TETRAPOD AND METHOD FOR MANUFACTURING THE SAME

摘要

PURPOSE: A concrete-filled FRP(Fiber Reinforced Plastic) tetrapod and a manufacturing method for the same are provided to facilitate to manufacture without using a separate form and to prevent poor durability due to corrosion and salt damage by seawater. CONSTITUTION: A concrete-filled FRP tetrapod(100) comprises an FRP housing(110) and concrete for filling the housing. The housing is internally formed with a space for filling concrete and is protruded with a plurality of legs(111). The joint of the legs is formed with a stiffener edge which is internally protruded. The stiffener edge comprises a plurality of combining holes for equipping a support bar which separately crosses each leg. The joint is formed with a third combining hole for combining a longitudinal support bar.
