The present invention relates to a method for constructing an underwater pipe protective means and a fixed and protecting bag for an underwater pipe used therefor. According to the present invention, the fixed and protecting bag installed on an ocean floor, a river bed or the like is cured to match an exterior shape of the underwater pipe and a geographical feature of the floor, thereby preventing abrasion by soils, which is caused by a speed of a moving water, preventing a loss of the fixed and preventing bag from an anchor or a fishing gear, and preventing a friction between the underwater pipe and a fixed part, Therefore, a life span of the underwater pipe can be extended. The method for constructing the underwater pipe protective means comprises: a step of preparing the fixed and preventing bag having a solid formulation storage space (110) formed on an interior thereof and closed and a solid formation injection opening (120); a step of injecting a solid formulation (9) to the interior of the fixed and protecting bag; and a step of inputting the fixed and protecting bag into a water before the injected solid deformation (9) to be completely cured to cover an underwater pipe (p) installed on an underwater floor (G). |
