PARTITIONING FACILITY CONSTRUCTION STRUCTURE AND METHOD IN APPROACH PART OF UNDERPASS TUNNEL

摘要

PPROBLEM TO BE SOLVED: To achieve high efficiency of construction work by realizing a simple construction structure and shorten work hours. PSOLUTION: This partitioning facility construction structure 1 constructed in the approach part 2A of the underpass tunnel constructed by a shield tunneling method is provided with a first joint 21 buried into an upper end face 20a of a segment 20 in advance when manufacturing the segment 20 and a second joint 11 provided on a lower end face 10a of partitioning facility 10. The first joint 21 is engaged with the second joint 11 to attach the partitioning facility 10 to a part above the approach part 2A. PCOPYRIGHT: (C)2008,JPO&INPIT
