PURPOSE: A pultruded pipe for grouting is provided to have enough resistance against vertical load and internal pressure and to use widely for industry with excellent corrosion resistance, heat resistance, cold resistance and wave permeability. CONSTITUTION: The pultruded pipe for grouting(100) comprises the steps of piling up roving impregnated in a compound composed of stitch mats woven with glass fibers, resins and a mixture many times, covering up the outermost side with a continuous strand mat, forming one pultruded pipe body by unifying the stitch mats, the roving and the continuous strand mat using the compound by heating, forming many through holes on the body to discharge injection materials, installing a one-way operating valve to the through hole, and installing many spacers(180) on the body to prevent the valve from getting clogged when driving in a pipe.
