摘要： PROBLEM TO BE SOLVED: To provide a segment, and a soil improving method and a soil improving device using the segment capable of changing the direction of a chemical injection pipe in the circumferential direction of a tunnel, along the segment while ensuring the strength of the segment as strength for use as a tunnel wall. SOLUTION: The segment 1 is divided in three segment pieces in the axial direction of the tunnel, and the center segment piece 1a is provided with a swing member 4 having a hole 3 for inserting a chemical injection pipe 2, swingingly at least in the circumferential direction of the tunnel. A recessed part 6 for allowing the swing of the pipe 2 inserted through the hole 3 of the swing member 4 is formed in the outer peripheral surface of the front and center segment pieces 1a, 1b, and a space 8 for allowing the swing of the pipe 2 inserted through the hole 3 of the swing member 4 is formed in the inner peripheral surface of the rear and center segment pieces 1a, 1c. These front, center and rear segment pieces 1a, 1b, 1c are connected to form the segment 1. COPYRIGHT: (C)2006,JPO&NCIPI
