Zusammenfassung:The utility model discloses novel tunnel pressing equipment which comprises two annular steel frames, the two annular steel frames are fixedly connected to annular arch frames, square steel is welded between the two annular steel frames, and a transverse connecting beam is arranged between the annular arch frames. According to the utility model, the whole maintenance section does not need to be shut down for water filling pressure test, the pressing position is targeted, the water leakage position can be specifically seen, the labor and time of the water filling experiment are saved, the relative cost is low, the construction safety is better guaranteed, the joints are connected through bolts, the disassembly and the installation are convenient, and the construction efficiency is improved. The device can move in a pipeline, so that the construction progress is prevented from being affected by repeated disassembly, the pressing speed is increased, proper materials are selected, the overall weight of the device
