。Joints for steel pipe sheet piles are often not strength members, so in such cases it is sufficient to anticipate corrosion, but if the joints are also strength members or have a long service life, corrosion prevention measures should be taken on-site after installation. It is necessary to apply However, there is currently no method that can be implemented economically and easily. Before driving the steel pipe sheet piles, it is possible to install one with anti-corrosion measures applied to the ends, but since the anti-corrosion film will peel off during the installation process, it is recommended to install without anti-corrosion treatment. It is customary.
この発明は前記従来の問題点を解消すべく開発したもの
で、以下その詳細を図示した***例によって説明する
。This invention was developed to solve the above-mentioned conventional problems, and the details thereof will be explained below with reference to illustrated examples.
鋼管矢板の本体1には逼轟な形状の継手2が設けてあシ

らなる溢枠3がIIIIi!シて央設されている。The main body 1 of the steel pipe sheet pile is provided with a joint 2 of a resonant shape, and overflow frames 3 made of flat steel are provided at a required interval in a direction substantially parallel to the joint 2! It is centrally located.

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
しである。ところでペトロラタム含浸袋4は合成繊維、

含浸させたものである。The above steel pipe sheet piles are connected by Kempo joints 2 and driven to a predetermined depth, and the machine frame 5 placed in the center of the steel pipe sheet piles is placed in front of the engaged joints 2 with their tips overlapping each other at the required interval. , - After suitably removing the earth and sand between the hand 2 and the formwork 5, a petrolatum-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 to the joint 2. It is. By the way, the petrolatum-impregnated bag 4 is made of synthetic fiber.
This is a bag made of cotton cloth or the like impregnated with synthetic Compadnovetrolatum haest.
充填材料5としてはセメントモルタル、コンクリート等

合でよい。The filling material 5 may be cement mortar, concrete, etc., and an expanding agent must be added thereto. Also, a poor blend of cement (cemen) fl may be used.
ペトロラタム社防錆剤としてきわめて秀れたものである
。しかし鋼材には密着するものの付層力は殆んど期待で
きないので充填材料5によって袋4を絶えず一定圧力を
かけて継手2に圧着しうる充填材料5を使用する。Petrolatum is an excellent rust preventive agent. However, although it adheres closely to the steel material, almost no adhesion force can be expected, so a filling material 5 is used that can press the bag 4 to the joint 2 by constantly applying a constant pressure to the bag 4.

かつ保躾し、完全な防蝕をすることができる。The present invention has the above-mentioned structure, and the joint part can be rust-proofed by impregnating a bag with petrolatum and pressing it onto the joint part using a light horizontal material filled in the bag. Further, by using a bag, it is possible to adapt to the complicated shape of the joint part and perform crimping. In addition, since petrolatum has no adhesive properties, it is easy to insert it into the space between the joint and the formwork, and it also allows the positioning and maintenance of the formwork bag to be regulated and maintained, providing complete corrosion protection.
