Tunnel junction structure, tunnel provided with the construction methods and tunnel junction structure of the tunnel junction structure

摘要

PROBLEM TO BE SOLVED: To provide a tunnel joint structure capable of preventing water leakage from a joint part, a construction method of the tunnel joint structure, and a tunnel including the tunnel joint structure.SOLUTION: For the tunnel joint structure, a tunnel 1 is constructed by joining a plurality of elements 6L, 6R... having a longitudinal direction in a tunnel longitudinal direction, in a tunnel circumferential direction, and a joint part 7 having a prescribed space is formed between the adjacent elements 6L and 6R. The tunnel joint structure includes a partition member 8 for partitioning the inside of the joint part 7 formed between the elements 6L and 6R adjacent on the left and right into an upper space and a lower space, and high-fluidity concrete is placed in the lower space inside the joint part 7.
