Abstract

PURPOSE: To stabilize the flow of water on the gate side and lengthen the life of a rubber seal by providing a projection on both sides of a gate lip in a sluice door of a high pressure in such a manner as to almost vertically cross it with the corner of an effluent pipe at all times.
CONSTITUTION: The main gate 3 as a sluice door provided on the downstream side of an effluent pipe 2 provided to a dam body, etc., is closely contacted under pressure with a rubber seat 5 attached to the periphery of the outlet side end of the effluent pipe 2. In this case, circular auxiliary lips 8 are projectionally provided to both sides of the gate lip 3a of the main gate 3, where the curvature radius r of the gate lip 3 is equalized with the r of the corner of the effluent pipe 2, the center O is positioned at the intersection between the horizontal gate lip 3a and the extended portion of the side edge of the effluent pipe 2, and the corner of the effluent pipe 2 is almost vertically crossed with the auxiliary gate lip 8 at all times.
