PURPOSE: A sliding type watertight door for a seawall is provided to cut off waves when the surface of the sea is increased by closing an entrance of a seawall. CONSTITUTION: A sliding type watertight door for a seawall comprises a weir(10), frames(21), a guiderail(22), a hanger unit, a position sensor, a light sensor, a lamp, and a track support rail. The weir is slid to/from a seawall(20) to open and close an entrance of the seawall. The frames are fixed to both ends of the seawall and connect the weir and the seawall together. The guiderail is formed in a groove(11) of the weir and guides the sliding of the weir. When the weir closes the entrance of the seawall, the hanger unit is hung on the hook portion of the weir. The position sensor senses the position of the weir when the weir closes the entrance of the seawall. The light sensor senses the lighting of the lamp. The track support rail guides the sliding of the weir and supports the weir. |
