【発明の詳細な説明】
この発明は設置した鋼管矢板継手部の防蝕装置に関する
ものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a corrosion protection device for installed steel pipe sheet pile joints.
鋼管矢板の継手は強度部材でない場合が多いので、かか
る場合は腐蝕代を見込むのみで十分であるが、継手も強
度部材である場合あるいは耐用年数が永い場合には打設
後に現地で防蝕措置を施す必要がある。Joints of steel pipe sheet piles are often not strong members, so in such cases it is sufficient to allow for corrosion, but if the joints are also strong members or have a long service life, it is necessary to take on-site corrosion prevention measures after installation. It is necessary to apply
しかしながら従来経済的かつ簡便に実施しうる方法がな

通例である。この発明は前記従来の問題点を解消すべ〈
開発したもので、以下その詳細を図示した実施例によっ
て説明する。However, there is currently no method that can be implemented economically and easily. Before driving the steel pipe sheet piles, it may be possible to install corrosion-resistant coatings on the joints, but since the corrosion-resistant film will peel off during installation, it is customary to install the joints without applying any anti-corrosion measures. It is. This invention should solve the above-mentioned conventional problems.
The details will be explained below with reference to illustrated embodiments.
鋼管矢板の本体１には適当な形状の継手２が設けてあり

空所にべトロラタム含浸袋４を挿入しかつその袋４内に
充填材料５を充填して継手２に袋４を圧着してある。The main body 1 of the steel pipe sheet pile is provided with a joint 2 of an appropriate shape, and formwork 3 made of flat steel is welded and protrudingly provided at a required interval in a direction substantially parallel to the joint 2. The above-mentioned steel pipe sheet piles are sequentially connected with joints 2 and driven to a predetermined depth, and the formwork 3 protruding from the steel pipe sheet piles is overlapped at the tip and positioned at the required interval in front of the joined joint 2. After suitably removing earth and sand between the mold 2 and the formwork 3, a betarolatum-impregnated bag 4 is inserted into the empty space, and the bag 4 is filled with the filling material 5, and the bag 4 is crimped onto the joint 2. be.
ところでべトロラタム含浸袋４は合成繊維、綿布等の袋
に合成コンパッドのべトロラタムベーストを含浸させた

ンクリート等であり必要に膨張剤を配合する。By the way, the Betrolatum-impregnated bag 4 is a bag made of synthetic fiber, cotton cloth, etc., impregnated with Betrolatum base, which is a synthetic compound. The filling material 5 is cement mortar, concrete, etc., and an expanding agent is added if necessary.
またセメントは貧配合でよい。べトロラタムは防錆剤と
してきわめて秀れたものである。Also, the cement may have a poor blend. Betrolatum is an excellent rust preventive.
しかし鋼材には密着するものの付着力は殆んど期待でき

圧着させておくことにより継手部を防錆することができ
る。However, although it adheres closely to the steel material, almost no adhesion force can be expected, so a filling material 5 is used which can adhere to the joint 2 by constantly applying constant pressure to the bag 4 using a filling material kite. The present invention has the above-mentioned basic structure, and the joint can be rust-proofed by impregnating a bag with betarolatum and pressing the bag against the joint with the filling material filled in the bag.
また袋を使用することにより継手部の複雑な形状に順応
して圧着することができる。またべトロラタムは付着性
がないので継手部と型枠との空所に挿入する作業が容易

全な防蝕をすることができる。Further, by using a bag, it is possible to adapt to the complicated shape of the joint part and perform crimping. In addition, Betrolatum is non-adhesive, so it can be easily inserted into the space between the joint and the mold, and the mold can regulate and protect the bag, providing complete corrosion protection.
