation promoting component 20 is disposed on at least one surface of the reinforced concrete block 10.

[0037] It should be noted that the reinforced concrete block 10 is a precast reinforced concrete component. During mass deployment, its tetrahedral stability and self-adaptive properties make it less susceptible to being washed away. It can be deployed on a large scale in water without the need for precise assembly, resulting in lower construction difficulty and higher deployment efficiency. Of course, the reinforced concrete block 10 can be, but is not limited to, a tetrahedral structure; it can also be a pentahedral, hexahedral, or other polyhedral structure. The silt-promoting component 20 is installed on the surface of the reinforced concrete block 10, enabling it to promote the deposition of silt and sand in the surrounding flowing water.

[0038] Referring to Figures 1, 2, and 6, each of the four equilateral triangular faces of the reinforced concrete block 10 has a groove 21, and each of the four equilateral triangular faces of the reinforced concrete block 10 has a dredging installation hole 11 leading to the vertex of the surface normal. The four grooves 21 are oriented in the direction of the normal to the midpoint of the edge of the reinforced concrete block 10 on the equilateral triangular face. Each of the four vertices of the reinforced concrete block 10 corresponds to only one groove 21. The design of the dredging installation hole 11 can balance the stress on each vertex and improve the structural stability. Specifically, it avoids the reinforced concrete block 10 having an overly sharp end, which could cause excessive stress on the end and damage to the end of the reinforced concrete block 10 when it is thrown to the bottom of the water and collides with objects in the water. In addition, the groove 21 design can realize the installation of the silt-promoting component 20, thus making the silt-promoting component 20 and the reinforced concrete block 10 fit together. The installation and fixation of the concrete block 10 is more secure, and the silt-promoting component 20 is set on the surface of the reinforced concrete block 10 through the groove 21. In this way, there are no protrusions on the reinforced concrete block 10, which avoids or reduces the possibility of other objects contacting the surface of the reinforced concrete block 10 and damaging the silt-promoting component 20. For example, when multiple reinforced concrete blocks 10 are thrown into the water, there is no contact between the surfaces of adjacent reinforced concrete blocks 10 without protrusions, and adjacent reinforced concrete blocks 10 will not be damaged. More importantly, the groove 21 and the unblocking installation hole 11 on the surface of the reinforced concrete block 10 can achieve an appropriate flow obstruction effect on the water flowing over the surface of the reinforced concrete block 10, reducing the flow speed of the fluid flowing over the surface of the reinforced concrete block 10. In this way, the silt and sand in the fluid are easily intercepted by the groove 21 and the silt-promoting component 20 installed on the groove 21.

[0039] It should be noted that the edge length of the reinforced concrete block 10 is 'a'. In this embodiment, the groove width of the groove 21 is 5~10cm, and should not be too large, otherwise the risk of damage will increase. The groove depth is about 5cm. The length 'b' of the groove 21 is related to the edge length 'a' of the reinforced concrete block 10, and b = [(√3 / 2) x a - 0.2)] m. The relationship between the length of the groove 21 and the edge length of the reinforced concrete block 10 can be seen from the formula.

[0040] Referring to Figures 3, 4, and 5, the silt-promoting component 20 includes four sets of fixed bases 22 fixedly connected in four grooves 21. The number of fixed bases 22 in each set is proportional to the edge length of the reinforced concrete block 10. Typically, the edge length of the reinforced concrete block 10 is about 1.5 to 3 meters. Removing the sharp points at the vertices of the tetrahedron can reduce the possibility of impact damage to the structure during the throwing process.

