Breakwater

Abstract

A breakwater, in which the surface thereof facing the sea (H) is a curved surface rendering the cross section of the breakwater a trapezoid with curved side (ABCDEFG) which comprises a shorter top side (EF), a longer bottom side (AG), and a curved side (ABCDE) facing the sea (H). The curve profile is similar to a recumbent concaved-up parabola.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a tsunami breakwater capable of effectively withstanding the attack of tsunami, storm surge or ocean waves.DESCRIPTION OF THE RELATED ART[0002]Recently, reports on catastrophes caused by the attack of tsunami or storm surge are impressive. For example, causes for tsunami, especially, the catastrophes caused by the Chilean Tsunami and the Indonesian Tsunami are particularly described in detail and vividly in “Climate Change and Natural Disaster” (edited by HUANG Jianmin and XU Zhihua, December 2005, Meteorological Press, Beijing).[0003]Causes of tsunami generally come from the seabed, such as a seabed earthquake, a volcanic eruption or seabed strata movement, and a tsunami may be also caused if meteorites fall into the sea. A tsunami occurs on average once per year, resulting in tremendous losses to human beings.[0004]The tsunami is almost consistent in terms of its current velocity from the sea level to the sea floor.

AI Technical Summary

Benefits of technology

"The invention provides a breakwater that can protect against tsunamis and other sea surges. The breakwater has a curved surface that gradually weakens the force of the waves, reducing the impact force and improving its ability to withstand the waves. The breakwater also acts as a channel for navigation, allowing vessels to enter and exit safely. Additionally, the breakwater can be designed to provide a pleasing and beautiful landscape in coastal cities. The invention also includes a method for protecting a bay by using the breakwater to prevent the tsunami from reaching the vessels within the bay. The curved surface of the breakwater helps to redirect the ocean waves, reducing the impact force and protecting the vessels from damage."

Problems solved by technology

The bay built in this way is not only convenient for vessels to navigate into or out of the bay, but also greatly weakens an impact force caused by the surges at the time when the tsunami arrived due to a reduced channel area through which the ocean waves can get into or out of the bay by the tsunami breakwater, thereby protecting the vessels within the bay from the attack of tsunami.
