The invention discloses a large-compensation-amount heating and ventilation pipeline construction method. A large-compensation-amount heating and ventilation pipeline comprises a large-compensation-amount pipeline compensator and heating and ventilation pipeline bodies arranged at the two ends of the pipeline compensator correspondingly, connecting discs are fixedly arranged at the two ends of the pipeline compensator, and flanges are fixedly arranged at the ends, close to the pipeline compensator, of the heating and ventilation pipeline bodies. According to the large-compensation-amount heating and ventilation pipeline construction method, the heating and ventilation pipeline bodies and the pipeline compensator can be conveniently, rapidly and stably installed and fixed, the situation that the connecting positions of the heating and ventilation pipeline bodies and the pipeline compensator are loosened and leak due to thread loosening in the follow-up process is prevented, and therefore normal use of the heating and ventilation pipeline bodies in the follow-up compensation process is guaranteed; and meanwhile, the compensation process can be very stable, the defect that the stability is poor in the using process due to the fact that the compensation action is too large in the past is overcome, the structure is simple, and operation and use by people are facilitated.
