［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。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a construction method for corrosion-proofing port structures such as piers, and a corrosion-proofing panel used therein.
［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 port structures such as steel pipe supports of piers and steel sheet piles used for reclamation are subject to intensive corrosion in their tidal areas, splash areas, and underwater parts due to the action of macro batteries.

As in No. 4972 and No. 130827, the surface of the structure is subjected to surface treatment using a sandblasting method or a water jet method, and then a lining agent such as an underwater curing epoxy resin is coated thereon for anticorrosion treatment. In addition, since spray painting methods cannot be used on the underwater parts of the structure, a dipper is used to hand-paint the epoxy resin by adding a curing agent to the main component.

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。[Problem to be solved by the invention] However, in the conventional anti-corrosion construction method, the thickness of the lining agent needs to be at least 31 cm or more from the viewpoint of seawater penetration and durability. It has the disadvantage that it requires painting, which is time-consuming and increases the cost of the epoxy resin.

の継ぎ目を確実にシールしなければならない。On the other hand, it is widely practiced to cover the corrosion-protected areas of structures with corrosion-resistant FRP covers, but in this case it is necessary to mold the cover according to the shape of each structure, and it is also necessary to mold multiple panels. The seams of each panel must be reliably sealed after being attached to the structure with adhesive.
本発明は、かかる事情に鑑みてなされたものであり、第
一の目的は、ライニング剤の重ね塗りを大幅に少なくし
てその手間とコストを軽減できる港湾構造物の防食施工
法を提供することにある。The present invention has been made in view of the above circumstances, and its first purpose is to provide a corrosion-proofing construction method for port structures that can significantly reduce the number of layers of lining agent and reduce the effort and cost involved. It is in.
また、本発明の第二の目的は、特別なシール手段を要せ

して貼り付けている。[Means for Solving the Problems] In order to achieve the above-mentioned first objective, the anti-corrosion construction method of the present invention provides a surface treatment for the corrosion-protected area of a port structure, and coats the surface with an underwater curing lining agent. Then, a soft anti-corrosion panel with a non-woven fabric adhered to the inner surface is successively pressed onto the lining material.
また、第二の目的を達成するため、本発明の防食パネル

。[Function] According to the configuration of claim (1), when each soft panel is pressed onto the lining agent applied to the port structure, the panel will strongly adhere to the lining agent through the nonwoven fabric, and
The pressure forces the lining agent into the seams of each panel, creating a seal. Because the flexible panel is visible, it follows the surface of the structure even if it is not completely flat, and the thickness of the lining material can be reduced by the amount of the flexible panel.
また、請求項（２）の防食パネルをライニング剤の層の

ローラで簡単に塗布することができる。The corrosion-protected area of the port structure 1 is coated with an underwater curable lining agent 2 after surface oyster shells and rust are removed by sandblasting or water jetting and surface treatment is performed. The lining agent 2 itself is similar to a conventional product in which a curing agent is added to the main ingredient of epoxy resin, but it is sufficient to apply the lining agent 2 to a thickness of 1.5 ms or less, that is, less than half of the conventional lining agent. In this example, commercially available AC Marine Coat (trade name) is used as the lining agent 2, which can be easily applied by a dieper by hand or with a roller.

は、複数の孔５．５が設けられている。This soft panel 3 is made of PRP material, but it is made of general FR material.
It has better flexibility and bending workability than P, and a nylon nonwoven fabric 4 is attached to its surface with an adhesive. In this example, a non-woven fabric 4 with a thickness of about 0.51 is pasted on the surface of a continuously molded super-soft FRP sheet, which measures about 30 cm in length and width and has a thickness of about 0.8 + sm? A large number of flexible panels 3 are formed by ni-cutting. Each flexible panel 3 is also provided with a plurality of holes 5.5.

ボルトやシールが不要となる。Therefore, when this soft panel 3 is strongly pressed onto the lining agent 2, the adhesion is improved by the inner uneven surface 5 (Fig. 2), and the lining agent is applied through the panel holes 5.5 and the seams 6 between the panels. 2 is pushed out. Therefore, the lining agent 2 hardened within each hole 5.5 is transferred to the soft panel 3.
The seam 6 serves to fix the lining material 2 onto the lining material 2.
The lining agent 2 hardened inside performs a sealing action, making bolts and seals unnecessary.

ング剤２の一部が外へはみ出る程度に設定する。In addition, since the soft panel 3 has visibility, it can sufficiently cope with even slight irregularities on the surface of the structure violet, and the provision of the nonwoven fabric 4 on the inner surface provides strong adhesion with the lining agent 2. . The size and number of holes 5.5 in the soft panel 3 are set to such an extent that when the panel 3 is pressed against the lining agent 2, a portion of the lining agent 2 protrudes outside.

する必要がなくなってその手間とコストが軽減される。[Effect of the invention] As detailed above, according to the anti-corrosion construction method of claim (1), the soft panel is attached under pressure to the lining excavated soil applied to the structure, so the lining agent is repeatedly applied. There is no need to paint, which reduces the effort and cost.
また、軟質パネルは、不織布を介してライニング剤・上

ールも同時に行なわれる効果がある。In addition, since the soft panels are pasted onto the lining agent via the nonwoven fabric, they will not peel off, and the joints between each soft panel are filled with the lining agent, so there is an effect that sealing is performed at the same time.
更に請求項（２）の防食パネルを使用すれば、押圧力で
各孔内にライニング剤が侵入して硬化するので、パネル
とライニング剤の密着力が向上する効果がある。Furthermore, when the anticorrosive panel of claim (2) is used, the lining agent enters into each hole due to the pressing force and hardens, so that the adhesion between the panel and the lining agent is improved.
