Review for urban drainage and waterlogging prevention system with dual use of normal and emergency situations at home and abroad
In order to cope with the excess runoff that exceeds the source emission reduction and the carrying capacity of rainwater pipes and canals,the dual-use drainage and waterlogging pre-vention system,as an important part of the urban large drainage system,can effectively reduce the urban waterlogging disaster and improve the urban waterlogging resilience.The concept of dual-use drainage and waterlogging prevention is defined,and different types of dual-use drainage and waterlogging prevention facilities and their functions are classified and analyzed in detail.Through the development status of dual-use drainage and waterlogging prevention systems at home and a-broad,the relevant policies and standards are mainly discussed.The shortcomings in the current theory and technical system of dual-use drainage and waterlogging prevention are pointed out,and the theoretical framework of dual-use drainage and waterlogging prevention is sorted out.Com-bined with practical cases at home and abroad,summarize the experience and put forward sugges-tions for the future development of dual-use drainage and waterlogging prevention.
