The invention provides a cement fixing device capable of reducing the risk of radioactive solid waste grouting overflowing, and relates to the field of nuclear three-waste treatment, the cement fixing device comprises a stirring system and a pumping system, the stirring system is used for manufacturing slurry, and the pumping system is used for pumping the slurry in the stirring system into a packaging assembly; the pumping system comprises a mortar pump and a screw pump which are arranged in parallel, the mortar pump and the screw pump are communicated with a discharging port of the superior system through a three-way electromagnetic valve, and discharging ports of the mortar pump and the screw pump are communicated with the output pipeline. The influence on the grouting efficiency can be weakened as much as possible while the barrel overflowing risk is reduced, and the adaptability to containers containing different types of radioactive waste is better. 本发明提供一种降低放射性固体废物灌浆冒桶风险的水泥固定装置，涉及核三废处理领域，包括搅拌系统和泵送系统，搅拌
