Because the second wave dissipating structure 42 is located at the lower part of the first wave dissipating structure 41, the second wave dissipating structure 42 is always below the water surface during construction, so as to reduce the strength of the submerged waves, and at this time, the difficulty of installation of the installer below the water surface is greatly reduced by a hanging manner; meanwhile, the effect of reducing the intensity of the submerged swell can be enhanced by using the swing of the second wave-attenuating structure 42, and the water permeability is not greatly affected.

The second wave dissipating structure 42 is connected to said first wave dissipating structure 41.

Specifically, the first flexible member 44 is a flexible rope or a spring rope, and the outer side of the flexible rope or the spring rope can be provided with an anti-corrosion plastic package, so as to increase the anti-corrosion probability of the flexible rope or the spring rope.

As shown in fig. 16, the adjacent foundations 3 are provided with the first wave-dissipating structures 41 extending toward the other foundations 3, and one or two or more first wave-dissipating structures 41 on each foundation 3 may be provided, in this case, a more preferable scheme is that: thereby changing the advancing path of the wave into a multi-bending path, and further achieving the purpose of reducing the wave height.

A part of the foundation 3 is located below the water surface 37 and the bottom of the foundation 3 is inserted into the water bottom surface 39.

Because the second wave dissipating structure 42 is located below the first wave dissipating structure 41, the second wave dissipating structure 42 is often below the water surface 37, and the second wave dissipating structure 42 is flexibly connected to at least one side of the steel cylinder 33, so that when the low water surface 37 surge impacts the second wave dissipating structure 42, the second wave dissipating structure 42 swings, thereby disturbing the low water surface 37 surge, and further reducing the strength of the low water surface 37 surge.

The second wave dissipating structure 42 has a gap with the adjacent steel cylinder 33, so that the second wave dissipating structure 42 can achieve the purpose of water permeation and wave impermeability, thereby greatly reducing the influence on the marine ecological environment.

By means of the first flexible member 44 being connected to the attachment member 43, the difficulty of installing the second wave dissipating structure 42 below the water surface can be greatly reduced compared to the manner of welding the second wave dissipating structure to the steel cylinder 33.

The first flexible member 44 and the corresponding attachment member 43 may also be fastened.

Because the second wave dissipating structure 42 is located at the lower part of the first wave dissipating structure 41, the second wave dissipating structure 42 is always below the water surface during construction, so as to reduce the strength of the submerged waves, and at this time, the difficulty of installation of the installer below the water surface is greatly reduced by a hanging manner; meanwhile, the effect of reducing the intensity of the submerged swell can be enhanced by using the swing of the second wave-attenuating structure 42, and the water permeability is not greatly affected. Specifically, the first flexible member 44 is a flexible rope or a spring rope, and the outer side of the flexible rope or the spring rope can be provided with an anti-corrosion plastic package, so as to increase the anti-corrosion probability of the flexible rope or the spring rope.

As shown in fig. 18-20, in a further preferred manner, the second wave dissipating structure 42 includes second wave dissipating structure units 45 sequentially arranged along the vertical direction, the first flexible member 44 is connected to the second wave dissipating structure units 45, and when the second wave dissipating structure units 45 are installed, they can be independently installed below the water surface, and the second wave dissipating structure units are better manufactured and installed than the second wave dissipating structure 42 which is installed below the water surface as a whole.

The second wave dissipating structure 42 includes second wave dissipating structure units 45 sequentially arranged along the vertical direction, and the first flexible member 44 is connected to the second wave dissipating structure units 45. When installed, the second wave dissipating structure unit 45 may be installed separately below the water surface, and may be manufactured and installed better than the second wave dissipating structure 42. At least two adjacent second wave dissipating structural units 45 are flexibly connected by a second flexible member 46. The second flexible member 46 is a flexible rope or a spring rope, and the outer side of the flexible rope or the spring rope can be provided with an anti-corrosion plastic package so as to increase the anti-corrosion probability of the flexible rope or the spring rope. The second wave dissipating structure unit 45 is a plate body, a sphere or a cylinder, and when the second wave dissipating structure unit 45 is a cylinder, two ends of the second wave dissipating structure unit 45 are open. Thereby increasing the swinging quality of the second wave dissipating structural unit 45 to achieve a better wave dissipating effect.

At the time of manufacturing, the concrete cylinder 32 and the first wave dissipating structure 41 may be integrally prefabricated; the concrete cylinder 32 is preferably a reinforced concrete cylinder. The first wave attenuating structure 41 is capable of increasing the radial stiffness of the concrete cylinder 32; a portion of the concrete cylinder 32 is located above the water surface 37, the remaining portion is located below the water surface 37, the steel cylinder 33 is all located above the water surface 37, and the lower portion is inserted into the water bottom surface 39.

The upper portion of the third flexible member 453 is connected to the portion of the reinforced concrete cylinder 32 above the water surface 37.

