摘要(Abstract):
介绍温州瓯江泵站进水口扩建工程。在不断流的情况下 ,用水下控制爆破拓深、拓宽进水口 ,用周边预裂爆破开挖基础孔。双铁筒围堰的使用 ,确保了基础孔的开挖和浇筑质量。周边孔中钢管药筒的使用 ,保证了基础孔围岩的完整性。文中还介绍了双铁筒围堰和钢管药筒的结构
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
