SEGMENT FOR NON-OPEN-CUT METHOD, SHIELD TUNNEL, AND NON-OPEN-CUT METHOD

摘要

PROBLEM TO BE SOLVED: To provide a segment for a non-open-cut method which can greatly reduce time and labor required for installation work of a rail for carrying a carry-in pipe (rail facility).

SOLUTION: A segment is used for a non-open-cut method where a plurality of carry-in pipes 5 are carried into a shield tunnel whose inner wall is composed of a plurality of segments 9-11 using a carriage 32 and a pipe line is laid in the shield tunnel by connecting the carry-in pipes 5 to each other. Rails 20 for traveling the carriage 32 are provided integrally with the inside of an arc-shaped segment body of the bottom segments 9 disposed on the bottom inside the shield tunnel, and the rails 20 have a plate-like shape long in a lengthwise direction of the shield tunnel.
