盾构机械化施工方法在城市隧道工程中得到了普遍运用。盾构掘进过程中可能会因遇到障碍物或刀具磨损等情况而不得不带压开舱、实施维修等相关作业。带压开舱作业涉及到安全和职业健康等诸多方面,具有技术难度和挑战性。为此住房和城乡建设部制定、颁布了《CJJ 217-2014盾构法开舱及气压作业技术规范》,并于2014年12月1日起实施。为方便国内读者了解国外相关规范要求,编辑部组织翻译了国际隧道协会第五工作组编写的《隧道高压压气作业实践指南》,以供读者参考借鉴。
Shield mechanized construction methods in urban tunnel project has been widely used. In the process of shield tunneling, it may be forced to open the cabin due to obstacles or tool wear, carry out maintenance and other related operations. With open-pressure tanker operations related to safety and occupational health and many other aspects, with technical difficulties and challenges. For this purpose, the Ministry of Housing and Urban-Rural Development formulated and promulgated the “Technical Specifications for CJJ 217-2014 Shield Method Opening and Pneumatic Operation” and implemented it on December 1, 2014. In order to facilitate domestic readers to understand the relevant requirements of foreign countries, the editorial department has organized and translated the Guidebook of Tunneling Compressed Gas Operation Practiced by International Tunneling Association Working Group V for readers’ reference.
