CONSTRUCTION METHOD FOR POST FOR PREVENTING SUBSIDENCE OF QUARRYING TRACE CAVITY

摘要

PROBLEM TO BE SOLVED: To provide a construction method for a new artificial post in place of an eroded existing stone pillar to prevent the subsidence of a quarrying trace cavity.;SOLUTION: A pack 6 formed by sewing or bonding a corrosion-resistant synthetic resin sheet with a low elastic modulus with glass fiber or the like woven therein, into post shape is used instead of a form and hung in a folded state in a cavity from an auger hole, and incineration ash mortar subjected to detoxification treatment is force-fed and filled into the pack so as to be restored into post shape, which is cured and solidified. In an area where the erosion of the stone pillar extends in a wide range, a temporary pipe scaffolding 8 and a sheet are carried into the cavity, and the sheet is fixedly laminated in contact with the interior of a skeleton formed of the pipe scaffolding, to form a pool. The mortar is filled in the pool and cured and solidified to constitute the post of large cross-sectional area.;COPYRIGHT: (C)2004,JPO
