Description

Technical Field

[0001] This invention relates to the field of marine engineering technology, specifically to a bottom-mounted wave-damping structure and its installation method. Background Technology

[0002] Existing marine protective structures are mainly classified into bottom-mounted wave-dissipating structures, cut-off wave-dissipating structures, and floating wave-dissipating structures. Bottom-mounted wave-dissipating structures are the traditional type of breakwater, typically built directly on the seabed and constructed of rock, concrete, or other materials. They impede the impact of waves on the coastline by isolating the water body, eliminating the impact of waves throughout their entire cycle. Cut-off wave-dissipating structures refer to breakwaters composed of piers and wave-blocking structures submerged to a certain depth in the water. Through their permeability, they allow some wave energy to pass through the structure while simultaneously reflecting the waves, thus reducing the direct impact of wave energy. However, they are less effective at dissipating medium- and long-period waves. Floating wave-dissipating structures consist of wave-dissipating floats and mooring equipment. The wave-dissipating floats can be jars or rafts with a certain draft. This structure uses a floating body to prevent wave propagation or break waves, and interferes with the movement of water particles in the waves by floating up and down and swaying back and forth under the action of waves, thereby destroying the internal water flow structure of the waves and achieving the purpose of reducing wave energy. However, floating wave-dissipating structures are not effective for dissipating long-period waves and are also not suitable for storm surges with low-frequency long waves.

[0003] While bottom-mounted wave-damping structures are simple in design, they are generally bulky, unsuitable for deep waters, costly, difficult to construct, and cannot be disassembled and reused, limiting their application. To address these shortcomings, a prior art technology, titled "A Floating Bottom-Mounted Breakwater," proposes a breakwater structure comprising one or more detachably connected wave-damping modules. Each module includes a floating foundation and a wave-damping structure fixedly connected to the upper part of the floating foundation. The floating foundation can float on water or sink to the bottom. This breakwater structure is simple and easy to install. However, its wave-damping effect is limited, it cannot be used in deep water, its positioning is poor, it is greatly affected by wind and waves, and its positioning is unstable.

[0026] The advantages of this application are: 1. The wave-dissipating structure of this application includes a wave-dissipating chamber module and a guide pile module. The wave-dissipating chamber module is a columnar structure with an inlet hole on one side. This structure can introduce external waves into the interior of the wave-dissipating chamber module, so that the waves will resonate in the hollow cavity of the wave-dissipating chamber module, thereby realizing the reduction of strong swells and medium-to-long-period waves. The wave-dissipating chamber module is suspended in the sea through the guide pile module to form a bottom-sitting wave-dissipating structure.

[0028] 3. The inner side of the wave-damping chamber module of this application has an arc-shaped structure. After the waves enter the inner side of the wave-damping chamber module, they collide with the inner wall of the wave-damping chamber module more regularly, making it easier for Helmholtz resonance to occur, resulting in a better wave-damping effect.

[0029] 4. The wave-dissipating chamber module of this application is a hollow columnar structure with openings at the top and bottom. On the one hand, this structure is simple and easy to install and disassemble. On the other hand, this structure facilitates the dissipation of waves entering the interior.

The prefabricated units on both sides can be quickly assembled by inserting the boss into the corresponding limiting groove. The connection structure is very simple. Moreover, the combination structure of the boss and the limiting groove has a positioning function, which greatly facilitates assembly and disassembly.

[0033] 8.

[0035] 10. The guide pile module of this application restricts the horizontal movement of the prefabricated unit by using guide piles and restricts the descent of the prefabricated unit by using pile clamps, so that the wave damping chamber module can be stably suspended in the sea at the designed construction position. It has a simple structure, is easy to operate and use, and is extremely easy to install and disassemble.

[0036] 11. This application also relates to an installation method. The installation method of this application is used to install wave-damping structures and has extremely high construction efficiency. The overall height of the structure can be adjusted according to the water depth of the working area to meet the wave-damping design requirements.

[0037] 12. The wave-damping chamber module of this application is very easy to assemble.

[0038] 13. The assembly operation of the guide pile in this application is very simple.

[0039] 14. This application uses a pile clamp to limit the position of the wave-damping chamber module by installing a pile clamp on the guide pile and placing the wave-damping chamber module on the pile clamp. The installation method is very simple and also facilitates subsequent disassembly.

[0046] The embodiments of this application are described in detail below, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0048] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0049] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0050] This application relates to a bottom-mounted wave-dissipating structure. The wave-dissipating structure of this application is fixed in the sea and adopts a wave-dissipating structure that allows waves to diffract into the wave-dissipating chamber on the back side for resonance dissipation. The wave-dissipating structure of this application adopts a modular structure, which can select an appropriate number of prefabricated units for assembly according to needs. These assembled prefabricated units can be disassembled and put into use in the next location. Reuse reduces the overall cost and is suitable for widespread application. At the same time, this application uses a special guide pile module for fixation, and the entire wave-dissipating chamber can be stably confined in the sea in a good "floating" state. The construction efficiency of the entire wave-dissipating structure is extremely high.

