Description

Technical Field

[0001] The invention relates to the technical field of marine engineering, and in particular to an assembled wave-breaking structure and an installation method thereof. Background Art

[0002] Long-period waves in deep sea have a great impact on the safety and service life of structures in the construction of marine engineering and the operation and maintenance of marine structures, but there is no good wave-breaking structure for long-period waves in deep sea. Wave-breaking technology for strong surges and long-period waves in deep sea environment has become a key common technical problem that needs to be solved urgently in port engineering construction.

[0003] The existing marine structure protection structures are mainly divided into bottom-seated wave-breaking structures, truncated wave-breaking structures and floating wave-breaking structures. The traditional bottom-seated protection structure blocks the propagation of waves by blocking the water body. The embankment body extends uniformly from the water surface to the seabed, including vertical breakwaters, composite breakwaters and riprap slope embankments. The truncated protection structure uses the principle that wave energy is mainly concentrated on the surface. It is composed of piers and wave-blocking structures submerged in the water to a certain depth. The upper wave-blocking structure can adopt a box type or a baffle type, and the lower support structure can adopt a column type, a pier type or a frame type. The bottom-seated protection structure can eliminate waves of the entire cycle. The truncated protection structure has good wave-breaking effect and is economical. However, if it is applied to a deep-sea environment, if a bottom-seated wave-breaking structure is used in a deep-sea environment, the structure size will be very large, the construction cost will be high, the construction will be difficult, and the structural form will not be applicable; the truncated wave-breaking structure can adapt to a deeper water environment, but has a poor wave-breaking effect on strong surges and medium and long period waves, and has poor structural stability in a deep-water environment.

[0004] The floating protective structure uses a floating body to interfere with the movement of water particles in the wave, prevent the wave from propagating or break the wave, and is composed of a wave-breaking float and a mooring system. For example, the prior art entitled A floating breakwater structure with a wave-breaking chamber and a wave-breaking board and its construction method introduces a floating breakwater structure, which includes a pontoon part, an anchoring system part, and a connecting part. The pontoon part is positioned on the sea surface through the anchoring system part. Each pontoon part is arranged in sequence, and adjacent pontoon parts are connected to each other through the connecting part. Wave-breaking chambers are respectively arranged on the side close to the wave-facing side and the side close to the wave-repelling side of the pontoon part, and a floating chamber is arranged in the middle of the pontoon part. The structure is composed of a series of standard pontoon parts, and wave-breaking chambers are arranged on the wave-facing side and the wave-repelling side of the pontoon part, which can effectively dissipate the incident wave energy, reduce the transmitted waves, and reduce the radiation waves generated by the oscillation of the pontoon part, and has an excellent wave-breaking effect. However, this structure also has some problems. The breakwater of this structure is only effective against short-period waves within 3 to 5 seconds, and has poor wave-breaking effect on strong surges and long-period waves, and cannot provide effective protection for marine structures.

In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0053] The present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0054] The present application relates to a modular wave-breaking structure, which floats on the sea surface when in use. The wave-breaking structure is provided with an inflow hole on the back wave side. After the waves pass through the wave-breaking structure, they will flow into the wave-breaking structure from the inflow hole on the back wave side, and Helmholtz resonance will occur inside the wave-breaking structure, thereby obtaining a good wave-breaking effect. Moreover, when the wave-breaking structures of the present application are arranged in an array pattern, the waves passing through the first row of wave-breaking structures will be reflected by the second row of wave-breaking structures, and the reflected waves will enter the first row of wave-breaking structures from the inflow hole of the first row of wave-breaking structures, and Helmholtz resonance will continue to occur, further improving the wave-breaking effect. The wave-breaking structure of the present application is a modular structure, which can be assembled according to actual needs. The overall assembly, installation and disassembly are very convenient. The disassembled wave-breaking structure can be reused, reducing the cost of use.

[0055] In some embodiments of the present application, the present embodiment optimizes the assembled wave-breaking structure, specifically, Figures 1 to 7 As shown, an assembled wave-breaking structure of the present embodiment includes a pontoon structure and a floating body structure. The pontoon structure is a plate-like structure formed by splicing a plurality of pontoon units 1 with buoyancy adjustment function. The pontoon structure is the base part of the entire wave-breaking structure. The pontoon unit 1 has the function of buoyancy adjustment. By adjusting the buoyancy of the pontoon unit 1, the buoyancy of the entire wave-breaking structure can be adjusted, thereby changing the floating state of the entire wave-breaking structure to meet different wave-breaking requirements.

