Especially the alluvial ground with high pressure tear the ground formed from the mixture of cement water mixture of the desired diameter and length of the column is to provide ground improvement. In the Jet Grout method the set works with the piercing machine, pump, boiler and silo.
Soil improvement aims to increase the mechanical strength values of the ground as a main function. Therefore, the load capacity and the modulus of elasticity increase, the permeability decreases. Jet Grout is the most successful method to achieve these goals. This method is the mixing of the floor with a stabilizer sprayed with a minimum pressure of 300 bar.
Stabilizers are generally a water-cement mixture (grout). The high pressure allows a high kinetic energy (speed) to pass through the delivered nozzles. High speed (200-250 m / sec) grout, ”tearing” the floor, provides a mixture with the soil (soilcrete). This mixture is a homogeneous and continuous structure.
