BLASTING DEMOLITION OF GUANGONG STATUE IN ZHAOQING CITY

肇庆关公像是违规建筑,结构复杂,为3层基础结构,钢筋混凝土基础,内部槽钢支撑、外部紫铜。有关部门要求限期拆除,施工期限紧,施工难度大。采用大的梯形爆破切口,预处理切割支撑槽钢,爆破拆除承重部件,利用延时爆破将建筑物成功爆破拆除。

Guangong statue in Zhaoqing city was illegal building. It was of complicated structure with three layers reinforced concrete base, channel steel support inside and red copper outside. The statue was required to dismantle in short time, so its constructive time was short and constructive difficult was large. The solution was as follow： cutting the channel steel by pre-processing, demolishing the supporting parts by large trapezoidal blasting cut, adopting a short-delay blasting. Demolition blasting of Guangong statue was achieved successfully.
