A high-pressure indoor work method including a connection step for connecting to the stay-type man lock 3 is disclosed (claim 1, claims [0044] to [0064] of the specification, in the drawing. See FIGS. 1 to 4 and the like).

However, the high-pressure indoor work method described in Patent Document 1 is a normal elevating facility, not a facility specialized in rescuing a worker who has become ill in a high-pressure work room, and is a work in which the physical condition has deteriorated. It was necessary for a member (rescuer) to carry the rescuer's body into the chamber (portable man lock 2) of the lifting facility by himself or another colleague.

Further, the rescue facility used in the pneumatic caisson method is disclosed in Patent Documents 2 and 3. For example, in Patent Document 2, a capsule outer cylinder (1) having a substantially cylindrical shape and provided with a door (4) that can be opened and closed, and a lid (2) provided on the upper portion of the capsule outer cylinder (1). And an expanded metal (3) provided at the lower part of the capsule outer cylinder (1) and provided with a chair (8) on which the worker (a) sits, and connected to a hanging lifting device. , A worker rescue capsule for a utility caisson capable of accommodating a worker (a) in a work room (12) of a utility caisson (10) through a shaft (14) is disclosed (Patent Document 1). 1. The scope of the utility model registration request, paragraphs [0008] to [0015] of the specification, FIGS. 1 to 5 of the drawing, etc.).

However, the worker rescue capsule for pneumatic caisson and the rescue method described in Patent Document 2 are the same as the capsule described in Patent Document 1, in which another worker holds a person requiring rescue and the rescue capsule (chamber of an elevating facility). The problem of having to carry it in) was not solved.

Further, Patent Document 3 describes a material shaft 6 extending upward with respect to the work chamber 3, a material lock 10 provided at a position above the work chamber 3 of the material shaft 6, and a worker M1 in the work chamber 3. The material is provided with a storage device 20 for raising and lowering between the work room 3 and the material lock 10 through the inside of the material shaft 6, and a lifting machine 30 for raising and lowering the storage device 20 from above the material lock 10. The lock 10 discloses a rescue facility having a treatment space 10a for treating the worker M1 (claim 1, claims of patent document 3, paragraphs [0020] to [0043] of the specification, drawings. 1 to 4 etc.).

The rescue equipment described in Patent Document 3 has some improvements to the above-mentioned problems in that the chair is provided with a deformable stretcher 25. However, in the rescue equipment described in Patent Document 3, it is necessary for another worker to carry the person requiring rescue into the accommodation device 20 on a stretcher 25. In a work room where the ground is extremely uneven during excavation due to high pressure, it is very hard work for other workers to carry a rescuer who cannot move at all by himself, and the health condition of the other workers to be rescued is also a concern. There was also a problem.
