Caisson revetment method

Abstract

Abstract Translated from Japanese (57)【要約】 （修正有） 【目的】 護岸とは別個に鋼矢板を打設する必要がな く、かつ、継手の数をできるだけ減少させた、換算透水 係数を小さくできる、しかも工期を短縮できるケーソン 護岸工法を提供する。 【構成】 製作したケーソン２を作業台船１に載置して 所定のケーソン設置位置まで曳航し、台船１と分離した ケーソン内に海水または中詰を投入して該ケーソン２を 沈下させてケーソンを設置するに際し、少なくともケー ソン設置位置にケーソン２を沈下させる前に、ケーソン ２の端部又は中央部に板状の止水板５を下方に突出する 如く取り付け、ケーソン２を沈下させると同時に前記止 水板５を基礎３中に圧入させ、順次同様にして沈下・圧 入したケーソン２相互及び止水板５相互を接続して護岸 を構築するケーソン護岸工法。 (57) [Summary] (Modified) [Purpose] It is not necessary to drive steel sheet piles separately from the seawall, the number of joints is reduced as much as possible, the reduced hydraulic conductivity can be reduced, and the construction period is shortened. Providing a caisson revetment method that can be done. [Constitution] The manufactured caisson 2 is placed on the work pontoon 1 and towed to a predetermined caisson installation position, and seawater or filling is poured into the caisson separated from the cradle 1 to sink the caisson 2. At the time of installing the caisson, at least before sinking the caisson 2 at the caisson installation position, attach a plate-shaped water stop plate 5 to the end or center of the caisson 2 so as to project downward, and at the same time allow the caisson 2 to sink. A caisson revetment method in which the water stop plates 5 are press-fitted into the foundation 3, and the submerged / press-fitted caisson 2 and water stop plate 5 are connected in the same manner to construct a seawall.
