[0002] During the construction of a high-rise cable-stayed bridge, the pylons are typically constructed first. The main beams are then laid on either side of the pylons, and the bridge deck is then laid on top of the main beams. The installation of the bridge deck is also a crucial step in cable-stayed bridge construction. The deck serves as the roadway surface of a cable-stayed bridge, and its installation requires precise calculations and meticulous work to ensure a smooth and stable deck.
