At this time, the support frame 1 and the first stopper 8 A predetermined fastening allowance δ is provided in advance. Then, after the waterproof plate 2 is disposed on the waterproof device installation portion 204, the bottom side seal member 11 provides adhesion with the digging 205 by tightening the bolt 12 </ b> B and the nut 12 </ b> N. Thereby, since the bottom side seal member 11 can further improve the water tightness with the digging 205, higher safety can be ensured.

  FIG. 8 is an explanatory view showing a modification of the locking means used when the waterproof device according to this embodiment is used. In this example, a first stopper 8 ′ that is attached to the passage side wall 202 and fixes the support frame 1 when the waterproof device 100 is used is used as the locking means. The support frame 1 includes a claw 30 that engages with the first stopper 8 ′ and a spring 31 that applies a biasing force to the claw 30 toward the first stopper 8 ′. Here, the claw 30 is attached to the support frame 1 by the support means 32 and is supported so as to be swingable around the support means 32. When the waterproof device 100 is used, the engaging portion 30C of the claw 30 is engaged with the first stopper 8 ′ by the biasing force applied by the spring 31. With such a configuration, the support frame 1 and the first stopper 8 ′ are fixed only by pushing down the support frame 1, and therefore the support frame 1 can be easily fixed.

  As shown in FIG. 1, after the waterproof plate 2 is installed, the waterproof plate 2 prevents water from entering the passage 200, so the space on the underground facility side partitioned by the waterproof plate 2 is a waterproof compartment. Also works. In the waterproof device 100 according to this embodiment, after the waterproof plate 2 is installed, the waterproof plate 2 is used as an overpass for the waterproof plate 2 for the convenience of a person temporarily evacuating into the waterproof compartment from the outside where the water has increased. Transportation devices are provided on the front surface (water W side) and rear surface (underground facility side) of the plate 2. In this embodiment, a front side step 6 is provided on the front surface of the waterproof board 2 as a traffic device, and a rear side step 5 is provided on the rear face of the waterproof board 2. This facilitates evacuation into the waterproof compartment.

  In addition, if the water level is so high that the water level is expected to exceed the waterproof plate 2, the boat is laid on the waterproof plate 2 and the person evacuated to the space on the underground facility side partitioned by the waterproof plate 2 is rescued. It is also assumed that In such a case, the transportation apparatus has an advantage in that it is possible to save the person who has evacuated to the space on the underground facility side partitioned by the waterproof board 2 to the boat laid on the waterproof board 2. There is also.

  In the waterproof device 100 according to this embodiment, since the waterproof plate 2 is stored near the passage ceiling 201 in the normal state, the front and rear spaces of the waterproof plate 2 have a relatively large margin. Therefore, the front side step 6 and the rear side step 5 can be fixed. Accordingly, it is possible to save the trouble of taking out the storage member after installing the waterproof board and attaching the parts stored separately, which is particularly advantageous in an emergency.

  Since the waterproof device 100 according to this embodiment stores the waterproof plate 2 close to the passage ceiling 201 in a normal state, the upper space can be used effectively. At this time, the lower surface of the support frame 1 (the portion that is on the lower side in the vertical direction when the waterproof device 100 is used) is in the air (eg, FIG. 2). Therefore, the advertisement board 7 can be attached to this portion and used for various advertisements. The advertisement fee obtained by soliciting advertisement postings can be used for collecting the installation cost and maintenance cost of the waterproof device 100.

  FIG. 9 is a partial plan view showing an example of a mounting structure of a waterproof plate provided in the waterproof device according to this embodiment. Both ends of the waterproof plate 2 are supported by the two support frames 1. A beam 13 is provided between the two support frames, and a plurality of support columns 14 are arranged in a truss shape between the beam 13 and the waterproof plate 2. Thereby, since the deflection | deviation when the waterproof board 2 receives the water pressure P can be suppressed, the adhesion defect of the side part side sealing member 10 and the channel | path side wall 202 resulting from the said deflection | deviation can be suppressed. Thereby, even when the water pressure P is applied, the water tightness can be maintained, so that high safety can be ensured.

