摘要： PROBLEM TO BE SOLVED: To provide a tunnel timbering material having excellent construction ability of spreading construction of the tunnel timbering material and to provide a tunnel excavation method using the timbering material, in a excavation of a tunnel by a tunnel boring machine (TBM machine). SOLUTION: At least one spot of a joint between pieces P and P, of which a timbering material is composed, forms hinge structure H. The inner peripheral ends of end faces T and T, positioned opposite to each other, of adjoining two pieces P and P of which the hinge structure H is composed are served as a hinge fulcrum, and during spreading, the end faces are formed in an adhering shape. A soil drop prevention plate 24 is arranged at the outside of the end part, and after spreading, the two end faces are fastened against each other by a fastening member. A gripper to support the reaction force of an excavator is arranged in a state to make contact with the inner peripheral surface of the timbering material. The excavator is supported by a gripper and thrust by a thrust jack and simultaneously with excavation, erection of the timbering material is effected. Further, the excavator is supported by a front jack and the gripper is pulled to the excavator side. Simultaneously with support of the excavator by the gripper, the timbering material is spread and excavation is effected.

摘要： PURPOSE:To prevent the peeling between skin plates and concrete by water pressure and prevent a water leak from joint section mortar. CONSTITUTION:A concrete filling space 4 is formed with a steel frame 1 and skin plates 2, 3 of a steel plate, and concrete 5 is filled in this concrete filling space at the injection pressure higher than the expected water pressure to form a synthetic segment A introduced with prestress into the skin plates 2, 3. Coupling sections 10, 11, 12, 13 of the steel frames 1 of the synthetic segments A are coupled to form a mortar filling space 20 between the steel frames 1, and mortar 21 is filled into this mortar filling space 20 at the filling pressure higher than the expected water pressure.
