以广州地铁二、八号线沙园站-凤凰新村站区间施工竖井为例,对城市地铁施工竖井钻爆法施工作一总结。考虑爆破震动对临近建筑物的影响及防止爆破飞石对过往行人和车辆造成损害,认真进行爆破设计、做好安全防护措施、制定应急预案、加强爆破监测等,通过实践证明,施工方法可行。以本工程的成功经验,对以后类似施工有一定借鉴意义。
Taking the construction shaft of Shayuan Station - Fenghuang Xincun Station in Guangzhou Metro Line No. 2 and No. 8 as an example, this paper summarizes the construction of shaft drilling and blasting methods for urban subway construction. Considering the impact of blasting vibration on the adjacent buildings and the prevention of damage caused by blasting flying stones on the pedestrians and vehicles in the past, the Blasting Design was conscientiously carried out, the safety measures were taken, the contingency plan was formulated and the blasting monitoring was strengthened. The practice proved that the construction method was feasible. With the successful experience of this project, it is of some reference to similar construction in the future.
