介绍了盾构气压过渡舱的用途,对其结构型式进行了详细分析,论述了进舱出舱应注意的问题、气压过渡舱最高工作压力、以及加减压呼吸气体,提出了在气压过渡舱内应配置的安全保障系统。结合国内目前盾构的引进与盾构气压过渡舱的研发情况,对存在的问题进行了分析,提出了相应的措施。 This paper introduces the use of shield atmospheric pressure transition cabin and analyzes its structure type in detail. The problems that should be noticed when entering the cabin, the maximum working pressure of the air pressure transition cabin, and the pressure of breathing gas are introduced. Within the security system should be configured. Combined with the introduction of the current domestic shield and the research and development of the shield atmospheric pressure transition cabin, the existing problems were analyzed and the corresponding measures were put forward.
