摘要
结合在京沪高速铁路天津特大桥钻孔桩的施工经验,阐述了旋挖钻的钻孔原理、钻孔施工工艺、成孔检测和常见的钻孔异常情况的处理,提出旋挖钻机施工的质量控制措施,以期提高旋挖钻机施工质量。
Based on the construction experience of bored piles in Beijing-Shanghai High-Speed Railway Tianjin extra-large bridge,this paper expounds the auger drill from the aspects of drilling principles,construction techniques,pore-forming testing,and common treatment of unusual situations,and puts forward quality control measures for auger drill construction, in hopes of increasing the construction quality of auger drill.
