SEAWATER CORROSION-PREVENTING REINFORCED CONCRETE PILE STRUCTURE BASED ON SEMIPERMEABLE MEMBRANE
Abstract Disclosed is a seawater corrosion-preventing reinforced concrete pile structure based on a semipermeable membrane. The pile structure includes: a pile body, along 5 which main reinforcing steel bars are arranged in the longitudinal direction; a semipermeable membrane, which covers the outer surface of the pile body and is used for filtering chloride ions in seawater; a protective layer, which covers the outer surface of the semipermeable membrane; and end plates, which are arranged at two ends of the pile body. The pile structure is simply provided with a semipermeable 10 membrane, and the surface of the semipermeable membrane is covered by a protective layer. Thus, the anti-corrosion ability of a concrete pile to chloride ions in the seawater environment is improved, and seawater is blocked from reaching the inner area of the pile structure via microcracks in concrete, thereby enhancing the oxidation resistance and corrosion resistance of the concrete of the pile body and prolonging the 15 service life of the reinforcing steel bars. Hence, the concrete of the pile body can work for a long time without damage, thereby improving the durability of a marine structure. Besides, it is convenient for construction, and working procedures and construction costs are reduced. Fig. 1 Fig. 2
