Stepped plate type pile foundation permeable breakwater

Abstract

The invention discloses a stepped plate type pile foundation permeable breakwater. The breakwater comprises pile foundation components on the lower portion and a wave blocking structural component onthe upper portion. The wave blocking structural component is a multi-stage stepped type cavity structural body. A plurality of through holes are formed n the two side walls and the rear wall of the cavity structural body correspondingly. The pile foundation components are a plurality of transverse bent frames arranged at equal intervals in the breakwater length direction. Seen in the longitudinaldirection of the transverse bent frames, a plurality of pile legs are arranged in the multi-stage step direction of the wave blocking structural component equally. The stepped plate type pile foundation permeable breakwater provided by the invention has the good wave blocking effect and can be used for effectively reducing transmitted wave height behind the breakwater and maintaining mooring conditions in a port, in addition, the stress characteristic is good, and the structure is not prone to being damaged by waves; and besides, the breakwater is an environment-friendly breakwater, construction and maintenance are convenient, and the breakwater is applicable to deep water areas where traditional forms of breakwaters are not suitable for being built.

Description

technical field [0001] The invention belongs to the technical field of ocean engineering, and relates to a breakwater, more specifically, to a permeable breakwater with stepped plate pile foundation. Background technique [0002] The air-permeable breakwater is mainly composed of a pile foundation and an upper anti-wave structure. Among them, the main function of the upper structure is to resist the transmission of wave energy, submerged into the water to a certain depth, so as to effectively reduce the wave height in the port. The upper structure can adopt box type or plate type. The slab structure is simple to construct, less expensive, and light in weight. In recent years, the research on this kind of breakwater structure has attracted more and more attention from the marine engineering community. [0003] At present, there are various types of plate breakwaters, such as horizontal plate, vertical plate, multi-layer plate, composite plate and perforated plate. Domestic ...

AI Technical Summary

Problems solved by technology

Most of the slabs and vertical slabs of these structures use the whole slab as a breakwater, the upper slab is located on the free water surface, and the lower slab dives to a certain depth to block the wave propagation and play the role of wave dissipation, but the wave dissipation effect of the breakwater still needs to be improved

At the same time, the front vertical plate and lower plate of this type of breakwater are generally subjected to large wave forces, which will be detrimental to the stability of the breakwater. The design of the open-hole plate can reduce the force on the plate, but the existing open-plate breakwater only The surface is open. In order not to affect the wave dissipation effect, the opening ratio of the plate is generally less than 30%, and the force-bearing area of ​​the plate is still relatively large, and the force of the breakwater structure has not been effectively reduced.