[0056] The floating structure is a hollow columnar structure with an inflow hole on the back side formed by splicing multiple floating modules. The floating structure is fixed on the pontoon structure to form a columnar wave-breaking chamber floating on the water surface. The floating structure is the main part of the entire wave-breaking structure and constitutes the wave-breaking chamber of the wave-breaking structure. Waves flow into the floating structure from the inflow hole on the floating structure, and Helmholtz resonance occurs in the hollow floating structure, achieving a good wave-breaking effect.

[0057] Furthermore, this embodiment optimizes the above-mentioned floating structure, such as Figure 1 As shown, the floating structure of this embodiment includes multiple floating modules, which are spliced ​​in sequence along the vertical direction. The floating module includes multiple floating units 2, and the multiple floating units 2 are spliced ​​in sequence along the circumferential direction to form a columnar floating module with an opening on the back wave side.

[0058] like Figure 1 As shown, the inflow hole penetrates the floating structure from bottom to top, so that the wave-repelling side of the floating structure is an open structure. The inner wall of the floating structure is an arc-shaped hollow columnar structure.

[0059] The floating structure is a hollow columnar structure formed by splicing multiple layers of floating modules in sequence. The single-layer floating module is a columnar structure with an opening on one side. The open side of the floating module is the inflow hole. Multiple layers of floating modules are stacked in sequence to form the required floating structure. Therefore, from the overall structure point of view, the floating structure is a hollow columnar structure with an opening on the side, and the top view of the floating structure is a C-shaped structure.

[0060] The inner side of the floating structure is an arc-shaped structure, such as Figure 1 and 4 As shown, the inner side of the floating structure of this embodiment is a cylindrical structure. Designing the inner side of the floating structure as an arc structure can enhance the effect of Helmholtz resonance and the effect of wave elimination. In actual application, the shape of the internal structure of the floating structure is not limited, as long as it can meet the wave elimination effect. The cylindrical structure inside the floating structure is an optimized solution.

[0061] Furthermore, this embodiment optimizes the structure of the floating unit 2, such as Figures 4 to 6 As shown, the floating unit 2 of this embodiment includes a steel frame 21 and a floating block 22 filled in the steel frame 21. The steel frame 21 is the skeleton structure of the floating unit 2, and the floating block 22 is made of polyethylene to provide buoyancy for the entire floating unit 2. The steel frame 21 can effectively improve the structural strength of the entire floating unit 2, and is arranged to be less damaged when dealing with harsh environments.

[0062] The connection between adjacent floating units 2 is mainly achieved through steel frames 21, such as Figure 6 As shown, the steel frame 21 is provided with a plurality of side screw holes 211 on both sides of the circumference, and the adjacent floating units 2 in the floating module are connected as a whole through the side screw holes 211. The steel frame 21 is provided with a plurality of vertical screw holes 212 on both sides of the axial direction, and two axially adjacent floating units 2 are connected as a whole through the vertical screw holes 212.

[0063] When it is necessary to connect two circumferentially adjacent floating units 2, the two floating units 2 are butted together in the circumferential direction, so that the side screw holes 211 of the circumferential side of the floating unit 2 are aligned with each other, and then bolts are driven into the aligned side screw holes 211, and the bolts are tightened to fix the two adjacent floating units 2 together. When it is necessary to connect two axially adjacent floating units 2, the two floating units 2 are butted together in the axial direction, so that the vertical screw holes 212 of the axial side of the floating unit 2 are aligned with each other, and then bolts are driven into the aligned vertical screw holes 212, and the bolts are tightened to fix the two axially adjacent floating units 2 together. This bolt connection structure is not only convenient to connect, but also very convenient to disassemble.

[0064] In order to further facilitate the docking of axially adjacent floating units 2, as Figure 4 and 5As shown, the floating block 22 of this embodiment is provided with a first protrusion 221 protruding along the axial direction at one end thereof, and a first recess 222 recessed along the axial direction at the other end thereof. The first protrusions 221 of two axially adjacent floating units 2 are engaged in the first recess 222 to limit the non-vertical displacement of the two floating units 2.

