装することができるようになる。Particularly in accordance with the invention, the nozzle 6 is in a fixed position with a predetermined angle θ1 at which the axis of the nozzle 6 is oblique with respect to the downstream side (right side in FIG. 1) of the moving direction 9. Since it is moved in the moving direction 9 along the surface to be coated 2, the thickness d1 (see FIG. 1) of the coating film 3 can be set to a desired value by changing the angle θ1, for example. . This makes it possible to evenly coat the surface 2 to be coated, which is an uneven surface of a structure such as a steel sheet pile, with a desired film thickness.

に得ることができる。Further in accordance with the present invention, the coating material 7 from the tip portion 8 of the nozzle 6 first adheres to the surface of the sheet material on the surface 2 to be coated,
Next, the sheet material 4 is pressed against the surface 2 to be coated using the roller 13 to form the coating film 3 having a uniform thickness of the coating material 7a attached to the sheet material 4, and thus the sheet material 4 is formed. By pressing 4 after applying the paint 7 to it, a uniform film thickness can be obtained with respect to the corner portion of the surface 2 to be coated at the fixed position. Generally, in the corner portion, the film thickness tends to decrease to about 50 to 80% of the desired value other than the corner portion due to the fluidity of the coating material. 7
Since the sheet material 4 to which the paint 7 is attached is pressed against the surface 2 to be coated by the roller 13 and the paint is constantly supplied from the nozzle 6, the film is formed even in such a corner portion. It is possible to obtain the same thickness as the portion other than the corner portion.

The coated surface 2 extends above and below the water surface boundary portion 5,
In this area, as described above, the coating film 3 is formed and the sheet material 4 is provided. In the steel sheet pile 1, the submerged portion below the water surface boundary portion 5 can be subjected to electrocorrosion, but the water surface boundary portion 5 is vertically displaced and is above the water surface boundary portion 5 to which the droplets adhere. Therefore, corrosion is particularly likely to occur in the vicinity of the water surface boundary portion 5, and the surface 2 to be coated includes such a region.

ことが防がれる。A spatula 10 is provided integrally with the nozzle 6 near the tip portion 8 of the nozzle 6, on the upper portion of the tip portion 8, that is, on the upstream side in the moving direction 9 (left side in FIG. 1). The spatula 10 applies the paint 7 fed from the nozzle 6 to the surface 2 to be coated.
Push it to the side. As a result, the thickness d1 of the coating film 3 is made uniform to a desired value. At the tip 8 of the nozzle 6,
On the downstream side (right side in FIG. 1) of the moving direction 9 of the tip portion 8, a plate-like sealing plate 11 having elasticity such as rubber is fixed. The seal plate 11 prevents water, air, and the like from entering and interposing between the surface 2 to be coated and the coating film 3.

The coating film 3 is covered with the sheet material 4 while being adhered to. The sheet material 4 is made of, for example, a synthetic resin such as vinyl, has flexibility, is denser than the coating film 3, and functions to prevent diffusion of moisture and oxygen from the outside into the coating film 3. Fulfill The sheet material 4 may be a material that remains adhered to the coating 3, or the cured coating 3
It may also be made of a material having a property of peeling from. The surface of the sheet material 4 opposite to the surface 2 to be coated is pressed by the roller 13 toward the surface 2 to be coated on the upstream side of the spatula 10 in the moving direction 9 and adheres to the coating film 3. The sheet material 4 is guided to the roller 13 side by the roller 14. The rotation axes of the rollers 13 and 14 are parallel to the surface 2 to be coated and perpendicular to the moving direction 9. The nozzle 6 and the rollers 13 and 14 move integrally in the moving direction 9.

保たれるときには、塗膜３の厚みd1が薄くても済む。Therefore, even when water is in contact with the surface 2 to be coated, the coating film 3 is formed on the surface 2 to be coated, and the sheet material 4 is attached thereon. The sheet material 4 prevents waves from directly colliding with the coating film 3, and thereby prevents damage to the coating film 3 due to waves. Further, the sheet material 4 acts as a resistance for water and oxygen to diffuse into the coating film 3, thus preventing the steel sheet pile 1 from rusting. When the sheet material 4 is kept attached to the coating film 3 even after the coating film 3 is cured, the thickness d1 of the coating film 3 may be small.

A tip 8 of a nozzle 6 is arranged in the vicinity of a surface 2 to be coated which is fixed in water and / or in the vicinity thereof, and the nozzle 6 is moved in a moving direction 9 along the surface 2 to be coated. The axis of the nozzle 6 moves at a predetermined angle θ1 with respect to the downstream side in the moving direction 9 and moves, and the underwater curable coating material is pressure-fed and supplied from the tip portion 8 of the nozzle 6 to be coated. A coating film 3 is formed on the surface 2, and a plate-like seal plate 11 having elasticity is fixed on the surface 2 to be coated of the tip portion 8 of the nozzle 6, whereby water and air are applied to the surface 2 to be coated. The spatula 10 is integrally provided on the tip 8 of the nozzle 6 to prevent it from intervening by interposing with the membrane 3.
The paint 7 is pressed against the surface 2 to be coated, and is flexible and is externally applied by the roller 13 having a rotation axis perpendicular to the moving direction 9 on the upstream side of the spatula 10 in the moving direction 9. The surface of the sheet material 4 on the side opposite to the coated surface 2 for preventing the diffusion of moisture and oxygen into the inside is pressed against the coating film 3 to be in close contact, and the thickness of the coating film 3 is made uniform. A coating method in which the nozzle 6 and the nozzle 6 move integrally in a moving direction 9.