[0051] Specifically, such as Figures 1-4 As shown, a bottom-mounted wave-dissipating structure includes a wave-dissipating chamber module and a guide pile module. The wave-dissipating chamber module is a hollow columnar structure anchored in the sea. The wave-dissipating chamber module has an inflow hole on its back side to introduce waves into the interior of the wave-dissipating chamber module. The inflow hole facilitates the inflow of waves from the outside of the wave-dissipating chamber module to the inside of the wave-dissipating chamber. The waves entering the wave-dissipating chamber will undergo Helmholtz resonance, and the waves cancel each other out, producing a good wave-dissipating effect. The wave-dissipating chamber module of this application is a modular assembly structure. The wave-dissipating chamber module includes multiple sets of prefabricated modules, which are stacked and fixedly connected in a vertical direction to form a whole. The prefabricated modules are manufactured in the factory and then transported to the construction site for assembly to form the required wave-dissipating chamber module. The production and processing are extremely convenient, and the assembly and construction are also extremely simple. More importantly, after the entire wave-dissipating structure is dismantled, the wave-dissipating chamber module can be disassembled into multiple prefabricated modules for easy reuse in the future.

[0052] The guide pile module fixes the wave-dissipating chamber module in the sea through a vertical pile foundation structure. The guide pile module is used to restrict the wave-dissipating chamber module in the water, so that the entire wave-dissipating chamber module is in a "floating" state. The guide pile module limits the position of the wave-dissipating chamber module through the vertical pile foundation. The structure is stable, easy to operate, and extremely easy to dismantle later.

[0053] During actual installation, the prefabricated wave-damping chamber modules and guide pile modules are transported to the construction site; multiple sets of prefabricated modules are assembled to form wave-damping chamber modules, and the wave-damping chamber modules are lowered to a preset height in the sea; the guide pile modules are fixed to the seabed of the construction area based on the erected stabilizing platform; the guide pile modules and wave-damping chamber modules are fixed; and the installation of the bottom-mounted wave-damping structure is completed.

[0054] In some embodiments of this application, the wave-damping chamber module described above is further optimized, such as... Figure 1 As shown, in this embodiment, the inflow hole penetrates the wave-dissipating chamber module from bottom to top, making the wave-dissipating chamber module open on the back side. That is, the wave-dissipating chamber module in this embodiment is a columnar structure with one side completely open. After the waves pass through the wave-dissipating chamber module, they will diffract and flow into the interior of the wave-dissipating chamber module from the open side, and Helmholtz resonance will occur inside the wave-dissipating chamber module to achieve the wave-dissipating effect.

[0055] To further enhance the wave-damping effect, the wave-damping chamber module in this embodiment is a hollow columnar structure with an arc-shaped inner wall. The arc-shaped inner wall allows for better wave resonance inside the wave-damping chamber module, reducing collisions with the inner wall and achieving wave damping primarily through Helmholtz resonance.

[0056] Furthermore, the wave-damping chamber module in this embodiment is a hollow cylindrical structure with openings at both the top and bottom. Waves entering the wave-damping chamber module will surge vertically up and down inside the module. Since the top and bottom of the wave-damping chamber module are open, the flow or surging of water inside the module is not restricted, further enhancing the wave-damping effect.

[0057] In a further embodiment of this application, the prefabricated module described above has been optimized, specifically, as follows: Figures 1-4 As shown, the wave-damping chamber module of this embodiment includes a multi-layer prefabricated module. The multi-layer prefabricated modules are stacked and fixed in sequence along the vertical direction to form the wave-damping chamber module of this application. Each prefabricated module includes multiple prefabricated units 1. The multiple prefabricated units 1 are spliced ​​and connected in sequence along the circumferential direction to form a columnar structure with an opening on the back wave side. The prefabricated unit 1 is an arc-shaped plate structure with connecting structures on both sides of the circumference and both sides of the axial direction.

[0058] Each prefabricated unit 1 is a uniformly sized arc-shaped plate structure, and each is a column-shaped component with an opening on one side. Once the specifications of the wave-damping chamber module are determined, an appropriate number of prefabricated units 1 can be selected for assembly to form the required wave-damping chamber module.

[0059] In the actual assembly of the wave-damping chamber module, multiple prefabricated units 1 are joined together circumferentially to form a single prefabricated module, and multiple layers of prefabricated single modules are joined together axially to form the required wave-damping chamber module. The entire assembly process is extremely simple and convenient to operate, enabling rapid prototyping of the required wave-damping chamber module.