  FIG. 10 is an explanatory diagram showing an example in which the side seal member is movable. In this waterproof board 2 ′, the side seal member 10 is movable. The side seal member 10 is attached to the base 10 </ b> B and is connected to the push member 16 via the connecting rod 15. An elliptical handle 17 is provided between the two push members 16. When the handle 17 is rotated in the direction of the arrow r in FIG. 10, the pushing member 16 is pushed out to the outside of the waterproof board 2 ′ (on the side of the passage side wall 202). This movement is transmitted to the connecting rod 15 and the base 10B, and the side seal member 10 is pushed out to the passage side wall 202 side. When the handle 17 is rotated in the direction opposite to the arrow r in FIG. 10, the side seal member 10 is drawn into the inner side of the waterproof board 2 ′.

  After the waterproof board 2 ′ is installed, the side portion side sealing member 10 is brought into close contact with the passage side wall 202 by rotating the handle 17 in the direction of the arrow r in FIG. According to this configuration, the adhesion force of the side seal member 10 can be adjusted by adjusting the rotation angle of the handle 17, so that, for example, when the side seal member 10 is deteriorated with age and the elastic force is weakened. Also, the side seal member 10 can be pressed against the passage side wall 202 with a predetermined adhesion force. As a result, watertightness can be ensured even when the side seal member 10 has deteriorated over time. Further, when the waterproof plate 2 ′ is installed, if the side seal member 10 is pulled into the inside of the waterproof plate 2 ′, contact between the side seal member 10 and the passage side wall 202 can be avoided. 2 'installation work can be performed smoothly.

  As described above, in the waterproof device according to this embodiment, the waterproof plate (waterproof member) is stored in a normal state by effectively utilizing the space existing in the upper part of the passage that does not hinder the passage of pedestrians. As a result, there is little fear of loss (insufficient number of components) during use. Moreover, in the warehouse (separate location) storage method, the labor and labor of carrying the waterproof plate is not required, but in this embodiment, the labor and labor are not required, so the worker's aging countermeasure and less physical strength are required. Suitable for workers (woman) measures.

  In this embodiment, since the waterproof device can be visually inspected in a state where the waterproof device is stored in the upper section of the passage in normal times, the waterproof device is stored in another place (hangar) or stored under the road surface. Compared with a method such as a method in which the waterproof device is not easily noticed on a daily basis, daily inspection is easier and high reliability of the performance of the waterproof device can be maintained.

  Furthermore, in this embodiment, since the waterproof device is attached using the side wall of the passage to and from the underground facility, etc., it is necessary to perform civil engineering work such as digging under the road surface or digging for installation of continuous columns. do not do. As a result, construction can be easily performed and construction costs can be reduced. Note that the configuration disclosed in this embodiment can be appropriately applied to the following embodiments. Moreover, what has the structure similar to the structure disclosed by this embodiment has an effect | action and effect similar to this embodiment.

(Embodiment 2)
The second embodiment has substantially the same configuration as that of the first embodiment, but the end opposite to the grounding side of the waterproof plate is directed toward the non-immersed side, that is, the inside of the passage, with respect to the horizontal plane of the water that is flooded. In this way, the waterproof board is inclined. Other configurations are the same as those of the first embodiment.

  FIG. 11 is an overall configuration diagram illustrating the configuration of the waterproof device according to the second embodiment. FIG. 12 is an explanatory diagram illustrating a configuration of a waterproof plate included in the waterproof device according to the second embodiment. In the waterproof device 100a, a waterproof plate 2a is attached to one end of the support frame 1a, and a counterweight 3 is attached to the other end so as to balance the waterproof plate 2 with the waterproof device support 4 as a center. With the configuration as described above, the waterproof plate 2a is pivotably supported by the waterproof device support 4 via the support frame 1a with the waterproof device support 4 as a center.

  As shown in FIGS. 11 and 12, when the waterproof device 100 a is in use, the waterproof plate 2 a is lowered to the waterproof device installation unit 204 and the waterproof plate 2 a is installed on the waterproof device installation unit 204.
