With the rapid development of the economy,the load on existing bridges is increasing,leading to frequent occurrence of bridge diseases.Bridge reinforcement is a common method for repairing bridge defects and improving bridge bearing capacity.This study is based on the reinforcement and maintenance projects of four Class Ⅲ bridges,including the Sanjiao Elevated Bridge on the Southeast West Ring Road.A set of pin type track chiseling machines was designed independently,and an adjustable chiseling construction technology was proposed.Through comparative experiments and engineering inspections,this technology has overcome the difficulties of rapid chiseling construction on bridge structural surfaces of different widths,depths,and angles,and combined with chiseling machines to form a complete,efficient,and high-quality chiseling construction process.The adjustable structure chiseling construction technology has wide promotion significance for bridge reinforcement and other structural chiseling construction.
