초록 ▼

An apparatus and method of freezing a large volume of ground for tunnel construction and the like utilizing liquified nitrogen is described. The apparatus consists generally of a series of freeze pipes embedded in the ground, each of the freeze pipes consisting of a conductor tube and an inner header tube. The header tube of each of the succeeding freeze pipes in the series have discharge holes of a predetermined cross-section so that greater control of gaseous and liquified nitrogen pressure can be maintained throughout the system. By means of this method and apparatus more accurate control of ground freezing can be made by merely controlling the inlet liquified nitrogen pressure and the exhaust gaseous nitrogen temperature.

대표청구항 ▼

A method of freezing ground by passing nitrogen through a plurality of freeze pipes connected in series and embedded in the ground, each of said freeze pipes consisting of a conductor tube and a header tube coaxially mounted in the conductor tube and extending therein substantially the length of said conductor tube, the steps comprising: a. continually passing liquid nitrogen under pressure into the header tube of the first of said freeze pipes and discharging the nitrogen from the bottom of said header tube into the lower end of the conductor tube of the first of said freeze pipes and substantially filling said conductor tube with liquid nitrogen. b. passing the nitrogen overflow from the conductor tube of the first of said freeze pipe into the header tube of the second of said freeze pipes and then discharging liquid and vaporized nitrogen from said header tube into the conductor tube of the second of said freeze pipes through a plurality of apertures in said header tube, said apertures having a total cross-sectional area equal to at least 200 percent of the cross-sectional area of the header tube; c. and discharging the substantially vaporized nitrogen from the upper end of the conductor tube of the second of said freeze pipes, the passage of nitrogen through the plurality of freeze pipes being at such a rate that the nitrogen discharged from said freeze pipes has a temperature at least as low as -80° C.
