GROUND FREEZING METHOD AND GROUND FREEZING SYSTEM
To provide a technology that can promote formation of permafrost without injecting chemicals even in grounds where velocity of groundwater flow is relatively fast.SOLUTION: A ground freezing method consists of a process of installing multiple freezing pipes 12, 12 on the ground 10 so as to be aligned in a direction intersecting the flowing direction of groundwater at predetermined intervals from each other, a process of installing a pumping pipe 16 on the upstream side of the groundwater flow from the row of the freezing pipes 12, 12, a process of installing a discharge pipe 18 downstream of the groundwater flow, and a process in which refrigerant is supplied to the freezing pipes 12, 12 to form frozen soil 14a in the ground, and groundwater pumped up from the pumping pipe 16 is discharged into the ground 10 through the water discharge pipe 18. The groundwater discharged from the discharge pipe 18 is discharged in a direction opposite to the groundwater flow.SELECTED DRAWING: Figure 3
【課題】地下水流の流速が比較的速い地盤であっても、薬液の注入を伴うことなく、凍土の形成を促進可能な技術を提供する。【解決手段】地盤10に複数本の凍結管12,12を、相互に所定の間隔をおいて、地下水の流れる方向と交差する方向に並ぶように設置する工程と、凍結管12,12の並びよりも地下水流の上流側に揚水管16を設置する工程と、地下水流の下流側に放水管18を設置する工程と、凍結管12,12に冷媒を供給して地盤中に凍土14aを形成すると共に、揚水管16から汲み上げた地下水を、放水管18を介して地盤10中に放出する工程からなる地盤凍結工法。放水管18から放出される地下水は、地下水流と逆行する方向に放出される。【選択図】図３
