Description

Technical Field

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

[0002] Existing marine structure protection structures are mainly divided into bottom-seated wave-breaking structures, truncated wave-breaking structures and floating wave-breaking structures. Bottom-seated wave-breaking structures are traditional types of breakwaters, usually built directly on the seabed and made of rocks, concrete or other materials. They block the impact of waves on the coastline by blocking the water body and can eliminate the impact of full-cycle waves; truncated wave-breaking structures refer to breakwaters composed of piers and wave-blocking structures submerged in the water to a certain depth. Through its air-permeable characteristics, it allows part of the wave energy to pass through the structure and reflects the waves at the same time, thereby reducing the direct impact of the wave energy. The wave-breaking effect on medium and long-cycle waves is poor; floating wave-breaking structures are composed of wave-breaking buoys and anchoring equipment. The wave-breaking buoys can be boxes or floating rows with a certain draft depth. This structure uses floating bodies to prevent wave propagation or break waves, and interferes with the movement of water particles in the waves by floating up and down and swinging back and forth under the action of waves, destroying the water flow structure inside the waves to achieve the purpose of reducing wave energy. Floating wave-breaking structures have poor wave-breaking effects on long-period waves, and are also poorly applicable to low-frequency long-wave storm surges.

[0003] The bottom-seated wave-breaking structure has a simple structure, but is generally bulky, cannot adapt to deeper waters, has high costs, is difficult to construct, and cannot be disassembled and reused, resulting in a very limited scope of application. In order to solve the many defects of this traditional bottom-seated wave-breaking structure, a prior art called a floating bottom-seated breakwater proposes a breakwater structure, which includes one or more mutually detachably connected wave-breaking modules, each wave-breaking module includes a floating foundation and a wave-breaking structure fixedly connected to the upper part of the floating foundation, and the floating foundation can float in the water or sink to the bottom of the water. The breakwater has a simple structure and is easy to install. However, the breakwater structure has limited wave-breaking effect, and cannot be used in locations with greater water depths. The positioning effect of the breakwater is poor, it is greatly affected by wind and waves, and the positioning is unstable. Summary of the invention

[0035] 10. The pile guide module of the present application limits the horizontal movement of the prefabricated unit through the guide piles, and limits the descent of the prefabricated unit through the pile clamp, so that the wave-breaking chamber module can be stably suspended at the designed construction position in the sea. It has a simple structure, is easy to operate and use, and is extremely easy to install and disassemble;

[0036] 11. The present application also relates to an installation method.

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

[0048] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. 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.

[0049] The present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0050] The present application relates to a bottom-seat wave-breaking structure, which is fixed in the sea and adopts a wave-breaking structure in which the wave diffraction on the back side is allowed to enter the wave-breaking chamber for resonance dissipation. The wave-breaking structure of the present application adopts a modular structure, and a suitable number of prefabricated units can be selected for assembly according to needs. These assembled prefabricated units can be put into the next position for use after disassembly. The reuse reduces the overall construction cost and is suitable for promotion and application. At the same time, the present application adopts a special guide pile module for fixing, and the entire wave-breaking chamber can be stably confined in the sea in a good "suspended" state, and the construction efficiency of the entire wave-breaking structure is extremely high.

[0051] Specifically, Figures 1 to 4 As shown, a bottom-seated wave-breaking structure includes a wave-breaking chamber module and a guide pile module. The wave-breaking chamber module is a hollow columnar structure anchored in the sea. An inflow hole for introducing waves into the interior of the wave-breaking chamber module is arranged on the wave-dorsal side of the wave-breaking chamber module. The inflow hole facilitates waves to flow from the outside of the wave-breaking chamber module to the inside of the wave-breaking chamber. The waves flowing into the interior of the wave-breaking chamber will produce Helmholtz resonance, and the waves offset each other to produce a good wave-breaking effect. The wave-breaking chamber module of the present application is a modular assembly structure. The wave-breaking chamber module includes a plurality of groups of prefabricated modules, which are stacked and fixedly connected in sequence vertically as a whole. The prefabricated modules are manufactured in a factory and then transported to a construction site for assembly to form the required wave-breaking chamber modules. The production and processing are extremely convenient, and the assembly and construction also become extremely simple. More importantly, after the entire wave-breaking structure is dismantled, the wave-breaking chamber module can be disassembled into a plurality of prefabricated modules for subsequent reuse.

