energy dissipation caisson

Abstract

The invention provides an energy dissipation caisson. The energy dissipation caisson comprises a caisson body and is characterized in that the caisson body is an opened square caisson body defined by the front wall, the rear wall and two side walls; the interior of the square caisson body is separated by vertically-arranged partition walls into a plurality of grid cabins, and the grid cabins comprise a sand filling grid cabin with the bottom, bottomless side grid cabins and a bottomless rear grid cabin; the sand filling grid cabin is arranged in the middle front portion inside the square caisson body and filled with sand, the side grid cabins are located on the two sides of the sand filling grid cabin, the rear grid cabin is arranged behind the sand filling grid cabin, and through openings are formed in the positions, located between the side grid cabins on the same side, of the upper half portions of the partition walls; through openings are formed in the positions, between the rear grid cabin and the adjacent side grid cabins, of the upper half portions of the partition walls, and open holes are formed in the positions, corresponding to the positions of the two side grid cabins, of the upper edge of the front wall of the square caisson body; and wave energy can be effectively dissipated, wave reflection and wave force can be reduced, the structure is light, and the imposed load of the structure to the foundation can be obviously reduced.

Description

technical field [0001] The invention relates to the field of port and coastal engineering, in particular to an energy dissipation caisson. Background technique [0002] The caisson belongs to the traditional port engineering structure and is widely used in port and coastal engineering such as breakwaters, wharves, and revetments. In recent years, with the rapid development of port and coastal engineering construction, it has become more and more common to construct port constructions in open waters with large waves, deep water, fast currents, and relatively weak foundations. Therefore, the structural requirements for caissons are also increasing. high. In the prior art, the caisson usually adopts the traditional straight wall structure, and the front wall of the caisson is an impermeable vertical wall, which can meet the basic needs of engineering construction, but there are still large wave reflections in front of the structure, large force, and the seabed in front of the ...

AI Technical Summary

Problems solved by technology

In the prior art, the caisson usually adopts the traditional straight wall structure, and the front wall of the caisson is an impermeable vertical wall, which can meet the basic needs of engineering construction, but there are still large wave reflections in front of the structure, large force, and the seabed in front of the structure is easy to scour , higher requirements on the seabed bearing capacity, etc. At the same time, when the wave height is large and the water depth in front of the structure is relatively small, the wave may break and the structure will suffer a strong impact, resulting in a sharp increase in the wave force on the caisson and disappearing. poor wave effect
