瑞典发明了一项无炸药岩石爆破新技术,可用于排除施工现场的岩石。该技术基于液压作用原理,首先将油注入专门设计的爆破筒内,然后将爆破筒放进岩石孔洞中,施以700Lb 压力后就可以碎裂掉80%的岩石。液压泵使爆破筒产生的爆发力为60～125t,爆破筒有三种规格。
Sweden invented a new non-explosive rock blasting technology that can be used to exclude rock at the construction site. The technology is based on the principle of hydraulics by first injecting oil into a specially designed blasting cylinder and then placing the blasting cylinder in a rock hole that can break 80% of the rock with 700Lb of pressure. Hydraulic pump blasting cylinder to produce explosive force of 60 ~ 125t, there are three kinds of specifications of the blasting cylinder.
