Novel double-layer arch annular breast wall breakwater

The utility model relates to the technical field of breakwaters. The utility model relates to a breakwater, in particular to a novel double-layer arch annular breast wall breakwater. Bottom plate, anarched inner wall is fixedly arranged at the top of the bottom plate; an arched outer wall is arranged on the arched outer side of the arched inner wall, a plurality of wave dissipation holes are equidistantly formed in the arched inner wall and the outer wall of the arched outer wall, a wave dissipation chamber is arranged on the arched inner side of the arched inner wall, an annular breast wallis arranged in the wave dissipation chamber, a top water diversion plate is fixedly arranged at the top of the inner wall of the arched inner wall, and a bottom drainage plate is fixedly arranged. Thewave absorbing device is remarkable in wave absorbing and energy dissipating, small in wave bearing force and good in stability; breakwater surface wave force passes through the circle center, and overturning moment is not gen
