GROUND IMPROVEMENT DEVICE, AND GROUND IMPROVEMENT METHOD
To easily recover sludge in ground improvement.SOLUTION: A ground improvement device for injecting a solidification material into the ground from a rotary injection pipe 310 and establishing an improvement body by a high pressure injection agitation method includes: a seal pipe 210 provided so that its outer peripheral surface is brought into close contact with the ground; and a sludge liquid sending pipe connection part 211 that has a rotary injection pipe insertion hole to which the rotary injection pipe 310 is inserted in a sealed state provided on its upper part, is connected to the upper part of the seal pipe 210, is connected with a sludge liquid feeding pipe 212, and supplies the sludge rising in the seal pipe 210 in the sealed state to the sludge liquid feeding pipe 212.SELECTED DRAWING: Figure 4
【課題】地盤改良の際に排泥を容易に回収できるようにする。【解決手段】回転噴射管３１０から固化材を地盤中に噴射して高圧噴射撹拌工法により改良体を造成する地盤改良装置は、外周面を地盤に密着させて設けられるシール管２１０と、上部に回転噴射管３１０が密閉状態で挿通される回転噴射管挿入孔が設けられ、上記シール管２１０の上部に接続されるとともに、排泥送液管２１２が接続され、シール管２１０内を上昇する排泥を密閉状態で排泥送液管２１２に送液する排泥送液管接続部２１１とを備える。【選択図】図４
