摘要:
为了降低高耸筒式建筑物爆破拆除时对环境的影响，在千斤顶使用经验积累和木桩换墙定向倒塌技术借鉴的基础上，设计了有孔钢筋混凝土支柱系统，并提出了高耸筒式建筑物破墙换柱绿色爆破拆除技术。技术的特征是：破除高耸筒式建筑物倒塌切口内的筒壁，形成若干门洞，利用有轴向预埋孔的钢筋混凝土支柱支撑系统临时支撑上部结构；再在钢筋混凝土支柱预埋孔中装药并爆破，实现定向倒塌。给出了技术参数、有孔钢筋混凝土支柱支撑系统的设计方法以及施工流程。为凸显新技术的优越性，以复杂环境下某烟囱爆破拆除工程为例，分别设计了新技术和传统钻爆拆除方案，并对比了技术效果与经济成本。结果表明：新技术中，炸药使用量降低了90%，雷管使用量降低了91%，爆破拆除的直接成本降低了18.8%，爆破有害效应大幅降低，施工效率显著提升。因为新器械的使用，新技术比已有的木桩换墙定向倒塌技术倒塌更精确、更安全和更高效；比传统钻孔爆破拆除技术更环保。实现了高耸筒式建筑物爆破拆除技术的升级。
Abstract:
In order to reduce the impact on surrounding environment during blasting demolition of high-rise cylindrical buildings, a perforated reinforced concrete pillar system was designed based on the accumulated experience of using jacks and the reference of directional collapse technology using wooden piles to replace walls. A green blasting demolition technology of wall-breaking and column-replacing for highrise cylindrical buildings was proposed. The cylinder wall inside the collapsed cut of the high-rise cylindrical building is broken to form several doorways. A reinforced concrete pillar support system with axial embedded holes is used to temporarily support the upper structure. Then, charge in the embedded holes of the reinforced concrete pillar and blast to achieve directional collapse. Technical parameters and design methods for perforated reinforced concrete pillar support systems, as well as construction processes, were provided. To highlight the superiority of the new technology, taking a chimney blasting demolition project in a complex environment as an example, the new technology and a traditional drilling and blasting demolition method were designed separately, and the technical outcomes and economic costs were compared. The results show that, in the new technology, the amount of explosives has been reduced by 90%, the amount of detonators has been reduced by 91%, and the direct cost of blasting demolition has been reduced by 18.8%. The harmful effects of blasting have been significantly reduced, and the construction efficiency has been significantly improved. Due to the use of invented tools, compared with the existing directional collapse technology using wooden piles to replace walls, the new technology makes the collapse of buildings and structures more precise, safe, and efficient. It is more environmentally friendly than traditional drilling and blasting demolition techniques. It achieves an upgrade in the blasting demolition technology of high-rise cylindrical buildings.
