font-size: 14px; text-indent: 2em; visibility: visible;"><span style="font-size: 16px; color: rgb(0, 0, 0); visibility: visible;">城开高速是我市首条连接陕西省的高速公路通道，因地处秦巴山区，建设难度非常大。记者在采访中了解到，作为城开高速公路建设的控制性工程之一，鸡鸣隧道建设推进有序。</span></p><p style="color: rgb(63, 63, 63); font-size: 14px; text-indent: 2em; visibility: visible;"><span style="font-size: 16px; color: rgb(0, 0, 0); visibility: visible;">鸡鸣隧道单幅全长 7435.2 米，穿越三个乡镇，地处巴山峡谷北面，集中了国内高速公路建设当中所有不良地质，如高地应力、大变形、暗河、岩溶、高瓦斯、突泥突水等多重风险，隧道最大埋深1148米。</span></p><p style="color: rgb(63, 63, 63);

font-size: 14px; text-indent: 2em; visibility: visible;"><span style="font-size: 16px; color: rgb(0, 0, 0); visibility: visible;">据城开高速B1标段鸡鸣隧道技术员孙海申介绍，鸡鸣隧道自进洞以来共遭遇了十一次<span style="color: rgb(0, 0, 0); font-size: 16px; letter-spacing: 1.5px; text-indent: 28px; visibility: visible;">突泥突水</span>，该隧道计划是穿越9层煤层，现在已经顺利地穿越了7次煤层，将在确保安全的前提下，加班加点确保隧道尽早贯通。</span></p><p style="color: rgb(63, 63, 63); font-size: 14px; text-indent: 2em; visibility: visible;"><span style="font-size: 16px; color: rgb(0, 0, 0); visibility: visible;">2021年3月，鸡鸣隧道出口右洞在实施超前钻探中突遇煤层，瓦斯浓度已超过10%。经过近半年的技术整改，同时还引进了防暴设备，目前施工进展顺利。</span></p><p style="color: rgb(63, 63, 63);

font-size: 14px; text-indent: 2em; visibility: visible;"><span style="font-size: 16px; color: rgb(0, 0, 0); visibility: visible;">“在施工过程中遇到了高瓦斯，我们将原有的传统设备改造成瓦斯防爆设备，在这个基础上还增加了瓦斯传感器，以便实时掌握洞内的空气质量情况，一旦瓦斯浓度超标，就立即停工撤人，保证施工人员的生命安全。”孙海申说。</span></p><p style="color: rgb(63, 63, 63); font-size: 14px; text-indent: 2em; visibility: visible;"><span style="font-size: 16px; color: rgb(0, 0, 0); visibility: visible;">此外，该工程在建设过程中，还使用了隧道人员定位及综合气体监测管理系统。该系统的使用，实现了车辆进出自动管理，隧道危险气体实时监测，24小时视频监控隧道人员进出与定位管理，切实提高了施工效率，保障了施工安全。</span></p><p style="color: rgb(63, 63, 63);
