摘要
结合深圳市某基坑工程实例,针对咬合桩施工过程中存在的相关问题,提出了"基坑支护咬合桩长螺旋钻素桩、筒式钻斗旋挖钻荤桩"施工技术。实践表明,本项技术在工程应用中取得了显著成效,具有成孔效率高、成桩质量好、安全可靠、综合成本低等优点。
Based on a foundation excavation engineering practice in Shenzhen,aiming at the related problems existing in the construction process of secant pile,the construction technology of "long auger plain pile for foundation excavation support and barrel drill bucket rotary drill reforced pile"is proposed.Practice shows that this technology has achieved remarkable results in engineering application,and has achieved the advantages of high hole forming efficiency,good pile forming quality,safety and reliability,low comprehensive cost,etc.
