VENTILATION HOLE FLOODING PREVENTION DEVICE
To solve the problem of being unable to cope with a ventilation hole of a housing foundation due to being limited to the main entrance periphery in coping by a sandbag, though coping with flood disaster damage in underfloor flooding time by normally stacking the sandbags around a residence.SOLUTION: The present invention is provided with a ventilation hole flooding prevention device capable of blocking up in an underfloor ventilation hole. A door body 4 exists in the device, and blocks up the ventilation hole by floating up by pressure of water flowed in the device and a buoyancy material 8. The blocked-up door body 4 completely stops the inflow of water by a double structure of a close contact seal 2 and a close contact seal 5 by water pressure and an expansion seal 6 and a seal pipe 3 by the water pressure.SELECTED DRAWING: Figure 2
【課題】床下浸水時における水害被害に対して、通常住居回りに土嚢を積んで対応していたが、土嚢での対応では玄関周辺に限られ住宅基礎の換気口に対応出来ない。【解決手段】本発明は、床下換気口に閉塞できる換気口浸水防止装置を設ける。装置内には扉体４があり、装置内に流入した水の圧力と浮力材８で浮き上がり換気口を閉塞する。閉塞した扉体４は水圧による密着シール２および密着シール５と水圧による膨張シール６およびシールパイプ３の２重構造で水の流入を完全に止める。【選択図】図２
