Model test device for simulating micro-disturbance construction of shield near-grounding structure

The utility model relates to a model test device for simulating micro-disturbance construction of a shield near-grounding structure. A soil box module comprises a soil box body, a soil body is arranged in the soil box body, a pile foundation module and a tunnel module are buried in the soil body, a shield tunneling module cuts the soil body, and a propulsion control module is used for propelling the shield tunneling module; the grouting control module and the muck improvement module are used for injecting grout and a muck improver, the underground water level control module is used for adjusting the height of the underground water level in the soil box body, and the ground pressure loading module is used for adjusting the pressure of the soil body; the data acquisition module comprises a data acquisition terminal and a sensor unit. Compared with the prior art, a plurality of modules are arranged, complex and diverse stratum conditions can be simulated, the construction disturbance influence of different shiel
