Foundation pit slope assembly type supporting device

The utility model relates to the technical field of building deep foundation pit slope protection, in particular to a foundation pit slope assembly type supporting device which comprises a slope, soil nails, positioning clamps and a surface layer, the surface layer is laid on the slope, and a plurality of through holes used for inserting grouting pipes are evenly formed in the slope; the pavement surface of the surface layer and the slope are fixed, so that the surface layer can be stably supported, after construction is completed, the surface layer can be recycled and reused, the support is assembled, construction is green, the soil body exposure time can be greatly shortened, the foundation pit risk is greatly reduced, and the surface layer can be repeatedly used in the later period. Compared with a traditional steel bar net spraying surface layer, the steel bar net spraying surface layer is low in energy consumption and small in pollution, saves materials such as cement, is green, energy-saving and environ
