废弃矿坑内复杂条件下塔式起重机施工关键技术

Construction Technology of Tower Crane Under Complex Condition in Abolished Mining Pits

以南京牛首山废弃矿坑中佛顶宫项目建设为背景,介绍了在矿坑内塔式起重机的施工过程,并对其采用的三维激光扫描坑体建模进行塔式起重机平面布置、柔性附着连接技术、安拆技术以及利用原有结构设置塔式起重机基础等技术进行了阐述。有效解决了在矿坑内狭窄空间塔式起重机使用的难题,取得了良好的实施效果。

Based on the engineering practice, this paper introduced the construction process of tower crane in mining pits. The technologies as tower crane arrangement with 3D scanning, flexible connection, installation and demolition technology, tower crane foundation setting are introduced in detail. The problem that tower crane is used in narrow mining pit is solved and good effect is obtained.