As shown in fig. 21, when waves or sea wind are applied to the upper side of the cylinder 30 and the external load F _{Outer part} is applied, the soil under the water bottom surface 39 can apply the passive soil pressure F _{Quilt is covered with} opposite to the external load F _{Outer part} to the cylinder 30, so that the overall dead weight of the large-diameter composite cylinder according to this embodiment can provide most of the resistance to the external load F _{Outer part} to meet the requirement, without providing all of the resistance to the external load F _{Outer part} , and thus the resistance requirement of the large-diameter composite cylinder can be effectively reduced under the requirement of relative stress.

The concrete cylinder 32 is provided with openings at both ends, and the steel cylinder 33 is provided with openings at both ends.

According to the different wave heights of the water surface 37, the length of the concrete cylinder 32 along the length direction is A, and A is more than or equal to 7m and less than or equal to 30m, so that the concrete cylinder can meet the requirement that the height direction is from +2 to +12m above the water surface 37 to-15 to-5 m below the water surface 37, and the general use of the large-diameter combined cylinder in the ocean is met.

On the basis of the above, it is further preferable that the maximum outer diameter of the steel cylinder 33 is 20.5 m.ltoreq.R1.ltoreq.40 m. The wall thickness of the steel cylinder 33 is T1, and T1 is more than or equal to 0.01m and less than or equal to 0.05m.

because the material used by the large single pile monopile is artificial materials such as concrete or steel, more fillers 31 such as silt, middle coarse sand and the like are filled in the steel cylinder 33 of the large-diameter combined cylinder, and the large-diameter combined cylinder is more green and environment-friendly, so that the cost is saved;

Because the filler of the traditional gravity breakwater revetment is formed by free slump, the large-diameter combined cylinder can save more than two thirds of internal filler.

Meanwhile, as shown in fig. 22, the packing 31 generates normal earth pressure to the wall of the steel cylinder 33.

As shown in fig. 23, a micro-segment study on the wall of the steel cylinder 33 shows that, due to the "cloth bag" effect generated by the steel cylinder 33, the normal soil pressure brings about a circumferential pulling force on the wall of the steel cylinder 33, so that the internal filler and the cylinder form an integral effect, and the pulling force brings about additional cylinder rigidity like a cloth bag filled with sand, thereby reinforcing the structural rigidity and the integral stability of the steel cylinder 33.

Specifically, the second flexible member 46 is a flexible rope or a spring rope, and an anti-corrosion plastic package can be arranged on the outer side of the flexible rope or the spring rope so as to increase the anti-corrosion probability of the flexible rope or the spring rope.

On the basis of the above, the wall thickness of the concrete cylinder 32 is more preferably T2, and 10 is less than or equal to T2/T1 is less than or equal to 200, and under the condition of the same external diameter specification, the wall thickness required by the steel cylinder 33 is far smaller than the wall thickness of the concrete cylinder 32, so that the whole weight of the large-diameter combined cylinder is much lighter than that of the reinforced concrete cylinder with the same external diameter specification, and more existing prefabrication construction processes and equipment can meet the transportation and sinking construction.

As shown in fig. 24 to 27, a lateral stopper is provided between the concrete cylinder 32 and the steel cylinder 33, and serves to restrict the horizontal movement of the concrete cylinder 32 relative to the steel cylinder 33.

Specifically, the groove 322 is disposed at the bottom of the concrete cylinder 32, and the protrusion 332 is disposed at the top of the steel cylinder 33.

Specifically, the groove 322 is disposed in a circle along the circumference of the wall of the concrete cylinder 32, and the protrusion 332 is disposed in a circle along the circumference of the wall of the steel cylinder 33, so that the cooperation of the groove 322 and the protrusion 332 can realize a closed arrangement between the concrete cylinder 32 and the steel cylinder 33.

In addition to the above, it is further preferable that the grooves 322 are filled with flexible filler layers 323, and the flexible filler layers 323 are filled on both sides of the protrusions 332.

Because in construction, because the bulge 332 of steel cylinder 33's top in inserting recess 322 can't be with recess 322 complete accurate cooperation, at this moment, the intussuseption of recess 322 is filled with flexible filling layer 323, can make between concrete cylinder 32 and the steel cylinder 33 reach better sealed effect, simultaneously, because concrete cylinder 32 and steel cylinder 33 general size are great, in the installation concrete cylinder 32 and steel cylinder 33 in-process, when recess 322 and bulge 332 cooperation installation, can play the cushioning effect to reduce impact and vibrations between concrete cylinder 32 and the steel cylinder 33. Specifically, the flexible filler layer 323 includes asphalt, rubber, or the like.

On the basis of the above, it is further preferable that the bottom of the concrete cylinder 32 is connected with the steel cylinder 33. The concrete cylinder 32 is connected with the steel cylinder 33, so that the concrete cylinder 32 and the steel cylinder 33 are convenient to hoist integrally; secondly, as a specific measure for restricting the lateral movement of the concrete cylinder 32 with respect to the steel cylinder 33.

As shown in fig. 28, in the above-described manner, it is further preferable that a drag reduction means is provided at the lower portion of the drum 30, the drag reduction means being for reducing drag during sinking of the drum 30.

