WATER LEAKAGE PART-FREEZING DEVICE AND WATER STOPPING METHOD OF WATER LEAKAGE PART

摘要

PROBLEM TO BE SOLVED: To provide a press type simplified freezing device which can be used for stopping a small-scale water leak from the ground or a structure even when a water leakage part is not flat or even in a narrow space, is simple and lightweight, and has high cooling efficiency, and a water stopping method using the freezing device.;SOLUTION: A plurality of freezing pipes 9 are installed circumferentially around the lower end outer periphery of a pressure container 3 of the freezing device 1, and combined with the pressure container 3 by a band 15 at several points in the circumferential direction. The freezing pipes 9 are covered with a heat conductive material 17, and when a refrigerant 25 flows into a refrigerant introduction pipe 13, the refrigerant 25 flows through the inside of the freezing pipes 9 around the pressure container 3. The freezing pipes 9 are cooled by the refrigerant to cool and freeze a part to be cooled through the heat conductive material 17.;COPYRIGHT: (C)2009,JPO&INPIT
