Square three-pile bearing platform with underground water uplift force

The utility model relates to the technical field of buildings, in particular to a square three-pile bearing platform with underground water floating force, which comprises three cast-in-place piles and a bearing platform component, and the bearing platform component comprises a plain concrete cushion layer, stirrups, bearing platform steel bars, raft full-length ribs and a building surface layer. The three-pile bearing platform is made into a square bearing platform, the problem that the water buoyancy borne by all the edges of the bearing platform is different due to the placement direction of the three-edge bearing platform is solved, bearing platform steel bars and raft full-length bars are arranged on the bearing platform to resist the base reaction force and the water buoyancy, and horizontal closed stirrups are arranged in the height range of the bearing platform to resist punching damage caused by the water buoyancy. Therefore, the square three-pile bearing platform not only can meet the bending sheari