[0065] The first protrusion 221 can be located at the top of the floating unit 2 or at the bottom of the floating unit 2, as long as the actual assembly requirements are met. Figure 4 and 5 As shown, this embodiment indicates that the first protrusion 221 is located at the top of the floating unit 2 , and the first recess 222 is located at the bottom of the floating unit 2 .

[0066] The first protrusion 221 is an arc-shaped strip structure protruding along the axial direction, and the first concave 222 is an arc-shaped groove structure corresponding to the first protrusion 221. When the first protrusion 221 is engaged in the corresponding first concave 222, the non-vertical relative displacement of two axially adjacent floating units 2 can be limited. The first protrusion 221 and the first concave 222 have both positioning and fixing functions, which facilitates the assembly and disassembly of the floating unit 2.

[0067] When assembling the floating structure, two floating units 2 are butted together in the circumferential direction, so that the side screw holes 211 of the floating units 2 in the circumferential direction are aligned with each other, and then bolts are driven into the aligned side screw holes 211, and the bolts are tightened to fix the two adjacent floating units 2 together as a whole, and the floating units 2 of the floating modules of this layer are installed in sequence until the required floating modules are formed; the floating modules of the upper layer are assembled based on the floating modules that have been assembled, and the floating units 2 in the upper floating modules are connected with the adjacent floating modules in the next floating modules. The floating unit 2 is positioned and connected as a whole by engaging the first protrusion 221 into the first recess 222, and the two floating units 2 are butt-jointed in the axial direction so that the vertical screw holes 212 on the axial sides of the floating units 2 are aligned with each other. Then, bolts are driven into the aligned vertical screw holes 212 and tightened to fix the two axially adjacent floating units 2 as a whole. The above method is carried out in sequence until the assembly and connection of the next layer of floating modules is completed; the above method is carried out in sequence until the assembly of all floating modules is completed to form the desired floating structure.

[0068] In addition, as mentioned above, the floating structure of the present application is a columnar structure, and the structural strength of the columnar structure is relatively weak at the opening side. In order to improve the strength of the entire floating structure, the present embodiment provides a support frame 3 in the inflow hole of the floating structure to improve the strength of the entire floating structure. The support frame 3 is arranged at the opening position of the floating structure to horizontally support the floating structure, which can effectively improve the stability and strength of the entire floating structure.

[0069] Specifically, Figure 1 and 4 As shown, the support frame 3 is arranged at the opening position of the floating module, and the two circumferential ends of the support frame 3 are respectively supported at the ends of the opening position of the floating module. In actual use, the structure of the support frame 3 of this embodiment is the same as the steel frame 21, except that there is no floating block 22 on the support frame 3. Each layer of the floating module is correspondingly installed with a group of support frames 3. The position of the support frame 3 is the opening of the floating module. The support frame 3 and the floating module form a complete annular structure, which greatly improves the structural strength of the entire floating module. The support frame 3 is a frame structure, which itself will not have a significant impact on the entry of waves into the buoyancy structure.

[0070] Of course, the structure of the support frame 3 is not limited to the above-mentioned form similar to the steel frame 21 structure, and other structures can also be used as long as the floating module can be strengthened without causing excessive impact on the wave inrush into the floating structure.

[0071] Similarly, the support frame 3 is provided with corresponding screw hole structures on both sides of the circumferential direction and the axial direction. The support frame 3 is fixedly connected to the adjacent floating unit 2 by docking with the side screw holes 211 on the steel frame 21 in the adjacent floating unit 2 of the same layer through the screw holes on both sides of the circumferential direction. The support frame 3 is fixedly connected to the adjacent support frames 3 on both sides by docking with the screw holes on the axially adjacent support frames 3 through the screw holes on both sides of the axial direction. The support frame 3 is assembled and formed together with the floating unit of the same layer, and the floating structure finally formed is a complete columnar structure.

[0072] Furthermore, this embodiment optimizes the above-mentioned buoyancy tank structure, such as Figure 1 and 2 As shown, a through hole is provided at the center of the buoyancy structure to connect the inner and outer spaces of the floating structure. That is, seawater can enter the floating structure through the through hole, and the seawater in the floating structure can also be discharged through the through hole. The upper end of the floating structure is completely open. This structure can make the water flow in the floating structure smoother and improve the effect of wave elimination.

[0073] Furthermore, the pontoon unit 1 of this embodiment is a fan-shaped plate-like structure, and the pontoon unit 1 is fixedly connected to the adjacent pontoon unit 1 through a first connection structure on its circumferential side, and is fixedly connected to the floating structure through a second connection structure on the axial top surface.

