The invention provides a loose dam body grouting reinforcing structure, and relates to the field of dam body grouting, the loose dam body grouting reinforcing structure comprises a grouted masonry dam body, a gallery is arranged at the bottom end of the grouted masonry dam body, drainage holes are formed in the grouted masonry dam body, and the drainage holes are arranged from top to bottom from the top of the grouted masonry dam body; the bottoms of the drainage holes are communicated with the concrete surface layer on the top of the gallery, and an original concrete anti-seepage panel is arranged on the upstream of the masonry dam body. According to the loose dam body grouting reinforcing structure, through the arrangement of the anti-blocking mechanism, before grouting operation, the opening end of an inflation column penetrates through a thin seam and then is turned over to be arranged on the outer wall of a cylindrical block in a sleeving mode, a rubber ring tightly hoops the turned-over opening of the i
