大直径钻孔桩施工工艺

The construction techniques of bigger-diameter drilling stakes

简单介绍了大孔径、深桩基、复杂地质层钻孔灌注桩施工工艺控制,重点论述气举反循环成孔工艺在深桩基钻孔施工中的应用以及采用旁置式漏斗灌注混凝土施工。

This paper introduces the construction techniques of the bigger-diameter drilling and casting stakes under the conditions of deep stake foundation and complex geological layers, especially in discussing the applications of the air-pump-reverse drilling technique and side-set funnel casting drilling concrete construction.
