摘要
结合昆明地铁5号线圆通公园竖井岩层开挖施工,阐述了在市区内竖井岩层开挖不允许进行爆破施工的前提下,先进行铣槽施工制造临空面,再进行二氧化碳静态爆破的施工技术。为今后类似工程施工提供借鉴。
Combined with the excavation of the shaft rock formation of Yuantong Park in Kunming Metro Line 5, this paper expounds the construction technology that under the premise that the excavation of shaft in urban area is not allowed to carry out blasting construction, the milling slot construction is firstly carried out to produce free face, and then the static blasting of carbon dioxide is carried out. It provides reference for similar projects.
