Document Type and Number:
Japanese Patent JP2021107671
Kind Code:
A
Abstract:
To provide a seal structure and an inundation waterproof apparatus applying the same, in which a compression and pressure welding seal state function is maintained over a long period between a lower part and both side parts of a waterproof panel, and a lower skeleton and both side skeletons of an opening to reliably prevent sudden invasion of flowing water from outside and leakage and invasion by high hydrostatic pressure and prevent damage in a traverse blocking inundation waterproof apparatus and a descending blocking inundation waterproof apparatus.SOLUTION: There is provided a seal structure for inundation prevention in which a first layer is ethylene propylene rubber EPDM 401, a second layer is EPT-sealer sealing rubber 402, and a connecting surface of the first layer and the second layer is formed into a wavelike surface and a mountain-and-valley surface, and there is also provided an inundation waterproof apparatus in which both side parts 202 and/or a lower part 203 of a waterproof panel body 201 is mounted to a lower skeleton 101 and both side skeletons 102 of an opening 100 with a tightening handle 300, and the seal structure is arranged at a lower part of the waterproof panel body 201.SELECTED DRAWING: Figure 1
