A vertical breakwater with open caisson

Abstract

The invention discloses a perforated caisson vertical groyne. The perforated caisson vertical groyne comprises a caisson and a breast wall, wherein separation walls or separation plates are arranged in the caisson to form multiple cells; a caisson hole is formed in a wave surface exterior wall at the upper part of the caisson; the cell behind the caisson hole serves as a wave eliminating chamber; sand is filled in the other cells of the caisson besides of the wave eliminating chamber; the wave eliminating chamber is provided with a top plate; the top plate is provided with multiple water inlets; the breast wall is arranged at the top of the top plate; an inclined surface is arranged on a wave side of the breast wall, and is provided with multiple water outlets; and the water outlets are communicated with the water inlets formed in the top plate through pipes. The perforated caisson vertical groyne uses self kinetic energy of waves to eliminate the energy, reduces the wave force thereof, reduces the groyne back wave height, reduces the wave overtopping rate, reduces the caisson size, reduces the work amount, saves investments, is convenient to construct, can fully use self kinetic energy of water, saves the energy, and protects the environment.

Description

technical field [0001] The invention relates to a breakwater, in particular to a novel open caisson vertical breakwater which utilizes the kinetic energy of waves to dissipate energy, and belongs to the innovative technology of the open caisson vertical breakwater. Background technique [0002] The vertical embankment has the advantages of good integrity of the dike body, small installation workload on the water, no need for large lifting equipment, and fast construction progress. Open caisson vertical embankment can be used to reduce the reflection in front of the wall, shock wave pressure and the transmitted wave caused by overcoming waves, etc. Compared with non-open caisson breakwater, it has the advantages of small hydraulic pressure and small wave height reflection. [0003] However, when the elevation of the roof of the wave dissipation chamber is relatively low, the waves will exert an upward force on the roof, which is not conducive to the stability of the breast wa...

Problems solved by technology

[0003] However, when the elevation of the roof of the wave dissipation chamber is low, the waves will exert an upward force on the roof, which is not conducive to the stability of the breast wall and the roof

If the roof elevation is raised, the height of the caisson needs to be increased, which will increase the volume of the caisson and increase the difficulty of prefabrication and transportation; it will increase the amount of work and increase the cost, which is not environmentally friendly and economical; may also adversely affect
