摘要： PURPOSE: To improve execution efficiency by providing an assembling frame provided with a traverse roller, a rail, and a support roller outside a tunnel, assembling lining plates for multiple spans, then carrying them into the tunnel. CONSTITUTION: An assembling frame 10 constituted of a fixed support stand 12 fixed on a base 11 and a moving support stand 12' having a moving mechanism 13 is installed outside a tunnel. Circular arc-shaped tunnel lining plates 4 for multiple spans are connected on the assembling frame 10 to form a large block, and a block formed on the moving support stand 12' is connected to the block of the lining plates 4 formed on the fixed support stand 12 to form an arch-like large block. The arch block 4 is shifted onto a conveyance/ installation machine by a crane or the like, and it is carried into the tunnel and fitted. The next lining plates 4 are assembled on the assembling frame 10 during this fitting work so that they can be continuously conveyed in sequence with no time lag. Execution efficiency can be improved.

摘要： PURPOSE:To promote water pressure resistance by laminating unvulcanized swelling rubber and unvulcanized unswelling rubber thicker than the swelling rubber to specify the volume ratio, and vulcanizing them at a time to from a longer sealant. CONSTITUTION:High water absorbing resin having an average particle size of 10-20mu is combined in blend system rubber such as chloroprene rubber, etc., and unvulcanized swelling rubber 1a having 1.8-2.3 times of volume expansion against purified water is formed. Unvulcanized unswelling rubber 1b having 5-15kg/cm of Young's modulus and consisting of isoprene - isobutylene copolymerization rubber is formed. The swelling rubber 1a and unswelling rubber 1b are so laminated that the volume ratio of them becomes 20/80, and they are vulcanized at a time of form a longer sealant. In addition, the sealant 1 is stuck on a recessed groove 2a in a joint face of connection units so that the unswelling rubber 1a is turned downward.

摘要： PROBLEM TO BE SOLVED: To realize the opening and closing of each bulkhead board, which forms the peripheral joint face of a segment in a form for placing precast concrete for forming the segments formed by peripherally and axially splitting a tunnel lining, and, improve the safety at the opening and closing operation of the bulkhead board. SOLUTION: Two main brackets 31 and 31 are hangingly provided on the under surface of each one of bulkhead boards 30 provided at the right and the left of a base 12 and, in addition, bridgedly connected with a horizontal shaft pivotally attached to the base 12. Further, a crank 36 is arranged below the bulkhead board 30. When the crank 36 is pivoted, the bulkhead board 30 is also pivoted through a connecting rod 46. Furthermore, a compression spring 58 arranged below the bulkhead board 30 energizes the bulkhead board 30 towards the setting direction at all times. In addition, the opening and closing mechanism of the bulkhead board 30 is so constituted as to be brought under clamped state when the crank 36 passes over its lower dead point.
