浅谈浅孔微差控制爆破技术在路基施工中的应用

国高珠环线广东中山沙溪至月环段K89+250~K92+537段路基爆破点离居民房屋最近距离仅60~80m,必须严格控制爆破震动和飞石,确保民居房屋不受爆破震动和飞石的危害。结合工程实例,讨论浅孔微差控制爆破技术的施工控制要点,与有关工程建设同行探讨。

Application of Shallow hole Millisecond Controlled Blasting Technology on Subgrade Construction

As the shortest points of K89 ＋ 250 - K92 an, blasting vibration and distance is only 60 ~ 80m between local residential buildings and the subgrade bursting ＋ 537.5 of Shaxi-Yuehuan Section of the National Pearl River Delta Ring Expressway flying rocks must be strictly controlled in order to prevent local residential buildings from being damaged by blasting amples, the construction control brifely introduced. vibration and flying rocks. In this article, being combined with engineering exkeypoints of the shallow hole millisecond controlled blasting technology has been
