Cut a TINsurface

I want to cut a TINsurface(original ground) with some plane-surfaces.

Now I have 4 surfaces to cut off a TinSurface(original ground). I’ve tried to use “Polysurface.ByJoinedSurfaces” node and close the TinSurface and cutting surfaces to make a cutting solid. However, I can select only “surface” but “TINsurface”, so I can’t get a closed solid. Is there any way to solve this?
