构皮滩水电站碾压混凝土围堰可利用性爆破拆除施工

Re-utilizable blasting dismantling of RCC cofferdam for construction of Goupitan Hydropower Station

构皮滩水电站下游碾压混凝土围堰爆破拆除是大体积碾压混凝土可利用性爆破拆除,其下部结构作为永久建筑物,需要拆除上部的碾压混凝土。2006年12月10日爆破成功,从安全监测资料与爆破前后的声波检测显示,本次爆破满足设计要求,是一次成功的可利用性爆破拆除。

The blasting dismantling of downstream RCC cofferdam for construction of Goupitan Hydropower Station is a re-utilizable blasting dismantling of mass RCC concrete, So far as the cofferdam is concerned, the lower part of it is to be taken as a permanent structure and the upper part RCC concrete is to be dismantled, On Dec, 10 2006, the cofferdam is successfully blasted, and the data from the safety monitoring and the acoustic detection show that the blasting fully meet the design requirement and is a successful re-utilizable blasting dismantling as well.
