Soil reinforcing method, e.g. for railway line construction, comprises mixing excavated soil and reinforcing material in chamber on top side of excavation machine

摘要

The soil excavation elements (3) pass through a mixing chamber (11) on the top side of the excavation machine, into which soil reinforcing material is added for mixing with the excavated soil. A number of excavation elements are made to rotate around an elongated, endless path, which is brought into contact with the soil layer and moved relative to the layer in a direction (R). An Independent claim is also included for the soil reinforcing machine.
