Deeply-buried super-long highway tunnel TBM method and drilling and blasting method building device

The invention belongs to the technical field of tunnel engineering, and particularly relates to a deeply-buried ultra-long highway tunnel TBM method and drilling and blasting method building device which comprises a workbench, a base plate is arranged at the top end of the workbench, a pair of conveying rollers are symmetrically arranged at the two ends of the workbench, and a conveying belt is arranged on the surfaces of the conveying rollers. When the conveyor belt rotates, the inner surface is supported by the top of the base plate; a driving motor is arranged at the end part of the conveying roller; a shell part of the driving motor is mounted at the end part of the workbench; according to the construction device for the deeply-buried ultra-long highway tunnel through the TBM method and the drilling and blasting method, the abutting rollers are arranged and continuously extrude the inner surface of the conveying belt when the conveying belt rotates, so that the conveying belt is tightened, the output quan
