本文介绍了在复杂环境下30m高钢筋混凝土薄壁水塔的定向控制爆破拆除的工程实例。根据对水塔主要结构分析和保护周围建筑物的要求,合理制定了水塔拆除的爆破设计方案,通过采用毫秒延时爆破技术,有效地控制了爆破振动对临近房屋的影响,可为类似拆除爆破工程提供参考。
This paper introduces the engineering example of directional control blasting demolition of 30m reinforced concrete thin-walled water tower in complex environment. According to the main structure of the water tower analysis and protection of the surrounding buildings, the rational design of the water tower demolition blasting design, through the use of millisecond delay blasting technology to effectively control the impact of blasting vibration near the housing, for similar demolition blasting project for reference.