[0041] The height of each set of fixed bases 22 does not exceed the depth of the groove 21. Each fixed base 22 is bolted to a fixed top cover 24. Each pair of fixed top covers 24 and fixed bases 22 has ball bearings on their opposing surfaces. A fixed rod 25 is slidably connected between each of the four sets of fixed bases 22 and fixed top covers 24 along the length of the groove 21. Pre-embedding the fixed bases 22 within the precast concrete component improves the installation efficiency and stability of the structural component. The fixed rod can rotate and slide relative to the fixed bases 22 and fixed top covers 24 via ball bearings, improving the responsiveness to consuming water flow energy. Furthermore, the fixed rod 25 relative to the fixed bases 22... The rotation and sliding of the ball bearings between the 2 and the fixed top cover 24 helps to drive the rotation and sliding of the clamp 27 and the simulated aquatic plant belt 23 connected to it. This helps the simulated aquatic plant belt 23 to drive the movement of fluid and sediment around the groove 21, avoiding excessive accumulation of sediment near the groove 21, which would reduce the flow obstruction effect of the groove 21. Furthermore, the sliding and rotation of the simulated aquatic plant belt 23 helps to promote the delivery of sediment near the groove 21 to the periphery of the reinforced concrete block 10. This promotes the accumulation of sediment around the reinforced concrete block 10 and prevents excessive sediment accumulation near the groove 21 from burying the simulated aquatic plant 23 and reducing the swaying effect of the simulated aquatic plant 23.

[0042] Each of the four fixed rods 25 is slidably connected to a set of fixed clamps 27 along its length. The number of clamps 27 in each set is proportional to the length of the fixed rod 25. Each clamp 27 is fixedly connected to a simulated aquatic plant strip 23. The clamps 27 fix the simulated aquatic plant strip 23 and cause the rod 25 to sway with the water flow. When the current is strong and the water velocity is high, the simulated aquatic plant strip 23 group follows the water flow and falls down, working with the block structure to slow down the strong water flow and prevent erosion. When the water velocity is low, the simulated aquatic plant strip... 23 floats up under the action of buoyancy, and at this time the degree of collapse is small. The simulated aquatic plant strip 23 further reduces the water flow velocity and deposits silt, sand and other debris in the low-speed water flow at the structural parts. The accumulated silt deposits are superimposed, which improves the overall silt-promoting ability of the structure. The density of the simulated aquatic plant strip 23 is controlled by setting the number of each set of fixing clamps 27 to be proportional to the length of the fixing rod 25. This avoids the increase in cost due to the excessive amount of simulated aquatic plant strip 23, or the decrease in the silt deposition effect due to the insufficient amount of simulated aquatic plant strip 23.

[0043] Each of the four grooves 21 contains an auxiliary component 40. Each auxiliary component 40 includes four fixed sleeves 41 fixedly connected to the four grooves 21. The height of each fixed sleeve 41 matches that of the fixed rod 25. A torsion spring 42 is fixedly connected inside each fixed sleeve 41. A connecting sleeve 43 is fixedly connected to the left end of each torsion spring 42. Each connecting sleeve 43 can slide within the fixed sleeve 41 via the torsion spring 42 it is fixedly connected to. A locking screw 44 is rotatably connected to the upper end of each connecting sleeve 43. A fixed rod 25 is slidably connected inside each connecting sleeve 43. The locking screw 44 can engage to fix the relative position of the connecting sleeve 43 and the fixed rod 25. The connecting sleeve 43 transmits the linkage motion between the simulated aquatic plant strip 23 and the fixed rod 25 to the torsion spring. When the fixed rod 25 slides in the axial direction, it drives the torsion spring to slide within the fixed sleeve. The ball bearings between the fixed base 22 and the fixed top cover 24 improve the response effect. Under the elastic force of the torsion spring, it can return to its position when the flow velocity decreases. This improves the deceleration and energy dissipation effect of the siltation promoting component 20 on the water flow, and improves the deposition capacity of the simulated aquatic plant strip 23 on the accumulated silt. It effectively improves the overall structural component's ability to protect against water flow impact and silt deposition in tidal waters. Furthermore, it prevents excessive accumulation of silt near the groove 21, which would reduce the flow obstruction effect of the groove 21. At the same time, it promotes the accumulation of silt around the reinforced concrete block 10 and prevents excessive accumulation of silt near the groove 21 from burying the simulated aquatic plant 23, thus reducing the swaying effect of the simulated aquatic plant 23.

