格构钢承台式塔吊基础是一种针对超深基坑逆作法工程的施工技术。该组合式基础由钢承台、格构式钢柱及灌注桩组成,将格构柱插入钻孔灌注桩,通过格构柱将塔吊基础平台接至地面标高,在地下室顶板安装塔吊基座等,在土方开挖前即可挖成塔吊安装工作,使得该项施工技术具有施工效率高、安全性能高等优点。
Lattice foundation steel lattice tower crane foundation is a reverse ultra-deep foundation pit construction technology for the project. The combined foundation is composed of a steel cap, a lattice steel column and a pouring pile. The lattice column is inserted into a bored pile, the foundation platform of the tower crane is connected to a ground elevation through a lattice column, and a tower crane base is installed on the basement roof. , Excavation can be done before the earthwork tower crane installation, making the construction technology has the advantages of high construction efficiency, high safety performance.
