The present invention discloses a pile foundation permeable breakwater with variable permeability, comprising: two rows of prefabricated pile foundations. The tops of the prefabricated pile foundations are fixedly provided with a prefabricated panel. The top of the prefabricated panel is provided with a wave wall and a breast wall. The prefabricated pile foundations are integrally connected with fixed wave breaking plates; sliding rails are installed correspondingly on the top and the bottom between every two adjacent prefabricated pile foundations in the same row; and movable wave breaking plates are slidably connected between each pair of sliding rails. A control system for controlling the slide of the movable wave breaking plates is installed on the prefabricated panel. The present invention also discloses a construction method of the pile foundation permeable breakwater with variable permeability.

A weight distribution and stiffening system is provided for modular floating platforms by creating internal channels that allow for the incorporation of stiffening members within the modular floating platform assembly. Float modules with horizontal recessed areas that are aligned with adjacent float modules to create open channels within the body of a modular floating platform.

A load distributing and absorbing system that lies below a barrier layer that is exposed to percussive and/or point-applied forces. The load distributing and absorbing system has one or more load distributing and absorbing tiles. At least some of the tiles have an underlayment infrastructure positioned below a barrier layer. The underlayment infrastructure includes one or more hat-shaped absorbing members. Each has a ceiling primarily for load distribution and a curvilinear wall primarily for load absorption extending from the ceiling. A transition feature is provided to smoothly graduate from one height and type of load distributing and absorbing tile to a load distributing and absorbing tile of another type and height. He system distributes and absorbs forces applied to the barrier layer over a broad area when applied either on a seam between adjacent tiles or within a tile.

The present invention relates to a removable artificial reef and barrier system capable of mitigating detrimental wave and current energy and erosion problems, enhancing biological growth and marine aquaculture, increasing carbon sequestration, providing power generation, and enhancing favorable surf conditions for recreational use.

Disclosed is a triangular modular ecological seawall, including a plurality of first prefabricated frames arranged in an array, a second prefabricated frame and a wave break forest which are disposed between two adjacent first prefabricated frames and fill gaps between the first prefabricated frames, the first prefabricated frame and the second prefabricated frame are tubular and each have a triangular cross-section shape, and inner cavities of the first prefabricated frame and the second prefabricated frame are respectively filled with first sea sand.

A universal framing system for a boat dock generally includes at least one standardized dock frame. The standardized dock frame is in a rectangular shape. Each of the standardized dock frames include a standardized left side member, a standardized right side member, a standardized front end member, and a standardized back end member. The standardized left side member may be on a left side of the rectangular shape. The standardized right side member is on a right side of the rectangular shape. The standardized front end member is on a front end of the rectangular shape. The standardized back end member is on a back end of the rectangular shape. The standardized left side member, the standardized right side member, the standardized front end member, and the standardized back end member are configured to connect together to create the rectangular shape.

A system for impeding shore erosion includes a sea-facing barrier wall penetrated by large holes that allow water with entrained sand to enter the apparatus. Smaller holes provided in a rear wall allow the water to drain into an underlying reservoir after the entrained sand has settled. An extension can be abutted to a top of the barrier wall to enhance sand collection during a storm. Water that flows over the barrier wall is caused to flow over a top of the extension, whereby water with entrained sand falls through openings in the extension top. Sand collected by the extension remains on the shore when the extension is removed. The apparatus can include plywood, metal, or plastic. Embodiments can be disassembled and/or folded for transport and storage. Internal reinforcing partition walls can extend between the barrier and rear walls. The apparatus can be further anchored by stakes.
