The invention provides a hydraulic plugging device for a grouting hole of a tunnel lining trolley, and belongs to the technical field of tunnel construction. The hydraulic plugging device for the grouting hole of the tunnel lining trolley comprises a delivery pump pipe, a gate plate and a bidirectional hydraulic jack, wherein the top of the delivery pump pipe is fixedly connected with a lining trolley panel; a first round hole communicating with the delivery pump pipe is formed in the lining trolley panel; a sliding groove for containing the gate plate is formed in the delivery pump pipe; the gate plate is arranged in the sliding groove in a sliding mode; a second round hole communicating with the delivery pump pipe is formed in the gate plate; the bidirectional hydraulic jack is fixed at the bottom of the lining trolley panel; a hydraulic rod of the bidirectional hydraulic jack is fixedly connected with the gate plate; the gate plate comprises a transverse plate and a vertical plate; and the vertical plate is vertically fixed onto the transverse plate. According to the design in the invention, the gate plate is pushed to a designated position in a hydraulic jacking mode, manual operation is replaced, hydraulic thrust is high, and even if sundries exist, the gate plate can be smoothly pushed, so that the effect of effective plugging is achieved, the purposes of convenience, rapidness, time and labor saving and easy operation are achieved, and the working efficiency is improved.
