摘要
阐述了一种新型托换桩型———微型钻孔嵌岩钢管灌注桩的施工工艺 ,设备及其设计 ,经过一系列工程的应用 ,验证了其具有单桩竖向承载力高、施工简便、质量可靠、施工时引起被托换结构的附加下沉微小等优点 ,具有广泛的适用性及推广价值。
This paper introduces a new underpinned pile-small size bore hole steel tube cast in place pile embeded in rock including its construction technology,facilities and design.By the application in many projects,this kind of pile shows many advantages such as high bearing load capacity,simple construction,reliable quality,and at the same time only cause small additional settlement during construction.It has extensive adaptability and high worth.
