tl;dr is there an easy way to drill a 90cm tunnel under paving

• I want to be able to keep my motorbike battery tender plugged into my bike while maintaining a clean footpath and no trip hazards, and not worrying about my charger getting nicked.
  
• Finance will not approve an external socket.
  
• we have a spare socket (that I currently use) in an outhouse down the alley.
  
• I have spare connectors to make my own super long extension cable.
  
• All paving is recent with a cemented in boarder and some pavers set and others cemented - I cannot remember which, but feel the footpath may all be cemented as a high traffic area.
  
  

I can work out how to run the cable neatly around the outside. The problem is how to get a cable across the footpath? I'm wondering if there is some sort of extra long sds drill bit I could rent/buy to span the 90cm path, then dig a hole in the bed either side and drill underneath, possibly running a bit of metal or plastic conduit to maintain the structure of the hole.
