Provided are an anchor pin for placing shotcrete and fixing a textile grid and a method of constructing textile grid reinforced shotcrete using the same, wherein the anchor pin allows a textile grid reinforcement to be precisely disposed at a required position and, when shotcrete is placed, prevents a textile grid reinforcement from moving due to a driving pressure for precise construction so as to increase durability and safety of the concrete structure, allows primary and secondary shotcrete to be constructed while placing thicknesses thereof are visually checked so as to increase precision of construction, and allows the textile grid reinforcement to be disposed and fixed to accurately correspond to a shape of the concrete structure even when a lower portion of a slab, a wall, and a structure with a curved surface, such as a lining of a tunnel, are built.
