钢混结构大型厂房整体式爆破拆除

INTEGRAL BLASTING DEMOLITION OF A LARGE SCALE REINFORCED CONCRETE STRCTURE WORKSHOP

采用整体式控制爆破拆除方案对华电扬州电厂钢筋混凝土框-排架结构厂房进行了爆破拆除。爆破前,对汽机房、厂房外墙和楼梯进行了预处理。将厂房划分为3个爆区,采用非电多回路网格式爆破网路,依靠东侧锅炉房倒塌施加在西侧锅炉房上的倾覆力矩,有效地克服了西侧锅炉房向西倒的难题,可为同类工程提供一定的参考。

Reinforced concrete frame-bent structure of Yangzhou power plant of Hdadian group was de- molished by using integral control blasting demolition scheme. Steam room, exterior wall and stairs of the workshop were pretreated before blasting. The plant was divided into three blasting zones, and non-elec- tric blasting multi-loop-mesh network was adopted. Relying on the overturning moment on the west boiler room by the east boiler room collapse, the problem of west boiler room collapsed to the west side was ef- fectively overcomed. The method used in this project could have a guiding significance for similar projects.
