采用控制爆破技术拆除钢筋混凝土供水塔

Demolition of Reinforced Concrete Water Supply Tower by Controlled Blasting Technology

笔者从爆破设计、周边建筑物的保护、倾倒方向的选择等,介绍精准定向控制爆破技术在城市高大供水塔拆除中的应用。通过采取的控制爆破技术使爆破振动、倾倒振动、冲击波、飞石等参数均在设计允许范围之内,未对周边建筑物的居民造成影响,取得了良好的社会效益;倒塌的塔身、锥体已变形开裂,能满足机械二次破碎施工要求。

This paper introduces application of controlled blasting technology to demolition of high water supply tower in urban based on blasting design, protection of surrounding buildings and selection of dip direction, etc.. Controlled blasting technology is adopted to make blasting vibration, dumping vibration, shock wave, flying stone and other parameters within the allowable design scope, which has no impact on surrounding buildings and residents and brings good social benefit. The collapsed tower and cone body have deformed and cracked, meeting requirements of secondary mechanical crushing construction.
