【摘要】：瓦斯燃烧和爆炸是铁路、公路隧道施工中的严重灾害之一,在我国铁路、公路隧道建设史上都发生过相应事故,造成很大损失。近年来,在我国西南山区的铁路隧道建设中,多次遇到非煤系地层瓦斯隧道。研究非煤系瓦斯隧道的施工技术和组织管理方案,对高速铁路的安全施工、安全运营,都具有重要的工程实践意义。论文结合成渝铁路客运专线龙泉山隧道工程,根据勘察设计期间的地质勘探资料,分析了龙泉山隧道天然气瓦斯施工风险。在瓦斯预报监控、钻爆开挖技术、施工通风技术、电气设备与作业机械等施工技术方面开展研究。在隧道施工过程中,组织开展瓦斯超前地质预报以及瓦斯监控,提出了铁路客运专线长大瓦斯隧道的钻爆开挖施工工法；在隧道通风方面,对低瓦斯工区采用压入式通风,对高瓦斯工区采用压入式和巷道式相结合的通风方式：并进行了阶段的通风布置及通风设备的优化比选。同时,从隧道通风管理、人员管理、应急救援等方面开展了施工管理研究,制定了成渝铁路客运专线龙泉山隧道施工管理措施,设置了通风管理机构,制定了通风管理制度,编制了隧道瓦斯突出事故应急救援处置预案等。通过以上研究分析,找到针对非煤系瓦斯隧道的施工技术与施工管理方案,确保了龙泉山隧道工程的顺利完成,对同类型隧道施工具有借鉴意义。
[Abstract]:Gas burning and explosion is one of the serious disasters in the construction of railway and highway tunnel. In the history of railway and highway tunnel construction in China, the corresponding accidents have occurred, resulting in great losses in recent years. In the construction of railway tunnel in southwest mountainous area of our country, the non-coal measure gas tunnel is encountered many times. The construction technology and organization and management scheme of non-coal measure gas tunnel are studied, and the safe construction and safe operation of high-speed railway are studied. Combined with Longquanshan tunnel project of Chengdu-Chongqing railway passenger dedicated line, according to the geological exploration data during the period of survey and design. The risk of natural gas construction in Longquanshan Tunnel is analyzed. The research is carried out in the aspects of gas forecast monitoring, drilling and blasting excavation technology, construction ventilation technology, electrical equipment and working machinery, etc. To organize the advance geological forecast of gas and gas monitoring and control, the construction method of drilling and blasting excavation of long and long gas tunnel in railway passenger dedicated line is put forward. In the aspect of tunnel ventilation, pressurized ventilation is adopted in low gas working area. The ventilation mode of high gas working area is combined with pressure type and roadway type. The ventilation layout and ventilation equipment are optimized and compared in the stage. At the same time, from the tunnel ventilation management, personnel management. Emergency rescue and other aspects of construction management research, formulated Chengdu-Chongqing railway passenger dedicated Longquanshan tunnel construction management measures, set up ventilation management agencies, formulated ventilation management system. Through the above research and analysis, we find the construction technology and construction management plan for non-coal measure gas tunnel, which ensures the smooth completion of Longquanshan tunnel project. It can be used for reference in the construction of the same type of tunnel.
