![]() (Side note: you could say that a company is "knocking down an old building" but it wouldn't have the same effect as saying "they're demolishing the old building"). "I accidentally pushed my shopping cart into a display stand, and all the apples fell down." "They're demolishing the empty building so they can build a school there." "I heard they're demolishing the old hotel on 1st street." I would say to just use "demolish" when you are talking about destroying buildings/structures, and "knock down" for hitting objects off a surface (or to the side like "I accidentally knocked my glass of water over"). If your neighbour asked you what you were doing, you could say "I'm knocking down the old fence so I can replace it" (although you could also say "I'm taking down the old fence"). Let's say for example, you are replacing the wooden fence in your backyard because you plan on putting new ones up. The resulting bagged and labelled material is sent directly to concrete pre-cast stations nearby to produce new building blocks.It's a little tricky to explain because "knocked down" can also be used even if you intentionally did something. Meanwhile, the water is recycled by a centrifugal decanter to separate it from the solids and the stripped concrete is separated into aggregate and cement and bagged by ERO, while turbulence dynamos reclaim part of the energy used in the process. The more or less intact steel can be easily cut up for reuse or sent off for scrap. What’s left is clean rebar that even has the rust stripped off. EROS uses high-pressure water jets to hammer into the cracks in the concrete, pulverizing it and stripping it away by means of a vacuum system. This is a technique currently used for repairing reinforced concrete structures. They would do this by means of hydro demolition. The robots would scan the site, plan out their own routes, and then fan out to erase the building. According to Haciomeroglu, this allows ERO to dispense with hydraulic stabilizers and simplifies design. These are cylindrical treads that propel the robot forward and back like a caterpillar tractor or rotate on their axis to make the robot crab sideways. The robots would move about on omni-directional tracks developed by Osaka University. If space permits, explosives are fitted into the building’s left columns, making it fall to the side when detonated. Buildings are imploded in one of two ways. In operations, a fleet of EROs would be be deployed at a demolition site. Implosion is the process of using explosives to knock out a building’s main supports, causing the building to collapse from the inside out. It demolishes buildings by eating or “erasing” them section by section and layer by layer with an articulated arm equipped with a water-jet/vacuum head. At the end, the waste material still needs to be transported out of town for disposal or to recycling at depots where the concrete and the last of the rebar need to be separated and the concrete crushed for reuse.ĮRO is a winning concept design in the Student Designs category of the 2013 International Design Excellence Award and replaces several machines with a single autonomous robot type. ![]() There’s also a great deal of water involved because fire hoses are needed to continually douse the area to suppress dust. The end result is a process that requires huge amounts of power, lengthy separation of crushed concrete and twisted rebar, and the machinery and transportation to achieve this. This brute force method is even used by advanced demolition robots that rely on jack hammers and shovels. This provides a great deal of strength, but it also makes demolition a slow, difficult process involving a great deal of smashing, bashing, and crushing. Reinforced concrete consists of concrete poured on a mesh of steel rebar. But what about a robot that eats buildings? Omer Haciomeroglu of Sweden’s Umeå Institute of Design has come up with the concept ERO concrete de-construction robot, which uses high-pressure water jets to strip concrete from rebar and recycle it on the spot. We knock them down, blow them to bits, and build machines to take them apart. ![]() When it comes to demolishing buildings, there are almost as many ways to take them apart as put them up.
