High-pressure water jet double-slit coupling rock breaking tunnel boring machine

The invention discloses a high-pressure water jet double-slit coupling rock breaking tunnel boring machine, which comprises a cutterhead, injection devices and a high-pressure liquid generation device, wherein the first side surface of the cutterhead is provided with hobbing cutters; the movement trajectories of the injection devices are concentric and adjacent with the movement trajectories of the hobbing cutters; and the high-pressure liquid generation device communicates with the injection devices. The high-pressure liquid generation device and the injection devices are added, the movementtrajectories of the injection devices are concentric and adjacent with the movement trajectories of the hobbing cutters, and the high-pressure liquid generation device provides high-pressure liquids for the injection devices. During working, the high-pressure liquid generation device is started, the high-pressure liquids firstly carry out segmentation and sputtering on tunnel face rock through theinjection devices, so tha