[0052] The guide pile module fixes the wave-breaking chamber module in the sea through a vertical pile foundation structure. The guide pile module is used to restrict the wave-breaking chamber module in the water, making the entire wave-breaking chamber module "suspended". The guide pile module limits the wave-breaking chamber module through a vertical pile foundation, with a stable structure, convenient operation, and extremely easy subsequent dismantling.

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

[0054] In some embodiments of the present application, the present embodiment further optimizes the above-mentioned wave-breaking chamber module, such as Figure 1 As shown, the inflow hole of the present embodiment penetrates the wave-breaking chamber module from bottom to top, so that the wave-removing side of the wave-breaking chamber module is an open structure, that is, the wave-breaking chamber module of the present embodiment is a columnar structure with one side completely open. After the waves pass through the wave-breaking chamber module, they will diffract and surge into the interior of the wave-breaking chamber module from the open side of the wave-breaking chamber module, and Helmholtz resonance will occur inside the wave-breaking chamber module to achieve the effect of wave elimination.

[0055] In order to further improve the wave-breaking effect, the wave-breaking chamber module of this embodiment is a hollow cylindrical structure with an arc-shaped inner wall. The arc-shaped inner wall can make the waves entering the wave-breaking chamber module resonate better, reduce the collision with the inner wall of the wave-breaking chamber module, and achieve the purpose of wave breaking more through Helmholtz resonance.

[0056] In addition, the wave-breaking chamber module of this embodiment is a hollow columnar structure with openings at both ends. Waves entering the wave-breaking chamber module will surge vertically up and down in the wave-breaking chamber module. The upper and lower ends of the wave-breaking chamber module are open, so the flow or surge of water inside the wave-breaking chamber module will not be restricted, further improving the effect of wave breaking.

[0057] In a further embodiment of the present application, the present embodiment optimizes the above-mentioned prefabricated modules. Specifically, Figures 1 to 4 As shown, the wave-breaking chamber module of the present embodiment includes multiple layers of prefabricated modules, which are stacked and fixed in sequence along the vertical direction to form the wave-breaking chamber module of the present application, and each prefabricated module includes multiple prefabricated units 1, which are spliced ​​and connected in sequence along the circumferential direction to form a columnar structure with an opening on the back-wave side, and the prefabricated unit 1 is an arc-shaped plate-like structure with connecting structures arranged on both sides of the circumference and the axial direction.

[0058] Each prefabricated unit 1 is a circular arc plate structure with uniform specifications, and is a columnar component with one side open. After the specifications of the wave-breaking chamber module are determined, a suitable number of prefabricated units 1 can be selected for assembly to form the required wave-breaking chamber module.

[0059] When assembling the wave-breaking chamber module, multiple prefabricated units 1 are connected together along the circumferential direction to form a layer of prefabricated modules, and multiple layers of prefabricated single modules are connected together along the axial direction to form the required wave-breaking chamber module. The entire assembly process is extremely simple and easy to operate, and the required wave-breaking chamber module can be quickly formed.

[0060] Of course, in actual application, it is not limited to the above-mentioned assembly method. It is also possible to connect multiple prefabricated units 1 together vertically, and then assemble multiple groups of sub-units 1 together circumferentially to form the required wave-breaking chamber module.

[0061] It is also very convenient for subsequent dismantling. After taking the wave-breaking chamber module out of the water, first split the wave-breaking chamber module into multiple prefabricated modules, and then split the prefabricated modules into multiple prefabricated units 1.

[0062] In a preferred embodiment of the present application, the structure of the prefabricated unit 1 is optimized. Specifically, Figure 3 and 4 As shown, a connecting plate 3 with screw holes is provided on one circumferential side of the prefabricated unit 1 of this embodiment, and the connecting plate 3 of the adjacent prefabricated unit 1 is overlapped to the circumferential side of another prefabricated unit 1 and the two prefabricated units 1 are connected as a whole by inserting bolts.

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

[0064] The connection plate 3 is provided with a plurality of screw holes evenly spaced in the axial direction, and the other circumferential side of the prefabricated unit 1 is provided with a plurality of corresponding screw holes evenly spaced in the axial direction. When two prefabricated units 1 need to be assembled together, it is only necessary to overlap the connection plate 3 of one prefabricated unit 1 to the circumferential side of the other prefabricated unit 1, align the screw holes at the overlap one by one in the radial direction, and 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 desired prefabricated module can be formed.

