摘要： PROBLEM TO BE SOLVED: To provide a splicing device for waterproof sheets by which waterproof sheets can be spliced to each other by means of a self-propelled splicing device even when a shielding excavator is driven. SOLUTION: The splicing device is used for connecting the overlapped part of a new waterproof sheet laid between an underground tunnel excavated by a shielding excavator and segments and an existing waterproof sheet and constituted of a self-propelled welding device joining the overlapped part and a support device supporting the welding device so as not to drop when the upper part of the waterproof sheets is spliced by the welding device. In this case, the support device of the splicing machine is constituted of a welding device guide 4 supporting and guiding the welding device when the upper part of the overlapped part of the waterproof sheets is spliced, a fitting means composed of metal fittings 4a or the like attaching the welding device guide 4 to the rod 3a of a shield jack so as to be axially unmovable and relatively rotatable, and right and left metal blocks 4b preventing the welding device guide 4 from having a tilt.

摘要： PROBLEM TO BE SOLVED: To improve the execution by installing a waterproof sheet in an overlapping manner on an existing waterproof sheet in a space provided on a cutting face side of an existing segment, and performing automatic welding. SOLUTION: A waterproof sheet installation device comprises a long stroke jack 1, a rod 2, an arm 3, a mobile welding machine 4, and a welding machine guide 5. During the face cutting, a turning ring 10 mounted on a ring girder 14 is turned to turn the arm 3, and a new waterproof sheet 8 held by the arm 3 is installed in an overlapping manner on the existing waterproof sheet 7 along the inner circumferential surface of a tail plate 9. Then, following the operation, the overlapped part of the sheets 7, 8 is hold by the welding machine 4, and the sheets 7, 8 are welded in a mobile condition. When the welding machine 4 is moved to an upper hemisphere part, the welding machine 4 and the sheets 7, 8 are prevented from being sagged by the welding machine guide 5 provided on a dead stroke part of the rod 2. Safe execution can be achieved parallel to the excavation, and the welding can be achieved with excellent accuracy.
