２５のコンクリート工事を行なう。The construction of this concrete secondary containment vessel has conventionally been carried out by the following method. That is, in the embodiment shown in FIG. After that, the containment vessel cylindrical inner lining 18 is assembled on the containment vessel bottom 17,
Furthermore, the conical one-stage lining 20 is assembled. In accordance with the assembly of these linings, concrete work for the containment vessel concrete frame portions 19 and 21 is performed on the outside thereof. In parallel with these works, the pressure vessel pedestal 22 is assembled, and then a diaphragm floor 23 is installed between the pedestal 22 and the conical first-stage lining 200.
Equipped with and fixed. Furthermore, the lining 24 of the two-stage conical part is assembled, and the pipe whip structures 27 and 28 are temporarily installed in the dry well 26, and then the concrete work of the atomic deshielding walls 29, 30 and the concrete frame 25 of the two-stage conical part is started. Do the following.

なう。After that, in order to install the containment vessel ceiling lining 31 and the concrete frame 32, temporary shoring was erected from the pipe whip structures 27 and 28, and the containment vessel was similarly installed from the upper end of the reactor shroud wall 30. After assembling temporary shoring to support the top, ceiling lining 31
Construction will be carried out. After the lining welding and inspection are completed, construction of the concrete frame 32 begins and concrete is poured.

8 and assemble temporary shoring, and then construct the containment vessel ceiling lining 31, which delays the start of concrete work on the containment vessel ceiling and prolongs the construction period of the containment vessel. In addition, the support for the top of the containment vessel cannot be erected until the reactor wall 29.30 is completed, so the completion of the reactor wall is a critical path for the construction of the containment vessel ceiling. However, since a large number of temporary supports must be erected within the dry well, the number of man-hours will also increase significantly. Furthermore, work inside the dry well could not begin in earnest until after the shoring was dismantled and transported, making the completion of work inside the containment vessel extremely slow, and the temporary equipment assembly and dismantling cost 9%2. This reduces the decrease in work efficiency and the significant decrease in safety by half.
これらの結果、全体の建設工期が著しく長期に及び、安
全性も低下するという不都合があった。As a result, there were disadvantages in that the overall construction period was extremely long and safety was also reduced.

解決する事にあった。The purpose of the present invention is to shorten the process and improve safety, which are the most difficult problems to improve among the many problems encountered in nuclear power plants. First, because there is not enough electricity distributed to the installation location and structure of the temporary shoring for constructing the containment vessel ceiling lining, the overall The purpose of this project was to solve the problem of delays in the construction period, as well as the problem of reduced work efficiency and safety caused by delays in the construction period.

きた。Means for Solving Problem C] The above purpose is to pass a beam through the reinforced concrete frame that forms the upper structure of the reactor containment vessel, connect this beam to the containment vessel ceiling lining, and connect it to the containment vessel ceiling lining. By lifting and holding it, concrete can be easily placed. In addition, the shoring does not have to be removed after a curing period after it is placed, and the beams that serve as the shoring are embedded inside the conocrete that has been placed, which greatly shortens the construction process. Additionally, by shortening the process, we were able to improve workability and safety.
