| Abstract: | In this paper,an extension project of the water inlet of Ou River Pumping Station in Wenzhou city is introduced Under the condition of not stopping the water supply,underwater controlled blasting is used for extension of the water inlet and peripheral presplit blasting for excavation of foundation pile holes By use of a double iron cartridge cofferdam,the excavating and pouring quality of the foundation pile holes is ensured The integrity of country rocks of the foundation pile holes is retained by used of a steel shell column charge in peripheral blastholes In addition,the structures of the double iron cartridge cofferdam and steel shell column charge are presented |
| Keywords: | Underwater blasting Controlled blasting Peripheral presplit blasting |
