宽幅预应力钢筋混凝土混合梁钢筋混凝土结合段“挂篮+支架”组合施工技术

Combination Construction of Width Prestressing Reinforced Concrete Composite Beam Joint Section “Hanging Basket + Holder”

钢箱梁与混凝土箱梁的连接是混合梁大桥的关键点,本文以中兴路北延跨秦淮新河主桥钢筋混凝土结合段施工为例,重点论述钢筋混凝土结合段钢箱梁挂篮结合支架施工以及吊装定位及无收缩混凝土浇筑等工艺,全面介绍梁拱组合桥钢筋混凝土结合段施工技术,为类似工程提供借鉴。

Steel box girder and the connection of concrete box girder is key point of composite beam bridge. This paper takes Zhongxing northbound across Qinhuai Xinhe Main Bridge,reinforced concrete construction as an example,discusses concrete combined with period of steel box girder construction technique of combined with stent and hoisting position and no shrinkage concrete pouring process,comprehensive introduction beam arch combination bridge of reinforced concrete construction technology,to provide reference for similar projects.
