A method for rapid demolishing of a cement concrete pavement slab and a device there for. The device includes a demolishing vehicle, and the demolishing vehicle includes a base disposed at a bottom of the demolishing vehicle. The first shallow cutting allows first saws to make a minimal cut into the cement concrete pavement, increasing the cutting speed. A second deeper cutting is made on the basis of the grooves cut by the first saws, and although second saws have a larger feed, a cutting thickness of the cement concrete pavement is reduced by the first saws. A third cutting follows the same principle as the previous cuttings.
