广州轨道交通地铁四号线土建第四监理标段的区间五标(除两座跨河大桥之外)至区间九标上部结构为预制混凝土节段箱梁,采用上行式和下行式架桥机整孔拼装架设的施工方案。这项先进的架桥技术在广州地区还是第一次试用,能否达到设计的意想效果,对整个过程的施工监理是至关重要的。通过实践从中得到了一定启发和总结,为今后类似工程的施工监理提供借鉴。
Interval five standard (excluding two bridges across the river) of the fourth civil engineering supervision section of Guangzhou Metro Line 4 to the interval Nine superstructures of the superstructure are prefabricated concrete section box girders with up and down erecting machines Entire hole assembled erection of the construction program. This advanced bridge technology in Guangzhou is still the first trial, the design can achieve the desired effect, the entire process of construction supervision is crucial. Through practice, we got a certain inspiration and conclusion, which will provide reference for construction supervision of similar projects in the future.
