METHOD FOR CONSTRUCTING CAST-IN-PLACE PILE

PROBLEM TO BE SOLVED: To provide a method for constructing a cast-in-place pile, which can increase a force of friction against an inner surface of an excavated hole, and which facilitates the checking of a constructed state of that means. SOLUTION: This method for constructing the cast-in-place pile includes: an outer-layer-of-pile insertion step of inserting an outer layer 1 of the pile, made of a tubular woven fabric 11 and having rigid thermoplastic resin layers (14 and 15) formed on at least either of inner and outer surfaces constituting the outer layer of the pile, into the excavated hole 25; and an expansion step of heating the outer layer 1 of the pile from the inside of the outer layer 1 of the pile inserted into the hole 25 and of expanding the outer layer 1 of the pile toward an inner peripheral surface of the hole 25.
