摘要

PROBLEM TO BE SOLVED: To simplify on-site construction work without damage to reliability and reduce a construction period, when a sewage tank 1 such as a pump unit A and a septic tank is buried in ground.;SOLUTION: A foundation concrete plate 4 and an upper concrete plate 10 are premanufactured in a factory; a downside casing 2 of the sewage tank 1 is placed on the concrete plate 4; and an upside casing 3 is placed on the downside casing 2 and fixed by a hold-down fitting 5 and coupling members 6, 6, etc. A supporting fitting 12 and the concrete plate 10 are mounted at an upper end of the upside casing 3, so that the pump unit A can be assembled (a unit assembling process). On the job site for burial, a prescribed place on the ground is excavated for the formation of a burying pit H (an excavating process); and the pump unit A, which is conveyed from the factory, is housed and installed in the burying pit H so as to be made approximately horizontal (an installation process).;COPYRIGHT: (C)2004,JPO
