PROBLEM TO BE SOLVED: To provide a grouting method for grouting a grouting material only in a portion effective for reinforcing the natural ground by using a packer collectable from the inside of a bored tube after the grouting material is pressingly fed therein and a movement prevention device easily preventing the movement of the packer by the press-feeding of the grouting material therein.;SOLUTION: This grouting packer 14 comprises a packer body 18 and a seal bush 20. The packer body 18 comprises a plurality of grouting tubes 22, a tubular body 26 to which an expansion body 24 is fixed to the outer peripheral surface thereof, a pressure supporting tube 28, and a cover 30 closing the other end of the tubular body. The outline of the seal bush 20 is formed in a tapered shape, the grouting tubes 22 are inserted therein and loosely inserted into the bush mounting hole 30a of the cover 30. The seal bush 20 is formed of rubber, and its tapered narrow closed side is loosely inserted into the bush mounting hole 30a so that the seal bush 20 can be easily released from the cover 30.;COPYRIGHT: (C)2007,JPO&INPIT
