摘要
杭州第二长途电信枢纽楼工程位于钱塘江边 ,地质条件复杂 ,单桩承载力高 ,施工中采用了 S5 0 0钻机成孔、气举反循环清孔和压密注浆等方法 ,保证了工程质量。
The second telecommunication pivot building of hangzhou is located near qiantang river. Its geological conditions are very complex and the bearing ability per pile is high. In the construction of pile foundation, some methods such as pile\|making with S500 drill machine, reverse circulation bore clearing with compressed air and grouting at bottom, an so on were adopted to ensure the construction quality.
