METHOD FOR CONSTRUCTING VERTICAL SHAFT TEMPORARY WALL

PROBLEM TO BE SOLVED: To provide a method for constructing a vertical shaft temporary wall capable of setting pile members in a building position of an excavation pit with an erected attitude to form an area of a fixed shape allowing the passing of a shield machine between the pile members. SOLUTION: The method for constructing a vertical shaft temporary wall comprises a pile member building step of raising a building pile member 10A with a second pile member 17 laid down, and building the building pile member 10A in an excavation pit 13 while removing a support plate 18 from the first and the second pile members 16 and 17; a joint pile member building step of building a joint pile member 24 from above the first pile member 16 after building the building pile member 10A in a predetermined position in the pile member building step; and a steel wire drawing step of separating first to fourth steel wires 19, 20, 21 and 22 from a steel wire first support member 23 after curing soil mortar 14, and drawing the steel wires 19, 20, 21 and 22 from the excavation pit 13.