[0060] Of course, in practical applications, it is not limited to the above assembly method. Alternatively, multiple prefabricated units 1 can be connected together vertically, and then multiple sets of sub-units 1 can be assembled together circumferentially to form the required wave-damping chamber module.

[0061] The subsequent dismantling is also very convenient. After the wave-damping chamber module is removed from the water, it is first disassembled into multiple prefabricated modules, and then the prefabricated modules are further disassembled into multiple prefabricated units 1.

[0062] In a preferred embodiment of this application, the structure of the prefabricated unit 1 described above has been optimized, specifically, as follows: Figure 3 and 4 As shown, in this embodiment, a connecting plate 3 with screw holes is provided on one side of the prefabricated unit 1 in the circumferential direction. The connecting plate 3 of the adjacent prefabricated unit 1 overlaps the circumferential side of another prefabricated unit 1 and the two prefabricated units 1 are connected into one piece by through bolts.

[0063] The connecting plate 3 is a structure that facilitates connecting adjacent prefabricated units 1 in the circumferential direction into one unit. The connecting plate 3 extends radially towards the inside of the prefabricated unit 1 and forms an L-shaped structure with the body of the prefabricated unit 1. That is, when the connecting plate 3 overlaps the circumferential side of another prefabricated unit 1, the ends of the two prefabricated units 1 are abutted together, and the connecting plate 3 is located radially inside the abutting position.

[0064] The connecting plate 3 has multiple screw holes evenly spaced along the axial direction, and the other side of the prefabricated unit 1 has multiple corresponding screw holes evenly spaced along the axial direction. When two prefabricated units 1 need to be assembled together, simply overlap the connecting plate 3 of one prefabricated unit 1 onto the circumferential side of the other prefabricated unit 1, aligning the screw holes at the overlap in the radial direction, then drive bolts into the aligned screw holes and tighten the bolts to fix the two adjacent prefabricated units 1 together. By connecting multiple prefabricated units 1 in sequence, the required prefabricated module can be formed.

[0065] Furthermore, this embodiment optimizes the interlayer connection structure of the prefabricated unit 1 described above, specifically, as follows: Figure 3 and4 As shown, multiple sets of interlayer fixing structures are arranged circumferentially on the outer side of the prefabricated unit 1. The interlayer fixing structure includes two fixing seats 4 arranged vertically. One fixing seat 4 in the same set has a vertically protruding boss 5 on one side relative to the other fixing seat 4. The other fixing seat 4 has a limiting groove 6 on one side relative to the boss 5. The axially adjacent prefabricated units 1 are fixed together by being engaged in the limiting groove 6 through the boss 5.

[0066] In this embodiment, the boss 5 can be a protrusion structure disposed on the upper fixing seat 4 of the same group, or it can be a protrusion structure disposed on the lower fixing seat 4 of the same group, as long as it meets the corresponding connection function. For example Figure 3 and 4 As shown, the boss 5 in this embodiment is a protruding structure provided on the lower fixing seat 4 of the same group, and the upper fixing seat 4 of the same group is provided with a limiting groove 6. Two sets of interlayer fixing structures are provided on the outer circumference of each prefabricated unit 1, and the two sets of interlayer fixing structures are respectively placed on the prefabricated unit 1 near its circumferential side.

[0067] The boss 5 is a protruding columnar structure that extends out of the corresponding prefabricated unit 1 in the axial direction. That is to say, when two axially adjacent prefabricated units 1 are assembled together, the intersection line of the boss 5 and the two prefabricated units 1 overlaps in the horizontal direction.

[0068] When it is necessary to fix two axially adjacent prefabricated units 1 together as one unit, the boss 5 of one prefabricated unit 1 in the axial direction is inserted into the limiting groove 6 of the other prefabricated unit 1, so that the two axially adjacent prefabricated units 1 are assembled together in the axial direction.

[0069] In order to make the connection between two axially adjacent prefabricated units 1 more compact, this embodiment provides a first through hole 7 that penetrates the boss 5 along the tangential direction, and a second through hole 8 that penetrates the fixing seat 4 and the limiting groove 6 along the tangential direction is provided on the fixing seat 4. After the boss 5 is inserted into the limiting groove 6, it is fixedly connected to the limiting groove 6 by bolts that pass through the first through hole 7 and the second through hole 8.

[0070] In other words, when the boss 5 is inserted into the corresponding limiting groove 6, the first through hole 7 on the boss 5 and the second through hole 8 on the corresponding fixing seat 4 of the limiting groove 6 are aligned in the horizontal direction. By driving bolts into the aligned first through hole 7 and second through hole 8 and tightening the bolts, the fixing seat 4 corresponding to the boss 5 and the fixing seat 4 corresponding to the corresponding limiting groove 6 are fixedly connected as one unit, and the two prefabricated units 1 can be assembled together tightly and firmly.

