[0032] Specifically, see Figures 1 to 4 The cutting assembly 1 is the core power unit of tunnel excavation. After a certain period of excavation, the cutting assembly 1 stops working and the drilling assembly 2 is started to detect whether there is water in the depth of the excavation surface through drilling to ensure the safety of subsequent excavation. The cutting assembly 1 is the part closest to the cutting surface. The drilling assembly 2 is set on the cutting arm 11. Without moving the excavation equipment, its advantageous position is fully utilized to maximize the drilling depth of the drilling assembly 2, providing a basic guarantee for subsequent safe excavation.

[0033] See also Figures 1 to 4The working principle of the cutting assembly 1 is as follows: the cutting assembly 1 includes a cutting boom 11, a cutting slide 12, a slide column 13, a second telescopic cylinder 14, a pitch cylinder 15 and a cutting drum 16. The second telescopic cylinder 14 drives the cutting slide 12 to slide forward and backward along the slide column 13. The pitch cylinder 15 uses the cutting slide 12 as a fulcrum and drives the drilling assembly 2 to pitch through the cutting boom 11. The excavation equipment drives the cutting assembly 1 to the position closest to the cutting surface. The second telescopic cylinder 14 can drive the cutting assembly 1 to move forward and backward, thereby forming the first-stage forward and backward movement stroke of the drilling assembly 2, the purpose of which is to maximize the cutting surface. The drilling depth of the drilling assembly 2 is maximized; in order to reduce dust generated by the cutting assembly 1 during excavation, the spray assembly 3 is respectively arranged on both sides of the cutting arm 11, and the nozzle 31 of the spray assembly 3 is facing the cutting drum 16; the cutting arm 11 includes a horizontal portion 111 and a bending portion 112, the telescopic rail 21 is installed on the horizontal portion 111, the bending portion 112 is bent downward, and the transversely arranged cutting drum 16 is arranged at the end of the bending portion 112, and the cutting drum 16 is driven by the pitch cylinder 15 to perform cutting operation, and the downward bending portion 112 helps to increase the downward cutting force of the cutting drum 16.

The rotation angle of the turntable 24 is ±20°, that is, it can swing 20° left and right; under the action of the pitch cylinder 15, the swing angle of the drill arm 25 in the height direction can also be changed, so that the drill arm 25 has better flexibility and adaptability and a larger exploration range.

[0035] See also Figures 1 to 4The drill arm 25 includes a bracket 251, a power head 252, a propulsion cylinder 253 and a clamping mechanism 254.
