摘要
结合高速公路小半径匝道桥预制梁架设实践,分析了既有架桥机改装的可行性,介绍了预制梁架设的关键工艺和操作要点,明确了相应的安全技术措施,有效解决了较大横纵坡条件下公路小半径桥梁的架设难题,为类似工程提供借鉴。
Combined with the practice of highway small radius ramp bridge precast beam erection, the paper analyzes the feasibility of key technology and operating points precast beam erection and makes clear the safety technical measures to solve the difficulties of highway small radius bridge erections, and provide references for similar projects.
