铁路桥桥墩台帽的切割爆破拆除

A Cutting Blasting Demolition of the Railway Bridge Pier

介绍了某铁路桥桥墩台帽的切割爆破拆除。结合整个改造工程的特殊性要求,在爆破方案中对爆破部位采取水平和垂直2种不同的布孔方式,来实现切割爆破的目的。同时通过对控制爆破参数、起爆网路和起爆顺序的合理设计,保证了在线路正常运营情况下爆破拆除的顺利实施。

The paper introduces the cutting blasting demolition of a railway bridge pier.With the specialty of the reconstructive engineering,two different arrange patterns of vertical and horizontal holes were aplied to achieve the cutting blasting in the blasting scheme. At same time,by the reasonable design of blasting parameters,blasting network and priming sequence,the implementation of blasting demolition was successfully guaranteed without interrupting the railway's normal working.
