Abstract
PURPOSE: To obviate the negative pressure produced in the cavity at the back by inserting a spoiler into the cavity at the back of the top of a gate body and communicating the cavity with the air through the spoiler.
CONSTITUTION: At the back of a gate body 1 a chute 4 is provided and the inlet port 5 of the chute 4 is made to have an opening at the back of the top 3 of the gate body 1. In the cavity 9 provided in the corner on the downstream side of the back of the top 3, a spoiler 10 is inserted introduce the air whereby the negative pressure produced in the cavity 9 is obviated. In addition, by making the outlet part 12 of the chute 4 opened toward the downstream, the deposited silt near a riverbed part 13 is eliminated.
