According to the documentation adding a third level of sub menu items to admin dashboard is possible by displaying as a tabbed navigation on top of the pages. But it is unacceptable for our project.
Could you please give advise how can I get menu like this:

+Menu 1
 Page 1
 +Menu 2
    Page 3
    Page 4

You can't. Unless you modify core. Then again, your requirements are not super-clear. What are the pages you have in there? Are we really talking about the admin menu, not the front-end menu? Would The Tree satisfy your requirements?
