Understanding the working mechanism of jet grouting



Jet grouting is a process in which diversified materials including soil, water, lime etc are mixed together to improvise the texture and elasticity of the soil. Meanwhile, jetting equipments are used and it can dig holes up to 150 mm. Extreme high pressures is used of grout to wear away, replace, mix, and cement soils. In the jet grout construction process, a rotating drill rod is used with a small nozzle and it can dig the surface of the earth because of the application of high intensity in the pressure. The distinctive column diameters vary from 2 to 6 feet. Regardless of the soil texture, any type of soil can be grouted with the help of jet grouting. If the soil is not grouted well and the ground improvement is not done, then it will surely leave long term negative effects and the building will always be prone to hazard.
 
There are three types of jet grouting varying on the requirement of the project. In some projects, air jet grouting is required, whereas in some of the projects water jet is the requirement. So depending on the requirement of a particular project, jet grouting is carried on.  Subsequently, a bulky and powerful pump is attached to the jet drill rod, which pumps the lofty heaviness jet grout throughout the drill rods vertically and horizontally deep into the soil. After the fixture of the machine, the drill rods are rotated in a smooth manner and raised for creating columns of soil-cement. The silhouette of the grouted zone can be transformed by directing the grout in different manner that further create panels, floors, and any other shape.

Jet grouting can construct soilcrete in cramped surface of the soil and subsurface the various obstructions like utilities, provides a unique degree of design suppleness. So from now, make sure that jet grouting is done for ground improvement and then the further construction procedure should be carried on.
