Problems solved by technology

As far as the various air-permeable breakwaters, floating breakwaters and other special breakwaters are concerned, there are considerable difficulties in blocking and reducing long-period waves. Effective, but there is no report on breakwaters that can effectively reduce waves with a period greater than 6 seconds

Embodiment approach 1

[0037] 1. First, the piling ship fixes the fixed pile 4 with the stopper 12 in the water area at a designated position.

[0038] 2. At the same time, assemble the surface component 1, underwater component 2 and floating body 3 of the unit module together on the shore. And install the columnar sleeve 11 that links to each other with fixed pile 4 on two in the four combination laths 6 of water surface member 1. And assemble the required number of unit modules.

[0039] 3. Then, load the assembled unit modules on the lifting vessel.

[0040] 4. After the crane ship arrives at the destination, hoist the unit modules into the water so that each unit module floats near the fixed pile 4 .

[0041] 5. Use the crane boat again to lift the ends of the combined slats installed with the columnar sleeve 11 one by one, and insert the columnar sleeve 11 into the fixed pile 4, and be blocked by the stopper 12.

Embodiment approach 2

[0043] 1. First, the crane ship releases the anchoring system 5 into the water area at a designated position.

[0044] Steps 2, 3, and 4 are the same as in Embodiment 1.

[0045] 5. Use the crane again to lift the ends of the combined slats installed with the columnar sleeve 11 one by one, and connect the anchor system 5 with the columnar sleeve 11 .

Abstract

The invention discloses a flexible wave absorbing device for efficiently reducing long period waves in a shallow water area. Each unit module comprises a water surface component, an underwater component, floating bodies and a fixed device. Four combined battens of each water surface component clamp the end of the corresponding underwater component through penetrating holes via nuts and bolts, anda wave absorbing body is formed. The floating bodies are fixed to the water surface components through flexible tying bands via the nuts and bolts in the length direction of the combined battens. Twoof the combined battens of each water surface component are connected with the corresponding fixed device. For connection between the unit modules, one fixed device is used in common at the corresponding position. According to the size and shape of a wave absorbing water area interval, the number of the unit modules and the overall enclosure shape are determined, and finally the multiple unit modules are connected. The flexible wave absorbing device has the beneficial effects that the structure is simple and light, transport is convenient, fast mounting and migration can be achieved, repeatedutilization can be achieved, and cost is low; and the flexible wave absorbing device can be arranged temporarily or for a long time, and especially has efficient blocking and reducing functions for the long period waves in the shallow water area.

Description

technical field [0001] The invention relates to a floating wave-eliminating device, in particular to a flexible wave-eliminating device for efficiently reducing long-period waves in shallow waters. Background technique [0002] Breakwater is a protective structure commonly used by coasts, ports and wharves to resist the erosion of open sea waves. The common ones are: traditional breakwater, air-permeable breakwater, floating breakwater, and other special breakwaters. [0003] After the traditional breakwater builds a solid foundation at the bottom of the water, large stones or large reinforced concrete blocks are piled on the foundation from the bottom of the water to above the water surface to build a stable dam structure. The project is huge, and the cost increases sharply with the increase of water depth. When the water depth is very deep or the bottom soil is soft, it is impossible to build traditional breakwaters. Moreover, it cuts off the water exchange and damages ...
