“滑移施工平台法”施工技术脚手架工作量小,占地少,但对滑移轨道下的地基承载力要求高,对目前新机组正在施工、原有机组尚在运行的技改项目,该方案具有一定的优势,对其他条件下的大跨度钢网架施工也有很强的借鉴意义. “Slip construction platform ” construction technology Scaffolding workload is small, less land, but the bearing capacity of the ground under the slip track requirements are high, the new unit is currently under construction, the original unit is still running technical transformation projects The scheme has certain advantages and is also of great reference to the construction of large-span steel truss under other conditions.
