DOCK GATE WITH SMALL FLOODGATE

摘要

A dock gate with a small water gate is provided to reduce the launching time of the complete ship and improve the productivity by mounting the small water gate at the upper side of the dock gate and quickly flowing the injected water into the dock. A dock gate(100) with a small water gate(102) is composed of the small water gate; an opening and closing apparatus longitudinally moving the small water gate; an air tightness member(120) attached at the bonded area of the small water gate and the dock gate to block the intrusion of water; reinforcing members(122) preventing the small water gate from being separated; and a path structure protrusion(130) placed at the front of the opened part of the small water gate to preclude the ship in the dock from being damaged due to the rapid water when opening the small water gate. The reinforcing members are attached at the side of the seawater and at the side of the dock. The opening and closing apparatus is a hydraulic power ram(104).
