摘要(Abstract):

在环境比较复杂的居民区,控制爆破拆除了钢筋砼水塔。在周围建筑物及煤气管道、上下水管道环境不利的条件下,精心设计爆破技术参数,精心组织施工;对爆破切口,地下煤气管道及上下水管道进行了有效防护;爆破达到了定向准确、安全、破碎好的效果。
The water tower with thin wall to be demolished was located in residential area and surrounded by lots of buildings in complicated environment. This paper,regarding the surrounding buildings,gas pipe line system and water supply-drainage pipe net,which all were adverse circumstances to the blasting,expounded the carefully designed blasting parameters,well organized construction,and the effective protection measures of blasting cuts,underground gas pipes and water supply-drainage system. The blasting reached good effects in terms of its precise collapsing direction,its safety consideration and fragment size.
