The utility model discloses a novel combination formula breakwater, including submerged breakwater and pile foundation open breakwater, towards the wave, the outside is located to the submerged breakwater, and pile foundation open breakwater locates the inboard, and pile foundation open breakwater is equipped with the manger board towards one side of submerged breakwater, and the manger board stretches into the aquatic. Compared with the prior art, the beneficial effects of the utility model are that: bilayer through submerged breakwater and the manger board wave that disappears has overcome that submerged breakwater wave absorbing effect is not good easily to take place the shortcoming destroyed with pile foundation open breakwater, simple structure, and the medium depth of water of specially adapted and dark than the shallow water, sea area that ambient condition is abominable, the unrestrained situation that disappears more corresponds to reality to play better wave absorbing effect, the stability in waters in the assurance port.
