SITE CONCRETING METHOD IN CONSTRUCTING BASEMENT USING WATER SHUTOFF SACK

摘要

PURPOSE:To have waterproofing in compliance with diversified dimensions by inserting a water shutting sack in an excavated hole, placing bottom concrete, putting a waste frame, installing separating member for wall part and reinforcing bars, and then placing concrete for the wall part. CONSTITUTION:A water shutting sack 1 is formed from styrole foam consisting of an internal protecting member 11 and external protecting member 12. Then a waste frame putting plate 3 with a waste frame putting dimensioned member arranged is put in place, and bottom concrete 4 is placed, and after its hardening, a waste frame 5 is put. Then a separating member 6 for wall part and reinforcing bars and incorporated, and an internal frame 7 is assembled, and the parts outside the sack 1 are refilled. Concrete is placed between the frame 5 and the internal frame 7, and after its hardening, the internal frame 7 is removed, and a ceiling beam and upper concrete are placed. This acomplishes waterproofing in compliance with site situation through the use of water shutting sack.
