摘要
河曲发电厂在改建过程中,需要拆除一座高40 m的晾水塔。该晾水塔周围环境复杂,距离高压线、地上光缆和居民区只有几米和几十米。针对复杂环境下的晾水塔拆除爆破,详细地论述了爆破方案的选择、爆破缺口的确定、爆破参数的选取、起爆网路的设计,实践证明,设计是成功的,为同类工程提供了一些有益的经验。
A cooling tower with 40 m in height in HEQU power plant needed be demolished in complicate surroundings. In this paper, a blasting plan about the blasting cut size, blasting parameters, blasting network, blasting vibration and safeguard of flying rock is put forward. Meanwhile, the results of the cooling tower are discussed.
