When assembling the bridge, the bridge deck cannot be assembled quickly, which reduces work efficiency, and the guardrails above the bridge cannot be installed quickly. Therefore, a prefabricated modular bridge has emerged, which can quickly assemble the bridge deck and install the guardrails on the bridge deck, thereby improving efficiency and shortening construction time.
