The invention relates to a bridge prefabricated hollow pier column post-cast connection structure, which is characterized in that the structure includes a prefabricated hollow pier column, a pier column foundation and a post-cast concrete pier wall; the top surface of the pier column foundation is pre-embedded with a connecting steel plate, The center position is provided with an installation limit block to limit the installation position of the prefabricated hollow pier column; the prefabricated hollow pier column is fixed on the pier column foundation through the connecting steel plate; the prefabricated hollow pier column is covered with a steel casing, and the outer wall of the steel casing is provided with Steel ribs; the outer periphery of the bottom of the prefabricated hollow pier column is poured with a concrete pier wall, and the inner hollow position is filled with a concrete core section formed by slightly expanding concrete. The structure involved in the invention has fast construction speed, high connection strength, good overall stress performance and strong earthquake resistance due to the adoption of prefabrication technology, and has better technical and economic benefits. The invention also discloses a construction method for the bridge prefabricated hollow pier column and foundation connection structure.
Description
technical field [0001] The invention relates to a bridge prefabricated hollow pier post-cast connection structure and construction method, which belongs to the field of bridge engineering and is suitable for prefabricated bridge piers and foundation connection projects with tight construction period and high requirements for connection strength and anti-seismic performance. Background technique [0002] At present, the pier structure of urban bridges usually adopts cast-in-place construction, and the road surface needs to be blocked during construction. In addition, the cast-in-place construction period is long, and the construction quality is not easy to control. In addition, the consumption of supports and formwork during construction is large, and the construction cost is high. , and directly affect the road traffic capacity of the construction site, which is incompatible with the requirements of urban construction and development. If the bridge pier is prefabricated in a...
