るライナの構築方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of constructing a liner for a reinforced concrete containment vessel wall, and in particular, the liner is constructed 4-4 with reinforcing bars placed around the liner in advance to improve rigidity and shorten the construction period. The present invention relates to a method of constructing a liner that can achieve the following.

ている。Conventionally, in order to construct a platform for constructing liners, the reinforcing concrete wall part and the liner part were constructed separately at the same site at the construction site. The structure is connected in a ring shape, and a cut tee is provided along the vertical direction on the outer circumferential surface. On the other hand, for the reinforced concrete wall section, after the reinforcing process for the liner was completed, reinforcement was placed around the liner, and then the space was filled with liner d5 and formwork for concrete pouring. I try to construct it in one step by making it and pouring concrete.
したがってライナの補強作業が終了しないど」ンクリ！
ト打設工程に移行できず、長い工期が必要である。Therefore, the reinforcing work on the liner has not been completed yet!
It is not possible to move on to the pouring process, and a long construction period is required.

ある。The present invention has been made based on these backgrounds, and its purpose is to place at least a portion of the reinforcing bars around the periphery of the liner, and to perform concrete pouring work while stacking the reinforcing bars. This aims to increase the rigidity of the thin liner, simplify the reinforcing work prior to concrete pouring work, and shorten the overall construction period.
