Building pile for constructional engineering

The utility model relates to the technical field of building piles, in particular to a building pile for constructional engineering, which comprises a building pile body, the building pile body is of a hollow structure, a conical head convenient for the building pile body to enter the ground is fixedly arranged at the bottom end of the building pile body, a plurality of circular holes are formed in the inner wall of the building pile body, every four circular holes form a group, and a plurality of holes are formed in the inner wall of the building pile body. Each set of circular holes are formed in the inner wall of the building pile body in a circumferential array mode, positioning cones are arranged on the inner walls of the circular holes in a sliding mode, and a driving assembly used for driving each set of positioning cones to extend outwards at the same time is arranged in the building pile body. By arranging the driving assembly, in the actual installation process of the building pile, the positioning
