I need a technical cross-sectional illustration of a TBM (Tunnel Boring Machine) tunnel for use in a construction method statement.

The drawing should include:

• A circular TBM tunnel with segmental lining (precast concrete segments) clearly shown
• The excavation diameter and the annular gap between the segment lining and the excavation boundary clearly indicated
• The annular gap should be labeled (e.g., “Annular Gap”)

Additionally, I want to show a ground improvement application using our product called “DeepSoil”:

• Injection should be illustrated from inside the tunnel, through the segment lining, towards the annular gap and surrounding ground
• Injection points should be located at 10 o’clock, 12 o’clock, and 2 o’clock positions
• Arrows must clearly indicate injection direction from inside → outward (not from outside inward)
• The injected material (DeepSoil) should be visually represented filling/improving the ground around those مناطق

Style requirements:

• Clean, engineering-style technical drawing (not artistic)
• Clear labels and readable annotations
• Preferably a cross-section view with good depth perception
