【摘要】：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。
[Abstract]:In view of the actual situation that the blasting technology can not be used in the pile foundation construction in the special area, according to the local conditions and combining with the topography and geology, the water grinding drilling method is used to carry out the construction. The technology has the advantages of high hole forming precision, small hole expansion coefficient and small environmental influence. The advantages of low noise, high safety and good economy have promoted engineering construction well.
