Abstract

The invention discloses a fabricated pier and a construction process thereof. The assembly type pier comprises a plurality of tubular piles, a bearing platform, a pier column and a cover beam. The tubular piles are arranged at the lower end of the bearing platform and connected with the bearing platform, the lower ends of the piers are mounted in pier positioning grooves in the upper end surface of the bearing platform, and the upper end and the cover beam are connected, prefabricated assembly is adopted in the construction process, all parts of the fabricated pier are prefabricated, and spliced, installed and constructed in parallel after being prefabricated, the construction period is greatly shortened, the influence of construction on the surrounding environment is improved, the appearance quality and the entity quality of engineering are improved, and the fabricated pier has the advantages of being high in standardization degree in the construction process, good in cost control effect and high in construction quality.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to an assembled bridge pier and a construction process thereof. Background technique [0002] The prefabricated assembled concrete main girder technology was gradually developed after the Second World War. After more than 70 years of development, the shear key structure of inter-segmental joints, close-fitting prefabrication, external prestressing technology and construction technology development, The construction technology of prefabricated and assembled concrete girders is becoming more and more mature; the prefabricated and assembled technology of concrete bridge piers has a history of more than 30 years abroad. Viaducts; subsequently built a number of bridge projects with substructures using prefabricated assembly technology; in 1965, the first main girder of Henan Wuling Weihe Bridge (T-shaped rigid frame bridge) was constructed using prefabricated cantilever as...
