The utility model discloses a thin-wall hollow pier vent hole template which comprises a vent hole template body (1), and mounting pieces (2) with hollow interiors are arranged on the vent hole template body (1) and are symmetrically arranged on the two sides of the outer wall of the top of the vent hole template body (1). The vent hole template body (1) is of a hollow structure. The device is simple in structure and novel and reasonable in design; the thin-wall hollow pier can be repeatedly used for multiple times, can be disassembled and repeatedly used for multiple times, is good in construction economy, guarantees the forming quality of the thin-wall hollow pier after pouring, achieves pouring of the arc-shaped section of the ventilation hole, improves the construction quality, and meanwhile reduces the labor intensity and construction safety of constructors to the maximum extent.
