Abstract
PURPOSE: To provide an easy and safe removal of the specified freeezing pipe upon completion of the freezing work after non-freezed ground portion surrounding an outer circumference of the freezing pipe is freezed upon completion of the freezing work by circulating hot water in the freezing pipe and forcibly defreezing the freezed soil surrounding the outer circumference of the pipe.
CONSTITUTION: Freezing work is performed by using the freezing pipe P, the freezed soil F is arranged to complete the freezing work. Then, the thermal insulator 2 provided at the top and inside of the outer pipe 1 is removed and the coolant is circulated from the inner pipe 3. The freezed soil Fa is made at the outer circumference having the thermal insulator 2 of the pipe 1 by circulating the coolant, the pipe 1 and the freezed soil Fa are freezed, and the entire outer circumference of the pipe is freezedly adhered to the freezed soils Fa and F. Then, under this condition, hot water is circulated in the pipe 3, the freezed soil surrounding the entire outer circumference of the pipe 1 is forcedly defreezed to form a defreezed soil f and then releasing a freezed adhesion between the pipe 1, and the freezed soils F and Fa. Then, the pipe P is removed by a vipro pile hammer etc.
