[0002] Roads and bridges are indispensable infrastructure in modern life. They not only greatly promote social connectivity, but also provide great convenience for people's daily travel and significantly improve traffic efficiency. A well-designed drainage system can protect roads and bridges from waterlogging, maintain their structural safety, and ensure smooth traffic. Drainage pipes of roads and bridges are mostly made of reinforced concrete. This material has the advantages of high strength, good durability and convenient construction, making it the first choice for building efficient drainage systems. These drainage pipes are not only responsible for quickly draining rainwater and road surface water to effectively prevent water disasters, but also need to take into account the auxiliary support role of roads and bridges in structural design to ensure the stability of the overall structure. In order to further enhance the functionality and practicality of drainage pipes, we innovatively proposed a reinforced concrete drainage pipe with high external pressure bearing capacity.
