以重庆某大型综合体项目45 m跨度三角形钢管桁架结构安装为例,针对施工场地特殊、吊装设备偏小的实际施工条件,经综合考虑,采用了“滑移胎架+塔吊精确定位吊装”的施工方法,并从工艺原理和关键技术流程角度,对施工方案进行了详细阐述。经实践,该技术安全可靠,可为类似工程参考借鉴。 Taking a 45 m-span triangular steel pipe truss structure installation of a large-scale complex project in Chongqing as an example, aiming at the practical construction conditions of special construction site and small hoisting equipment, the “skating tire rack + tower crane precise positioning and lifting” "Construction methods, and from the process principle and key technical process point of view, the construction plan for a detailed description. After practice, the technology is safe and reliable, and can be used as a reference for similar projects.
