Abstract
Efficiency of installation work of equipment such as an ECCS pump is enhanced. In an installation method of equipment, a pit can unit in which an upper side frame, a pit can, various reinforcing steels including vertical reinforcing bars reinforcing the above from a periphery, and an anchor plate supporting mechanism are integrated is manufactured in advance, and the pit can unit is placed on an MMR via a lower side frame. Further, an anchor bolt unit is disposed on the anchor plate supporting mechanism after primary concrete is deposited, a relative positional relationship of respective foundation bolts relative to the pit can is corrected by using a template, and secondary concrete is deposited under the state in which the positional relationship is corrected. After that, the ECCS pump is carried into the pit can, and an installation of the ECCS pump is completed by fixing the carried ECCS pump through the respective foundation bolts of which bottom sides are embedded.
