Provided is a heaven roadway floor quick hardening device suitable for traveling of a rubber-tyred vehicle. The heaven roadway floor quick hardening device is laid on a roadway floor which is liable to heave. The hardening device comprises a plurality of segmented steel plates with patterns, the width of the segmented steel plates is equivalent to that of an excavated roadway, and the segmented steel plates are connected into a whole in an end-to-end mode through hook mechanisms in the length direction. The segmented steel plates are connected flexibly so as to effectively adapt to slight heaving deformation of the roadway. When the heaving deformation of the roadway is severe, deflection deformation of the steel plates is severe, and normal transportation of the rubber-tyred vehicle is influenced, the segmented steel plates can be removed, the heaving portion of the roadway is removed through excavation, the disconnected segmented steel plates are connected again after the roadway floor is flattened, roadway floor heaving can be effectively solved, and the rubber-tyred vehicle can work normally.
