可周转钢格构柱塔吊基础设计与施工

Design and Construction of Turnover Steel Lattice Column Tower Crane Foundation

宁宇家园一期工程基础开挖面积大,基坑支护往往扩至规划红线位置。如果采用外置塔吊,塔吊的覆盖半径往往难以满足施工要求,文章通过格构柱塔吊基础的研究,从而获得结构简单、操作简便,格构柱可重复使用的施工方法,有效保证了质量和安全,节能环保、降低造价。

The foundation excavation area of Ning Yu home lth project is huge , its excavation often extended to the p difficult lanning red line position. But if using an external tower crane, coverage radius of tower crane is always to meet the construction requirements.Thus this paper studies lattice tower crane foundation column to obtain a construction method of simple structure, easy operation and reusable lattice column, effectively ensuring the quality and safety, energy saving and cost reducing.
