Description of the Related Art The present applicant has developed and disclosed a technique for manufacturing a concrete arc-shaped plate-shaped segment used in a shield method or a propulsion method by centrifugal molding. For example, there is Japanese Patent Application No. 5-303930.
This technology divides the circumference of a tunnel liner into several parts,
Using individual molds for manufacturing each divided arcuate plate-shaped liner, concrete is filled in the individual molds in advance and compacted by vibration, and then the individual molds of this arcuate plate-shaped liner are centrifugally formed. Install several inside the drum, 20-30
The concrete is manufactured by applying a centrifugal force of G (G is the acceleration of gravity) to densify the concrete and curing the concrete.

The present invention is directed to a centrifugally formed tunnel liner in the form of an arc-shaped plate, which is in close contact with the bottom plate and one of the arc-shaped side plates of the tunnel. A centrifugal molding tunnel liner characterized by disposing a joint member covering the entire arcuate end surface of the liner in a mold, casting concrete in the mold, and integrating the joint member and concrete. Is a method of forming a joint. This joint member is often a metal joint,
It may be RP or others. In addition, it is preferable that a sealing material is interposed between the joint surface of the joint member and the concrete, and it is preferable that the joint surface on which the sealing material is interposed be the outer peripheral surface of the tunnel liner because the sealing property is high. Also before
The joint member has an F-shaped cross section as shown in FIG.
Then, the top surface of the F-shape is brought into close contact with the arc-shaped side plate,
The surface is placed in the mold so that the surface is in close contact with the bottom plate of the mold .

い。According to the method of forming a joint of a centrifugally formed tunnel liner of the present invention, a joint member is inserted into a centrifugally formed formwork, concrete is cast, and integrated by centrifugal forming. Therefore, they are firmly connected and no leakage or the like occurs. The material and shape of the joint member are not limited, and the joint member has a shape that is in close contact with the inner surface of the mold. Metals such as steel joints are suitable as joints because welding work and the like are easy. It does not exclude FRP and others. Rubber, plastics, metal, or the like can be used as the sealant. It is preferable that the joint surface between the joint member and the concrete be the outer peripheral surface of the tunnel liner because it can be compacted at the time of compaction by centrifugal force and can obtain extremely high sealing properties.
