Replaceable high-strength prefabricated assembled pier

Abstract

The invention relates to a replaceable high-strength prefabricated assembled pier which comprises a bearing platform, a prefabricated pier column arranged on the bearing platform and a bent cap arranged on the prefabricated pier column. The upper end and the lower end of the prefabricated pier column are fixedly connected with connecting structures embedded in the bearing platform and the bent caprespectively to form a whole. Each connecting structure comprises a sleeve which is embedded in the bearing platform or the bent cap and is provided with an opening in one end, a plurality of fixingblocks are arranged on the inner wall of each sleeve, and a cavity allowing the upper end or the lower end of the prefabricated pier column to be inserted in a matched mode is defined by the inner side surfaces of all the fixing blocks jointly. Compared with the prior art, the structure is light in weight and high in strength, the construction method is simple, operation is convenient, rapid replacement can be achieved for the bridge pier column damaged after an earthquake, traffic can be recovered in time, and the good recovery performance after the earthquake is of great significance in economic development of the society.

Description

technical field [0001] The invention belongs to the technical field of bridge engineering and relates to a replaceable high-strength prefabricated assembled bridge pier. Background technique [0002] In recent years, with the rapid development of my country's transportation infrastructure, especially urban expressways, urban viaducts occupy an important position. The huge construction demand has put forward higher requirements for construction quality and construction efficiency. The construction method of on-site concrete pouring has a long maintenance period. The workload is large, which will have a great impact on the surrounding environment and traffic. At present, more and more concrete bridge components are being manufactured and processed in factories. After the components are manufactured, they are transported to the bridge site for assembly, which greatly reduces on-site operations, speeds up the construction progress, realizes rapid construction, and reduces the imp...
