带副拱中承式菱形变截面钢管混凝土系杆拱桥主拱肋安装技术
Installation Technology for Main Arch Rib of a Concrete-filled Steel Tubular Half-through Tied-arch Bridge with Vice Arch and Rhombic Variable Cross-section
摘要
Abstract
This paper was based on the construction of main bridge of the Wuhu Yuanze Bridge, the first one in China in the form of concrete-filled steel tubular half-through tied-arch bridge with vice arch and rhombic variable cross-section. This paper expounded the installation technology of the main arch rib of this bridge, mainly including how to install the main arch rib, how to design the cable crane and buckling-anchoring system, how to design the support frame used in section A of the arch rib, how to erect the work platforms, how to achieve measurement and controlling, how to adopt welding standard and mounting dimension standard, etc. , so as to provide reference for similar projects.关键词
