The invention discloses a tunnel multifunctional operation trolley which comprises a supporting seat, a first hydraulic oil tank is arranged in the supporting seat, four hydraulic bins are arranged at the positions, located at the two ends of the hydraulic oil tank, in the supporting seat, four hydraulic cylinder supporting legs are arranged at the positions, corresponding to the hydraulic bins, of the two sides of the supporting seat, and a piston rod capable of stretching out and drawing back independently is arranged in each hydraulic cylinder supporting leg. A fixed pointed end is arranged at the lower end of the piston rod, a fixed plate is arranged above the supporting seat, a lifting mechanism is arranged on the fixed plate, an operation plate is arranged at the right end of the fixed plate, and an objective table is arranged at the upper end of the lifting mechanism. The multifunctional tunnel operation trolley can be normally lifted and used on the flat ground and the slope, and the whole lifting process is more stable due to the fact that a scissor-fork type lifting mechanism and a hydraulic column supporting mode are adopted in the lifting platform lifting mechanism.
