CONSTRUCTION MANAGING APPARATUS AND CONSTRUCTION MANAGING PROGRAM FOR SHIELD TUNNEL

PROBLEM TO BE SOLVED: To solve a problem that a segment wall structure is chipped or cracked by the impact of the inner peripheral surface of a shield machine at the rear end of the body tube with the outer peripheral surface of the segment wall structure at the front end when the tail clearance is small when the shield machine is actually advanced with a tail clearance set small. SOLUTION: This construction managing apparatus comprises a shield machine present output processing means 32 for displaying the present state of the shield machine on an output device 23 by inputting the present information on the shield machine, a segment present output processing means 33 for displaying the present state of the segment wall structure on the output device by inputting the present information on the segment wall structure formed of segments, and a tail clearance output processing means 36 for displaying, on the output, the minimum value of the shortest distances between the inner peripheral surface of the present shield machine at the rear of the body tube and the end edge of the outer peripheral surface of the segment wall structure at the distal end, and displaying, on the output device, the minimum value of the shortest distances between the rear end edge of the inner peripheral surface of the body tube and the outer peripheral surface of the segment wall structure at the distal end.
