Building pile for building construction

According to the building pile for building construction, during construction, the pile body is placed in a hole in the ground, downward force is applied to the pile bearing platform, the tamping column is pressed into an inner cavity of the pile body, in the process, the lower end of the tamping column makes contact with and extrudes the top faces of the left limiting block and the right limiting block, and therefore the left limiting block is pushed to move leftwards, and the right limiting block is pushed to move rightwards; the left end of the left reinforcing rod and the right end of the right reinforcing rod extend out of the side wall of the pile body and then are transversely connected with the ground in an inserted mode, meanwhile, the left anti-disengaging rod and the right anti-disengaging rod move downwards and are vertically connected with the ground in an inserted mode, and after installation is completed, concrete can be poured into the inner cavity through a pouring hole and enters the inner c
