From time to time, someone asks whether it is possible to learn or practice push hands without a partner or a teacher. My own feeling is that this is not really possible; however, once you have a certain foundation, doing solo form or other exercises can indeed improve your push hands.
I remember being very frustrated by not having a partner to practice with or a framework similar to the solo form. My solution was to travel to see a teacher in order to receive some instruction and then to make a concerted effort to find (a) regular practice partner(s) in my area. Although I am eternally frustrated by my rate of progress, I nonetheless feel that I have a tremendous amount I can work with and am reasonable satisfied with my practice regimen. During a practice session, I am never able to come close to exhausting all the drills and applications I would like to practice. In other words, I now find that I have more than enough material to work with.
Before I found my current solution, I did happen on a practice that I found interesting and that thought I might share here for those who have no alternatives. What I did was roll around a Swiss exercise ball against a wall, using both sides of my forearms and my palms. What I got from doing this was a little sense of the different pressures that were possible and how to feel them throughout my frame. I also got a sense of how closely and consistently one must stick to maintain the desired pressure.
These exercise balls have a slightly sticky surface that gives good feedback during rotations. It does not allow any slippage. This characteristic made clearer for me one reason why Taiji sticking requires such precise rotation.
As I stated at the beginning of this post, I do not think it is really possible to learn or practice beginning push hands without a partner; however, I think this exercise can still give a taste for those who have no other alternative and little experience of the real thing. By rolling back and forth among Push, Rollback, Press, and Wardoff, you can get some sense of what Push Hands trains and how these jins might be used.
Take care,

It could take me awhile though. I don't have any tiger-proof socks.
