人工挖孔桩与钢管桩在流砂地层中的结合应用

The application of the method combined with manual hole digging pile and steel pipe pile in quicksand formation

结合工程概况及其地层概况,提出了采用人工挖孔桩与钢管桩相结合的施工方案,并对其基础设计、桩基检测结果、施工顺序及技术要点进行了阐述,实践证明,该施工方案既缩短了工期,又降低了造价成本,并使整个工程的降差得到了较好的控制,效果良好,值得推广。

Combined with general engineering situations and geological conditions construction scheme combined with manual hole digging pile and steel pipe pile is introduced and discussed from foundation design, pile foundation detection, construction order, technical key points and other aspects. Practice shows this method not only reduce the engineering cost but also shorten the limit time, which is worthy of being popularized.
