京沪高速铁路附近钢筋混凝土支撑梁爆破拆除

对位于在建京沪高速铁路附近的梁厂内的钢筋混凝土支撑梁进行了爆破拆除。为了减小爆破振动、爆破飞石等爆破危害,采用孔内孔外延时起爆网路,严格控制一段最大起爆药量。本次爆破拆除获得成功,取得了理想的爆破效果,可为类似工程提供参考。

BLASTING DEMOLITION OF REINFORCED CONCRETE BRACE BEAMS NEAR BEIJING-SHANGHAI HIGH-SPEED RAILWAY

Reinforced concrete brace beams were demolished by blasting in the beam plant near Beijing-Shanghai high-speed railway which was being constructed.For minimizing blasting risks caused produced by blasting vibration and blasting sky rocks and so on,the initiation network of out hole and in hole delay time was adopted,and the maximum amount of explosive detonated at one time was controlled strictly.The blasting demolition of the project was successful and reached desired blasting effect.Its successful experience can be used as reference by similar project.
