摘要
现阶段特殊环境的基坑岩石开挖方式有爆破技术、静态爆破技术以及液压破碎锤打凿技术等,应用比较普及,但各种技术的使用方向及限制条件不一致,难以满足特殊环境的要求。现分析并总结出一种针对复杂开挖环境、可操作性高、施工成本低、施工工期快速的破岩机械及使用方式,以增加基坑岩石开挖技术的选择空间。
At present,the foundation pit rock excavation methods in special environment include blasting technology,static blasting technology and hydraulic breaker hammering technology. The application is popular,but the use directions and constraints of various technologies are inconsistent,and it is difficult to meet the requirements of special environment. Now we have analyzed and summarized a rock breaking machine and its use mode for complex excavation environment,high operability,low construction cost and fast construction period,so as to increase the selection space of foundation pit rock excavation technology.
