    • PROBLEM TO BE SOLVED: To eliminate the influence of an uplift pressure due to a tide level difference of a construction water area as much as possible when closing an opening of an impervious type revetment by an inclined dike comprising natural stones or the like.SOLUTION: On a top end face of a foundation mound 26, a first top end height H1, with which securing the water conduction cross section Ws between outside and inside of a dike at lower position than a water level at the high tide is possible, is set taking the tide level difference of the construction water area into consideration, and a first impervious structure 24 extending from the first top end height H1 to an intra-dike bottom surface part is created. While making it possible to exchange water between outside and inside of the dike through the water conduction cross section Ws, the influence of the uplift pressure passing through the foundation mound 26 from the outside of the dike and acting on the back surface of the first impervious structure 24 is suppressed as much as possible. In the following process of creating a second impervious structure extending from a second top end height H2 at a position higher than the water level at the high tide in the construction water area to the intra-dike bottom surface part, the influence of the uplift pressure from the outside of the dike is eliminated by the first impervious structure 24.

    • 【課題】トレミー管を用いた土砂投入工において、周辺水域の濁りの発生を、より効果的に抑える。【解決手段】トレミー管10により土砂20の落下経路が画定され、トレミー管10の頭頂部に設けたホッパー14から投入される土砂20が、水中に飛散して濁りを発生することなく、トレミー管10の下端部16から水底面へと放出される。下端部16から所定高さHまでの範囲が、外力を受けて自在に変形する変形可能部22として構成され、トレミー管10が作業船12の揺れにつられて揺動し、トレミー管10の下端部16が水底面に衝突しても、トレミー管10の下端部16を構成する変形可能部22が自在に変形して、破損を防ぐ。よって、変形可能部22の下端を、土砂を投入する水底面GLに対し、可能な限り接近させて、土砂20を投入することが可能となる。【選択図】図1
    • 要解决的问题:更有效地抑制使用颤音管道在地球工作中周围水域中的浊度的发生。解决方案:砂土20的落下路径由颤音管10限定,并将土砂20倾倒 从设置在颤音管10的顶部的料斗14排出到颤音管10的下端部16到水底,而不会由于在水中的飞散而发生浑浊。 从下端16到预定高度H的范围被构成为通过接受外力而自由变形的可变形部22。 即使当颤抖管10滚动时,工作船12的滚动和颤音管10的下端16与水底相撞,则构成颤音管10的下端16的可变形部22自由变形并防止 破损。 因此,能够将可变形部22的下端尽可能靠近水底GL倾倒土砂,并能够将土砂20倾倒。

    • PROBLEM TO BE SOLVED: To provide a cutting device that can form an opening for removing an infilling material by cutting an upper cover of a caisson at low cost even when the upper cover is thick.SOLUTION: A cutting device 1 includes: a core drill which forms through holes 6 to be used as a throw-in hole 6a and a recovery hole 6b in an upper cover 4; a floating body 8 which is connected to a lead wire 7 for guiding a wire used in wire sawing and thrown in through the throw-in hole 6a of the upper cover 4 to be arranged on a water surface below the upper cover 4; and a suction pipe 12 which moves the floating body 8 from the water surface below the throw-in hole 6a to a water surface below the recovery hole 6b with suction hydrodynamic force 15 so as to recover the floating body 8 to the outside. Consequently, the wire for wire sawing can be wound between the throw-in hole 6a and the recovery hole 6b of the upper cover 4, so that an opening 5 for removing an infilling material 3 can be formed in the upper cover 4 at low cost.

    • PROBLEM TO BE SOLVED: To provide a seawater exchanging device capable of exchanging seawater in the vertical direction efficiently without being affected by the depth of seawater and a tidal current and having a wide scope of application.
      SOLUTION: A tubular structural body 12 having a water passage 11 in its inside is provided on a face of slope in a form for replacing with one row of covered blocks, and a lower end opening 13 and an upper end opening 14 of the tubular structural body 12 are positioned in a section just above the ground 1 on the sea bottom and in the vicinity of average tide level, respectively. Difference occurs in water pressure acting on both end openings due to difference in phase of waves at positions corresponding to both end openings 13, 14 of the tubular structural body 12, and downward flow or upward flow is induced in the tubular structural body due to the difference in water pressure.
