FACILITY FOR PRECOOLING GROUNDWATER AND METHOD FOR PRECOOLING GROUNDWATER

摘要

PROBLEM TO BE SOLVED: To provide a facility capable of efficiently forming a frozen soil wall in a foundation on which a structure is installed, by reducing inhibition of cryogenic heat transfer efficiency caused by groundwater.;SOLUTION: The facility for precooling groundwater of the present invention is a facility for precooling groundwater in the foundation to form a frozen wall, including a production section for producing a cooling medium by cooling groundwater drawn from an underground water channel, and a storage section for storing the cooling medium in the ground, communicating with the underground water channel. The cryogenic heat from the stored cooling medium reduces the temperature of the groundwater in the underground water channel.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2018,JPO&INPIT
