摘要
结合成都地铁1号线三期低瓦斯盾构隧道的实际情况,提出了低瓦斯工况下盾构电气防爆改装、盾构区间瓦斯监测及通风方案,并探讨了盾构穿越地质断层带瓦斯抽放措施,保障了地铁1号线三期低瓦斯盾构法隧道的顺利完工。
Combining with the fact of the low-gas shield tunnel in the Third Phase of No. 1 Line of Chengdu Subway, the paper points out the re-construction of the electric explosion-proof in low gas, gas monitoring and ventilation scheme between shields, and ventilation scheme, and ex-plores the methane drawing of the in the shield through the geological faults, so as to ensure the construction of the shield method of the Third Phase of the No. 1 Subway.
