Holing caisson permeable breakwater with holing slope baffles designed in energy dissipation chambers

Abstract

The invention belongs to the technical field of ocean and provides a holing caisson permeable breakwater with holing slope baffles designed in energy dissipation chambers. The holing caisson permeablebreakwater comprises a caisson and a wave stop wall. Holing partition walls are arranged in the caisson, so that a plurality of divisions are formed. The outer wall of the upper portion of the caisson is provided with caisson holes, the divisions obtained after holing of the caisson serve as the energy dissipation chambers, and other divisions of the caisson except the energy dissipation chambersare filled with sand. The holing slope baffles are arranged in the energy dissipation chambers. The wave stop wall is arranged on the tops of the energy dissipation chambers. According to the permeable breakwater, kinetic energy of waves is utilized to dissipate energy, wave loads borne by the structure are reduced, secondary reflection of the waves in a harbor is reduced, and the wave height behind the breakwater is reduced; the upper portions are holed and permeable, water bodies inside and outside the harbor can be exchanged, and the breakwater is environmentally friendly to zoology; the lower portion is impermeable, and silt can be stopped from entering the harbor; and the structure gravity center is low, and the stability of the breakwater is improved.

Description

technical field [0001] The invention belongs to the technical field of marine technology, and relates to a permeable breakwater, in particular to a perforated caisson permeable breakwater with perforated oblique baffles designed in an energy-dissipating interior. Background technique [0002] With the development of society, the advancement of science and technology, and the increasing prosperity of international trade, marine engineering is also constantly developing in deep water. Traditional forms of breakwaters such as slope dikes and vertical dikes have many shortcomings in the face of these changes, such as the sharp increase in cost as the water depth increases, the difficulty of construction increases, the construction period is longer, and it is not suitable for soft soil foundations; in addition, in recent years, marine ecology The construction of civilization is strengthened. In order to build a blue bay, the shortcomings of the traditional breakwater's impermeabi...

AI Technical Summary

Problems solved by technology

However, due to the air-permeable characteristics of this kind of structure, especially under the action of long-period waves, more energy transmitted will increase the wave height in the port and affect the stability of mooring conditions in the port; and it cannot prevent sediment from entering the port. Therefore, it is still difficult to widely use it as a permanent anti-wave facility

In addition, the lower supporting structure of the permeable breakwater bears most of the loads on the structure, and its own safety and stability will be seriously threatened in extreme environments
