As for the watertightness between the side surface (side wall) W and the bottom surface of the gate, as shown in FIG. 11, a plate-shaped rubber (packing) 5 is provided over the entire length of the gate 1 on the upstream side of the bottom surface of the water channel R as shown in FIG. 8), and this rubber 5 is obtained by abutting on the semi-cylindrical portion 1a below the gate 1.
As shown in FIG. 12A, a packing 6 is provided in the length direction of the end surface of the gate 1, and the packing 6 is brought into contact with the side surface W of the water channel.

It is common. In addition, in the above publication,
As shown in FIG. 12B, a packing 7 is provided around the rotating shaft 2 on the end surface of the gate 1, and the packing 7 is brought into contact with the side surface W of the water passage to seal the water.

However, in order to deteriorate the packing and replace it, the rotating shaft 2 portion must be disassembled, and the work is complicated.

As shown in FIG. 12 (b), has an L-shaped cross section, and the entire bent piece 7 a is in contact with the waterway side surface W. Since the water seal by the entire surface contact obtains the pressure contact degree only by the compression deflection in the thickness direction of the packing 7 (7a), the sealing effect is inferior to the pressure contact by the bending deflection (lip effect) of the lip 6a of the packing 6 described above. In addition, it is difficult to follow the change in the gap between the end surface of the gate 1 and the side surface W of the water channel due to the swing of the gate 1, and the sealing performance is likely to deteriorate. Further, the end face of the gate 1 may face the side face W of the waterway obliquely due to the bending of the gate 1 and the twisting at the time of turning (up and down). Cause decline. The deterioration of the sealing property causes water leakage, and this water leakage causes water to enter the machine room D along the rotating shaft 2, resulting in a serious accident.

When maintenance such as replacement is performed due to deterioration, etc., it is necessary to disassemble the portion of the rotating shaft 2 because of the ring shape. The dismantling work is complicated as described above, and the economic loss is large.

Since the end surface of the joint is in contact with the packing 7, the joint strength is weak and water leakage easily occurs from this joint due to deterioration over time.

ル性を得るためである。In order to achieve the above object, the present invention is such that first, the packing in the length direction of the gate end face is continued from the packing around the rotation axis. The reason why they are continuous is to obtain a sealing property between both packings.

グの交換も容易で、経済的効果も大きい。Next, the end of the packing around the rotating shaft is water-tightly adhered to the packing in the length direction of the end face. With the adhesive structure, when the packing is exchanged, the adhesive can be removed by removing the adhesive, and a new one can be attached and the end thereof adhered. That is, it is not necessary to disassemble the rotating shaft portion. This means that the present invention can be applied to an existing gate, the packing can be easily replaced, and the economical effect is great.

安定したシール効果を維持する。At this time, the section Y extends from the length direction of the gate end face to the portion receiving the upstream side water pressure around the gate rotation axis.
It is preferable that the packing has a V-shape, and the portion around the gate rotation axis after that has a V-shaped cross section. The packing having a Y-shaped cross section has a sufficient sealing property against high water pressure, and the packing having a V-shaped cross section has a bending bending (lip effect) of the lip when the bending lip faces the water pressure side.
Similar to the letter-shaped packing, it absorbs the sway when the gate is up and down and maintains a stable sealing effect.

字状のもののような剛性は不要である。The packing having the V-shaped cross section is less expensive to manufacture than the Y-shaped packing and has a high lip effect. This is because the packing having the Y-shaped cross section has a smaller bending margin when one lip bends than when the other lip does not have the other lip (due to the protrusion). By the way,
The cross-section V-shaped packing around the rotation axis does not receive high water pressure on the upstream side, so that it is sufficient to prevent water from splashing when the gate stands up and water from submerging when falling down.
Rigidity is not required.

の現物合わせもし易い。Incidentally, the packing having a V-shaped cross section having a high lip effect is particularly effective in a structure in which the gate is cantilevered as in an embodiment described later. This is because if the bearing is cantilevered, the bearing will wear over time, the gate itself will tilt, and the gap with the side surface of the wall will increase. In addition, it is easy to match the actual product at the time of replacement.

採用し得る。BEST MODE FOR CARRYING OUT THE INVENTION As an embodiment of the present invention,
In an end face of an undulating gate installed in a waterway such as a river, packing is provided around the length direction of the undulating gate and around the gate rotation axis. And is continuous from the end face length direction around the gate rotation axis, and the end portion around the gate rotation axis is watertightly bonded to the length direction portion, and the gate extends from the end face length direction. The portion around the rotation axis up to the portion receiving the water pressure on the upstream side has a Y-shaped cross section, and the portion around the gate rotation axis thereafter has a V-shaped cross section. The Y-shaped cross section packing is a bifurcated lip. Is in contact with the side surface of the water channel, and the packing having a V-shaped cross section has a lip that bends outward around the rotation axis is in contact with the side surface of the water channel, and both ends in the longitudinal direction of the packing having the V-shaped cross section have a Y-shaped section. Shaped packing It may adopt a configuration that is watertight glued to grayed.

採用し得る。With this configuration, the above-mentioned sealing effect of the Y-shaped cross section packing and the above-described effect of the V-shaped cross section packing can be obtained. Moreover, since the two packings in the end face length direction and a part of the rotation shaft are separated, the packings can be replaced smoothly as described above. The reason why the Y-shaped cross section packing is subjected to the upstream side water pressure is that the Y-shaped cross section packing has excellent sealing properties, and therefore an effective sealing effect can be obtained even on the upstream side where the water pressure is high. However, as long as an effective sealing effect can be obtained, the position where the packing having the Y-shaped cross section reaches is arbitrary, and the packing around the rotation axis may have the V-shaped cross section. Even in the end face length direction,
Instead of the Y-shaped cross section packing, a V-shaped cross section packing can be adopted.
