摘要
为优化深基坑内支撑支护结构的爆破拆除技术及应用,介绍了一种基于轴向布孔的基坑内钢筋混凝土支撑梁爆破拆除技术及其在武汉某项目基坑支撑梁爆破拆除工程中的成功应用,通过采用轴向布孔,孔内敷设导爆索及空气间隔装药等技术措施,降低了爆破危害的强度和影响范围,提高了基坑支撑梁爆破拆除的安全性及拆除效率,为复杂环境下大型深基坑支撑梁爆破拆除提供了技术支撑。
In order to optimize the technology application of explosive demolition of deep foundation pit support- ing structure, the demolition technology of reinforced concrete support beam based on axial hole and the successful application in a foundation pit support beam blasting demolition project was discussed. Through the measures of axial hole, detonating fuse in hole and air deck charge and so on, the intensity and influence range of blasting disaster were reduced, meanwhile, the safety and removal efficiency of blasting demolition of foundation pit support beam were also improved, which provides technical support for the demolition of large deep foundation pit bracing beam under complicated environment.
