摩し、前記防汚材を露出させることを含む。(Means for solving the problems) The present invention is a method for preventing stains on the walls of concrete structures or steel plates submerged in seawater, and the present invention is a method for preventing stains on walls of concrete structures or steel plates that are submerged in seawater. The method includes applying the antifouling material to the wall surface to form a base layer, and after curing the base layer, polishing the surface of the base layer to expose the antifouling material.

る銅または銅合金から銅イオンが溶出し、海洋生物の付
着を防止する。When the surface of the base layer is polished by a grindstone, sandblasting, or other means, the antifouling material is exposed from the base layer. When the antifouling material is exposed and the wall surface is submerged in seawater, copper ions are eluted from the copper or copper alloy, which is the main component of the antifouling material, and prevent marine organisms from adhering to it.

面が塗料に覆われているため、防汚効果は期待できない
。しかし、本発明では、基層を研摩して防汚材を露出さ
せているため、防汚効果を速やかに、かつ確実に得るこ
とができる。When a paint containing an antifouling material is applied, no antifouling effect can be expected because the surface of the antifouling material is covered with the paint. However, in the present invention, since the base layer is polished to expose the antifouling material, the antifouling effect can be quickly and reliably obtained.
防汚材を含有する塗料の壁面への塗布や、基層の表面の
研摩には大間りな設備は不要であり、コスト高となるの
を抑えることができる。No extensive equipment is required for applying paint containing an antifouling material to the wall surface or polishing the surface of the base layer, and high costs can be suppressed.

吹き付け、ライニング層に付着させることを含む。The present invention also provides a method for antifouling a wall surface of a concrete structure or a steel plate submerged in seawater, the method comprising: fixing a lining material that has adhesive properties when not dry to the wall surface to form a lining layer; The method includes spraying an antifouling material based on copper or a copper alloy onto the lining layer to adhere to the lining layer before the layer dries.

イニング層に付着させた壁面を海水中に没すると、防汚
材の主成分である銅または銅合金から溶出する銅イオン
の量か多くなり、高い防汚効果が得られる。When the antifouling material is sprayed and adhered to the lining layer, the area of the antifouling material that comes into contact with seawater is larger than when the antifouling material is exposed by polishing. Therefore, when a wall surface with antifouling material attached to the lining layer is immersed in seawater, the amount of copper ions eluted from the copper or copper alloy, which is the main component of the antifouling material, increases, resulting in a high antifouling effect. .

面の防汚効果を継続させることができる。On the other hand, the period during which the antifouling effect can be obtained is shortened. However, when the antifouling effect is no longer obtained or when the antifouling effect decreases, a lining material is fixed on top of the antifouling material to form a new lining layer, and this lining layer has an antifouling effect. By spraying the material and adhering it to the lining layer, the antifouling effect on the wall surface can be maintained.

である。If the amount of antifouling material sprayed is constant, it is possible to estimate the degree of antifouling effect after a certain period of time. Therefore, it is possible to carry out antifouling maintenance on the wall surface in a realistic manner.
