STRUCTURE LIFTING METHOD POSSIBLE TO BE RE-LIFTING USING PILE MEMBER

摘要

A lifting method of a structure using a re-liftable indenter is provided to lift up the settled structure by installing a pile, a top supporting body and a lift support plate to the inside of a structure having a limited space and to re-lift up the settled structure at need. A lifting method of a structure using a re-liftable indenter comprises the steps of cutting of the surface of a base plate(110) of a structure partially and forming a perforation on the base plate of the structure using a perforator, installing projecting members such as a deformed bar or an anchor bolt in the perforation, inserting a setting member to the inside of the perforation to make a fabric reinforcement(220) of the setting member put over the projecting members, unifying the setting member with the structure by placing filler such as mortar to the inside of the perforation and the base of the structure and hardening the mortar, inserting and setting an indenter(400) such as a concrete pile to the inside of a guide pipe(210) of the setting member, anchoring a top supporting body(300), composed of an upper plate(310) and a support bar(330) coupled to the upper plate by a connecting nut(320) and extended downward, on the setting member, installing a head reinforcement plate(340) on the head of the concrete pile selectively and installing an indentation unit(500) such as a hydraulic cylinder on the top of the head reinforcement plate, coupling the top of a vertical bar of the setting member with the support bar of the top supporting body using a connecting nut(350), setting many indenters to the lower ground(700) of the structure to lift up the settled structure to the wanted height, installing a lift support plate to the setting member which surrounds the indenter to keep the structure at the lifted state, dismantling the lift support plate from the setting member by unfastening a fastening nut of the installed lift support plate and re-installing the top supporting body using a connecting nut and installing an indentation unit between the top supporting body and the concrete pile and operating the indentation unit to lift up the settled structure again, and after re-lifting, dismantling the re-installed top supporting body and installing the lift support plate.
