大型多孔连体涵管的微差水压爆破拆除

Demolihing Amulti-orifice Passage By Water-pressure and Millisecond Blasting

介绍了采用水压爆破拆除一大型多孔连体涵管的工程实例。在实施水压爆破拆除时 ,针对涵管长条形结构特点 ,提出了采用多段微差起爆和柱状条形药包等爆破技术以减小震动的方法 ,并在实践中进行大胆探索 。

In this paper, a practical example of demolishinga multi-orifice passage by water-pressure-millisecond blasting and cuboid dynamite was introduced. A subject on reducing blasting vibration by water-pressure-millisecond blasting and cuboid dynamite was put forward .An successful blasting result had been achieved, which provides a new idea for solving the similar engineering problems.
