Horizontal static sounding calibration tank system and use method thereof

The invention relates to the technical field of indoor calibration of geotechnical engineering, in particular to a horizontal static sounding calibration tank system and a using method thereof. Comprising a soil sample tank, a glue bag and a horizontal injection device, a calibration tank top cover is arranged at the top of the soil sample tank, a calibration tank base is fixed at the bottom of the soil sample tank, a closed cavity is formed among the calibration tank top cover, the soil sample tank and the calibration tank base, a rubber water bag and a test soil sample are contained in the cavity, and the rubber water bag is located above the test soil sample. And a horizontal injection device is arranged on the side wall of the soil sample tank containing the soil sample in a penetrating manner. The device can simulate horizontal static sounding penetration under an actual soil layer stress condition, can provide a horizontal static sounding penetration stress condition close to a field for a soil body wit