[0065] Furthermore, this embodiment optimizes the interlayer connection structure of the above-mentioned prefabricated unit 1. Specifically, Figure 3 and4 As shown, a plurality of groups of interlayer fixing structures arranged at intervals along the circumferential direction are provided on the circumferential outer side of the prefabricated unit 1, and the interlayer fixing structure includes two fixing seats 4 arranged at intervals along the vertical direction, and one fixing seat 4 in the same group of fixing seats 4 is provided with a vertically protruding boss 5 on a side relative to the other fixing seat 4, and a limiting groove 6 is provided on a side relative to the boss 5 on the other fixing seat 4, and the axially adjacent prefabricated units 1 are fixedly connected as a whole by the boss 5 being clamped in the limiting groove 6.

[0066] The boss 5 of this embodiment can be a protruding structure arranged on the upper fixing seat 4 of the same group, or a protruding structure arranged on the lower fixing seat 4 of the same group, as long as the corresponding connection function is met. Figure 3 and 4 As shown, the boss 5 of this embodiment is a protruding structure arranged 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 groups of interlayer fixing structures are arranged on the outer circumference of each prefabricated unit 1, and the two groups of interlayer fixing structures are arranged at positions close to the circumferential side of the prefabricated unit 1.

[0067] The boss 5 is a protruding columnar structure extending out of the corresponding prefabricated unit 1 in the axial direction, that is, when two axially adjacent prefabricated units 1 are assembled together, the boss 5 and the boundary line of the two prefabricated units 1 overlap in the horizontal direction.

[0068] When two axially adjacent prefabricated units 1 need to be fixedly connected as one, 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 tightly, in this embodiment, a first through hole 7 is provided on the boss 5 that penetrates the boss 5 along the tangential direction, and a second through hole 8 is provided on the fixing seat 4 with a limiting groove 6 that penetrates the fixing seat 4 and the limiting groove 6 along the tangent. After the boss 5 is inserted into the limiting groove 6, it is fixedly connected with the limiting groove 6 by bolts penetrated in the first through hole 7 and the second through hole 8.

[0070] That is to say, 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 fixing seat 4 corresponding to the limiting groove 6 are aligned in the horizontal direction, and by driving bolts into the aligned first through hole 7 and second through hole 8, and tightening the bolts to fix the fixing seat 4 corresponding to the boss 5 and the fixing seat 4 corresponding to the corresponding limiting groove 6 as one, the corresponding two prefabricated units 1 can be tightly and firmly assembled together.

[0071] In other embodiments of the present application, the present embodiment optimizes the above-mentioned pile guide module. Specifically, Figure 1As shown, the pile guide module of the present application includes a pile guide 2 and a pile clamp 11 fixed on the pile guide 2 and located below the guide seat 9 for limiting the downward movement of the wave-breaking chamber module. The pile guide 2 of the present application is a pipe pile structure inserted on the seabed, and a lifting ear structure is provided at the upper end of the pile guide 2 for easy lifting. The pile clamp 11 is a hoop structure, which is sleeved on the pile guide 2 and then fixed on the pile guide 2 by tightening the bolts.

[0072] The outer side of the prefabricated unit 1 corresponds to a guide seat 9 of the prefabricated unit 1. Figures 1 to 4 As shown, a plurality of guide seats 9 are provided on the circumferential outer side surface of the prefabricated unit 1, and guide holes 10 for the prefabricated unit 1 to pass through are opened on the guide seats 9, and the guide holes 10 in the guide seats 9 of the axially adjacent prefabricated units 1 are vertically aligned.

[0073] After the prefabricated units 1 are assembled into the wave-breaking chamber module, the guide holes 10 on all the guide seats 9 in the same axial direction are aligned, and the guide piles 2 can be conveniently inserted into the aligned guide holes 10 to complete the connection between the guide piles 2 and the sub-units 1. The guide piles 2 are limited to the non-vertical movement of the sub-units 1, and the pile clamp is located below the guide seat 9, so that the prefabricated unit 1 can be placed on the pile clamp to complete the arrangement of the wave-breaking chamber module.

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