  The top triangle moose $(TTM)$ model, which can be seen as the deconstructed
version of the topcolor-assisted technicolor ($TC2$) model, predicts the
existence of the charged top-pions $ \pi_{t}^{\pm}$ in low energy spectrum. In
the context of this model, we consider photoproduction of $\pi^{\pm}_{t}$ via
the subprocesses $\gamma b\to t \pi_{t}^{-}$ and $\gamma \bar{b}\to \bar{t}
\pi_{t}^{+}$ at the large hadron-electron collider ($LHeC$), in which high
energy photon beams are generated by using the Compton backscatting method. We
find that, as long as the charged top-pions are not too heavy, they can be
abundantly produced via $\gamma b$ collision.
