Segmental precast assembled pier and construction method thereof

Abstract

The invention discloses a segmental precast assembled pier and a construction method thereof. The pier comprises a pier main body, a cover beam and a bearing table; the pier body comprises multiple segments, the position, close to the side face, of each segment is provided with multiple reserved hole ways surrounding by a circle, stress main ribs are arranged in the reserved hole ways, hole way outer side stirrups surrounding by a circle are arranged on the side face of each segment, a positioning shear key is arranged on each segment, the cover beam and the corresponding segments form bondinglayers through epoxy adhesive or bedding mortar, the bearing table and the corresponding segments form bonding layers through epoxy adhesive or bedding mortar, and two adjacent segments form bondinglayers through epoxy adhesive or bedding mortar, and positioning shear keys, multiple reserved hole ways and grouting pipelines are formed in the positions, corresponding to the corresponding segments, of the bearing table. During construction, the bearing table is built firstly, the shear keys, the reserved hole ways, the grouting pipelines and the bonding layers are arranged, then, segments aremounted in sequence, and finally grouting is carried out. According to the site lifting capacity and transport capacity, a pier precast segment is divided.

Description

technical field [0001] The invention relates to the technical field of bridge pier construction, in particular to a segmented prefabricated assembled bridge pier and a construction method thereof. Background technique [0002] In the existing technology, the prefabricated bridge structure has good social and economic benefits because it can speed up construction, reduce the impact on environmental traffic, and reduce dangerous operations such as high-altitude operations. [0003] However, in practical applications, due to the limitation of on-site hoisting equipment and transportation capacity, prefabricated bridge piers are urgently needed to expand the application range of fabricated bridge piers. [0004] Therefore, how to reduce the weight of prefabricated bridge piers has become an urgent technical problem to be solved by those skilled in the art. Contents of the invention [0005] In view of the above-mentioned defects of the prior art, the present invention provide...
