A water stop material 18 is attached to the lower end of the door body 3 over the entire length in the horizontal direction of the door body 3, and when the wheel 7 is raised (when the door body 3 is lowered), the water stop material 18 causes the door body 3 and the ground G The gap is surely sealed. The wheel 7 may be lifted completely into the door body 3 so that the lower end portion of the door body 3 is brought into direct contact with the ground G.
FIG. 10 is a cross-sectional view showing a water stop structure at the lower end portion of the door body 3 of the tide door according to another embodiment, which is configured so that the wheel 7 does not move up and down unlike the first embodiment. In this case, in order to seal between the door 3 and the ground G when the door is closed, a step Y is provided on the ground G as shown in FIG. Attach and seal the side face of the door body 3 with the step Y. Then, as shown in FIG. 10B, when the door is opened, the slope 20 is installed to move the vehicle or the like.

  Thus, the wheel 7 does not necessarily need to be movable up and down, but by allowing it to move up and down, the water stop material 18 attached to the lower end of the door body 3 abuts the ground G when closed. Even after closing as shown in FIG. 10, it is not necessary to provide a stepped portion Y on the ground G for sealing as in the case where the wheel 7 protrudes greatly from the lower end portion of the door body 3. Therefore, a vehicle or the like can easily pass through the opening X.

Next, a method for opening and closing the tide door according to the first embodiment will be described.
When closing the door body 3, first, the vertical device 17 is operated to lower the wheel 7. And the lower end part of the wheel 7 is protruded largely below the lower end part of the door body 3. At this time, the water blocking material 18 attached to the lower end portion of the door body 3 is lifted from the ground G.
Next, the door body 3 is pushed and moved so as to close the opening X. At this time, the door body 3 rotates around the vertical axis 4, and the wheel 7 moves while rotating on the rail 10. When the wheel 7 moves on the rail 10, if the ground G is subsidized or uneven, the door body 3 moves up and down. Absorbing at the connecting portion composed of the connecting member 5 and the second connecting member 6 does not apply an extra force to the connecting portion, and does not hinder the opening and closing.
When the door body 3 moves to the closed position, the lifting device 17 is operated to raise the wheel 7. And the water stop material 18 attached to the lower end part of the door body 3 is made to contact the ground G, and the space between the door body 3 and the ground G is sealed.
The same may be done when the door 3 is opened.

The second connecting member 6 is attached to the first connecting member 5 so as to be swingable in the vertical direction with respect to the first connecting member 5. Further, the second connecting member 6 is fixed to the door body 3. By attaching the door body 3 to the gate column body 2 through the vertical shaft 4, the first connection member 5, and the second connection member 6, the door body 3 rotates in the horizontal direction with respect to the gate column body 2. The door body 3 can be opened and closed. Since the door body 3 can swing in the vertical direction with respect to the gate pillar body 2, even if the door body 3 moves up and down due to the unevenness of the ground G, the movement is absorbed by the connection portion to the connection portion. Opening and closing can be performed smoothly without applying extra force.

  Moreover, since the wheel 7 for moving the door body 3 in the width direction is provided at the lower end portion of the door body 3, the door body 3 can be moved while being supported by the wheel 7. Furthermore, since the two wheels 7 are provided along the longitudinal direction, the door body 3 can be stably supported.

  Further, since the protruding piece 5a extending from the first connecting member 5 toward the second connecting member 6 and the protruding piece 6a extending from the second connecting member 6 toward the first connecting member 5 are axially attached, By rotating the protruding piece 6 a of the second connecting member 6 around the axis, the second connecting member 6 can be swung in the vertical direction with respect to the first connecting member 5.

  Further, since the wheel 7 is attached so as to be movable up and down with respect to the door body 3, the wheel 7 is moved down to move the door body 3 at the time of opening and closing, and the wheel 7 is raised after opening and closing to lower the lower end portion of the door body 3. It is possible to seal the gap between the door body 3 and the ground G by bringing the waterstop 18 attached to the ground into contact with the ground G. Therefore, it is not necessary to provide a stepped portion Y on the ground G and seal it as in the case where the wheel 7 protrudes greatly from the lower end of the door 3 even after closing. Therefore, a vehicle or the like can easily pass through the opening X.

  Further, since the steadying member 8 protrudes from the door body 3 toward the vertical shaft 4 so as to sandwich the vertical shaft 4 from the horizontal direction, the door body 3 swings horizontally with respect to the vertical shaft 4 when opening and closing. Can be prevented. It can also withstand the water pressure of seawater that enters after closing.

  Further, since the steadying member 8 protrudes toward the vertical position of the first connecting member 5, it is possible to more stably prevent the door body 3 from shaking in the horizontal direction with respect to the vertical shaft 4. .
