Foundation prefabricated PC template

The utility model discloses a foundation prefabricated PC template for foundation pit modeling, which relates to the technical field of building foundation pit modeling and comprises a prefabricated concrete plate and a prefabricated concrete base, the precast concrete slab is of a square structure, frames are integrally machined on the upper edge, the lower edge, the left edge and the right edge of the precast concrete slab, the frames protrude out of the back face of the precast concrete slab and define a soil filling groove, a slab mortise is formed in the top face of the upper frame, and a tenon is arranged on the bottom face of the lower frame. A base mortise is formed in the top edge of the precast concrete base; for a certain prefabricated concrete slab, the tenon can be inserted into the base mortise in a matched mode to form a tongue-and-groove structure, or the tenon can be inserted into the slab mortises of other prefabricated concrete slabs in a matched mode to form a tongue-and-groove structure.
