Another conventional technique for preventing submergence of underground facilities is a self-driven awnership built in a movable overspeed preventing jaw of Registration No. 10-1369391 (Patent Document 2) as shown in FIG. 11. 10-1369391 has a float 20, thousands of waterproof cars 30, several thousands of supporting straps 31 and 32, a packing pad 40 for fixing several thousands of cars, a side waterproof cloth and a fixing pad And is normally installed in the overspeed protection tuck, and when it rains, the rainwater can flow into the water inlet of the float 20 and can operate. However, since the storm surges over the space above the wide float 20 rather than into the narrow water inlet, it is difficult for the septum of Registration No. 10-1369391 to work properly.

12, a plate 100 having an overspeed protection function is attached to a tilting apparatus 200, as shown in FIG. 12, in another prior art 10,162,7972 (Patent Document 3) To prevent infiltration into the underground facility. The cardboard of the above-mentioned Registration No. 10-1627972 can be surely operated by the actuator constituting the tilting apparatus, but the tilting apparatus is complicated and the management of the actuator may be expensive.
