[0020] Embodiment 1:

[0021] According to Figure 1 and Figure 2 shown, a drilling device suitable for reservoir tunnel construction includes a leg rock drill main body 1; a support assembly placed at the bottom end of the leg rock drill main body 1, the support assembly includes a rectangular plate 2, two telescopic legs 3 and an L-shaped plate 5, the L-shaped plate 5 is fixedly installed on the side of the top end of the rectangular plate 2, and both telescopic legs 3 are hinged to both sides of the bottom end of the rectangular plate 2.

[0022] Rubber blocks 4 are fixedly installed at the bottom ends of both telescopic legs 3, and magnetic strips 14 are correspondingly installed on the inner walls of both telescopic legs 3.

[0023] An arc-shaped support 12 is slidably connected to the middle of the top end of the L-shaped plate 5. The sliding connection ensures that there is space for the leg rock drill main body 1 to move forward during the drilling construction process. The inside of the arc-shaped support 12 is filled with shaping mud 13, and the shaping mud 13 better adapts to the bottom shape of the leg rock drill main body 1, thereby making the installation of the leg rock drill main body 1 more stable.

[0024] During specific use, for a drilling device suitable for reservoir tunnel construction of the present utility model, it is planned to use the drill and blast method for reservoir tunnel excavation, full-section blasting excavation. Starting from the portals of the branch tunnels at both ends of the self-diversion tunnel, tunneling is carried out at both ends, with a cyclic footage of 2.2 - 2.5 meters. YT-28 (leg drill) is selected for drilling, inclined hole cut is used, and smooth blasting construction is adopted for the perimeter holes. When using the leg rock drill main body 1 for drilling, first place the leg rock drill main body 1 above the shaping mud 13, knead the shaping mud 13 to make it more conform to the bottom of the leg rock drill main body 1, then adjust the height of the telescopic legs 3 to a suitable position, and then start drilling. After the drilling is completed, retract the telescopic legs 3, and adsorb the two telescopic legs 3 together through the magnetic strips 14 for easy carrying and storage.

[0025] Embodiment 2:

[0026] On the basis of Embodiment 1, as Figure 1 and Figure 3As shown in the figure, the dust suction assembly is placed below the main body 1 of the leg rock drill.

Filter meshes are installed on the plurality of suction holes 11. The filter meshes are used to filter smaller debris and dust, and the slightly larger debris falls on the ground naturally.

[0028] Both sides of the bottom end of the rectangular box 7 are fixedly installed with inclined boxes 8. The two inclined boxes 8 are communicated through a connecting pipe 15. Spray heads 16 are installed on the inner sides of the two inclined boxes 8. A water inlet pipe is fixedly installed on the outer wall of one of the inclined boxes 8.

[0029] During specific use, for a drilling device applicable to reservoir tunnel construction in the present utility model, during the drilling process, the industrial air pump 17 is driven. The industrial air pump 17 generates suction force. The suction force enters the inside of the annular box 10 through the air pipe 9, and then smaller debris and dust are absorbed through the suction holes 11 on the annular box 10. The slightly larger debris falls on the ground naturally. While sucking dust, at this time, one of the inclined boxes 8 is communicated with an external water source through the water inlet pipe. The external water source enters the inside of one of the inclined boxes 8, and then enters the inside of the other inclined box 8 through the connecting pipe 15. Then, the water inside the two inclined boxes 8 is sprayed out through the spray heads 16 to reduce dust at the drilling construction site, and also improves the visibility at the drilling construction site, avoiding dust overflow and affecting the line of sight at the drilling construction site.
