Combined type breakwater

Abstract

The invention discloses a combined type breakwater. The combined type breakwater comprises a connecting structure and a plurality of breakwater units, wherein each breakwater unit comprises a box structure and a mooring structure, wherein the box structure comprises a wave approach side plate and a wave back side plate, a first floating plate is rotationally connected on the wave approach side plate, and a second floating plate is rotationally connected on the wave back side plate; the first floating plate and the second floating plate swing up and down along with the motion of waves; the boxstructure is flexibly connected with the seafloor through the mooring structure and floats on the water surface; supporting plates connected with the wave approach side plate and the wave back side plate are respectively arranged on the two sides of the box structure; and the close supporting plates of the adjacent floating breakwater units are connected through a connection structure. The floating breakwater has a good wave dissipating performance, a high safety performance of the structure self, a simple structure and convenience in construction and maintenance.

Description

technical field [0001] The invention belongs to the technical field of marine engineering, in particular to a combined breakwater. Background technique [0002] The breakwater is an important port and coastal engineering structure, which is mainly used to prevent the intrusion of waves on the port waters, to provide stable and safe berthing conditions and operating waters in the port, and to improve the design conditions of the hydraulic structures in the port. Protection of port hydraulic structures. In addition, on sandy and muddy coasts, breakwaters can also reduce or prevent sediment from entering the port. For frozen ports, breakwaters can also reduce the flow of ice outside the port into the port. The structural forms of breakwaters mainly include slope type, vertical type, hybrid type, air-through type and floating type, among which the first three are traditional bottom-seat type breakwaters. The traditional bottom-seat breakwater can better protect the waters in t...

Problems solved by technology

However, the bottom-seat breakwater has its limitations: with the increase of the project water depth and the deterioration of the foundation conditions, the project cost increases sharply, and the construction difficulty increases; the water circulation in the shelter area is restricted, and it is easy to produce sediment and sand deposits in the port. water pollution

[0004] However, there are also many factors that limit the application of floating breakwaters. The existing floating breakwater structures mainly have the following disadvantages: 1. The existing floating breakwaters have the disadvantage of poor wave dissipation effect, especially when the wave cycle is long. 2. For some floating breakwaters with complex structures with better wave dissipation performance, although there are many structural types proposed at home and abroad, but When there are big waves, the floating breakwater structure bears a large wave force, and the safety of the structure is reduced.
