DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of a water stopping device for a waterway according to the present invention will be described with reference to FIGS.
Is a gate body, and the gate body 1 is formed in a shape that is detachable from the water channel, that is, smaller than the width of the water channel, and that can be put in and out of the water channel in a state of crossing the water channel. The main body 1 itself is formed so as to be able to stand up.

Here, in order to make the gate main body 1 standable in the water channel, as shown in FIG. 1, the gate main body 1 is formed in a box shape in which a port (not shown) through which water can be supplied and discharged is formed. As shown in FIG. 2, the gate body 1 is formed in a plate shape.
Not only can this be realized by forming a fall prevention support plate S on the downstream surface of the gate, but also the gate body 1 formed in a plate shape can be erected while suspended by heavy equipment. . 2 shows only the gate body 1 and the support plate S, and omits illustrations of rods and the like described below.

Reference numeral 2 denotes a rod rotatably disposed on the outer surface of both side surfaces 3 of the gate body 1. The rod 2 has a length extending from the upper end to the lower end of the gate body 1, and a handle 4 is connected to the upper end of the rod 2.

Numeral 5 is a waterproof rubber plate directly or indirectly connected to the rod 2 via a rubber receiving plate 6.
The water-stopping rubber plate 5 is also formed to have substantially the same length as the rod 2. The water-stopping rubber plate 5 is formed to have such a width that the water-stopping rubber plate 5 is pressed against the side walls 7 of the water channel when the rod 2 is rotated by operating the handle 4 as described above.

Among them, the guide roller 8 has a spherical surface, and the guide rail 9 is disposed in the up-down direction of both side walls 7 of the water channel, and is formed in a tapered shape which becomes lower toward the upstream side of the water channel. The guide roller 8
Basically, one may be provided on each side surface of the gate body 1, but a plurality of them may be provided. Also, the guide rails 9 may be arranged in one row in the vertical direction on both side walls 7 of the water channel, but may be arranged in a plurality of rows. These may be appropriately determined depending on whether the gate body 1 is formed in a box shape or a plate shape.

Reference numeral 10 denotes a protruding plate provided on a part of the rod 2, and reference numeral 11 denotes a stopper protruding from the gate body 1 near the rod 2. That is, the stopper 11 is provided at a position where the protruding plate 10 that rotates with the rotation of the rod 2 abuts.

Thus, the gate body 1 is inserted into a water channel to be used as a water stoppage. In this case, the gate body 1 may be suspended using a heavy machine, and when the gate body 1 is removed from the water channel, the heavy machine may be used for lifting. I just need to. When the gate main body 1 is formed in a plate shape shown in FIG. 2, the gate main body 1 descends against the buoyancy due to its own weight. When water is supplied into the gate main body from an access port (not shown), the weight of the water is added to the weight of the gate main body 1, so that the gate main body 1 gradually descends against buoyancy, and eventually the gate main body 1
When the water reaches the bottom of the channel and the water is discharged, the gate body 1 gradually rises. Also, since the gate body 1 is used for stopping water,
If it is not necessary, it can be removed from the waterway using heavy equipment and used only when necessary.

In any case, before the gate body 1 is inserted into the water channel, the rod 2 is rotated in advance by operating the handle 4 so that the water stopping rubber plate 5 is brought close to the side surface of the gate body 1. I do.

Even when the landing is made in this manner, water is present on the upstream side of the gate body 1, so that the water tends to be pressed on the downstream side of the gate body 1, but the weight of the entire gate body 1 or the shape of a box is taken. In the formed gate main body 1, the movement of the gate main body 1 is prevented by the weight of the gate main body 1 and the weight of the water contained therein, but the gate main body 1 is moved downstream during the lowering process of the gate main body 1. In some cases, the guide roller 8 disposed on the side surface of the gate body 1 abuts on the guide rail 9 when it moves, and further movement is prevented, and the guide rail 9 Since the guide rail 9 is formed on the raper surface as described above, the guide rail 9 functions as a wedge between the both side walls 7 of the water channel and the guide roller 8, and the tapered surface forms the gate body 1 at the center of the water channel. Fix It's also to Mel it.

When the rod 2 is rotated by operating the handle 4, the water-stopping rubber plate 5 is also rotated and pressed against the side walls 7 of the water channel.

In this manner, the water is stopped on both sides of the gate body 1 by the pressure bonding, and at this stage, since the gate body 1 is pressed against the waterway riverbed, the stop provided on the lower surface of the gate body 1 is stopped. The lower surface of the gate body 1 is also stopped by the water rubber plate 5 '. The other parts are stopped by the gate body 1 itself.

Even if the water-stopping rubber plate 5 is pressed against the water channel side walls 7 as described above, the water-stopping rubber plate 5 and / or
When a water pressure is applied to the rubber receiving plate 6 from the upstream side, the water stopping rubber plate 5 or / and /
And the rubber receiving plate 6 can stop water without rotating any more.
