预应力混凝土大跨连续刚构桥施工技术
摘要
东普特大桥是广州市外环线高速公路上的一座特大型重点桥梁。大桥全长1093.5米,为双向六车道单层桥,左右线分离式结构。该桥基础为Ф1.5米、Ф2.0米挖孔桩,上部结构为连续刚构,桥墩采用双薄壁墩,边墩采用柱式墩。该桥施工特点是深水基础、跨径大。本文全面总结了东普特大桥施工技术:详细叙述了大型临时设施的布置、钢护筒打拔及定位技术、基桩检测技术、深水承台施工、箱梁施工及斜拉式、垂直式挂篮的设计及应用等一系列施工技术与成果,对同类型桥梁施工具有参考价值。
Dongpu SuperLange Bridge ,with total length of 1093.5m ,double-direction six-lane sigle layer, separated between the up direction and the down direction ,is the key one of super large bridges of Guangzhou outside ring expressway. The foundation of the bridge is the dug pile with the diameter of 1.5-2.5m,the superstructure is the continuous rigid frame,double thin-walls pier is adopted as the pier of the bridge ,the column pier as the side pier. The construction characteristic of the bridge is that the foundation is under the deep water and the span is larger.the paper sums up the construction technique of dongpu super large bridge all-sidedle and gives the detailed account of a series of construction technique and achievements such as: layout of large-type temporary facilities, The orientation, striking and draw technique of the steel protection cylinder ,the testing technique of the cast-in place pile, the construction of the deep water base salab, the construction of the box beam, the design and practice of cable-stayed and vertical hanging basket etc,which is of the referenced value for the construction of the same type bridge.
