The Gemara says that there is an argument whether we can combine a wall and a trench to make a ten T'faachim wall to make a Reshus hayachid.

Rashi explains that you surround the trench with walls, and now you have a hole ten T'fachim deep. Tosfos asks: that according to all is a Reshus Hayachid. The Mishna in Shabbos says that a well and its surrounding wall combine to make ten T'fachim for a reshus Hayachid.

Rather, Tosfos says, we refer that you made a wall five on the edge of the trench in order to surround the higher level. Since the inside of the Mechitzos is only surrounded by walls five T'fachim, they argue if you can combine the five T'fachim trench below the surface to a ten T'fachim wall.

Tosfos asks: we see a precedence by a post that's upper surface is full of nails (and you can't use the surface, which may make it loose its status of Reshus Hayachid) is still a Reshus Hayachid, since you may place a tray over it and carry. So why can't you say the same of this 5 T'fachim hill that surrounded by a five T'fachim wall, we should view it as a post ten T'fachim higvh, since you can put a tray over the walls?

Tosfos answers: we refer to a case where the walls are too far apart so you cannot put a tray over them.
