Abstract

The invention relates to the technical field of bridge engineering, and discloses a self-resetting prefabricated assembled pier and a construction method thereof. The self-resetting prefabricated assembled pier comprises a prefabricated pier column and a foundation platform and further comprises prestressed tendons and energy dissipation connecting pieces; the prefabricated pier column and the foundation platform are connected into a whole through the prestressed tendons, one end of each prestressed tendon is used for anchoring a carrying structure at the top of the prefabricated pier column,and the other end anchors the foundation platform. The energy dissipation connecting pieces are connected with the bottoms of the prefabricated pier columns and the foundation platform. The assembledpier is simple in structure, convenient to operate and high in construction efficiency, the constructed assembled pier has self-resetting performance and good overturning resistance, the problem thatpier corner parts of existing assembled piers are prone to damage and breakage due to stress concentration is effectively solved, and the damaged parts are easy to repair.

Description

technical field [0001] The invention relates to the technical field of bridge engineering, in particular to a self-resetting prefabricated assembled bridge pier and a construction method thereof. Background technique [0002] In recent years, transportation infrastructure, especially high-speed railways, expressways and urban expressways, has developed rapidly, among which bridge engineering plays a pivotal role. The huge construction demand puts forward higher requirements on the construction quality and construction efficiency of bridge engineering. With its standardized and modular construction method, prefabricated assembly structure can significantly improve construction efficiency, ensure construction quality, and has the advantages of less interference to existing traffic, green, and environmental protection, so it has been widely promoted and applied, and is very suitable for bridge engineering construction. [0003] At present, in terms of the application of prefa...
