移动式承载索应用于特大桥吊装工程的设计

Design of Movable Skyline Hoisting Cableway Used in Unusually Large Bridge

根据架空索道设计的特点及要求,本着技术先进、经济合理和安全适用的原则,创造性采用可移动式承载索,对泉三高速公路下岸特大桥吊装索道进行设计,包括索道选线、索道总体布置、承载索与工作索设计、锚桩的验算。在特定的地形地质条件下,进行有效合理的索道布局,以及主要技术参数的选择,并进行校核。索道在特大桥施工中安全适用,能满足吊装作业和高强度工作量要求。

As one of the most convenient and economical tools of transportation and crane,ropeway begin to use in a variety of building and construction. According to the characteristic and requirements of cableway design,the movable skyline hoisting cableway in Quansan Highway Xia’an Unusually Bridge was creatively designed with the principle of advanced technology,reasonable economy,safety and appliance,which included the general arrangement of cableways, calculation of skyline and workline,checking computation of the support and the anchorage,productivity calculation. Under the specific topography condition,the effective and reasonable layout of hoisting cableway and the main technical parameter properly were chosed,and the calculation was checked. The result showed that the hoisting cableway was safety and appliance in the construction of bridge,and it was suitable in the request of hoisting working and high strength workload.
