摘要： PROBLEM TO BE SOLVED: To provide a tunnel reinforcing material separation detecting method and a device for accurately measuring separation of a reinforcing material in a reinforcing place in a tunnel at a remote point.
SOLUTION: When reinforcing an inner wall surface of a tunnel lining 3 by a reinforcing material 31, after confirming a position of a crack 4, an optical fiber 2 is arranged in the direction orthogonal to the crack 4 on a surface of the reinforcing material 31 after finishing reinforcement, and two points are adhered and fixed by a fixing member 5. A strain measuring instrument 6 for measuring strain of the optical fiber 2 in a separation monitoring position and an arithmetic processing unit 7 are connected to a starting end part of the optical fiber 2. The strain measuring instrument 6 inputs the strain to the arithmetic processing unit 7 by measuring the strain of the optical fiber 2 in the separation monitoring position. The arithmetic processing unit 7 stores the strain measured by the strain measuring instrument 6, and compares strain measured last time with strain measured this time always or with every specific time, and detects separation of the reinforcing material 31 by detecting a state of changing to compression strain from tensile strain.

摘要： PROBLEM TO BE SOLVED: To accurately measure the width of crack in the inner wall of a tunnel. SOLUTION: An optical fiber 2 is laid on an inner wall along the longitudinal direction of a tunnel. At this time, the optical fiber 2 is fixed on the wall surface with a bonding agent so as to straddle cracks 4, without slack in the fiber. The starting end part of the optical fiber 2 is connected to a strain meter 6 and an arithmetic processing unit 7. This arithmetic processing unit 7 is made to store a relationship between the strain of the optical fiber and crack width measured beforehand in a strain/width table. The arithmetic processing unit 7 calculates the quantity of strain change from the initial strain at the installation of the optical fiber based on the difference between the present strain measurement value and the initial strain. Subsequently, the quantity of strain change is substituted into the relationship between the strain of the optical fiber and the crack width, which has been stored in the strain/width table, to calculate a present crack width 4.

摘要： PROBLEM TO BE SOLVED: To develop a water absorbing performance of a water absorbing polymer proper by a method wherein prior to mixing with a setting material, a water absorbing polymer is firstly mixed with water or accelerator-mixed water and thereafter, a setting material is charged and mixed by kneading. SOLUTION: Prior to mixing with a setting material, a water-absorbing polymer is mixed with water or an accelerator-mixed aqueous solution. The water-absorbing polymer is sufficiently expanded. Thereafter, the setting material is charged into water and mixed by kneading. Then, the manufactured setting filler reacts by water absorption in water in a state wherein the water absorbing polymer is low in alkali concentration. Herein, cement or the like as the setting material, that having aluminate or the like as a main material, and polyacrylate crosslinked material or the like as the water absorbing polymer are used. Thereby, a water absorbing performance possessed by the water- absorbing polymer itself can be sufficiently developed, a use amount of an especially high costed water-absorbing polymer can be reduced, and the cost can be extremely decreased.

摘要： PURPOSE: To carry out a repairing work without stopping the overall running of a train in particular, in a repairing work method of an existing tunnel such as the widening of the tunnel and the repairing of the peripheral wall. CONSTITUTION: A reinforcement of a natural ground 5 by rock bolts; an excavation and exhaust of a repairing area; an erection of a mine timbering 1 to an excavated area; a partitioning which consists of an end plate with an air fence 7 to the clearance between the mine timbering 1 and a natural ground; and the installing of a face protective work 10 to the excavated face; are carried out. Furthermore, a series of works including the installing of a collapse protector to an existing arch in a nonexcavated part; the assembling of a PC plate 2a between the mine timberings; and the pouring and the filling of a backfilling mortar layer 3 to the clearance between the PC plate and the natural ground; are repeated as one cycle, so as to repair the full length of the tunnel.
