The present invention relates to a dry dock for preventing inflow of tideland mud and, more specifically, to a dry dock for preventing inflow of tideland mud comprising a dock housing formed to be dented to a regular depth from the ground lower than the sea level and having a set inner space; a dock gate opening or closing the inner space of the dock housing with respect to the sea; a sea water flowing path formed in the underground of the dock gate for the the inner space of the dock housing to be opened to the sea; and a pump installed on the sea water flowing path, wherein the dock gate has at least one penetrated hole and a cover opening or closing the penetrated hole. The present invention can prevent the inflow of the tideland mud included in the sea water inputted into the dry dock via a lower drainage tank when a ship is launched, thereby saving costs consumed in manpower and equipment needed for cleaning the dry dock and collecting the tideland mud. Additionally, the present invention can drain the sea water and immediately perform follow-up processes, thereby reducing overall shipbuilding process time. Moreover, the present invention can reduce usage of the pump by half, thereby saving usage of power and costs consumed in the usage of power. |
