この発明は、直線型鋼矢板、Ｕ型鋼矢板、Ｚ型
鋼矢板あるいは鋼管矢板等の鋼製矢板を使用した
鋼製矢板構造物の防食方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for preventing corrosion of steel sheet pile structures using steel sheet piles such as straight steel sheet piles, U-shaped steel sheet piles, Z-shaped steel sheet piles, or steel pipe sheet piles.
鋼製矢板を使用した港湾構物あるいは人工島に
おける潮の干満帯および飛沫帯は、最も腐食量が
大きい部分であり、この部分の防食は必要不可欠
である。 The tidal zone and splash zone of harbor structures or artificial islands that use steel sheet piles are the areas that experience the greatest amount of corrosion, and corrosion protection in these areas is essential.
従来、鋼管杭を使用した港湾構造物あるいは海
洋構造物における干満帯および飛沫帯の防食方法
としては、腐食しろによる方法、塗装による方
法、あるいは鋼管杭自体の形状が筒状であること
から杭をFRP等のカバーにより被覆し、そのカ
バーと杭との間にモルタルを充填する方法などが
用いられている。 Conventionally, methods for preventing corrosion in tidal zones and splash zones in port structures or offshore structures using steel pipe piles include methods using corrosion margins, methods by painting, or because the shape of the steel pipe pile itself is cylindrical. The method used is to cover the pile with a cover such as FRP and fill the space between the cover and the pile with mortar.
一方、鋼製矢板の場合は、その形状が複雑であ
るので、従来用いられてきた防食方法としては、
腐食しろによる方法、塗装による方法あるいは型
枠を組立ててコンクリートを打設することによ
り、鋼矢板にコンクリートコーテイングを施す方
法等がある。 On the other hand, in the case of steel sheet piles, their shape is complex, so the conventional corrosion prevention methods used are:
There are methods to apply concrete coating to steel sheet piles, such as by using corrosion allowance, by painting, or by assembling formwork and pouring concrete.
しかしながら、腐食しろによる方法の場合は、
抜本的な対策と云うことができず、しかも錆によ
る外観不良の問題がある。また塗装による方法の
場合は、現場塗装が困難であるため工場塗装にな
らざるを得ず、かつ矢板打込時に導枠との摩擦に
より塗装が剥離したり耐久性に乏しい等の欠点が
ある。さらにまたコンクリートコーテイング法の
場合は、干潮面の下方から飛沫帯の範囲まで型枠
を仮設する必要があるので、型枠の仮設および撤
去のため作業架台製作に多くの手間を要し、かつ
水中作業が多い等の施工上の欠点がある。 However, in the case of the corrosion margin method,
This cannot be called a drastic countermeasure, and there is also the problem of poor appearance due to rust. Furthermore, in the case of the painting method, it is difficult to paint on site, so painting must be done at a factory, and there are drawbacks such as peeling of the paint due to friction with the guide frame during sheet pile driving and poor durability. Furthermore, in the case of the concrete coating method, it is necessary to temporarily set up formwork from below the low tide level to the range of the splash zone, so it takes a lot of time and effort to create a work platform for temporary setting and removal of the formwork, and There are construction disadvantages such as a lot of work.
一般に港湾構造物の耐用年数は、長期のものが
殆んどであり、一度築造されると維持管理が容易
でないものが多く、したがつて長期間にわたつて
防食を必要とするものにはコンクリートコーテイ
ング法が最適であると考えられる。 In general, most port structures have a long service life, and once constructed, maintenance is not easy in many cases.Concrete is therefore used for structures that require corrosion protection over a long period of time. The coating method is considered optimal.
この発明は、前記各防食方法の欠点を排除した
鋼製矢板構造物の防食方法を提供することを目的
とするものである。 The object of the present invention is to provide a method for preventing corrosion of steel sheet pile structures, which eliminates the drawbacks of the above-mentioned corrosion protection methods.
