The invention discloses a prefabricated assembled hollow
pier based on UHPC joints and a construction method of the
pier, the prefabricated assembled hollow
pier comprises a pier column and a base, the pier column is a hollow pier column, the pier column is sequentially composed of a pier bottom section, a middle section and a
top cap section from bottom to top, the pier bottom section is located at the top of the base,
steel bar connectors are embedded between the pier bottom section and the base, between the pier bottom section and the middle section and between the middle section and the
top cap section, reinforcing stirrups are arranged outside the
steel bar connectors, and connection is achieved through post-pouring of UHPC joints. According to the invention, the
steel bar connectors between the sections are easy to position and connect, the height of the joints is remarkably reduced, and the using amount of joint concrete is small; the segment construction tolerance is large, and the precision requirement is low; joints are free of vibration, self-compaction is achieved, pouring is convenient, and construction is simple; and the assembled pier is excellent in overall performance, high in joint durability, rapid to assemble, short in field
operation time and high in efficiency.
