A floodgate system having an automatic floodgate integrated with a cut-off wall is provided to use a concrete structure for a long term by keeping a concrete structure not to be in direct contact with water using a cut-off wall and to protect a salvage floodgate by preventing a counterflow of water using an automatic floodgate. The floodgate system having an automatic floodgate integrated with a cut-off wall contains an outlet formed on the lower part of a concrete structure(1) installed to cut off a drainageway, a salvage floodgate(3) coupled with a winch bar(5) moving vertically by a winch(4) and moved vertically together with the winch bar to open and close the outlet, a cut-off wall(6) installed between a beam(2) and a beam of the concrete structure to protect the front of the concrete structure and composed of a steel plate and a reinforcement member, and an automatic floodgate(7) installed on the lower part of the cut-off wall to be opened forward by the pressure of water passed through the salvage floodgate and made of rubber to increase the sealing capacity of the automatic floodgate. |
