PURPOSE: A lower discharge water gate used as a bridge is provided to inspect and repair the water gate easily by crossing a river or passing along the water gate, and to extend a life span of the water gate by distributing stress on a water gate fixing portion. CONSTITUTION: Both girders(1) are connected by a pedestrian beam(2), and a water gate(3) is turned and fastened to the pedestrian beam. Insertion grooves(13,13a) are formed in upper parts(12,12a) of the girders, and both ends of the beam are placed in the insertion grooves of the girders. Bearing fixing parts(22,22a,22b) are formed in the beam to mount an oilless bearing in a shaft hole for inserting a fixing shaft(4), and shaft fixing parts(31,31a,31b,31c) are formed in the water gate. The bearing fixing parts are inserted to the shaft fixing parts, and shaft holes(30,30a,30b,30c) are formed in the shaft fixing parts to insert the fixing shaft. The water gate is turned and fastened by penetrating the shaft fixing parts and the bearing fixing parts with the fixing shaft.
