Porous floating breakwater formed by splicing prefabricated components

Abstract

The invention relates to a porous floating breakwater formed by splicing prefabricated components, belonging to the filed of ocean engineering structures. The porous floating breakwater is characterized by comprising main structures formed by splicing hollow prefabricated components in different geometric shapes by longitudinal bridge members; the prefabricated components are closed hollow boxes formed by using an external elastic material to coat an internal rigid material; each box is provided with at least two round holes; a rigid block is fixed in each box, and the round holes penetrate through and are arranged on the rigid block; the surfaces of the prefabricated components are respectively provided with grooves; and the breakwater structure can have lengths in accordance with engineering needs by assembling a plurality of main structures. The invention has the advantages that the design is combined with a plurality of energy dissipation mechanisms, such as reflection resistance, energy peak consumption, turbulence energy consumption, porous seepage energy consumption, and the like, has good wave-absorbing effect, small wave-feeding force, convenient and rapid mounting and easy maintenance and is suitable for use in different water depth ranges.

Description

technical field [0001] The invention belongs to the field of marine engineering structures and relates to a porous floating wave-absorbing structure assembled from prefabricated components. Background technique [0002] In order to prevent the structures in ports and docks or ships from being affected by large waves, breakwater structures will be built in the project to protect the waters in the port. In the past, engineers used more fixed and bottom-sitting breakwaters, such as setting up vertical wall structures on rock-fill foundations. Because this type of structure is fixed on the bottom of the sea and protrudes from the sea surface, it can well block the entry of outer sea wave energy, but at the same time it also prevents the circulation of seawater in the inner and outer sea areas, and its construction cost will increase sharply with the increase of water depth. Slow down the pace of the port's development towards deep water. [0003] In recent decades, engineering...

Problems solved by technology

However, because it is only near the sea surface where the wave energy is concentrated and does not block the wave energy of the entire water depth, and the movement of the upper structure is difficult to control when the mooring system is connected, most floating breakwaters have much worse wave dissipation effect than traditional breakwaters.
