UNDERFLOOR REINFORCEMENT METHOD AND UNDERFLOOR REINFORCEMENT STRUCTURE
To provide an underfloor reinforcement method or the like increased in strength in a reinforced place.SOLUTION: The underfloor reinforcement method for reinforcing an underfloor by filling a cavity 3 between a ground 2 and a floor 1 comprises: a step of forming a through-hole 4 connected to the cavity 3 in the floor 1; a step of inserting a rod-like drill from the through-hole 4 into the cavity 3 side to dig in the ground 2, and forming a longitudinal hole extending down from the cavity 3 directly below the through-hole 4; a step of supplying a liquid ground reinforcement 5 from the through-hole 4 into the cavity 3 and the longitudinal hole; a step of inserting the drill from the through-hole 4 into the longitudinal hole and stirring the ground reinforcement 5 in the longitudinal hole to permeate the ground reinforcement 5 through soil around the longitudinal hole, and retaining the shape of the longitudinal hole through curing action of the ground reinforcement 5; a step of supplying a foaming resin from the through-hole 4 to fill the cavity 3 and the longitudinal hole; and a step of closing the through-hole 4 after the cavity 3 and the longitudinal hole have been filled with the foaming resin.SELECTED DRAWING: Figure 6
【課題】補強箇所の強度が向上した床下補強方法等の提供。【解決手段】本発明の床下補強方法は、地盤２と、床１との間の空洞３を埋めることで床下を補強する床下補強方法であって、床１に、空洞３と繋がる貫通孔４を形成する工程と、貫通孔４から空洞３側に棒状のドリルを挿入して地盤２を掘り下げ、貫通孔４の真下に、空洞３から下方に延びた縦穴を形成する工程と、貫通孔４から空洞３及び縦穴に液状の地盤強化剤５を供給する工程と、貫通孔４から縦穴にドリルを挿入して縦穴内の地盤強化剤５を攪拌することにより、地盤強化剤５を縦穴の周囲の土壌に浸透させて、地盤強化剤５による硬化作用により、縦穴の形状を保持させる工程と、その後、貫通孔４から空洞３及び縦穴を埋めるように、発泡性樹脂を供給する工程と、空洞３及び縦穴が、発泡性樹脂で埋められた後、貫通孔４を塞ぐ工程とを備える。【選択図】図６
