Roadbed electroosmosis drainage device and roadbed

The invention provides a roadbed electroosmosis drainage device, and belongs to the technical field of drainage devices. The device comprises a plurality of electro-osmosis drainage pipes which are located between a fly ash sand cushion layer and a water-resisting layer of a roadbed and used for receiving water flowing into the electro-osmosis drainage pipes from the fly ash sand cushion layer; the electroosmosis drainage pipe comprises a drainage hard pipe and a filtering hose sleeving the upper part of the drainage hard pipe; axial conductive metal is embedded in the pipe wall of the drainage hard pipe, and a plurality of water inlets used for draining accumulated water in the roadbed into the drainage hard pipe are formed close to the upper portion of the pipe wall. The filtering hose is made of a permeable material, the contact part of the filtering hose and the water-resisting layer is hermetically connected, a cavity is formed between the filtering hose and the drainage hard pipe, and a porous filtering
