In the context of topcolor assisted technicolor(TC2) models, we study the production of the top-pions $pi_{t}^{0,pm}$ with single top quark via the processes $pbar{p} to tpi_{t}^{0}+X$ and $pbar{p} to tpi_{t}^{pm}+X$, and discuss the possibility of detecting these new particles at Tevatron and LHC. We find that it is very difficult to observe the signals of these particles via these processes at Tevatron, while the neutral and charged top-pions $pi_{t}^{0}$ and $pi_{t}^{pm}$ can be detecting via considering the same sign top pair $ttbar{c}$ event and the $ttbar{b}$ (or $tbar{t}b$) event at LHC, respectively.
