The application of digital detonators energy control system on demolition blasting of TGP′s Ⅲ-phase upstream RCC cofferdam was introduced in this present paper.
本文介绍了i-konTM数码雷管起爆系统在三峡三期碾压混凝土围堰拆除爆破中的应用情况。
The scale,total charge,technique and operated difficulty of the demolition of the third-stage upstream RCC cofferdam all exceed those of the implemented cofferdam demolition at home and abroad.
三峡工程三期上游碾压混凝土围堰拆除的规模、总装药量及技术与施工难度均超过国内外已实施的围堰拆除,因爆破紧邻主体建筑物,为确保建筑物的安全,通过理论分析与模型试验,选取了以“倾倒为主,炸碎为辅”的拆除方案,由于爆破水深,为确保倾倒缺口的形成,由我国国内企业自主研制并使用了高威力、高抗水型的混装炸药,同时为防止爆破振动叠加,首次从国外引进了数码雷管实施控制爆破。
