Orifice sealing grouting device

The orifice sealing grouting device comprises an orifice pipe, and a fixed grouting structure is installed on the orifice pipe. The fixed grouting structure comprises a mounting plate, a pair of mounting bases, a pair of drivers, a pair of supports, a pair of sealing gaskets, a grouting assembly and a pair of arc-shaped fixing plates. The utility model relates to the technical field of rock-soil construction, and has the beneficial effects that: through a fixed grouting structure, the problems that when a covering layer and a stratum are broken and a hole wall is not flat and smooth enough, a grouting plug is often not easy to close tightly, and if a steep dip angle crack in a rock develops and grouting is carried out, grout is easy to return around the plug, so that accidents in the hole are caused, and the construction efficiency is low are solved; the grouting effect and the curtain grouting quality are affected by the grouting middle section due to the fact that the grouting effect and the curtain groutin
