摘要(Abstract):

利用水压爆破拆除了处于复杂环境下的一个大型钢筋混凝土煤气柜。为了控制柜壁的坍塌方向和范围 ,采取了一系列的技术措施 ,这些措施包括增加底层布药量、降低药包整体布置高度、减少总药量、靠近壁体分散布置药包以及控制不同方向炸高等。文中分析了工程难点 ,介绍了爆破方案设计、爆破参数选择以及安全措施等 ,并简述了爆破效果
A large scale reinforced concrete gas tank in complicated environmental conditions was demolished by use of the water pressure blasting In order to control the direction and range of tank wall collapsing,a series of technological measures were taken These measures include proper increase of charge weight at the bottom layer,lowering of the overall height of charge layout,reduction of total charge weight,scattering layout of charges near the wall of the gas tank and control of blasting height in different directions In this paper,the difficult points in present project were analyzed,the design of blasting scheme,the selection of blasting parameters,the safety precautions and others introduced and the blasting results outlined
