Drainage roadbed for high underground water level

The utility model relates to a drainage roadbed for a high underground water level, which adopts the methods of prevention, drainage and desludging and can effectively prevent disoperation of underground water on a roadbed. A permeable layer is arranged under a road structure, underground water is drained to blind channels at the two sides through the permeable layer, and a soft permeable pipe is arranged in the blind channels. Water is drained to a collector well through the blind channels and the soft permeable pipe and then is drained into a road rainwater system to be drained away through a drainage horizontal pipe.
