摘要:
拟拆除90 m钢筋混凝土烟囱位于宝鸡市区，周边环境复杂，采用单向倒塌控制爆破拆除。分析并确定了烟囱爆破切口的形状、尺寸、爆破参数、起爆网路和爆破安全技术。为了减少炸药用量和减小爆破振动危害，对爆破切口进行预处理。在烟囱倒塌轴线两侧的待爆左右板块中部预先对称开凿1.2~1.5 m宽的缺口，并将烟囱出灰口的门框拆除，割断门框的钢筋，形成宽2.4 m的窗口。复式簇联网路的应用有效提高了网路的准爆性，保证了爆破工作的可靠性。采用开挖减振沟、设置缓冲土垫层等措施降低爆破振动。爆破效果表明，确定的相关参数与安全措施合理有效，保证了邻近建筑物及设施的安全。
Abstract:
A 90m-high reinforced concrete chimney to be demolished was in the downtown area of Baoji City where the surrounding environment is complicated. Directional control blasting was adopted. Shape and size of the chimney blasting cut, blasting parameters, blasting network and blasting safety technology were analyzed and determined. Pretreatment of blasting incision was carried out to reduce explosive dosage and damage of blasting vibration. The 1.2-1.5 m wide gap was pre-cut at the center part of plates symmetrically located at both sides of the collapsed axis. The ash door frame of the chimney was removed by cutting off its steel bar to form a window 2.4 min width. Application of multiple cluster blasting networks has effectively improved the accuracy of blasting network and ensured the reliability of blasting work. Trench and cushion layers were used in blasting vibration control. Blasting effects show that the relevant parameters and safety measures are reasonable and effective, and the safety of adjacent buildings and facilities has been ensured.
