Marvelous Technological Wonder Of Shotcrete Equipment To Construction

Along with the progression of the world, the ways of the construction industry is fast evolving as well. People are finding new ways to simplify their work in building complex structures. One of the most useful invention that has made been recently is shotcrete equipment.

Shotcrete is mortar conveyed through a hose and projected into the surface, known as a construction technique. It can be impacted into any type of surface, be it vertical or overhead. It is used to be called as cement gun for the capability it possesses. It is vital on the work of miners and tunnel engineers because it can make the tunnel wall stronger.

For starters, if you think this has been recently discovered it is not. It is actually a century old technique that brought us back in early 1900s wherein it was accidentally discovered by a American taxidermist named Carl Akeley. History says he use a technique where a device blow a dry plaster out of a hose with a compressed to the skin of an animal that he wants to preserve.

Later in 1911, the technique was registered under his name and got the first official name of cement gun. However, it was in 1950s that it makes a breakthrough to the world when a Austrian tunnel engineer discovered it has the potential to effectively reinforce tunnel walls and avoid any cave ins. It was at that time that the technique receives worldwide recognition and application named as new Austrian tunneling method.

Recently, it is used commonly for providing underground support in projects or industries such as mining and tunnel excavation and construction. It has also become a widely used application in the mining industry in providing underground support to permanent opening such as ramps, shaft stations, and crusher chambers. People mistakenly call this method as gunite which actually refers to the dry process.

The technique is divided into two that is the wet and dry mixes. The dry mix method involves placing the dry ingredients into a hopper and then conveying them through a hose to the nozzle. The liquid and the dry mixture is not mixed completely, but is completed as the mixture hits the surface. Advantage of the dry mix process is that the water content can be adjusted instantly allowing more effective placement without using any accelerators.

Furthermore, wet mix type involves premixing the materials with water. It is then delivered on a concrete pump to be sprayed on any surface with an aid of a compressed air passing through a nozzle. This is perfect for mining projects that require making deep shafts and long tunnels.

As we are facing an era of technological wonder this method has a truly advanced counterpart named as Robotic Shotcreting Machine. It has the capability of spreading the compact and mixture at the same time. The best part of it is that it does not require a skilled operator because it so easy to handle.

This technology is just one of the many engineering marvels in our generation. It has some humble beginnings in the hands of a taxidermist and now shotcrete equipment is saving lives and creating beautiful structures. The future of its advancement is full of endless possibilities.
