Claims

[Scope of utility model registration request]

(1) In the water-stop elastomer outer skin of the water-stop part that surrounds the periphery of the gate, the drain port and the tube are placed on the inner surface of the tube at the drain port part of the tube inserted in the space inside the elastomer. A water-stop elastomer for use in a dam gate, characterized by having a passage communicating with the upper and lower tubes, and having a protruding support that prevents contact between the upper and lower tubes.

(2) For a dam gate according to claim 1, wherein the support for preventing contact is a cap-shaped rigid support having a communication hole provided on the inner surface of the tube at the tip of the drainage pipe. Water-stop elastomer.

(3) The support that prevents contact is an elastomer block provided on the inner surface of the tube around the drain port of the tube, which has a through hole communicating with the drain port in the center and a groove extending outward from the center. A water-stop elastomer for dam gates according to claim 1 of the utility model registration claim.
