INJECTION PACKER FOR GROUND SUBSIDENCE RESTORATION, RECLAMATION METHOD AND APPARATUS FOR GROUND SUB

The present invention relates to an injection packer for restoring ground subsidence and a method and an apparatus for restoring the ground subsidence using the same. The injection packer of the present invention comprises : a cylindrical holder made of synthetic resin or a metal material and having an injection hole formed in an upper portion, wherein a mixed-type inflator, in which first liquid and second liquid are mixed, passes through an upper portion of a membrane compressed body attached at a lower end and is injected into the membrane compressed body; and the peak-shaped membrane compressed body formed on a lower end, configured to have an over-layered structure, such that the mixed-type inflator, which is a filling material for inflation including the first liquid and the second liquid therein, can be contained, wherein the mixed-type inflator is injected into the interval of each layer of the structure, and expanded to fit a size of the pores disposed on a lower portion so as to fill the pores in an unfolding way. According to the present invention, it is possible to perform emergency restoration without opening the road pavement at the site, in which pores are generated according to the size and material characteristics of the pores at a lower portion of the ground, by using the swelling phenomenon occurring when a straight-type injection packer is injected. It is possible to efficiently perform restoration by utilizing the existing restoration data when the pores, in which the emergency recovery is performed, are restored. As a marker, which provides information based on an RFID tag, is mounted additionally on an upper surface, in which the injection parker is constructed, it is possible to reinforce the area, in which the injection parker is mounted, and to accurately readjust a supply amount of the mixed-type inflator or the like based on the big data when an upper portion of the pavement is repaired.COPYRIGHT KIPO 2018
