Abstract

PURPOSE:To shorten a construction period substantially by placing a concrete man-made-rock (MMR) around a circulating-water piping as a permanent structure, in advance. CONSTITUTION:A levelling concrete 2 and H-beams are place concurrently on a rock formation 1 after completion of an excavation work and then an MMR 6 is placed prior to following works. A tunnel shaped CWP construction space 10 of which surrounding is reinforced by reinforcing bars 5, is formed in the MMR 6, and therewith construction work of the CWP 4 in the CWP construction space 10 and of a base mat 7 on the MMR 6 can be performed in parallel. Therefore, a construction schedule of whole turbine building can be substantially shortened and also a construction period of whole nuclear power station can be substantially shortened.
