Description

Breakwater structure and construction method thereof

The present invention relates to a breakwater structure, and more particularly, to a breakwater structure and a construction method thereof, which is easy to construct and that seawater flows in and out of the inland sea and the open sea.

In general, breakwaters are almost essentially installed in ports or coastal areas, and these breakwaters are installed in various forms and in various construction methods.

Early breakwaters were installed at a height that could block some high waves, and the inner and open seas were blocked along the breakwater construction section. However, when the breakwater is constructed in such a way that the seawater is confined, the seawater on the inland sea side is contaminated because the seawater does not flow smoothly, and various kinds of dirt accumulate, and in severe cases, there is a problem that an odor occurs. Because of this, it is not an exaggeration to say that the tidal flats on the inland sea side or the ecosystem on the seabed are completely destroyed.

Moreover, in the case of the above-described breakwater, a large repulsive force is generated in the seawater hitting the breakwater, and the seawater that strikes in succession is combined to hit the breakwater with greater energy. have.
