The present invention relates to an anticorrosive coating structure of JETTY P ILE which is used as a substructure of a port facility. Conventionally, jetty piles located on the surface of water are prevented from being severely corroded by splashing and tidal areas due to repetitive action of water and air exposure. In order to prevent breakage due to impact or impact with a patent, a "corrosion-resistant enclosure for a structure or a molding method thereof" has been known as Japanese Patent Application Laid-open No. 53-80743, but it is on the outside of the pile and on one side It is characterized in that the tongue is formed and the other side of the outer shell formed of the request is joined to the other side, and only the filling material of the foamed synthetic resin is filled in the inside, and its drawback is that the tongue is sandwiched between the demands and the fastening operation is performed. Not easy, of course, the fastening state is not strong, so the blue There is a possibility that it will be easily removed from this request, and the shock absorbing effect by the foamable filler is exhibited well. However, the synthetic resin, which is a filler, has no strong adhesiveness to the wet surface of the steel pipe pile surface, so it is fine between the outer peripheral surface of the pile and the inner surface of the synthetic resin. Because of the presence of gaps, the pile surface was always in contact with moisture and oxygen in the atmosphere, which continued to promote corrosion.

In addition, when the synthetic resin is hardened, the port underwater where the proper environmental temperature is not maintained is cracked due to heat when hardening, and the corrosion effect is very insufficient due to oxidation corrosion due to the gap, which shortens the service life of the pile. In addition, the existing widely used epoxy coating method has the defect that the corrosion of steel surface is drastically accelerated due to the impact and vibration of driftwood, which is blue or floating, or the toxicity of various fish and shell products. The mortar and concrete jacket method continued to promote corrosion due to the low adhesiveness in the areas of contact with the dark salt layer and the wet surface.

In view of the above-described conventional problems, the present invention has the highest corrosion at the low tide level ((+-) 0.00 ~ (-) 1.00m) as shown in FIG. Apply primer PASTE, a petrochemical-based anticorrosive material with excellent adhesion to the outer surface of jetty pile up to the concrete beam, and wrap anticorrosive tape of PETRALATUM component on it to prevent the penetration of moisture. After forming the intermediate coating layer as a PVC sheet or a good cushioning foam (PE) to prevent the impact of blue and external impacts and the attachment of fish and shellfish, and to protect the anticorrosive materials, it is possible to make an effective effect. (Fber glass) and synthetic resin laminated to fasten with F, R, P cover with excellent corrosion resistance and impact strength, but forming flanges on F, R, P cover Geotinde one so as to maintain the easy and rigid clamping state by this will be described in detail in the accompanying drawings as follows.

The outer surface of the jetty pile 1 is covered with F, R, and P covers 5 and 6, and the surface of the jetty pile 1 is composed of a compound compound of antirust petrolatum, tannic acid and inert silica. (2) and coat the anti-corrosive nonwoven fabric tape (3) of the petrolatum component, and then the synthetic resin (P, V, C) sheet (4) is wound, and one end of the cover (5) bolts 501, The flange 502 is formed at the other end, and the hole 601 and the flange 602 are formed at the other cover 6 to be fastened with the bolt 7 and the nut 8 of the anticorrosive.

Reference numeral 9 is a concrete beam.

In this way, the present invention does not permanently evaporate and harden on the surface of the jetty pile, and when it adheres to the metal surface in water, it forms a chemical film of iron tannic acid on the iron surface to completely remove moisture from the surface of the pile. A petrochemical-based anticorrosive petroleum-based antirust petroleum-based anti-rabbit primer (tan), a paste composed of inert silica and a paste (2) was first arrived to form a chemical film called iron tannic acid, followed by rust-resistant petrolatab. Since the chemical coating layer is covered by coating the anticorrosive tape (aka BENSOTAPE) in which the compound is impregnated with the nonwoven fabric, it prevents the infiltration of fine gold (CRACK) and prevents the penetration of moisture. Prevent the damage of anticorrosive agent and damage from fish and shellfish In order to maintain the outer side of the P, V, C seat (4) and the F, R, P cover (5) (6) that is responsible for the role of the cushion is secured by fastening the semi-permanent anticorrosive effect can be expected.

In addition, covers 5 and 6 have different diameters because adjustment flanges are installed so that they can be easily adjusted even if the thickness of the tape (2), P, V, C sheet (4) decreases or increases depending on the construction site. There is no need to prepare the cover 5 (6).

This design has excellent anticorrosive effect, but the corrosion resistant material is closely adhered to the outer circumferential surface of jetty pile in water and water, so it is easy to install underwater and water. There is an effect that can be effected permanently by implementation.
