Title:
GROUND FREEZING METHOD
Document Type and Number:
Japanese Patent JP2017137703
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a ground freezing method that enables efficient execution of work by carrying out a design by establishing standards required for the execution of the work.SOLUTION: In a ground freezing method of the present invention, carbon dioxide is used as a coolant; a theoretical value (▵Pcal) of pressure damage is computed; a numerical value (estimated value: ▵Pp) corresponding to an actual value of the pressure damage is computed; and various items required for execution of work are computed and determined from the computed estimated value (▵Pp) of the pressure damage.SELECTED DRAWING: Figure 2
