Abstract:The design of the drainage engineering for the expressway network in Zibo involves the 142.74-km long rainwater pipeline, 5 rainwater pumping stations and the 72.48-km long sewage pipeline. In the process of cooperating with the road and bridge construction, the regional drainage channels have been perfected, the blank areas in the pipeline network have been eliminated, and the drainage standards have been improved. While implementing the concepts of sponge city, environmental protection and low-carbon constructions, the new materials, new equipment and new technologies are promoted and used.
