【発明の詳細な説明】 ［産業上の利用分野］ 本発明は、桟橋等の港湾構造物を防食するための施工法
及びこれに用いる防食パネルに関する。Description: [Industrial field of application] The present invention relates to a construction method for preventing corrosion of a harbor structure such as a jetty and a corrosion-preventing panel used for the same.
［従来の技術］ 桟橋の鋼管支柱や埋め立てに用いられる鋼矢板等の港湾
構造物は、その干満域、飛沫域及び海中部分がマクロ電
池の作用により集中的に腐食することが知られている。[Prior Art] It is known that the tide area, splash area and subsea area of a port structure such as a steel pipe support of a jetty or a steel sheet pile used for landfill is intensively corroded by the action of a macro battery.

No. 130827 and No. 130827, the surface of the structure is subjected to a surface treatment by a sand blast method or a photo jet method, and then a lining agent such as an underwater curing type epoxy resin is applied on the structure for anticorrosion treatment. In addition, since the spray coating means cannot be used in the undersea portion of the structure, the diver dives and manually coats the epoxy resin in which the curing agent is added to the main component.
［発明が解決しようとする課題］ しかし、従来の防食施工法にあっては、海水の浸透や耐
久性の点からライニング剤の厚さを少なくとも3mm以上
必要とするので、海中で何度も重ね塗りしなければなら
ず、手間がかかると共にエポキシ樹脂のコストも高くな
る欠点がある。[Problems to be solved by the invention] However, in the conventional anticorrosion construction method, since the thickness of the lining agent needs to be at least 3 mm or more from the viewpoint of permeation of seawater and durability, the lining agent may be repeatedly overlaid in the sea. It has to be applied, which is troublesome and the cost of the epoxy resin is high.

Then, a corrosion-resistant soft panel having a plurality of holes is pressed and attached until the lining agent protrudes from the holes.
また、第二の目的を達成するため、本発明では、前述の
防食用軟質パネルに孔及び凹凸面を設けている。Further, in order to achieve the second object, in the present invention, the above-mentioned soft panel for corrosion protection is provided with holes and uneven surfaces.

The lining agent enters and seals. Since the flexible panel has flexibility, it can follow the structure even if the surface of the structure is not completely flat, and the thickness of the lining agent can be reduced by the amount of the panel.

ーラで簡単に塗布することができる。In the anticorrosion area of the harbor structure 1, the surface scribe and rust are removed by the sandblast method or the water jet method, and the underwater curing type lining agent 2 is applied after the surface treatment. The lining agent 2 itself is the same as the conventional product in which the curing agent is added to the main component of the epoxy resin, but the coating thickness is 1.5 mm or less, that is, half or less of the conventional thickness. In this embodiment, a commercially available AC Marine Coat (trade name) is used as the lining agent 2, which a diver can easily apply with a brush or a roller.

凸５が形成されている。Next, the soft panel 3 having corrosion resistance is sequentially pressed and attached to the surface of the lining agent 2. The soft panel 3 is an FRP material, but is more flexible and bendable than general FRP, and its surface is coated with a resin having good weather resistance. In this example, a continuously molded FR
P A super soft sheet is cut in advance to a length of about 30 cm and a thickness of about 0.8 mm to make a large number of soft panels 3. Each soft panel 3
A plurality of holes 4, 4 are provided on the inner surface of the inner wall, and fine irregularities 5 are formed on the inner surface thereof.

トやシールが不要となる。Therefore, when the soft panel 3 is strongly pressed onto the lining agent 2, the inner concave-convex surface 5 (FIG. 2) improves the adhesion and the lining agent from the holes 4, 4 of the panel and the joint 6 between the panels. 2 is extruded. Therefore, each hole
The lining agent 2 hardened in 4, 4 plays a role of fixing the soft panel 3 on the lining agent 2, and the lining agent 2 hardened in the joint 6 performs a sealing action, so that a bolt or a seal is not necessary.

果がある。[Effects of the Invention] As described in detail above, according to the anticorrosion construction method of claim (1), since the soft panel is attached in a pressed state on the lining agent applied to the structure, the lining agent is applied repeatedly. It is not necessary to do so, and the labor and cost are reduced. In addition, since the lining agent is filled in the joints and holes between the soft panels, there is an effect that sealing is performed at the same time.
