  • Originally designed by:- The Dolos was designed in 1963 by a South African harbour draughtsman Aubrey Kruger, and were first used on the breakwater in East London, a South African port city. They work by dissipating, rather than blocking, the energy of waves. The Xblocks are based on Krugers design.

    • Kruger took inspiration from the configuration of spinal column bones. Legend has it that he was eating lunch at work, which consisted of ‘leftover’ oxtail stew. The design is ingenious in that the more the waves move the Dolos the tighter they interlock. He was originally working on a design to build a safe harbour for resettlement of the island of Tristan da Cunha after the devastating volcanic eruption that destroyed the original settlement on the island. He received no royalty for his design since he was working for the government harbours department. The design was not patented and was freely available for others to subsequently copy over the decades.

    • I am from NJ and they refurbished one of the main inlets with dolos back in the 1970s and they haven't moved an inch since then. I believe they used them prior to that on the US West coast.

    • The patent actually went to a French engineer in 1950... the Americans copied it in '59, the British copied it in '61, the Dutch in '62 and Kruger in '63... each one just shaped it to their own design.

    • Years ago in Ocean City,NJ, they made the jetty very tightly to nearly stop the water flow along the beach. This in turn created an edy effect that washed the beach away on the back side. Secret is to slow the wave action and not try to stop it completely .

  • Even better are systems that allow for marine habitat to form under the wave surface. Not only do these then allow for a more natural approach but marine ecosystems are created, and heck, recreational fishers can throw a line out for a catch!

    @dcentral@dcentral Жыл бұрын

    • Its more or less a yes and a no problem with rebar is that it degrades the concrete sooner

      @wolverines5279@wolverines5279 Жыл бұрын

    • Rebar is used in bridges, buildings, skyscrapers, homes, warehouses, and foundations to increase the strength of a concrete structure. Rebar is not necessary for every concrete project. It can corrode easily when exposed to water or air, and so significantly reduces the lifespan.

      @BariumCobaltNitrog3n@BariumCobaltNitrog3n Жыл бұрын

    • Concrete in isolation is good at resisting compressive forces. Rebar is used used in concrete to resist tension, bending moment and shear. These are forces experienced typically where concrete has to span a distance/opening. In this instance concrete is being used primarily for mass and is acting in compression. As others have written. In certain instances rebar reacts negatively to the atmosphere and corrodes and expands, which results in more damage than enhancement to the structure. This negative corrosive reaction would be massively multiplied in a salt water environment.

  • The design is pretty bad, the iron hook on top is just extra part to be attached, better is to use a mold shape that would form a spot where it could be lifted. When this iron rusts off, it becomes very difficult to lift.
