摘要(Abstract):
采用水压爆破技术对大型复杂结构钢筋混凝土水池实施爆破拆除,方法简单、施工速度快、爆破效果理想、防尘效果显著,非常适合各级防火场所。本工程将结构复杂的4个大型隔油池分别隔挡成9个相互独立的区域,其中的中心区D区不蓄水,从而使每个待爆隔油池成为一个“回”字形水槽,使其满足水压爆破的基本条件;同时,还采取了四段毫秒爆破和开挖减震沟的两种降振措施。对于如此大型的水压爆破工程是属于比较成功的实例,文章还总结了成功与不足之处。
Water pressure blasting technique has several advantages,like its simplicity in operating method,fast construction,ideal blasting and visible dust-proof effect,and its adaptability to fire alerting locations,when employed in blasting demolition of water pond in large reinforced concrete structure.The paper introduced the process of separating four large size oil separating pond with complicated constructed into nine independent sections,leaving the section D in the center to be the one with no water stored,forming a circular gutter for the execution of water pressure blows-up.Besides,two other measures as 4 delays in MSEL and shock absorption gutter were adopted to reduce shock speed.The paper also summarized the merits and demerits of this technique.
