With the transformation of China’s transportation infrastructure construction towards high efficiency, greenness, and industrialization, precast bridges have been widely used in engineering fields such as urban overpasses, highway trunk lines, and railway bridges due to their significant advantages of short construction period, controllable quality, and low on-site pollution.

As the core load-bearing component of the lower structure of a bridge, the construction efficiency and quality of pier columns directly determine the overall construction progress and structural safety and stability of the bridge.

This article combines current engineering practice to systematically explain the key technologies for rapid construction of precast bridge piers and columns, clarify the precautions for each link, and provide technical reference and practical guidance for engineering construction.
