| Abstract: | Auger drill is a widely used drilling machine in recent years of the cast-in-situ pile construction.Auger drill has the advantages of high efficiency,energy saving,low noise,no pollution and wide stratum adaptation,and has been gradually adopted and applied by various construction units to the construction of pile foundation.As an example of the auger drill construction of pile foundation of the north approach of Chongqing Yongchuan Changjiang River in the shale geology,the article sets forth the technology and application of auger drill for pile foundation drilling in mudstone geology,which can be referred for the similar projects. |
