为拓宽城市发展空间,需从一城市建筑密集区修建一条市政道路,该道路从一山腰通过,有大量的石方需要爆破,拟削坡山体陡峭,建筑群依山修建,周围有各种架空管网,爆破环境极其复杂,施工难度大。为加快施工进度,选用弱松动不耦合装药爆破技术,并通过在边坡设置减震孔、调整最小抵抗线的方向、搭设分层防护排架等技术措施,确保了施工安全,取得了很好的爆破效果。 In order to broaden the space for urban development, a municipal road needs to be built from a densely populated urban area. The road passes through a mountainside. There are a large number of stones to be demolished. The mountain to be cut is steep, and the buildings are built on the mountain. There are various overhead Pipe network, blasting the environment is extremely complicated, construction difficult. In order to speed up the construction progress, we choose the loosely loose uncoupled charge blasting technology and ensure the construction safety by setting the shock absorption holes in the slope, adjusting the direction of the minimum resistance line, Good blasting effect.
