爆破作业禁区桩基水磨钻施工技术研究

Research on Blasting Operation Forbidden Zone Pile Foundation Water Mill Drilling Construction Technique

针对特殊地区地段桩基施工不能采用爆破工艺的实际情况,因地制宜,结合地形地质等,采用水磨钻法进行施工,发挥出了该技术的成孔精度高、扩孔系数小、环境影响小、噪音低、安全性高、经济性好等优点,很好地促进了工程建设。

Pile foundation construction in special areas could not use the actual situation of blasting process,adjust measures to local conditions,the water mill drilling method is carried on the construction combined with geology,which makes good use of advantages,such as the high accuracy of forming holes,the small coefficient of enlarged oblonghole,the advantages of low environmental impact,low noise,high safety and good economy have promoted engineering construction.
