FROZEN SOIL FORMING DEVICE AND FROZEN SOIL CONSTRUCTING METHOD
To provide a frozen soil forming device and a frozen soil constructing method allowing the selection of a depth region of a ground to be cooled while suppressing installation space.SOLUTION: A frozen soil forming device 1 comprises a freezing tube 3 embedded in a ground G and provided with a refrigerant inlet pipe 7 and a refrigerant outlet pipe 9 at an upper end side. The freezing tube 3 includes: an outer tube portion 21 provided with the refrigerant outlet pipe 9 at an upper end side and having a bottom portion on a lower end side; and a short inner tube 23 and a long inner tube 25 including supply ports 23a, 25a disposed in a hollow portion 21h of the outer tube portion 21 and supplying a refrigerant from the refrigerant inlet pipe 7 into the hollow portion 21h of the outer tube portion 21. Positions of the supply ports 23a, 25a in a depth direction are variable.SELECTED DRAWING: Figure 2
【課題】設置スペースを抑えながら、冷却する地盤の深度領域を選択可能とする凍土形成装置及び凍土造成方法を提供する。【解決手段】凍土形成装置１は、地盤Ｇに埋入され上端側に冷媒入口管７及び冷媒出口管９が設けられた凍結管３を備える凍土形成装置１であって、凍結管３は、上端側に冷媒出口管９が設けられ下端側に底部をもつ外管部２１と、外管部２１の中空部２１ｈ内に配置され冷媒入口管７からの冷媒を外管部２１の中空部２１ｈ内に供給する供給口２３ａ，２５ａを含む短尺内管２３及び長尺内管２５と、を有し、供給口２３ａ，２５ａの深さ方向の位置が可変である。【選択図】図２
