GROUND FREEZING METHOD AND GROUND FREEZING SYSTEM
PROBLEM TO BE SOLVED: To provide a ground freezing method in which a thermal efficiency of coolant is good and a gas phase refrigerant is never discharged in the ground and air.SOLUTION: A ground freezing system has a freezing pipe buried to freeze the ground and coolant circulation piping disposed inside the freezing pipe, and has a cooling device for cooling a carbon dioxide and supply it in the coolant circulation piping since the coolant circulating in the coolant circulation piping is a carbon dioxide. The coolant circulation piping comprises first coolant circulation piping 2A formed with multiple micro-refrigerant flow paths 2Aδ-G, R. A closing member 3 for bringing the multiple micro-refrigerant flow paths 2Aδ-G, R of the first coolant circulation piping 2A into communication with a coolant supply side and a coolant return side is connected to the tip part (ground side end part) of the first coolant circulation piping 2A.SELECTED DRAWING: Figure 3
【課題】冷媒の熱効率が良好であり、気相冷媒が地中や空中に放出されることのない地盤凍結工法を提供する。【解決手段】地盤を凍結するために埋設された凍結管と、凍結管の内部に配置される冷媒循環用配管を有し、冷媒循環用配管内を循環する冷媒が二酸化炭素であり、二酸化炭素を冷却して冷媒循環用配管に供給する冷却装置を有し、冷媒循環用配管は複数の微小冷媒流路２Ａδ−Ｇ、Ｒが形成されている第１の冷媒循環用配管２Ａを含み、第１の冷媒循環用配管２Ａの先端部（地中側端部）には、第１の冷媒循環用配管２Ａの複数の微小冷媒流路２Ａδ−Ｇ，Ｒを冷媒供給側と冷媒戻り側とに連通する閉塞部材３が接続されている。【選択図】図３
