The utility model discloses a building bored concrete pile structure, including anchor board, bored concrete pile, supplementary dead lever, sleeve pipe and prestressed anchorage cable, the vertical setting of bored concrete pile, its top is run through the anchor board, supplementary dead lever is connected with the bored concrete pile, and the slope setting of interlocking from top to bottom is in around the bored concrete pile, the sleeve pipe install in on the bored concrete pile, the intraductal atress member that is equipped with of cover, the prestressed anchorage cable connects two supplementary dead lever. Set up supplementary dead lever the bored concrete pile around, can effectively solve and form the problem that tapering and load box easily slope because of mechanical drill bit leads to the fact the wearing and tearing of bored concrete pile bottom, the crisscross supplementary dead lever that sets up simultaneously, reducible cubic metre of earth of excavation and backfill volume, the reduction is to the destruction of ecology, and resources are saved, the prestressed anchorage cable improves the balanced action of supplementary dead lever plays certain guard action to the bored concrete pile, can prevent that the bored concrete pile from bending, squinting, and construction cycle can be shortened in the construction of being more convenient for simultaneously.
