Procedure; Human Factors
After received my landing clearance; I came in for landing. After I touched down on my mains for a wheel landing; during roll out; I was hit by helicopter rotor wash. My tail swung to the right with great force and I could not recover resulting in ground loop. I did not roll over; but my main gears folded back and prop tips sheared off. After reviewing the tower communication; it appears helicopter was hover-taxiing on [a nearby] taxiway and/or holding short on [my landing] runway. The helicopter was given clearance to taxi and hold short when I was on left base for landing.
