Abstract

The invention discloses a circular floating breakwater. It consists of multiple arc-shaped floating anti-wave units connected with the same radius of curvature, and is fixed on deep-water islands and reefs with anchor chains. There is no need to consider issues such as the direction of the main wave and wave diffraction, and a smooth circular water area is formed on the sea. The arc-shaped member has good mechanical performance, and the wave force acting on the circular floating breakwater is small and all pass through the center of the circle, so there is no overturning moment on the embankment. A single arc-shaped floating anti-wave unit can be prefabricated on land and installed at sea. Each arc-shaped floating anti-wave unit can float independently on the sea. Even if a section of the breakwater is damaged, the rest can still float on the sea. Function, to resist the attack of sea waves, only need to replace one or several sections of arc-shaped floating anti-wave units during maintenance, and the maintenance efficiency is high. The invention overcomes the disadvantage that the traditional breakwater is unsuitable for deep sea, has stable structural force and low maintenance cost, and is suitable for deep water sea areas with open surroundings, strong wave action and uncertain wave direction.

Description

A circular floating breakwater

technical field

The invention relates to a breakwater, in particular to a circular floating breakwater.

Background technique

A breakwater is a common building in coastal and marine engineering, and its function is to block the impact of waves and maintain a stable water surface. The traditional fixed breakwaters are mostly offshore breakwaters, and the foundation is fixed on the seabed, which has high requirements on the foundation. As the water depth increases, the cost will also increase, so it is not suitable for deep waters. Most of the traditional breakwaters are straight dikes. It is necessary to consider the direction of the largest main wave, so that the dike line is perpendicular to the direction of the largest main wave. The direction of the largest main wave needs to be obtained from the coastal wave data over the years, and there is often no relevant data in the deep sea. Moreover, there are problems such as wave diffraction at both ends of the dike for the straight breakwater, which weakens the wave prevention effect of the breakwater. In recent years, with the deepening of ocean development, the floating breakwater has attracted people's attention because of its simple structure, low cost and suitable for deep water compared with the fixed breakwater. However, most of the current studies on floating breakwaters focus on the structural form of single block breakwaters, and their overall form is still limited to straight dikes for offshore protection.

Contents of the invention

Aiming at the deficiencies of fixed breakwaters and linear breakwaters in the background technology, the purpose of the present invention is to provide a circular floating breakwater, which is suitable for deep water sea areas with open surroundings, strong wave action and uncertain wave direction, and improves the Floating breakwater performance.

In order to solve the problems of the technologies described above, the technical scheme adopted in the present invention is as follows:

The invention comprises a circular floating breakwater formed by connecting a plurality of arc-shaped floating anti-wave units with the same curvature radius.

Each arc-shaped floating breakwater unit is made of concrete or anti-corrosion reinforced concrete into a box structure, and each arc-shaped floating breakwater unit can independently float on the sea surface and be fixed in deep water with anchor chains On the reef.

The adjacent arc-shaped floating breakwater units are connected to each other by tenon joints to form an overall circular floating breakwater.

The deep underwater island reef is located in the circular floating breakwater.

The beneficial effects that the present invention has are:

After a number of arc-shaped floating breakwaters are formed into an integral circular breakwater, a closed circular water area can be formed on the sea. Due to the isotropic performance of the circle, it can effectively defend against waves in all directions in the ocean without considering the largest main force. Problems such as wave direction and wave diffraction, so that relevant offshore facilities and operations can be carried out safely in this water area, free from the impact and loss of wind and waves, such as fish farming in cages in circular breakwaters, construction of artificial reefs, etc., round Shaped breakwaters can also be used as the foundation of other offshore floating structures and platforms to effectively utilize sea space. The arc-shaped member has good mechanical performance, and the wave force acting on the circular floating breakwater is small and all pass through the center of the circle, so there is no overturning moment on the embankment. A single arc-shaped floating anti-wave unit can be prefabricated on land, installed and connected to form a circular breakwater at sea, without post-procedures such as cast-in-situ concrete, and each arc-shaped floating anti-wave unit can independently float on the sea , even if a section of the breakwater is damaged, the rest can still float on the sea and play a role in resisting the attack of waves. During maintenance, only one or several arc-shaped floating anti-wave units need to be replaced, and the maintenance efficiency is high. Therefore, the present invention overcomes the disadvantages that traditional fixed breakwaters and linear breakwaters are not suitable for deep seas, and has a stable structure and low maintenance costs, and is suitable for deep sea areas with open surroundings, strong wave action and uncertain wave direction.

Detailed ways

The present invention will be further described below in conjunction with drawings and embodiments.

As shown in Figure 1, the present invention includes a circular floating breakwater 1 formed by connecting a plurality of arc-shaped floating anti-wave units 2 with the same radius of curvature to form a closed and stable circular water area for safe operation of ships and facilities at sea 3.

As shown in Figure 2, each arc-shaped floating breakwater unit is a box-type structure made of concrete or anti-corrosion reinforced concrete, and each arc-shaped floating breakwater unit can independently float on the sea surface, Be fixed on the deep-water island reef 5 with anchor chain 4.

After the connection, the water body of the circular floating breakwater 1 and the surrounding circular area 3 floats on the sea as a whole. For shaped floating breakwaters, the anchoring measures for breakwaters may not be considered. Can utilize deep-water island reef etc. as meeting special circumstances, be fixed on the deep-water island reef 5 with facilities such as anchor chain 4, prevent from drifting too much. Due to the small area of deep-water islands and reefs, deep-water islands and reefs can be located in a circular water area surrounded by circular floating breakwaters.

As shown in Figure 3, the adjacent arc-shaped floating breakwater units are connected to each other by tenon joints to form an overall circular floating breakwater, and the two ends of each arc-shaped floating breakwater unit are made The female surface is made into one side, and one side is made into a male surface, which can be conveniently pushed in and installed during construction. In Figure 3, only one surface is drawn for the two arc-shaped floating breakwater units.