[0044] Example 2

[0045] Referring to Figures 6, 7, and 8, each of the four dredging installation holes 11 is equipped with a dredging structure 30. The four dredging structures 30 include four sets of impact top rings 31 and guide cone sleeves 39 disposed within the dredging installation holes 11. The four guide cone sleeves 39 are fixedly connected to the four dredging installation holes 11 near the apex of the reinforced concrete block 10. The four impact top rings 31 are slidably connected to the side of the dredging installation hole 11 near the equilateral triangular face of the reinforced concrete block 10. By setting the guide cone sleeves 39 within the dredging installation holes 11, the interior of the dredging installation holes 11 can be shaped by the guide cone sleeves 39. Furthermore, the presence of the guide cone sleeves 39 facilitates rapid handling of the precast concrete components, improving handling convenience and, relatively, increasing throwing efficiency. The method of opening the dredging installation holes 11 allows some silt to flow through the dredging installation holes 11 to various sides of the reinforced concrete block 10, expanding the accumulation range of silt around the reinforced concrete block 10.

[0046] Each of the four unblocking installation holes 11 has a fixed bottom ring 32 fixedly connected to the side of the equilateral triangle face of the reinforced concrete block 10. Each set of fixed bottom rings 32 and impact top rings 31 is fixedly connected to an unblocking spring 33 and an isolation sealing sleeve 34, with the isolation sealing sleeve 34 located inside the unblocking spring 33.

[0047] Each of the four fixed bottom rings 32 has a connecting shaft 35 slidably connected to it. Each of the four impact top rings 31 has a connecting shaft 35 fixedly connected to its lower end face. All four connecting shafts 35 are located between the isolation sealing sleeve 34 and the unblocking spring 33. Each connecting shaft 35 has a unblocking pusher 36 fixedly connected to its lower end face. Each unblocking pusher 36 mates with the inner wall of the guide cone sleeve 39 at the same position. Each of the four connecting shafts 35 slides axially within an unblocking mounting hole 11. The diameters of the four connecting shafts 35 are much smaller than the diameter of the unblocking installation holes 11. The four connecting shafts 35 do not contact each other at their intersection points within the four unblocking installation holes 11. When the reinforced concrete block 10 is impacted by water flow, some water will enter the unblocking installation holes 11. At this time, the water flow impacts the top ring 31 and compresses the unblocking spring 33, causing the connecting shafts 35 to slide downward within the fixed bottom ring 32. Simultaneously, it causes the unblocking pusher 36 to contact the guide cone within the unblocking installation hole 11. The sliding of the sleeve 39 wall loosens the sludge deposited in the dredging installation hole 11 after being deposited by the structural components, preventing blockage. The accumulated sludge is then discharged from the tetrahedral structure to the outside of the guide cone sleeve 39 facing the three lower vertices, thus collecting and accumulating the accumulated sludge from top to bottom. This improves the efficiency of the silt-promoting structure and enhances the enrichment effect and quality of the sludge at the bottom of the anti-erosion and silt-promoting structure. In addition, the impact of water flow on the top ring 31 and the compression of the dredging spring 33 towards the fixed bottom ring 32, which drives the connecting shaft 35 to slide downward within the fixed bottom ring 32, also relatively promotes the flow velocity of the discharged water. This helps to expand the movement path of the sludge when it is discharged to the outside of the guide cone sleeve 39 facing the three lower vertices. This method allows sludge to accumulate over a larger distance around the reinforced concrete block 10, increasing the amount and range of sludge and sediment accumulation around the reinforced concrete block 10.

[0048] Example 3

[0049] Referring to Figure 9, the figure shows an experimental schematic of the effect of flow velocity and water level changes during different tidal surge periods on erosion prevention and siltation promotion. When the flexible erosion prevention and siltation promotion structure is deployed on a large scale on the shore, land-based equipment such as excavators and trucks can be used to assist in deployment to improve efficiency. When the deployment point for the water area to be protected is located in the middle of the river, it is necessary to use a boat for assisted deployment. The overall weight of the structural components is relatively large, and the draft of the transport vessel is relatively deep. In many cases, it is necessary to operate with the tide and deploy when the water level is close to high. At this time, the water flow velocity is low and the water depth is large, which is suitable for deployment.
