Abstract
Solving the problem of waterlogging is of great significance to the protection of historic districts and urban renewal. To solve the problem of waterlogging, it is necessary to comprehensively consider technical aspects such as the “Major-Minor-Micro” drainage system and the connection of urban/watershed flood control systems. At the same time, attention should be paid to the role of management in the entire system. However, there are a series of problems in the current waterlogging prevention and control system in China’s historic districts. The effectiveness improvement plan of the waterlogging prevention and control system is not sufficiently targeted. The various subsystems in the waterlogging prevention and control system play a role in poor coordination. The waterlogging prevention and control system does not work closely with the flood control system. Different management departments have weak coordination in the prevention and control of waterlogging. Aiming at the problems in the waterlogging prevention and control system in historic districts, this paper proposed a series of countermeasures. The waterlogging prevention and control system in historic districts should make full use of the current advanced concepts and practical experience of stormwater management. In order to enhance the role of the waterlogging prevention and control system in historic districts, specific issues should be analyzed in detail. The waterlogging prevention and control system in historic districts needs to be divided into different levels. The waterlogging prevention and control system should be aligned with historic attributes and be highly pertinent. The waterlogging prevention and control system should be closely coordinated with the larger-scale flood control system. At the same time, the intelligent management platform should be used to increase the supervision of the whole process of waterlogging in historic districts.
Highlights
The waterlogging prevention and control system is an important part of historic districts and plays an important role in historic districts and architectural heritage protection, urban renewal, environmental improvement, and improvement of residents’ quality of life
Chinese scholars have carried out some research on the waterlogging prevention and control system in historic districts
We analyzed the key problems of waterlogging in historic districts, examined the status quo of drainage systems in historic districts, and proposed specific countermeasures to improve the efficiency of waterlogging prevention and control systems in the context of protection and renewal of historic districts from the perspective of system efficiency improvement
Summary
The waterlogging prevention and control system is an important part of historic districts and plays an important role in historic districts and architectural heritage protection, urban renewal, environmental improvement, and improvement of residents’ quality of life. Chinese scholars have carried out some research on the waterlogging prevention and control system in historic districts. The Beijing Municipal Planning Commission carried out systematic research on the municipal planning technology of 25 historic and cultural preservation areas such as Beijing Nanchizi, and proposed plans and construction methods for the planning and transformation of municipal facilities such as water supply, heating, gas, and drainage under special conditions in the historic districts [1]. The current research on the drainage system of historic districts has not systematically analyzed the internal connections and key issues between the various links and systems involved in waterlogging. We analyzed the key problems of waterlogging in historic districts, examined the status quo of drainage systems in historic districts, and proposed specific countermeasures to improve the efficiency of waterlogging prevention and control systems in the context of protection and renewal of historic districts from the perspective of system efficiency improvement
