Small-clear-distance bailey truss dismantling method
The invention discloses a small-clear-distance bailey truss dismantling method. The method comprises the steps of arranging a monitoring point on the side which is parallel to an explosion source, namely, the explosion facing side of an existing line, and evenly arranging other monitoring points on the front side and the rear side with the monitoring point as the center according to a preset number of pairs; arranging a vibration sensor for acquiring blasting vibration data on each monitoring point; monitoring and analyzing the influence of blasting excavation of the newly-built tunnel on theexisting tunnel according to the blasting vibration data collected by the monitoring points to obtain a vibration sensitive area and a relative safe area in the existing tunnel; and arranging a new monitoring point according to the vibration sensitive area, the relative safe area and the blasting construction progress of the newly-built tunnel. The technical problem that the small clear-distance bailey truss cannot be continuously used after being cut and disassembled in the prior art can be solved.
本申请公开了一种小净距贝雷支架拆除方法。该方法包括：在平行于爆源处既有线迎爆侧布置一个监测点，并以所述监测点为中心，前后两侧以预设对数均匀布置其他的监测点；在每个所述监测点上布置用于采集爆破震动数据的震动传感器；根据所述监测点采集的爆破震动数据对新建隧道爆破开挖对既有隧道的影响进行监测分析，得到所述既有隧道中振动敏感区域和相对安全区域；根据所述振动敏感区域和所述相对安全区域以及所述新建隧道的爆破施工的进度布置新的监测点。本申请可以解决相关技术中小净距贝雷支架切割拆除后无法继续使用的技术问题。
