摘要

PROBLEM TO BE SOLVED: To provide a method for forming an end of backfill soil, which enables the backfill soil to maintain stability even when a form is removed after a lapse of a desired curing period.;SOLUTION: A form supporting carriage 10 comprises a carriage, an arc-shaped form along a lining body 5, and an inclination device for inclining the form. When backfill soil 4 is backfilled, firstly, a form installation step for installing the form is performed. In this step, the form is inclined at a predetermined angle of repose. Subsequently, a laying step of backflling new backfill soil 4 between the form and the existing backfill soil 4 is performed. Finally, a removal step of removing the form is performed a predetermined number of curing days after the backfill soil 4 is laid in the laying step.;COPYRIGHT: (C)2012,JPO&INPIT
