预应力混凝土箱梁因具有传力简单、施工工艺成熟、工期短等优点,在桥梁主体结构中被大量采用,现场采用集中预制、吊装。现根据现场施工中的关键环节探讨预应力混凝土箱梁的施工要点,重点分析施工过程中较易忽视的技术问题及其质量进行总结探讨,为类似工程施工提供借鉴供同行参考。
Prestressed concrete box girder has the advantages of simple transmission force, mature construction technology, short construction period, etc., which are widely used in the main structure of the bridge. The site is prefabricated and hoisted centrally. Based on the key aspects of on-site construction, the key points of construction of prestressed concrete box girder are discussed. The technical problems that are easy to be neglected in the construction process and the quality are discussed emphatically, which can provide reference for similar projects.
