<P>PROBLEM TO BE SOLVED: To provide a filling method for an underground cavity to secure stable ground by using a filling material that prevents a cavity between a filled part and a ground portion right below the filled part from occurring even if ground subsidence progresses again and has excellent followability to ground movement. <P>SOLUTION: In a filling method for an underground cavity formed due to ground subsidence or ground outflow, a fluidized material is used as the filling material, which includes sands as its main material and is not solidified even after filling. <P>COPYRIGHT: (C)2012,JPO&INPIT |
