Document Type and Number:
Japanese Patent JP6783692
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for constructing a wide block, a method for forming a movable water-stopping barrier and a refrigerant circuit for water-barrier formation, each of which can freeze each continuous plural construction units as one group of water-stopping barrier and also can move the water-stopping barrier every one construction unit.SOLUTION: A method for constructing a wide block, a method for forming a movable water-stopping barrier and a refrigerant circuit for water-stopping barrier formation are respectively characterized by: in a following shield tunnel 7, constructing a first refrigerant circuit corresponding to one or more construction units except a construction unit of first plural construction units and a second refrigerant circuit corresponding to a second plural construction units shifted by only one construction unit, reconstructing the first and second refrigerant circuits by alternately moving the first refrigerant circuit and the second refrigerant unit to a span of two construction units, and extending the wide block 15 so as to be integrated refrigerant circuit by alternatively executing a replacement work of plural kind of construction works Q, R, S in the first and second plural construction units, while advancing water-stopping barrier M by one construction unit for the whole of moisture in a natural ground at the outside of a segment of the first and second plural construction units.SELECTED DRAWING: Figure 19
