2. Tunnel Drilling Machine
This presentation is based on the following information,
• Based on ATC specification document number C610‐ATC‐Y‐RSP‐CRG03‐50008 revision
1.0 dated 22/05/2014,
• Production for 1000 holes / shift – 8 hours / shift,
• Automatized production and positioning,
• Tunnel working environment and safety,
Specifications
• Rail/Road compact machine,
• Industrial Robotic arm for more accuracy and safety,
• Drill several holes diameters,
• Machine positioning with standard survey equipment,
• Use real Tunnel surface before drill,
• Uses CNC and CAM software to improve trajectories and drilling
performance,
• Dust management,
• Report for daily working and maintenance plan,
Operations
1. Transport or drive the machine on site,
2. Prepare the machine for working,
3. Prepare a survey total station,
4. Launch the software sequence for drilling,
5. Follow Software instructions,
6. Validate / Control position before drill,
7. Automatic Drill sequence with “bracket template”,
8. Drill next bracket,
9. If no more brackets in this area, move the machine
to next one,
10. End of work, park position,
11. Daily report,

3. Delta Drilling machine
Tunnel Drilling Machine
• The Delta Drilling Machine is a compact machine,
• The machine dispose of Rail/Road wheels,
• An industrial robotic arm assume the drilling position,

4. Positioning
Tunnel Drilling Machine
• Use standard survey total station (for example : Leica TS15 with Bluetooth communication),
• One reference prism is positioned on the machine,
• The Software measure and calculate the position of the machine and choice :
• To move the machine to the drilling zone,
• Or to Prepare for the drilling sequence,
• Another prism is positioned on the other side of the machine for assume both working direction,

5. Prepare drilling
Tunnel Drilling Machine
• Use 2 rotated laser to scan the tunnel surface (spacing around 1 meter),
• The Software generate two circles passing throw all best fit points and create a cylinder between
these two circles,
• The coordinates of the holes are projected on this surface to assumes
• The real position of each hole (bracket),
• The spacing of each bracket,
• A real depth of 150 mm,
• A dedicated CAM Software calculates the trajectory and drilling sequence (scripted automatically
with the Drilling machine Software) to assumes:
• the good positions,
• secure the movement of the drill bit,
• The specificity of drilling concrete sequence to preserve the drill bit and concrete, especially
during stages of starting and finish a hole,

6. Drilling sequence
Tunnel Drilling Machine
Drilling
• Use commercial Drilling tool with standard bit drill
adapted to C50/C60 concrete,
• A CNC equipment assumes and control the axis
movement and drilling sequence,
• This kind of system assumes all safety controls,
Dust management
A vacuum system is also installed on the machine
for dust management and a box with filter is
storing the dust. An additional system with a
compressor for pulse air into each hole is also
provide to be sure it was totally clean,

7. Reports
Tunnel Drilling Machine
• The Software can generate many reports
• Daily reports,
• Operations reports,
• Maintenance reports,
• PDF or excel format.

8. Safety
Tunnel Drilling Machine
• The Safety is assumed under and around the machine
• Respect the safety rules,
• Signalisations,
• Protections,
• Fire,
• Liquid,
• Materials,
• ...
