Embodiment 1

[0047] see Figure 1-13 , a floating wave dissipation and shock protection system, which is composed of multiple groups of single wave dissipation and shock protection units through a connection structure, and assembled into a surrounding protection structure or a side pile type protection structure according to actual protection requirements; The surrounding protective structure and the side-row pile-type protective structure are connected to the foundation of the structure to be protected through the anchor cable structure. By adopting the wave dissipation and shock protection system of the present invention, it can be directly fixed on the foundation of the structure to be protected, without additional construction and anchorage on the seabed, and is easy to construct; the wave dissipation and shock protection unit is an independent unit, which can be easily increased or decreased, and can be composed of different types of protection The barrier is suitable for the protecti...

Embodiment 2

[0058] The application method of the floating wave dissipation and anti-shock system includes the following steps:

[0059] Step 1. Selection of protective structure: According to the specific protection requirements of the structure to be protected, determine the size, foundation type and water depth parameters of the required protective structure, and calculate the design protection range, the number of wave dissipation and anti-shock units, the length of the anchor cable and the specific protection structure. Type of protective structure;

[0060] Step 2, Onshore assembly of protective structure: According to the protective structure formulated in Step 1, complete the basic structure of the protective system on land;

[0061] Step 3, transport and hoisting of the protective structure: transport the protective structure assembled on land to the target structure by the construction ship, and then hoist it to the design position;

[0062] Step 4, fixed connection of the prote...

Embodiment 3

[0066] In this embodiment, when the surrounding protection type is applied to a multi-leg structure, taking the offshore booster station 16 as an example, the wave dissipation and anti-shock unit is fixed on the pile foundation 15 through the anchor cable 9, and the hook 10 at one end of the anchor cable 9 is hung on the connecting ring. 8, the connecting ring 8 is connected to the wave dissipation and anti-shock unit through the fixed rod 7 welded on the hollow cylindrical box 2, and the other end is welded to the spherical fixed point 14 on the telescopic collar 11, which can be buckled according to the size of the pile foundation 13 adjust the inner diameter of telescopic collar 11 to adapt to different pile diameter foundations. After adjustment, tighten and tighten 12 so that telescopic collar 11 is firmly fixed on pile foundation 15.

Abstract

The invention relates to a floating type wave-absorbing and anti-impact system and an application method thereof. The system is formed by combining multiple sets of single wave-absorbing and anti-impact protection units through connecting structures, and the multiple sets of single wave-absorbing and anti-impact protection units are assembled into a peripheral protection structure or a side-row pile type protection structure according to actual protection requirements; the peripheral protection structure and the side row pile type protection structure are connected to a building foundation needing to be protected through anchor cable structures. The system is formed by connecting the cylindrical floating type wave-absorbing anti-impact units, the protection units are easy to mount and dismount, and protection of various types of offshore structures can be met.

Description

technical field [0001] The present invention relates to the field of marine engineering, in particular to a floating wave suppression and shock prevention system and an application method thereof. Background technique [0002] In recent years, the construction of offshore and distant sea projects such as cross-sea bridges, offshore wind power, and offshore oil and gas exploration in my country has been in full swing. With the frequent occurrence of extreme weather around the world, marine disasters have become more and more severe. Disaster waves, solitary waves, and drifting objects on the sea have intensified threats to offshore structures. , therefore, it is necessary to carry out technical research and development on the wave-absorbing shock protection of offshore structures. [0003] At present, the common wave dissipation measures are wave walls, breakwaters, wave piles, etc., and the common impact protection or anti-collision measures are mostly rubber fixed around the...
