摘要： PROBLEM TO BE SOLVED: To provide a prestress introduction method for a lining body with excellent construction efficiency and high safety without requiring a large-scale apparatus and a segment for the lining body. SOLUTION: A prestress is introduced into each segment 1 beforehand by fixing both ends of a PC steel material into which a tension force P1 is introduced to the joint plate of a joint between segments. When the segments 1 are assembled in a ring-shape in a construction site for a shield tunnel, a tightening force P2 according to the prestress introduced into the segments 1 is introduced between the joint plates 2 of the adjacent segments 1 and the joint plates 2 are tightened to each other so as to introduce a generally uniform prestress into the entire part of the segment ring.

摘要： PROBLEM TO BE SOLVED: To provide an anchoring method for a shear reinforcement material capable of using a grout material having fluidity as in a downward execution of construction, and excellent in economic efficiency and construction efficiency. SOLUTION: An insertion hole 3 is drilled upward in a concrete structure 1. The shear reinforcement material 4 is arranged on a lid body 5 tightly closing the insertion hole 3. A degassing hose 6 is inserted in a through-hole formed in the lid body 5, and a front end thereof is positioned at a front end of the insertion hole 3. A sheath tube 9 is interposed to prevent the grout material from leaking from an outer peripheral part of the degassing hose 6. After completion of setting up of the device, injection of the grout material 8 is started, and the air in the insertion hole 3 is discharged through the degassing hose 6. When the insertion hole 3 is filled with the grout material 8, the degassing hose 6 is pulled to the lid body 5, and is plugged. After that, pressurization from a grout material injection port 7 is stopped, and the grout material injection port 7 is closed. After hardening and curing of the grout material 8, the lid body 5 is removed and the surface of the concrete is finished. COPYRIGHT: (C)2010,JPO&INPIT
