城市地铁风井金属膨胀剂开挖和爆破开挖技术对比
|
摘要
结合青岛地铁2号线一期工程延安路站1号风井开挖工程,为了减小振动对城市地铁周边建筑物及市政建设管道等的影响,对金属膨胀剂破岩开挖、爆破开挖进行振动数据分析。现场实践结果表明,金属膨胀剂破岩施工较爆破施工容易控制振速,但金属膨胀剂破岩施工的材料成本约为爆破施工的3.4倍,在以后的施工中可以根据不同的环境和施工要求选择适宜的施工方法。
In this paper,comparison and contrast is made between the vibration caused by metal expansive agent blasting and that caused by explosive blasting,so as to minimize the influence of the excavation of No. 1 ventilation shaft of Yan'an Road Station of Phase 1 of No. 2 Line of Qingdao Metro on the surrounding buildings and municipal utility lines. The practice shows that,compared to the vibration caused by explosive blasting,the vibration caused by metal expansive agent blasting is easier to be controlled,but the cost of the metal expansive agent blasting is 3. 4 times that of the explosive blasting. It is proposed that appropriate blasting methods should be adopted on basis of the specific environment conditions and construction requirements.
