Abstract
A device for simulating injections of liquid chemical/cementitious substances into soils, comprising a first observation chamber which delimits an injectable space adapted to accommodate a soil sample, a second observation chamber which delimits a perforation space adapted to accommodate at least one stretch of an injection device, with longitudinal extension along a longitudinal axis of the second observation chamber, wherein the first observation chamber and the second observation chamber are directly bordering to each other in an interface area, a retaining partition wall which can be inserted in the interface area so as to separate the injectable space from the perforation space and extracted so as to put the perforation space into communication with the injectable space, as well as first transparent portions formed in a first containment wall of the first observation chamber for viewing in real time a propagation of the chemical substance injected into the soil sample by means of the injection device. A method comprising a step of simulating by the device.
