Discussion on Application of Rotary Drilling in High Strength Rock Foundation Construction |
| |
| Abstract: | In the large diameter bored piles construction of the bridge with high strength rock foundation, the popularized use of the advanced construc-tion technology of rotary drilling has produced significant benefits. The technical performance and characteristics of rotary drilling rig are elaborated, and the problems in the construction are analyzed and summarized. Combined with the double line bridge construction cases in Gaojiahuayuan, Chongqing, some corresponding countermeasures are presented for similar projects. |
