国内挂篮拼装基本都是采用先拼装再提吊的工艺,而对于具有地形陡峭、桥面高度高以及1#斜拉索设在0#块等特点的梅溪河特大桥,若采用传统施工工艺则要耗用大量的人力、物力,既不经济也不安全,因此该桥采用了高空拼装挂篮施工工艺。本文简要地介绍该桥挂篮在高空拼装的流程,重点介绍高空拼装平台的布设、挂篮第一次拼装、采用挂篮完成0#块混凝土的第二次浇注、以及挂篮在平台上的推移等各项的施工流程以其细节操作。
The basic domestic cradle assembly is to use the first assembled and then lift the crafting process, and for steep topography, the height of the bridge deck and 1 # stay cable located in 0 # block and other characteristics of the Meixi River Bridge, if the traditional construction Technology will consume a lot of manpower and material resources, neither economical nor safe, so the bridge assembled using high-altitude cradle construction technology. This article briefly introduces the bridge hanging basket at high altitude assembly process, focusing on the installation of high-altitude assembly platform, hanging basket for the first time assembly, the use of hanging basket to complete the second 0 # block of concrete pouring, and hanging on the platform Changes and other construction process with its details of the operation.
