Abstract
The invention discloses an emergency flood gate device for a metro tunnel across a river. The emergency flood gate device is a device for emergently closing flood gates mounted at the two ends of the middle river section of a metro across the river according to a program when pipe sheets on the middle river section are damaged and a large amount of river water invades the metro. The emergency flood gate device is especially suitable for closing the tunnel in a total cross-section way when the pipe sheets are naturally or artificially damaged as the metro across the river in a city in our country is more shallowly buried and the pipe sheets of the tunnel are closer to the river bottom so as to prevent a large amount of the river water from invading and paralyzing an urban metro network. Gate valves are arranged in the gates of the device, so that the tunnel can be conveniently and quickly repaired when the metro tunnel is damaged and the water enters the whole tunnel.
