Bridge prefabricated hollow pier column post-poured connecting structure and construction method
The invention relates to a bridge prefabricated hollow pier column post-poured connecting structure. The bridge prefabricated hollow pier column post-poured connecting structure is characterized by comprising a prefabricated hollow pier column, a pier column foundation and a post-poured concrete pier wall, wherein connecting steel plates are pre-buried in the top surface of the pier column foundation, and an installation limiting block limiting the installation position of the prefabricated hollow pier column is arranged at the center of the pier column foundation; the prefabricated hollow pier column is fixed on the pier column foundation through the connecting steel plates; the prefabricated hollow pier column is wrapped by a steel protecting barrel, and a steel rib plate is arranged on the outer wall of the steel protecting barrel; the concrete pier wall is poured on the periphery of the bottom of the prefabricated hollow pier column, and the hollow position in the prefabricated hollow pier column is filled with a concrete filling core section formed by micro-expansion concrete. As the prefabricating process is adopted for the structure, the construction speed is high, connection strength is high, overall stress performance is good, anti-seismic performance is strong, and technological and economical benefits are good. The invention further discloses a construction method for the bridge prefabricated hollow pier column and foundation connecting structure.
