摘要
介绍了桥梁超深嵌岩人工挖孔灌注桩施工中采用的爆破及安全施工技术,重点阐述了采用爆破技术在硬质岩石中进行人工挖孔桩的施工技术,通过实践证明采用爆破技术进行人工挖孔,无论从质量、工期及经济效益方面都是可行的。
It introduces the blasting in hole digging in bridge super deep socketed rock by manual work cast-in-place construction and the .safety construction technology in it, and illustrates the construction technology of applying blasting technology to dig hole in hard rock by manual work. The practice proves that applying blasting technology to dig hole in hard rock by manual work is feasible from quality, construction period and economic benefit.
