Scope: This document specifies the basic requirements, construction techniques, and control measures for the overall lifting of bridge columns using the column-cutting method. This document is applicable to the construction of bridge column-cutting and overall lifting projects. Main technical content: The "Technical Specifications for Bridge Column-Cutting and Overall Lifting Construction" stipulates the technical requirements for the overall lifting of bridge columns using the column-cutting method. The main contents include: basic requirements; the construction process of bridge column-cutting and overall lifting, including construction preparation (including technical requirements for the reaction force structure system, temporary support, limiting structure system, and bridge structure reinforcement), installation and equipment debugging of the lifting system, column-cutting construction, trial lifting and formal lifting, column connection and reinforcement; and construction control. This standard provides comprehensive and systematic technical guidance for highway bridge column-cutting and overall lifting projects, aiming to improve project quality, ensure construction safety, and promote technological progress in the industry.
