The invention discloses a bridge-used tubular pile and belongs to the field of foundation piles for bridge construction. The bridge-used tubular pile comprises a bracket, a pile column and a jack, wherein the jack is arranged at the top of the pile column; the bracket is arranged at the top of the jack; the pile column comprises a movable rod and a driving part and is divided into an upper segment and a lower segment, and the top of the lower segment sleeves the bottom of the upper segment of the pile column; the movable rod is arranged in the lower segment of the pile column; the driving part is mounted in the upper segment of the pile column and is in contact with one end part of the movable rod; and the driving part is provided with a driving face in contact with the movable rod. According to the bridge-used tubular pile, as the electric jack and the pile column are arranged at the bottom of the bracket, and the electric jack is electrically controlled and connected with a control computer, ascending and descending of the jack can be adjusted in real time according to the stress state of a deck to reduce impact on the pile column under the bridge; and the movable rod in the lower segment of the pile column can extend out when the pressure on the deck is too large to grasp the foundation so as to increase the stability of the bridge.