[0071] In other embodiments of this application, the above-described guide pile module has been optimized, specifically, as follows: Figure 1As shown, the guide pile module of this application includes a guide pile 2 and a pile clamp 11 fixed on the guide pile 2 and located below the guide seat 9 to restrict the downward movement of the wave-damping chamber module. The guide pile 2 of this application is a pipe pile structure driven into the seabed. The upper end of the guide pile 2 is provided with a lifting lug structure for easy hoisting. The pile clamp 11 is a clamp-type structure that is fitted onto the guide pile 2, and then the bolts are tightened to fix it on the guide pile 2.

[0072] The outer side of prefabricated unit 1 has a guide seat 9 corresponding to prefabricated unit 1, such as... Figures 1-4 As shown, a plurality of guide seats 9 are provided on the outer circumference of the prefabricated unit 1. Guide holes 10 are provided on the guide seats 9 for the prefabricated unit 1 to pass through. The guide holes 10 in the guide seats 9 of the axially adjacent prefabricated units 1 are aligned vertically.

[0073] After the prefabricated unit 1 is assembled into the wave-damping chamber module, the guide holes 10 on all the guide seats 9 in the same axial direction are aligned. The guide pile 2 can be easily inserted into the aligned guide holes 10 to complete the connection between the guide pile 2 and the sub-unit 1. The guide pile 2 restricts the non-vertical movement of the sub-unit 1. The pile clamp is located below the guide seat 9, which allows the prefabricated unit 1 to rest on the pile clamp, completing the arrangement of the wave-damping chamber module.

[0074] The bottom-mounted wave-damping structure of this application shall be installed according to the following steps:

[0075] S1. The required pile stabilizing platform, prefabricated unit 1, guide pile 2 and pile clamping device are prefabricated in the factory and transported to the construction site by transport ships; except for the four auxiliary piles, the other structures of the pile stabilizing platform have been assembled on the shore.

[0076] S2. Assemble the wave-damping chamber module. Overlap the connecting plate 3 of one prefabricated unit 1 onto the circumferential side of another prefabricated unit 1, aligning the screw holes at the overlap in the radial direction. Then, drive bolts into the aligned screw holes and tighten them to fix the two adjacent prefabricated units 1 into one unit. Assemble multiple prefabricated units 1 in sequence to form the required prefabricated module. Connect the two adjacent layers of prefabricated modules together. Insert the boss 5 of one prefabricated unit 1 into the limiting groove 6 of another axially adjacent prefabricated unit 1, aligning the first through hole 7 and the second through hole 8. Then, drive bolts into the first through hole 7 and the second through hole 8 to fix the two axially adjacent prefabricated units 1 into one unit. Connect them in sequence until the two axially adjacent prefabricated modules on both sides are fixed together. Complete the docking operation of the remaining prefabricated modules in sequence until the required wave-damping chamber module is formed.

[0077] S3. Release the fixing device between the adjustable pile platform and the transport vessel, and the lifting equipment of the transport vessel will use slings to fix the pile platform to the seabed.

[0078] S4. Use a crane to connect the lifting lugs on the top of the assembled wave-damping chamber module with slings to suspend it above the corresponding construction sea surface and keep it in the suspended state;

[0079] S5. Using the main crane on the stabilizing platform, the precast guide pile 2 is lifted and erected by connecting the lifting lugs on the top of the guide pile 2 with the slings. After the pile is erected, the pile clamp is adjusted, and the guide pile 2 is fed into the pile clamp by adjusting the ship position. The guide pile 2 is clamped by the pile clamp, and the verticality of the guide pile 2 is observed. When there is a large deviation in the verticality of the guide pile 2, the verticality of the guide pile 2 is adjusted by the hydraulic cylinder jacks, so that the guide pile 2 sinks through the guide hole 10 on the precast unit 1. According to the water depth data, the pile clamp is installed at the corresponding position of the guide pile 2 through the passage by bolts.

[0080] S6. Remove the pile stabilizing platform and install the pile stabilizing platform at the construction point of the next guide pile 2. Continue in this manner until all guide piles 2 are completed.

The main body of the pile stabilizing platform includes a bottom section structure, a transition section structure, a working platform section structure, and auxiliary piles. The height of the pile stabilizing platform can be controlled by adjusting the number of layers in the spliced ​​intermediate section structure, thereby adapting to different water depth requirements. The working platform structure is equipped with lifting lugs on its upper part, and the platform deck can be used to store some pile driving construction tools, pile clamping devices, and other equipment, greatly facilitating construction. All structural components are connected by high-strength bolts.
