Technology is making some breakthroughs in the construction industry. We are making more complex structures and it is taking lesser time to complete them with the many techniques employed. One of those known methods that has contributed marvelous things to the world of construction is the shotcrete equipment.
Shotcrete is a construction technique wherein a concrete passing through a hose is projected in a high velocity into a surface. This was once called cement gun because of its ability to spray cement on the wall. It is an extremely useful technique for building tunnels which save the lives of many miners because it strengthens the wall of any tunnel.
Surprisingly, this is a century old method that was first used by a taxidermist from America. Carl Akeley invented a device he used to spray dry plaster on a dead carcass on animal to preserve it. He discovers it because he was dissatisfied with the unrealistic forms over which animal hides was preserved.
Back in 1911, the invention of what became known as the cement gun was patented by Akeley and developed further by the Allentown Cement Gun Company. Forty years after, a Austrian tunnel engineer realized that concrete sprayed invention could effectively reinforce tunnel walls, providing protection against collapse. This tunneling technique, now has been known as the new Austrian tunneling method, has become widely used around the world.
In modern times, it provides support for underground projects such as mines and tunnels and some any constructions as well. It is important for the ramps, shaft stations, and crusher chambers because it provides support and make their openings sturdy. Many people mistakenly call it gunite because they got used to the term.
There are two known types of this method which is dry mix and wet mix. Dry mix type involves the dry materials placed into a hopper and sometimes dampen with a little water to reduce the dust when sprayed. The material is then placed on a rotating barrel and with a help of compressed air it is sprayed to any surface through a delivery hose. Gunite is popularly attached to this dry process.
Whereas, the wet mix is thoroughly mixed with liquid. It is then placed on a concrete pump to be sprayed using a nozzle with an aid of a compressed air. This is better suited for high productions of mining and civil engineering project where deep shaft and long tunnel is being driven and where delivery trucks have ample space to operate.
Technological advances has a way of turning conventional technologies to completely convenient machinery. Shotcrete is not exempted to this progress because a newly developed Robotic Shotcreting Machine is widely used in any construction now. It has many advanced features introduced that makes the work a breeze.
Such an incredible work of marvel started out from the palm of a taxidermist and now it is vital on all constructions. Shotcrete equipment has indeed come a long way and it has no plans in slowing down. The future of this technology is full of promise.
