Abstract:The adjustment of port cargo types is deeply bound to environmental protection policies,and has become the core path for the green transformation of ports.Aiming at the problems such as the significant increase in surface runoff of rainwater,the multi-party constraints on the path and scale of rainwater discharge,and the control of initial rainwater runoff pollution,we carry out a study on the drainage design of automated container renovation projects under restrictions.Using the methods such as qualitative and quantitative analysis and case studies,we combine the drainage concept of “infiltration,retention,storage,purification,utilization,and discharge” of municipal sponge cities with the operational characteristics of automated container yards and the actual situation of renovation projects,and summarize a sponge drainage design scheme suitable for the green renovation and upgrading of ports.The results show that by adopting the design scheme of using old strip stone paving between containers,decentralized rainwater storage tanks for peak shaving and pollution control,and joint drainage and regulation of the port area drainage system,the problem of rainwater runoff discharge gaps can be solved,the interception and disposal of initial rainwater can be realized,and the ecological benefits and engineering feasibility can be balanced.The results can provide a reusable technical path for the similar port automation renovation projects.