The drag reduction facility includes a high-pressure water facility 34, the high-pressure water facility 34 is disposed at the lower portion of the steel cylinder 33, and the high-pressure water facility 34 is used for reducing the resistance of the sinking end portion of the steel cylinder 33, wherein the high-pressure water facility 34 is preferably a high-pressure water gun.

An air curtain 35 is provided at the lower portion of the steel cylinder 33, and the air curtain 35 serves to reduce the sinking side resistance of the steel cylinder 33.

The wave-attenuating facility 5 and the floating platform 7 are connected through a floating bridge 8 or a floating tunnel 65. When vessel transit is required, the use of a levitation tunnel 65 is preferred. The floating bridge adopts a bridge pier scheme of two pontoon pontoons or multiple pontoons. The suspension tunnel adopts a scheme of two to three pontoons or one pontoon or a plurality of pontoons for anchoring the main structure of the tunnel above the water surface by adopting double pipes (considering the bidirectional traffic from the wave-eliminating facility 5 to the floating platform 7 and from the floating platform 7 to the wave-eliminating facility 5). The first pontoons at the two ends are provided with vertical elevators, so that traffic is conveniently transported from the pontoons above the water surface to the immersed tunnel pipe bodies (transverse channels 653).

The distance between the wave eliminating facility 5 and the floating platform 7 is preferably 50-200 m when a harbor basin is not needed, and is mainly controlled by factors such as mooring system arrangement, wave surmounting amount, plane cheapness allowed by the platform and the like.

On the basis of the above, it is further preferable that the wave-attenuating device 5 is inserted into the water bottom surface 39 at the lower portion thereof.

According to the floating platform system disclosed by the application, the influence of adverse environmental load (mainly wind and wave environmental load) on the covered water area 71 is effectively reduced or eliminated through at least one circle of wave eliminating facilities 5, so that the covered water area 71 is very little influenced by wind and wave environment, a calm covered water area 71 is formed, the covered water area 71 can be used for constructing the floating platform 7, and the floating platform 7 is allowed to slightly move up and down and slightly move left and right along with tide rise and tide fall through the anchor cables 68 at the position of limiting the floating platform 7, so that the cost for fixing the floating platform 7 in water is greatly reduced. Compared with the existing filling type platform, the floating platform has the advantages that the material consumption of the floating platform is greatly reduced; and greatly reduces the construction difficulty.

Example 5

As shown in fig. 1-12, the present application further discloses a construction method for the floating platform device according to embodiment 1, 2 or 3, which includes the following steps:

S1, constructing the wave eliminating facilities 5, and enclosing the covered water area 71 by utilizing the wave eliminating facilities 5;

S2, constructing the floating platform 7 in the covered water area 71.

According to the construction method for the floating platform device, the surrounding wave eliminating facilities 5 enclose the covered water area 71 to form a calm water area, and the floating platform 7 is constructed in the water area, so that the construction of the floating platform 7 is free from the influence of large waves, and the window period of the construction of the floating platform 7 is greatly prolonged.

Specifically, the floating platform 7 comprises a plurality of floating box units 1 which are arranged in an array, and the wave eliminating facility 5 comprises a prefabricated cylinder 30;

after prefabrication of the concrete cylinders 32 on the line 10 of the prefabrication plant, the line 10 is also able to prefabricate the buoyancy tank units 1.

The principle of the barrel 30 as and after sinking is as follows:

–L+Gc+Gs–Bc–Bs+S–T–F＝0

The formula L: hanging force, gc: concrete cylinder 32 gravity, gs: steel cylinder 33 gravity, bc: concrete cylinder 32 buoyancy, bs: steel cylinder 33 buoyancy, S: suction, when necessary, T: the resistance of the end of the steel cylinder 33 depends on the soil parameters of the stratum and the drag reduction effect of high-pressure water, F: the magnitude of the steel cylinder 33 sidewall drag is dependent upon the backfill friction angle and height, as well as the drag reduction effect of the outer earthen formation of the barrel 30 and the air curtain 35.

The weight of the cylinder 30 is G, g=gc+gs; the buoyancy of the cylinder 30 is B, b=bc+bs.

After the combined drum 30 is submerged to the design elevation, the high pressure water installation 34 and air curtain 35 are stopped. The sinking posture control of the cylinder is controlled by combining the pressure regulation of the high-pressure water facilities 34 and the air curtain 35 at different positions, the arrangement of a GPS and an inclinometer at the top of the cylinder, and the like. After completion, the cylinder is filled with sand or part of the sand, if necessary, the anti-scour structure 310 is piled up outside the steel cylinder 33 (sand filling height and vibration flushing necessity depend on the magnitude of the open sea load), the inside of the cylinder 30 is filled with sludge and partially solidified (solidification necessity depends on the magnitude of the open sea load), and at the same time, the second wave eliminating structure 42 is submerged under water, and the operator flexibly connects the second wave eliminating structure 42 with the corresponding attachment 43.
