1976年枝柳线马颈均车站采用深孔爆破新技术,石方工程实现综合机械化施工。该车站利用铁道部武汉工程机械工厂生产的YQ-100B型潜孔钻机钻凿6～12米的深孔(孔径100毫米),并采用毫秒爆破等新技术,保证岩石爆破后块度适宜,然后进行挖、装、运、填机械联合作业。图为马颈(土幻)车站1号工地一次深孔爆破爆花形成的连续过
In 1976 Zhiliu line horse neck are station deep hole blasting new technology, stone engineering to achieve comprehensive mechanization construction. The station uses the YQ-100B DTH drilling rig produced by the Wuhan Construction Machinery Factory of the Ministry of Railways to drill deep holes (100 mm in diameter) of 6 to 12 meters and adopt new technologies such as millisecond blasting to ensure that the block size after rock blasting is appropriate and then To dig, loading, transportation, filling machinery joint operations. The picture shows the neck (soil magic) Station 1, a deep-hole blasting popcorn formed a continuous over
