| Abstract: | The excavation speed of pilot shaft is one of the key difficulties for the excavation of shaft, high ones in special, of hydropower works. Application of inverse well drill will permit quick and safe excavation of pilot shaft Combined with the practice of diversion shaft construction for Zhouning hydropower plant, the application of inverse well drill in construction of pilot well is demonstrated with a detailed introduction on the procedure, method and effect of construction. |
