Human Factors
ZZZ has major surface construction in progress.Only a single taxiway to enter/exit the runway exists...all other entrances/exits were closed and barrier blocked.At [this morning] I taxied out for a local flight. On taxi I heard no one in the pattern or calling in nor did I see anyone in the pattern. I announced entering the runway to back taxi Runway XY. As I was back taxiing an aircraft reported overhead turning downwind for Runway XZ. At this point I was nearly into position for takeoff on [Runway] XY. There would have been no conflict whatsoever if the aircraft overhead had simply made a normal downwind and base leg; however that is not what happened. As soon as I announced takeoff on Runway XY the aircraft overhead announced turning final...the aircraft was barely on a downwind leg and had not even turned or even announced turning base for [Runway] XZ. The aircraft circled into a final approach for Runway XZ about 1/4 mile from the departure end of Runway XY.  I was committed to the takeoff and even if I had been able to clear the runway there were no runway exits for me to use to clear the runway. As I lifted off the aircraft maintained a straight on heading to my aircraft and forced me to turn left sharply at very low altitude barely above the tree tops.  I believe this was a malicious maneuver done intentionally to me. After I was clear of the runway environment the aircraft could have landed; but instead they announced a go-around.I am aware of the right of way rules and that an aircraft on final has the right of way to aircraft on the ground. However I believe the other aircraft abused the right of way rules to force me off the runway...which was impossible due to my already having begun my takeoff roll and the closed runway exits.
Pilot reported a NMAC during takeoff. On their takeoff roll; an aircraft on downwind for the opposite runway turned a short base and final leg to land. All remaining taxiways for the instructor were closed due to construction. The instructor became airborne and executed an evasive maneuver.
