THE REASONS FOR JET GROUT METHOD'S SUCCESS
When compared to other soil development methods, jet grouting's long-term performance may appear fairly unexpected at first. However, when taking into account the distinctive results that can be produced by jet grouting, this fact is simply explained. They consist of the following:
1. By drilling a series of small holes into the earth with minimal damage to the surrounding subsoil, huge columns of cement can be produced.
2. Combining such columns to create continuous pieces of different sizes and forms that have excellent mechanical characteristics and very low permeability.
JET GROUTING SOLVES A LOT OF PROBLEMS
Jet grouting has provided innovative geotechnical solutions to practical problems in some specific circumstances (such as water sealing the bottom of open excavations in urban contexts), significantly enhancing the building process and transforming the design ethos.
The insertion of metal or fiberglass bars or tubes, which if necessary give an appropriate flexural and tensile resistance, can also be used to reinforce the jet-grouted parts. Thus, the majority of geotechnical issues can be resolved, such as enhancing the bearing capacity and minimizing foundation settlement, supporting both open-air and underground excavations, and constructing water cut-offs for hydraulic reservoirs or groundwater barriers for pollution management. Sketches of the commonest applications are created.
As a result, jet grouting has replaced more conventional geotechnical methods like piles in many geotechnical projects.
Jet grouting is appealing because soil treatment can be accomplished even in challenging operating circumstances and with relatively light equipment, working in small spaces or in locations that are challenging to access by other means. As a result, it can be used easily for protecting or improving existing facilities in addition to building new ones.
