箱形通道无拉杆施工工艺

摘要

根据现场无拉杆施工取得的经验,着重介绍了箱形通道无拉杆施工工序、工艺要求及内外模支撑体系,通过在箱形通道施工中采用无拉杆施工工艺,克服了有拉杆混凝土外观质量存在的工艺性缺陷,为类似工程提供借鉴。%According to the experience in the non-strut construction field,the paper introduces the construction procedures,the craft requirement,the support system of internal and external models,and adopts the non-strut construction craft in the box-like passage to overcome the craft shortage in the outlook quality of strut concrete,so as to provide the reference for similar projects.