[0074] like Figure 2 and 3As shown, the first connection structure includes a plurality of first screw holes 11 provided on both sides of the circumferential direction of the pontoon unit 1, and adjacent pontoon units 1 are fixedly connected as a whole through the first screw holes 11. When adjacent pontoon units 1 are connected, the adjacent pontoon units 1 are butt-jointed together in the circumferential direction, the first screw holes 11 of the adjacent pontoon units 1 are accurately aligned, bolts are driven into the aligned first screw holes 11, the bolts are tightened, and the adjacent pontoon units 1 are fixedly connected as a whole, and are connected in sequence until a disc-shaped pontoon structure is formed.

[0075] In addition, in order to facilitate the docking of adjacent pontoon units 1, the first connection structure of the present embodiment also includes a second protrusion 12 and a second recess 13 arranged on the circumferential side of the pontoon unit 1. The second protrusion 12 is a strip-shaped structure protruding along the circumferential direction, and the second recess 13 is a groove-shaped structure corresponding to the circumferential recess of the second protrusion 12. The second protrusion 12 is engaged in the second recess 13 to limit the non-circumferential movement of the adjacent pontoon units 1.

[0076] When it is necessary to assemble adjacent pontoon units 1, the second protrusion 12 on the circumferential side of one pontoon unit 1 can be inserted into the second recess 13 on the circumferential side of the adjacent pontoon unit 1 along the circumferential direction to position and connect the two adjacent pontoon units 1. The second protrusion 12 and the second recess 13 can not only effectively limit the relative displacement of the adjacent pontoon units 1 in the non-circumferential direction, but also play a role in positioning and assembling, so that the two pontoon units 1 can be stably docked together.

[0077] This embodiment also optimizes the arrangement structure of the second protrusion 12 and the second recess 13. Specifically, Figure 3 As shown, each side of the pontoon unit 1 of this embodiment is provided with at least one second protrusion 12 and at least one second recess 13 in the circumferential direction, and the second protrusions 12 and the second recesses 13 in the circumferential side of the pontoon unit 1 are arranged alternately. Figure 3 As shown, a second protrusion 12 and a second recess 13 are provided on each circumferential side of the pontoon unit 1 of this embodiment, and the second protrusion 12 is located radially inside the second recess 13. There is also a second protrusion 12 and a second recess 13 on the other circumferential side of the pontoon unit 1, but the second protrusion 12 on this side is located radially outside the second recess 13. Such a structure can connect adjacent pontoon units 1 in a mutually interlocking manner, which can prevent the adjacent pontoon units 1 from generating relative displacement in the radial direction, and further improve the stability of the connection structure of the adjacent pontoon units 1.

[0078] The second connection structure of this embodiment is a structure for connecting the buoyancy unit 1 with the floating body unit 2. Figure 3As shown, the second connection structure includes a third protrusion 14 or a third recess 15 (not shown in the figure) arranged on the top surface of the pontoon unit 1, and the pontoon unit 1 is connected to the bottom pontoon module by the third protrusion 14 being engaged with the first recess 222 at the lower end of the bottom pontoon module, or by the first protrusion 221 at the lower end of the bottom pontoon module being engaged in the third recess 15. That is, if the bottom surface of the pontoon unit 2 is provided with the first recess 222, then the top surface of the pontoon unit 1 is provided with the third protrusion 14; conversely, if the bottom surface of the pontoon unit 2 is provided with the first protrusion 221, then the top surface of the pontoon unit 1 is provided with the third recess 15. This embodiment Figure 2 and 3 The structure shown in FIG. 1 is the third protrusion 14 .

[0079] Whether it is the combined structure of the third protrusion 14 and the first recess 222 or the combined structure of the first protrusion 221 and the third recess 15, both are for the convenience of assembling the float unit 2 onto the pontoon unit 1. When assembling the float unit 2 onto the pontoon unit 1, align the first recess 222 on the bottom surface of the float unit 2 with the third protrusion 14 on the pontoon unit 1 so that the third protrusion 14 is snapped into the first recess 222, and the float unit 2 and the pontoon unit 1 are well positioned and assembled; or, align the first protrusion 221 on the bottom surface of the float unit 2 with the third recess 15 on the pontoon unit 1 so that the first protrusion 221 is snapped into the third recess 15, and the float unit 2 and the pontoon unit 1 are well positioned and assembled.

