Steel box girder mounting method based on cable-stayed bridge
The invention provides a steel box girder mounting method based on a cable-stayed bridge, and relates to the technical field of bridge construction. According to the method, for a first steel box girder needing to be installed, the first steel box girder is hoisted to a steel box girder support located in a preset area through a first hoisting device; sliding the first steel box girder to a mounting position corresponding to the first steel box girder by utilizing a sliding system on the steel box girder bracket, and connecting the first steel box girder to the mounting position; concrete pouring is conducted on the steel-concrete combined section based on the connected first steel box girder; and after the top of a cable bent tower of the cable-stayed bridge is sealed, the cable bent tower is used for sequentially installing the stay cables connected with the first steel box girder, so that installation of the stay cables of the installed girder section is completed. According to the embodiment of the invention, the installation step of the steel beam box can be moved forward to the top sealing of the cable bent tower and before the construction of the steel-concrete combined section, the construction time is shortened, the construction progress of the cable bent tower is not influenced on the premise of ensuring safety, the overall construction period is shortened, and the construction cost is reduced.
本申请提供了一种基于斜拉桥的钢箱梁安装方法，涉及桥梁施工技术领域。该方法中针对所需安装的第一钢箱梁，利用第一吊装装置将第一钢箱梁吊装至位于预设区域的钢箱梁支架上；利用钢箱梁支架上的滑移系统将第一钢箱梁滑移至第一钢箱梁对应的安装位置，并在该安装位置上连接第一钢箱梁；基于连接后的第一钢箱梁对钢混结合段进行混凝土浇筑；在斜拉桥的索塔封顶后，利用索塔依次安装与第一钢箱梁连接的斜拉索，以完成已安装梁段的斜拉索安装。本申请实施例能够将钢梁箱安装步骤前移至索塔封顶以及钢混结合段施工前，缩减施工时间，并能够在确保安全的前提下不影响索塔施工进度，缩短总体工期，降低施工成本。
