Abstract

The invention provides a prefabricated assembled hollow pier with transverse partition plates and a construction method, and relates to the technical field of bridge construction. The hollow pier sequentially comprises a foundation, a general section and a top cap section from bottom to top, and foundation connecting steel bars and foundation connecting columns are arranged at the top of the foundation; general section transverse partition plates are arranged at the top and the bottom of the general section, a general section reserved groove is arranged in the general section transverse partition plate located at the bottom, and a general section connecting steel bar is arranged on the general section transverse partition plate located at the top; a top cap section transverse partition plate is arranged at the bottom of the top cap section, and a top cap section reserved groove is formed in the top cap section transverse partition plate at the bottom; during splicing, the connecting steel bars and the connecting columns located on a lower portion extend into the corresponding reserved grooves located on the upper portion, and a high-strength slurry is poured into the reserved grooves; and prestressed pipelines are pre-buried in the foundation, the general section and the top cap section, and connection is performed by penetrating through full-length prestressed tendons. By theadoption of the scheme, a prestress on a pier wall can be flexibly arranged, and manufacturing is easy and convenient.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a prefabricated assembled hollow bridge pier with a transverse diaphragm and a construction method. Background technique [0002] At present, when bridge piers cross large rivers or oceans, the construction conditions are harsh, the wind and waves are strong, the effective time for on-site operations is short, and concrete pouring and maintenance are difficult, which is not suitable for cast-in-place construction. It shortens the on-site working time and improves the project quality; and has strong water transportation and hoisting capabilities, and the pier can be divided into large sections and assembled with large mechanical equipment, which is suitable for hollow pier with high height; in some waters at home and abroad or It has been applied in bridge engineering in sea area. [0003] Hollow bridge piers are often of high height and large cross-sectional size, an...
