摘要： PROBLEM TO BE SOLVED: To provide a man lock device which can be mounted to a small-to-medium-diameter shield machine without extending the machine length of the shield machine. SOLUTION: The man lock device is provided with a partition mounting segment 34, a pressure partition 36, and a man lock 37 mounted to the pressure partition 36. The partition mounting segment 34 can be assembled along the inner periphery of the shield frame 3 of the shield machine 1, and it can also be knocked down. The pressure partition 36 is attached to the partition mounting segment in a detachable manner, and partitions the interior of the shield frame 3 into the front and the rear. The man lock 37 has an atmospheric pressure adjustment chamber 43, a first door 45, and a second door 47. The atmospheric pressure in the atmospheric pressure adjustment chamber 43 can be adjusted, and the first door opens and closes the opening 44 which connects the atmospheric pressure adjustment chamber 43 and a space located at the rear of the pressure partition 36. The second door opens and closes the opening 46 which connects the atmospheric pressure adjustment chamber and the space located at the front of the pressure partition. COPYRIGHT: (C)2011,JPO&INPIT
