Energy-gathered charging device for blasting demolition of thick steel structure workshop and blasting method
The invention provides an energy-gathered charging device for blasting demolition of a thick steel structure workshop and a blasting method. An explosive energy gathering box is arranged in a manner that an opening is upward, a detonator wire passing hole is formed in the explosive energy gathering box, and a detonating detonator is installed at the position of the detonator wire passing hole; an energy gathering box cover extends in the front-back direction, the section perpendicular to the front-back direction is arranged in an arc shape, the convex face of the energy gathering box cover faces the explosive energy gathering box and is installed on the explosive energy gathering box, and the concave face of the energy gathering box cover is used for being opposite to the fracture face of a steel column body; and the strength of the explosive energy gathering box is not lower than the strength of a steel plate of the steel column body of the steel structure workshop, and the thickness of the explosive energy gathering box is not smaller than the reserved thickness of the steel column body of the steel structure workshop after gas cutting. According to the technical scheme, the energy-gathered charging device and the blasting method have the beneficial effects that the blasting effect which cannot be achieved by a common energy gathering explosive bag can be easily achieved, the to-be-demolished thick steel structure workshop is smoothly completed, harmful blast waves of blasting can be reduced, the explosive utilization rate is increased, the construction cost is reduced, and the environment-friendly benefits are obvious.
本发明提供一种厚钢结构厂房爆破拆除的聚能装药装置和爆破方法，炸药聚能盒呈开口向上设置，炸药聚能盒上开设有雷管导线通过孔，雷管导线通过孔处安装起爆雷管；聚能盒盖沿前后向延伸，在与前后向相垂直的截面上呈圆弧形设置，聚能盒盖的凸面朝向炸药聚能盒，安装于炸药聚能盒上，聚能盒盖的凹面用于与钢柱体断裂面相对；炸药聚能盒的强度不低于钢结构厂房的钢柱体的钢板强度，炸药聚能盒的厚度不小于钢结构厂房的钢柱体气割后的预留厚度。本发明提出的技术方案的有益效果是：可轻松实现普通聚能药包不能达到的爆破效果，顺利完成待拆除厚钢结构厂房，可减小爆炸有害冲击波、提高炸药利用率、降低施工成本，环保效益明显。
