Flood resistant building with flood protection and renovation method

摘要

[PROBLEMS] To provide a flood resistant building having a flood barrier that can minimize the influence on the building itself and can provide a safe long-term evacuation life even during floods. SOLUTION: A flood resistant fence 2 is constructed in a site surrounding a building 1 so as to surround substantially the entire periphery of the building 1, and the part connected to the entrance and the other part to be a regular entrance are made watertight. To block the opening, and when there is a risk of flooding due to floods or storm surges, the opening will be closed by the closing means so that a calm space 3 isolated inside the flood barrier 2 can be formed The flood barrier 2 is watertight and has a structure capable of sufficiently resisting hydrostatic pressure and hydrostatic pressure when floods and storm surges occur, and has a strength, and when the surrounding area is flooded at a high inundation depth. In order to enable a long-term evacuation life, an emergency water receiving tank 4 and an emergency generator 5 are installed on the roof of the building 1, etc., and an emergency water tank 6 is installed underground in the site.
