Ladder-type permeable breakwater

Abstract

The invention discloses a ladder-type permeable breakwater. The ladder-type permeable breakwater includes a ladder-type structure and a lower structure; the ladder-type structure is fixed to the lowerstructure; the ladder-type structure is provided with a plurality of steps, each step is provided with a hollow chamber, and all the chambers are communicated with a bottom pipeline; open holes are formed in the side faces and tops of the steps at the weave approaching side; open holes are formed in the side faces of the steps at the inner side. According to the ladder-type permeable breakwater,on the basis of good wave dissipation effect, the environment protection idea is also taken into account; the ladder-type permeable breakwater also has the effect of a landscape breakwater, and waterbody exchange is good; the ladder-type permeable breakwater is suitable for water of different depth and marine geology environment and meets the requirements for green harbors which have small influence on sea area hydrodynamic environment.

Description

technical field [0001] The invention relates to the technical field of breakwaters, in particular to a stepped air-permeable breakwater. Background technique [0002] As an important part of the port hydraulic structure, the breakwater can maintain the stability of the waters in the port and ensure the safety of ships entering and exiting, berthing and loading and unloading operations. [0003] At present, traditional breakwaters are mostly non-permeable slopes and vertical dikes, but the circulation of water in the shelter area is limited, and the hydrodynamic environment of the surrounding sea area is greatly changed, which is prone to changes in sediment erosion and deposition, changes in the coastline, and changes in the harbor. Water pollution and other issues. Slope dikes are mostly riprap structures. In some areas of our country, the site conditions are poor, stone materials are relatively scarce and the cost is high; vertical dikes will form standing waves with high...

Problems solved by technology

[0003] At present, traditional breakwaters are mostly non-permeable slopes and vertical dikes, but the circulation of water in the shelter area is limited, and the hydrodynamic environment of the surrounding sea area is greatly changed, which is prone to changes in sediment erosion and deposition, changes in the coastline, and changes in the harbor. Water pollution and other issues

Slope dikes are mostly riprap structures. In some areas of our country, the site conditions are poor, stone materials are relatively scarce and the cost is high; vertical dikes will form standing waves with high wave pressure due to the reflection of straight walls, which will affect the water flow in the channel and the dike body. adverse effects on stability
