Abstract
PURPOSE: In a water gate door for enabling passage of ships and adjustment of water levels on the upstream and downstream sides of a river by use of a water gate chamber provided with pull-up tipe first and second gates, to enable reduction of the open-close operation time of the gates.
CONSTITUTION: A water gate 1 comprises a water gate chamber 4 consisting of a front door chamber 2 and a rear door chamber 3, and the passage of ships is enables by operating first and second gates 6 and 7 upwardly and downwardly movably provided in the chambers 2 and 3 respectively. The gates 6 and 7 are set in the open condition by slightly elevating the gates 6 and 7 until the water levels inside and outside the chamber 4 become nearly equal to each other and then rapidly pulling up the gates 6 and 7. The gates 6 and 7 are set in the closed condition by rapidly lowering the gates 6 and 7 to a position close to the bottom and then slowly lowering the gates 6 and 7 to the closed condition.
