How can i get this kind of urls

It's up to you how you do it. I'll just say that google has no problem cataloging segments at all. It's a lot better than query strings and they are in a logical, organized manner. As I say, you can do it with single urls, but it will not be as efficient and it will be harder to build/maintain. It will make CI harder to use as you are going against the default behavior and will now have to manually route everything. Still, it's possible. I personally wouldn't do it that way. It's fine for some pages, like an "about" page, but I just create special routes for my 'single url' pages and the rest use CI normally.
