采用拆除爆破技术拆除既有房屋和构筑物 ,是一种安全快速、经济可行的施工方法 ,在旧城改造和工厂扩建中的应用越来越广泛。爆破的设计必须紧密结合欲拆除对象的形状、结构、材质及其周围环境的特点 ,才能达到预期的效果。文章通过实例 ,介绍单层排架爆破结构失稳状态分析、有关爆破参数的确定、起爆网路的设计以及爆破施工及安全防护等内容 ,为拆除类似结构房屋提供了参考
Demolition blasting demolition of existing houses and structures, is a safe and fast, economical and feasible construction methods, in the transformation of the old city and the expansion of the factory is more and more widely used. The design of the blasting must be closely combined with the shape, structure, material and the characteristics of the surrounding environment of the object to be demolished so as to achieve the expected result. In this paper, an example is given to introduce the instability analysis of the single-layer frame blasting structure, the determination of the blasting parameters, the design of the detonating network, the construction of the blasting and the safety protection, which provides a reference for the demolition of similar structure houses
