How is concrete distributed using a concrete mixer and a concrete pump????? Leave a like if you liked the video! -------------------------------------------------------------- Today, Moritz is all about construction machinery. At a construction site, Moritz sees lots of big machines, including a concrete mixer. Site manager Jannis takes Moritz to the construction site where a high-rise building is being built. He explains to him how the construction site works. There is a large excavation pit where lots of construction workers are working; cranes are used to transport things like iron bars and a portable toilet back and forth. The concrete mixer brings liquid concrete, which is drained into a concrete pump via a chute. The concrete mixer holds eight cubic metres of concrete. That's about as much as fits into a garden pool. The concrete is poured from the concrete pump into the ceiling via a long pipe with a flexible hose. The construction workers use the hose to distribute the concrete evenly over the surface. They stand on grid mats into which the concrete flows. A construction worker, Volodymir, controls the concrete pump with a remote control. The air is shaken out of the concrete using the vibrator bottle. The concrete is then distributed evenly and evenly over the surface. When the concrete mixer is empty, a signal is given and everyone knows that no more concrete will come out of the pump soon. The empty concrete mixer drives off the construction site and Volodymir cleans the concrete pump and puts a sponge-like ball into the pump pipe from below. Moritz is allowed to help dismantle the concrete pump. To do this, he straps the remote control around his stomach and Volodymir shows him how to slowly fold the long mast. The mast consists of several parts. Like a long arm with different joints. Construction worker Michael checks the freshly distributed concrete. To do this, he gets a bucket of concrete and together they go to the concrete laboratory, where they carry out various tests. Moritz shovels concrete into a kind of funnel to test how solid the concrete is. The funnel is lifted off and the concrete is spread over the surface, which is lifted and dropped a total of 15 times. Moritz measures how wide the concrete slab is. The concrete is then shoveled into a cube-like shape. The concrete is compacted using a vibrating plate and then weighed on the scales and the temperature measured. The sample cubes are frozen. Moritz goes back to the construction site, where the concrete is smoothed with a power trowel. ???? More about the elephant in the ARD media library: https://www.ardmediathek.de/elefant ????
