PROBLEM TO BE SOLVED: To provide a spraying method that is capable of preventing a slope face from being unstable because of sediment outflow at a natural ground part caused by infiltration of rainwater from a gap formed at a part of a joint filler by thermal contraction of a spray material and makes it possible to easily install the joint filler, and the joint filler used for the spraying method.SOLUTION: A spraying method comprises: a process of disposing, on natural ground (G), a joint filler in a cross-sectional shape (T-shaped cross-sectional shape) having a part (101) extending in a longitudinal direction (direction vertical to a slope face) and parts (102) extending in lateral directions (directions horizontal along the slope face: directions orthogonal to the longitudinal direction); a process of holding (temporarily fixing) the joint filler (100) to the natural ground (G) by using a pin-shaped member (103: fixing pin) penetrating a part (102) extending in the lateral direction of the joint filler (100); and a process of spraying a spray material (M). |
