The construction process of the main beam by the cantilever casting method can be divided into formwork erection, reinforcement binding, concrete casting and maintenance, prestressed reinforcement tensioning and hanging basket forward movement. The quality of formwork erection directly influences the spatial position of the main beam after concrete pouring, thereby influencing the construction quality. The method for erecting the template commonly used in engineering comprises the following steps: firstly, a position which has a wide visual field and can longitudinally observe all sections of the main beam is found in the longitudinal extension direction of the bridge to be used as a paying-off reference point.