[0080] After completing the above positioning and assembly, it is still necessary to fully fix it, such as Figure 2 and 3 As shown, the second connection structure of this embodiment also includes a second screw hole 16 arranged on the radially outer side of the pontoon unit 1, and the pontoon unit 1 is fixedly connected to the floating structure by a bolt passing through the second screw hole 16. The second screw hole 16 of this embodiment corresponds to the vertical screw hole 212 on the above-mentioned steel frame 21. After the positioning and assembly of the pontoon unit 2 and the pontoon unit 1 are completed, the vertical screw hole 212 on the pontoon unit 2 is aligned one by one with the second screw hole 16 on the lower pontoon unit 1, and bolts are driven into the aligned vertical screw holes 212 and the second screw holes 16, and the bolts are tightened to fix the pontoon unit 1 and the pontoon unit 2 as a whole.

[0081] In addition, the radial outer side of the pontoon unit 1 of this embodiment is provided with an inlet pipe 17 and an outlet pipe 18, which are in communication with the internal space of the pontoon unit 1 and are disposed at positions close to both sides of the circumference of the pontoon unit 1. The inlet pipe 17 and the outlet pipe 18 are respectively connected to the external water injection structure and the pumping structure for adjusting the gravity of the pontoon unit 1. The inlet pipe 17 and the outlet pipe 18 are structures for adjusting the gravity of the pontoon unit 1. The pontoon unit 1 is a hollow structure. Changing the gravity of the pontoon unit 1 by using the inlet pipe 17 and the outlet pipe 18 is actually changing its density, so as to achieve the purpose of adjusting the buoyancy of the pontoon unit 1. Adjusting the buoyancy of the pontoon unit 1 can change the buoyancy of the entire wave-breaking structure and change the floating state of the wave-breaking structure on the sea surface.

[0082] In actual application, the water inlet pipe 17 on the radial outside of the pontoon unit 1 is connected to the water injection structure, and the water outlet pipe 18 on the radial outside of the pontoon unit 1 is connected to the water pumping structure. Water is injected into the water inlet pipe 17 through the water injection structure, and the water pumping structure pumps water into the water outlet pipe 18 to change the gravity of the pontoon unit 1, thereby adjusting the buoyancy of the pontoon structure.

[0083] In addition, in order to further improve the strength of the entire wave-breaking structure, a plurality of support columns 4 are provided on the wave-breaking structure. Figure 7 As shown, in this embodiment, a plurality of support columns 4 arranged at intervals along the circumferential direction are provided on the pontoon structure. The support columns 4 are tubular or rod-shaped structures arranged vertically. The lower ends of the support columns 4 are fixedly connected to the pontoon units 1. Specifically, a bottom plate is provided at the lower ends of the support columns 4. The bottom plate is a square flat plate structure, and a plurality of screw holes are provided on the bottom plate. An axially inwardly recessed mounting groove is provided at a position close to both sides of the circumference of the top surface of the pontoon unit 1, and corresponding screw holes are provided in the mounting groove. When two adjacent pontoon units 1 are assembled together, the two mounting grooves form a mounting structure corresponding to a bottom plate, and a part of the bottom plate is in the mounting groove of one pontoon unit 1, and the other part is in the mounting groove of the other pontoon unit 1. Bolts are then driven into the aligned screw holes, and the support columns 4 can be fixed at the junction of the adjacent pontoon units 1 by tightening the bolts.

[0084] The support column 4 is located between adjacent pontoon units 1, and also between circumferentially adjacent floating units 2. In order to facilitate the arrangement of the support column 4, the present embodiment provides an arc groove 23 on the circumferential side of the floating unit 2 to accommodate the passage of the support column 4. The arc groove 23 here is a groove structure on the circumferential side of the floating unit 2. The steel frame 21 and the floating block 22 are provided with corresponding groove structures. After the circumferentially adjacent floating units 2 are docked together, the two arc grooves 23 form a vertical through-hole structure. The adjacent through-hole structures in the axial direction are connected in sequence to form a vertical hole that passes through the floating structure along the axial direction, and the support column 4 is penetrated inside the vertical hole.

[0085] The support column 4 is the skeleton structure of the entire wave-breaking structure, which further improves the stability and strength of the entire wave-breaking structure.
