description The utility model relates to the technical field of soft rock roadway floor heave supporting, in particular to a broken surrounding rock roadway floor heave treatment supporting structure. The utility model discloses a broken surrounding rock roadway floor heave treatment supporting structure which comprises a reinforced concrete inverted arch which is located below a roadway and is of an arch structure. The foot anchor rods are located at the two ends of the reinforced concrete inverted arch. Grouting anchor rod hole guide pipes and grouting anchor cable bundle guide pipes are arranged in the middle of the reinforced concrete inverted arch in a staggered manner; a grouting anchor rod is installed in the grouting anchor rod guide pipe, and a grouting anchor cable bundle is installed in the grouting anchor cable bundle guide pipe. The structure is easy to machine, low in cost, good in product quality, high in precision, high in bottom plate pore-forming rate and large in supporting area, and the phenomena of g
