摘要
随着建筑业机械化程度不断提高,旋挖桩施工技术因其施工效率高、施工成本大幅度节约、施工安全性高等因素逐渐在建筑桩基施工领域得到应用。但是旋挖桩施工技术带来的一系列质量问题却不容小觑,为此重庆市在2011年8月份紧急出台了"关于加强对旋挖桩质量检测"的通知。该文主要针对旋挖桩在重庆山地岩石地质情况下干成孔施工技术及相关质量控制措施进行浅析。
With the growing degree of mechanization in construction industry, construction technology of rotating drill pile is widely applied in the pile foundation construction field because of high efficiency, great reduction of cortstruction cost and high construction security. However, a series of quality problems originated from the technology cannot be ignored. Therefore, notice of＂ on strengthening the quality inspection on rotating drill pile＂ was launched by Chongqing Municipal government in August, 2011. The dry hole-forming construction technology of rotating drill pile under the mountain rock geological condition of Chongqing and relevant quality control measures are analyzed.
