Can i put a step in a drain run? Down obviously not up, i would assume it needs to be rod-able from both directions but would it work?

I have a reinforced ground beam to get over. The invert of the drain is the same height at the middle of the ground beam so i was proposing 110mm pipe over the groundbeam, 2 90 degree bends to make a 'step' and then i can be at the correct level for the drain?
 
Is this outside?

If you could stretch it and use a couple of 45's it would be better.

Or make the first 90 a Tee, pointing down with riser to ground level and a 4D360 on top for access.
 
Have you room to create a manhole with the outet lower than the inlet?
I used a series of these to drop down from the house to a septic tank which was down a steep bank.
