data structure confusion

Hello, I am making a paper waffle structure of a form. Now I have 3 ribs in x directions and 10 ribs in y direction. Then I found intersections through BREP-BREP components.

Now I am confused how to join intersections curves with respective ribs in x direction. I am confused with data tree structure. I want three ribs with intersection curves joined respectively. In nutshell I am trying to get list of three closed curves with their intersection curves joined to them.
