PURPOSE: An impeller blasting system of a large-sized pipeline is provided to prevent an overturn of a trolley because balance is maintained and an upper supporting wheel is installed when a track unit of the trolley is moved along a pipeline. CONSTITUTION: An impeller blasting system of a large-sized pipeline comprises a track unit(102), a vehicle body(101), an abrasive supplying unit, an impeller jetting unit, and an upper support wheel. The balance of the track unit is maintained when moving in the inside of a pipeline. The vehicle body can be regulated upward and downward and leftward and rightward. The abrasive supplying unit is connected to the vehicle body and supplies an abrasive while rotating. The impeller jetting unit jets the abrasive on a surface of the pipeline. The supporting wheel prevents an overturn of a trolley.
