Gravity type permeable breakwater structure with inner side berthing

The utility model discloses a gravity type permeable breakwater structure with the inner side berthed, which belongs to the technical field of hydraulic structures and comprises a breakwater body caisson, the breakwater body caisson is of a permeable box type structure, a box body is composed of an outer wall, a manger board, a bottom board and an outer toe, the inside of the breakwater body caisson is divided into two symmetrically arranged counterweight bins by an inner wall, and the inner wall of the breakwater body caisson is connected with the manger board. The balance weight filler is backfilled in the middle of the balance weight bin, so that the dike body caisson can be kept stable under the action of waves. The dike body caisson is divided into a zigzag water passing channel by the inner wall, the inner wall of the caisson extends out of a flow guide plate, and incident waves of the open sea enter the harbor through the water passing channel and the flow guide plate. Under the reflection and flip flo
