Abstract

Purpose: The purpose of the study is to strengthen durability, secure safety, and reduce the economic burden by identifying the causes of deterioration in durability of existing PE pontoon structures (natural factors, design and construction problems, and materials and maintenance factors) and presenting directions for improvement of materials used. Research method (manufacturing method) : It is a research method (manufacturing method) on high-strength pontoon structures with strong high strength bolts and nuts with strong horizontal and vertical bonding structures between pontoon blocks, respectively, using high-strength polyethylene /polyaramid/teflon resin mixtures as pontoon materials.Research Results : It is a high-intensity sea-level pontoon structure that does not cause the pontoon structure to unravel, destroy, and disengage from the coupling device even due to waves, typhoons, and other collision torsions of floating objects floating on the sea.Conclusion : By improving the pontoon material and bonding method of this study, quality and safety were ensured by always maintaining high strength quality, improved bonding of connections, durability, corrosion resistance, maintenance, reduction of environmental impact, aesthetic perspective, and durability deterioration factors.
