Problems solved by technology

In the design of breakwaters, wave pressure is generally used for design, and some wave dissipation measures are mainly to reduce the effect of wave pressure on breakwaters, without considering the influence of wave suction
[0004]In fact, because the wave elements in front of the building, the water depth conditions in front of the embankment, the bottom slope and the outline size of the foundation bed are all factors that affect the wave shape in front of the embankment, Different wave forms lead to different forms of wave action on the breakwater, so there will be great safety hazards in the design and construction of breakwaters that simply consider wave pressure

Embodiment

[0039] Such as figure 1 It is known that the wave-dissipating structure is 2m high and 4m long. The front wall of the wave-dissipating empty box 2 is divided into two rows of symmetrically distributed 6 oval-shaped wave-dissipating holes 1, with 3 in the first row and 3 in the second row. The left and right clear distance of wave hole 1 is 1m, the upper and lower clear distance is 0.5m, the long axis is 0.15m, and the short axis is 0.1m. Inside the parapet of the breakwater, the distance between the upper surface of the wave-dissipating structure and the top of the parapet is 1m, the length of the wave-dissipating blade 4 is 1m, and the length of the rotating shaft 5 of the wave-dissipating blade is 4m. The design high water level of the breakwater to be built is 3.5m, and the extreme high water level is 4.39m. The wave height is 2.8m, The wave height is 3.8 m, the design wavelength is 50.50 m, the return period is 50 years, and the water depth in front of the embankment ...

Abstract

The invention discloses a communication type breakwater wave dissipation structure for resisting wave suction force, belonging to the construction field of a breakwater structure. The breakwater wave dissipation structure comprises a wave dissipation hole (1), a front wave dissipation empty case (2), a rear wave dissipation empty case (3), wave dissipation blades (4), a wave dissipation blade rotating shaft (5), a communication hole (6), a rear arc wall of the rear wave dissipation empty case (7) and a communication pipe. The breakwater wave dissipation structure is provided with the front wave dissipation empty case and the rear wave dissipation empty case, the structure integrally forms a communication vessel by the communication pipe, effectively reduces action of wave suction force on a breakwater, reduces wave raising in front of the breakwater, reflection coefficient and levee crown overtopping and greatly improves the wave dissipation effect of the breakwater. Meanwhile, when wave troughs act on, anti-slipping and anti-tipping stability check formulas of a breast wall of the breakwater under the action of wave suction force are proposed, and after verification, the breakwater meets the stability requirement.

Description

[0001] Technical field: [0002] The invention relates to a connected breakwater wave dissipation structure resisting wave suction, which can be widely used in the design field of breakwaters with large water depth and strong wave action. [0003] Background technique: [0004] Breakwaters, built in ports on open coasts, bays or islands, are a common type of coastal engineering structure used to prevent waves from invading the harbor and ensure that the harbor has stable waters. It is mainly composed of walls, superstructure and foundation bed. [0005] The wall and superstructure bear the main wave force, which is divided into wave pressure and wave suction. When the wave crest acts on the breakwater, it is wave pressure, and when the wave trough acts on the breakwater, it is wave suction. The acting direction of the wave pressure points to the breakwater, causing the embankment to fall inward, while the acting direction of the wave suction deviates from the breakwater, c...
