水密だけが有効な構成となり、目的が達成できない。By the way, in the floodgate 1 provided in the irrigation canal or the downstream river, the water pressure applied to the door body 5 fluctuates between the upstream side and the downstream side due to water level fluctuations and tidal tides.
There is a case where water pressure is applied to both sides or the side opposite to the side where normal water pressure is applied. Therefore, in the watertight structure of the door body 5 provided in the floodgate 1, in the case of both sides of the door body 5 and the reverse watertight stop water,
The shape of the watertight rubber plate 9 is attached according to the current situation, such as using a Y-shaped cross section or a flat rubber back to back. However, with the above means, workability is poor due to a special shape or a complicated mounting method, and since the structure becomes complicated, there is a possibility that the watertight rubber plate 9 may be turned over or curled up. It is necessary to perform an inspection work to check whether the safety and the lifting operation are reliable. When the conventional P-shaped rubber section is used and the mounting method is the reverse of the normal mounting method, only the reverse watertightness is effective and the object cannot be achieved.

き、信頼性も高まるものである。Next, the operation of the watertight rubber plate 9 with a tongue piece according to the embodiment of the present invention will be described. When the door body 5 is lowered and the sluice gate 1 is closed, the annular portion 9a of the watertight rubber plate 9 with the tongue piece is normally set to 4 at the door stop due to the water pressure from running water from the upstream side.
It is pressed against the opposing wall 4a to be in a watertight state and the upstream side and the downstream side are separated. When the water pressure upstream and downstream reverses due to water level fluctuations and tides, the door body 5 presses the door stop 4 from the downstream side. In this case, watertight rubber plate 9 Katazuki tongue provided on the door 5 side edges, concave side inner arcuate tongues 9c is pressed by the water pressure on the downstream side can be effectively utilized water pressure on the downstream side. Earlier portion of a convex shape (arc) on the outside of the arcuate tongues 9c
Therefore, the convex shape on the outside of the arcuate tongue piece 9c is 4
It is pressed in surface contact with the opposing wall 4a of the doorstop 4 abut the opposing wall 4a. Further , when the water pressure on the downstream side further increases, the inner concave side of the arcuate tongue piece 9c is strongly pressed, and the outer convexity of the arcuate tongue piece 9c becomes even larger in surface contact with the opposing wall 4.
It comes into close contact with a. Further, when the water gate 1 is opened and closed when the water pressure is high, the rubber hardness is increased so that the shape of the arcuate tongue piece 9c becomes stronger against external force.
Since the coated urethane resin reduces the sliding resistance of the watertight rubber plate 9 with a tongue piece , the phenomenon of distortion and curling can be prevented, and the stable operation of the up-and-down movement of the door body 5 can be obtained, and the reliability is also enhanced. is there.

When 12 is fixed and the roller 6 is press-fitted at the lowest position where the door body 5 descends, the water- tightness of the watertight rubber plate 9 with the tongue piece is prevented because the door body 5 is prevented from shaking due to water pressure or running water. Will be improved. In addition, FIG.
As shown in (b), in the sluice 1 in which the door body 5 is slid up and down, guide shoes 13 are provided at both ends of the door body 5, and the pressure support member is provided together with the watertight rubber plate 9 with a tongue piece. 14 are provided. When the sluice gate 1 is closed, with a tongue piece
The watertight rubber plate 9 is pressed against the opposing wall 4a of the door stop 4, but the pressure bearing member 14 is also sandwiched therebetween, so that the watertight rubber plate 9 with the tongue piece is not crushed beyond the limit of this interval. ing. Further, on the side opposite to the watertight rubber plate 9 with the tongue piece of the door body 5, a wedge metal (gap-filling metal) 15a having an acute lower end is provided at the lower portion of the door body 5, and the door strikes corresponding to the wedge metal 15a.

きくする必要がなくなる。As described above, in the invention relating to the watertight rubber plate with tongue according to the first aspect of the invention, the cross-section annular portion,
A tongue composed of a rectangular cross section and an arc tongue in cross section
Since the attached watertight rubber plate is not complicated in shape and can be extruded or the like, it is easy to manufacture, and since the mounting method is the same as that of the conventional one, the door side has a general structure and the construction cost is reduced.
Moreover, the tongue Katazuki watertight rubber plate, when mounted on the door of the sluice a rectangular cross section portion as a base surface, the shape of the cross section arcuate tongues,
Make the rectangular side of the cross section concave so that the front part is wider than the width of the ring cross section.
In addition to making it thin, it is formed to project longer than the radius of the annular section.
The rubber hardness of the circular ring section,
Since the rubber hardness of one piece is increased and it is configured integrally with rubber,
When water pressure is applied from the opposite direction, the cross-section ring section and cross-section
The two points of the arcuate tongue can be smoothly brought into close contact with the opposing wall by utilizing the water pressure, and the reverse watertight state can be achieved by a simple structure. The watertight rubber plate with tongue according to claim 2.
In such invention, the hardness of the cross-sectional arcuate tongues, since normally a larger rubber hardness than the ring portion of the hardness, sectional against reverse pressure
The arcuate tongue does not bend locally, and the tip of the arcuate tongue in cross section can be reliably brought into close contact with the opposing wall.
In the invention according to the watertight rubber plate with tongue according to claim 3,
When the watertight rubber plate with the tongue is attached to the door of the floodgate, the sliding contact with the facing wall of the door contact of the arc-shaped tongue with a cross section and the ring- shaped section that connects to the tongue with a cross section is coated with urethane resin. Moreover, it becomes easy to raise and lower the door body against the water pressure. Further, it is not necessary to increase the size of the drive device for raising and lowering the door body .

Of 2
Watertight with tongues so that the points make contact with the opposite wall of the doorstep
Since the rectangular section of the rubber plate is attached to the edge of the door body, it is possible to prevent the tongue piece having an arcuate section from being curled up or curled up when the door body is moved up and down. Also, if the double-sided and reverse water pressure is applied to the door body, cross-sectional arcuate tongues are pressed from a more inward water pressure,
The tip of the tongue with an arcuate cross section is pressed against the opposing wall of the door stop to improve the watertight state. Further , the watertightness of the door body is increased according to the reverse water pressure, and the reverse watertight water stop is possible.
