Large longitudinal slope pipe jacking tunneling model test device

The utility model relates to a large longitudinal slope pipe jacking tunneling model test device. According to the technical scheme, the pipe jacking device is provided with a model box, a pipe jacking mechanism, a jacking mechanism, a tunneling mechanism and a pipe jacking supporting mechanism with the adjustable inclination angle. A test model soil body is filled in the model box, a soil body monitoring sensor is pre-buried in the model box, one side wall of the model box is formed by splicing an inlet hole baffle and a plurality of splicing baffles which are located at different heights, and a reserved jacking hole is formed in the inlet hole baffle; the pipe jacking mechanism is formed by coaxially inserting a plurality of standard pipe sections, the pipe jacking mechanism is arranged on the pipe jacking supporting mechanism at a certain inclination angle, one end of the pipe jacking mechanism is provided with the tunneling mechanism and penetrates through the reserved jacking hole to be inserted into a t
