Jet-grouting technology based on using of high-pressure mud jet energy for simultaneous soil destruction and mixing.
After hardening of the mortar, a new material is formed - ground concrete, which has high strength and deformation characteristics.
When using JET 1 technology, the soil is destroyed only by a cement morta jet. The mortar pressure 400-500 ATM.
JET1 drilling rods diameter -73, 89 mm.
JET1 tool includes the following elements:
For JET2 technology compressed air energy is additionally used. For separation cement mortar and compressed air supply to the monitor, double hollow rods are used.
JET2 drilling rods diameter - 89, 114 mm.
JET2 tool includes the following elements:
Jaws, hydraulic chuck cums for Figaro, Raptor, MDT, Casagrande, Comacchio, Beretta.
Bronze bushing for ССТ, Tecniwell.
Hammer shafts for Morath, EuroDrill.
Adapters.
