A bridge space radioactive concrete-filled steel tube bridge pier comprises a flange, a plurality of bridge pier bottom stiffening plates, four bridge pier support beams, six tie beam stiffening plates, four pier top anchor plates and a plurality of tie beam stiffening plates. Four mounting positions in even distribution along the circumferential direction are reserved on the top surface of the flange; bottom walls of the four bridge pier support beams are mounted at the four mounting positions on the flange respectively; a tapered space is formed by encircling of the four bridge pier support beams, and the cross section of the tapered space is decreased gradually from top to bottom; one pier top anchor plate is mounted on the top wall of each bridge pier support beam; and a plurality of anchor bolt preformed holes in even distribution are reserved on each pier top anchor plate. A pile foundation of the bridge pier is centralized blow a bearing platform, and occupied urban space is small. Formwork-free pouring of bridge pier concrete pouring is achieved, and the bridge pier is convenient and efficient to construct, safe and rapid, excellent in structural behavior of rod pieces, higher in rigidity of a main beam, good in stability and the like. The invention further relates to a construction method of the bridge space radioactive concrete-filled steel tube bridge pier.
