摘要(Abstract):

介绍了用微差水压爆破一次性拆除一个多格容器式钢筋混凝土构筑物的工程实例。文中对药量计算、水中药包位置的确定、微差间隔时间的合理选择、药包的制作以及起爆网路进行了详细的论述 ,并对爆破效果进行了分析。为同类工程的设计和施工提供了可借鉴的经验。
In this paper, an engineering example of once through demolition of a gridiron container reinforced concrete structure by millisecond water pressure blasting is briefly introduced. The calculation of charge weight, the determination of in water charge position, the reasonable selection of delayed interval, charge preparation and priming circuit are expounded and the blasting results analyzed. Some experience used for reference are provided for the design and construction of similar projects.
