摘要
桥梁施工缆机占压的桥头岩质路基,紧邻桥台新浇筑砼、500kV输电线和崖下沿河公路等重要建筑。为满足工期要求,采取了分区多梯段大规模微差松动爆破技术,并加强安全防护措施,使桥台砼安全控制和飞石、滚石控制均获成功。
The subgrade at the end of Xialaoxi bridge was occupied by a cable machine,next to some important buildings,such as bridge abutment and a 500kV transmission line.To meet the requirement of construction schedule,different techniques of blasting benches were adopted in different district,and meanwhile,safety control was also strengthened in the blasting operation.The blasting successfully made the bridge abutment and the flyrocks or fragments under control.
