algorithmic modeling for Rhino

Spiral Paths

Hey guys, 

I would like to model spiral ramps similar to the ones in the attached picture. 

I already figured out how to design the spirals in 2D in Grasshopper. The next step is to move the curve control points in Z-direction, but every start and end point should stay on the ground. I already tried to get it with kangaroo (springs + unary force) but didn't get a satisfying result. 

Thanks a lot.
