抜き用開口を形成することにより、扉体倒伏時に
扉体が内方の浮力によりふらつかないようにした
ものである。Detailed Description of the Invention (Industrial Application Field) The present invention relates to a undulating gate installed in various waterways such as rivers and agricultural waterways, and by forming an air vent opening on the side of the gate body. This prevents the door body from wobbling due to internal buoyancy when the door body is collapsed.
（従来の技術と発明が解決しようとする課題）
従来の起伏式ゲートは、第３図に示すように扉

在に設置して構成されており、計画水位に達する
と、ヒンジ部３ｂを中心に扉体３ａを回転させて
河床３ｃ上に倒伏させるようになつている。(Prior Art and Problems to be Solved by the Invention) A conventional undulating gate is constructed by installing a door body 3a rotatably on a river bed 3c by means of a hinge part 3b, as shown in FIG. When the planned water level is reached, the door body 3a is rotated around the hinge part 3b and is lowered onto the river bed 3c.

なりの水位があると、扉体３ａが浮いて完全に倒
伏できないなどの問題があつた。 However, at that time, there are air bubbles 3 inside the door body 3a.
d, and the buoyant force F caused by the air bubbles 3d causes the door body 3a in the collapsed state to wobble and damage the hinge part 3b.If there is a significant water level in the backwater, that is, on the downstream side, the door body 3a may float and become completely damaged. There were problems such as not being able to lie down.

点があつた。 In order to solve this problem, for example, the door body 3a
It has been proposed and implemented to attach a weight 3e to the inside of the bubble 3d.
It is difficult to completely eliminate the wobbling of the door body 3a due to the buoyant force F, and there are problems such as increased cost.
そこで本発明は、簡単な構成により、扉体倒伏

FIG. 2 is a side view, in which reference numeral 1 denotes a door body, the lower end of which is rotatably installed on a river bed 3 via a hinge portion 2. 4 is an anchor, and 6 is a reinforcing steel pipe provided on the upper part of the door body 1. This steel pipe 6
In order to prevent the door body 1 from wobbling due to overflow water when the door body is collapsed, its wall thickness t is increased and its weight is increased.

れている。 The door body 1 has side walls 6 and 7 erected on both sides of the waterway.
It is rotatably installed between the hinge portions 2 so as to be able to rise and fall freely. A hoisting device 8 is installed at the top of one side wall 6. One side of the door body 1 is connected to a hoisting device 8 by a hoisting wire 9, and by operating the hoisting device 8, the door body 1 (see the chain line in FIG. 2) lying on the riverbed 3 is pulled up. Reference numeral 10 denotes a drainer erected on the upper part of the door body 1. Reference numeral 11 denotes an air vent opening formed directly below the steel pipe 6 on the side surface 12 of the door body, and is formed to vent air from air bubbles 13 generated inside the door body 1.

部２が損傷することはない。 This floating gate is constructed as described above, and when the water level of the waterway reaches the planned water level, an automatic device (not shown) is activated and the gate body 1 is automatically lowered.
The collapsed door body 1 will be submerged in the overflowing water (see the chain line in Figure 2). At that time, air bubbles 13 tend to occur inside the door body 1 while it is being collapsed;
3 is quickly extracted from the air vent opening 11. If the air bubbles 13 are quickly removed in this way,
The door body 1 will not wobble due to the buoyancy of the air bubbles 13 and the hinge portion 2 will not be damaged.
