These vertical brackets are a special form of arpeggio; see 6.6.7 Arpeggio.

... or was your question how to get _two_ of them?  I would guess that 
this would be relatively easy, although you might have to move the 
Arpeggio Engraver into the Voice context instead of a Staff. 
Unfortunately I don't have the time to play with this right now.
