PROBLEM TO BE SOLVED: To provide an execution method of a fireproof structure for water pipe protection low in its production cost, easily applicable to a water tube wall having a bent portion, and stably durable even under a high temperature atmosphere. SOLUTION: An execution method of a fireproof structure for water pipe protection comprises an execution step in which at least a concave portion of a bent portion 24 of a water tube wall 26 installed in incinerators or boilers is buried underground using a castable refractory 12 such that a wall surface of the water pipe wall facing a high temperature atmosphere becomes almost flat, and an execution step in which a refractory tile 13 having an approximately flat shape is installed on the surface of the castable refractory 12, and is characterized in that the refractory tile 13 is fixed by engaging a latching member 15 pre-installed in a water pipe 10 with a concave portion formed in the refractory tile 13, and the refractory tile 13 is adhered to the water pipe wall 26 using an adhesive such as mortar.
