Modular prefabricated reinforced concrete hollow pier structure and assembly method thereof

Abstract

The invention discloses a modular prefabricated reinforced concrete hollow pier structure and anassembly method thereof. The structure includes a cast-in-place cushion cap, transverse-assembly pier segments, vertical prestressing bars and assembly cap beams. Each transverse-assembly pier segment includes left and right asymmetric assembly sections, a middle assembly section and a steel bar connector, wherein the left and right asymmetric assembly sections are connected with the middle assembly section through the steel bar connector and finish rolling thread steel. The transverse-assembly piersegments are vertically overlapped with staggered joints and connected with the vertical prestressing bars, and the vertical prestressing bars are tensioned in multiple stages, and the assembly cap beams are divided into several sections and connected through transverse prestressing bars. According to the lifting capacity and construction mode of construction equipment, the height and transverseblock size of the transverse-assembly pier segments can be divided, installation is easy, horizontal and vertical assembly and connection are reliable, construction is convenient, and the transportation and assembling problems of prefabricated components of a modular prefabricated reinforced concrete hollow pier in complex mountainous environment can be solved.

Description

technical field [0001] The invention belongs to the field of bridge engineering, and in particular relates to a modular prefabricated and assembled reinforced concrete hollow bridge pier structure and an assembly method thereof; the invention is suitable for the prefabricated and assembled construction of bridge piers in complex mountainous environments. Background technique [0002] Under the background of the rapid development of today's society, traffic restrictions will indirectly cause huge economic losses. As an important transportation infrastructure, if the bridge is constructed according to the traditional construction method, not only the construction time will be long, the impact on the environment will be great, and the construction quality will not meet the design requirements. Therefore, the use of bridge prefabrication and assembly technology to reduce the impact on traffic, society and the environment, and to ensure the construction quality while increasing t...
