摘要
在地铁车站施工过程中,经常遇见石方,由于传统爆破方法危险性大,国家对于炸药的管控也是相当严格,时常无法批到炸药,无法对石方进行爆破,尤其针对地铁周边环境较复杂不宜采用爆破施工且基坑开挖施工需要连续作业,尽量缩短基坑裸露时间,确保基坑安全,本文通过在周边环境复杂的地铁基坑石方开挖实例分析,通过采用液压劈裂技术进行石方开挖方案可行并取得了较好的效果。
subway station construction,rock is often encountered,because of the danger of traditional blasting methods,the state is also very strict on explosives control,often unable to approve explosives,rock blasting,especially in the surrounding environment of the subway is not suitable for blasting construction and excavation of foundation excavation construction needs continuous operation,as well as to reduce the foundation excavation exposure time,ensure the safety of the foundation excavation,this paper through the complex underground excavation of a good example,and through the application of hydraulic splitting technology feasible excavation method.
