In particular, the present invention relates to steel sheet piles with excellent anti-corrosion performance that are installed in the sea, rivers, etc., and methods for manufacturing the same.

な効果を有する鋼矢板の開発が待たれているのが
現状である。 Generally, steel sheet piles installed in the sea, rivers, etc. are most likely to be corroded in the so-called splash zone near the water surface, where both seawater or river water and air repeatedly come into contact without interruption. Therefore,
In order to protect the splash zone from corrosion, attempts have been made to cover it with concrete, apply anti-corrosion paint, or line it with rubber or FRP. However, these methods have problems such as insufficient adhesion to steel sheet piles and the need for a great deal of effort in construction, and the development of a simple and sufficiently effective steel sheet pile is awaited. The current situation is that

至つた。 As a result of various studies in view of the current situation, the present inventors have found that it is possible to effectively protect steel sheet piles from corrosion by bonding a fiber-reinforced thermosetting resin layer to the steel sheet piles via a metal sprayed layer. This discovery led to the present invention.
すなわち第１の発明は、鋼矢板の防食すべき面

化熱硬化性樹脂層を有することを特徴とする防食
鋼矢板を提供するものである。 That is, the first invention provides a corrosion-resistant steel sheet pile characterized by having a fiber-reinforced thermosetting resin layer integrally joined to the surface of the steel sheet pile to be corrosion-protected via a metal spray coating layer.

するものである。 In addition, the second invention forms a metal sprayed coating layer on the surface of the steel sheet pile to be protected against corrosion, and then supplies a thermosetting resin onto the sprayed coating and impregnates the inside of the sprayed coating at room temperature or under heating, At the same time as the impregnation or subsequently, a fiber-reinforced thermosetting resin composition layer is formed on the thermal spray coating, and then the thermosetting resin composition is cured to form a layer of the metal spray coating on the steel sheet pile to prevent corrosion. The present invention provides a method for manufacturing a corrosion-resistant steel sheet pile, which is characterized in that a fiber-reinforced thermosetting resin layer is joined using a method of manufacturing a corrosion-resistant steel sheet pile.

くない。 For example, the following method can be used to obtain the anticorrosive steel sheet pile of the present invention. First, if necessary, pre-treatment such as degreasing or blasting is applied to the surface to be protected against corrosion of the steel sheet pile, and then a thermal spray coating of approximately 10 to 500 microns is formed on the pre-treated surface by thermal spraying. . If the thermal spray coating layer is less than 10 microns thick, the fiber-reinforced thermosetting resin layer cannot be bonded with sufficient strength, and
Even if the thickness exceeds 500 microns, the increase in bonding strength corresponding to the increase in thickness is small, and both are undesirable.

ることができる。 The thermal spray coating is then impregnated with a thermosetting resin using conventional techniques such as hand lay-up, spray up, or filament winding, and the thermosetting resin and fibrous reinforcement are applied onto the thermal spray coating simultaneously or subsequently with the impregnation. A fiber-reinforced thermosetting resin composition layer is formed using the material, and then these thermosetting resins are cured to form a fiber-reinforced thermosetting resin composition layer on the surface of the steel sheet pile to be protected against corrosion via a metal sprayed coating layer. Corrosion-proof steel sheet piles can be obtained by integrating the resin layers.

ても良く、また打設した後に行なつてもよい。 The formation of the metal spray coating layer and the formation and curing of the fiber-reinforced thermosetting resin layer may be carried out before or after the steel sheet pile is cast.

る特許請求の範囲第４項記載の製造方法。[Scope of Claims] 1. A corrosion-resistant steel sheet pile characterized by having a fiber-reinforced thermosetting resin layer integrally bonded to the surface of the steel sheet pile to be protected from corrosion via a metal sprayed coating layer. 2. The anticorrosive steel sheet pile according to claim 1, wherein the metal spray coating layer has a thickness in the range of 10 to 500 microns. 3. The anticorrosive steel sheet pile according to claim 1, wherein the thermosetting resin is an unsaturated polyester resin. 4 Form a metal spray coating layer on the surface of the steel sheet pile to be protected against corrosion, then supply a thermosetting resin onto the spray coating and impregnate the interior of the spray coating at room temperature or under heating, simultaneously with or following the impregnation. , a fiber-reinforced thermosetting resin composition layer is formed on the thermal spray coating, and then the thermosetting resin composition is cured, and the fiber-reinforced thermosetting resin composition layer is applied to the surface of the steel sheet pile to be protected against corrosion via the metal spray coating layer. A method for manufacturing anti-corrosion steel sheet piles, characterized by joining hardenable resin layers. 5. The manufacturing method according to claim 4, wherein the metal sprayed layer has a thickness in the range of 10 to 500 microns. 6. The manufacturing method according to claim 4, wherein the thermosetting resin is an unsaturated polyester resin.
