    • Buoyant wharf modules of a floating dock include a rotary molded polyethylene structure having a lower shell portion filled with a steamed polystyrene foam and an upper portion that is a permanent mold form for a concrete aggregate-water mixture. The foam has sufficient compressive strength so that when the mixture is poured into the form over a reinforcing mesh, the form remains stable. The form includes troughs and mesas shaped so that the water flows by gravity to sumps adjacent walls of the form. The walls have openings so the water can flow from modules. Lined tunnels in the set concrete include removable rods having threaded ends which extend through openings in wales extending along longitudinal walls of the modules. Nuts and washers threaded on the rods abut exterior side walls of the wales to hold the modules together. Short spacer tubes having straight side walls abut wales of side-by-side modules. Rods of the side-by-side modules extending through openings of the tubes and walls connect the side-by-side modules to each other by a thread, nut and washer arrangement. Utility lines extending through the tubes extend to a utility tower on an outboard edge of one of the modules via a transverse opening in that module and a depression on that module under the tower. Notches in a bottom face of the modules enable forklift trucks to move the modules on land.
    • 浮动码头的漂浮码头模块包括具有填充有蒸汽聚苯乙烯泡沫的下壳体部分和作为混凝土骨料 - 水混合物的永久模具形式的上部部分的旋转模制聚乙烯结构。 泡沫具有足够的抗压强度,使得当混合物在增强网上注入形式时,该形式保持稳定。 该形式包括槽和台面形状,使得水通过重力流动到与形式的相邻壁相连。 墙壁有开口,所以水可以从模块流出。 集合混凝土中的衬里隧道包括具有螺纹端部的可移除杆,其延伸穿过沿着模块的纵向壁延伸的纵行的开口。 在杆上螺纹连接的螺母和垫圈邻接在纵行的外侧壁上以将模块固定在一起。 具有直的侧壁的短间隔管邻接并排模块的纵行。 通过管和壁的开口延伸的并排模块的杆通过螺纹,螺母和垫圈装置将并排模块彼此连接。 延伸穿过管道的公用设施线路通过该模块中的横向开口延伸到其中一个模块的外侧边缘上的公用事业塔,以及在塔下方的该模块上的凹陷。 模块底面的凹槽使叉车能够在陆地上移动模块。
