城市更新背景下地下管网更新改造策略研究

Research on Strategies for Renovation and Reconstruction of Underground Pipe Networks in Context of Urban Renewal

摘要:

城市地下管网作为城市重要的基础设施，其老化、漏损和安全隐患问题日益凸显，管网更新改造成为提升城市品质、保障民生安全的关键任务。通过梳理城市地下管网的现状，分析目前地下管网更新改造面临的底数不清、空间受限、协调困难、资金不足等技术与管理难题，总结管网更新改造成功经验，形成可复制机制。以城市更新为契机，建立“地下管线统筹改造”机制，从体检诊断、统筹规划、科技赋能、多元融资、标准构建等方面提出更新改造策略，为城市地下管网的更新改造、科学管理、安全运营和可持续发展提供保障。

Abstract:

As an important urban infrastructure, the underground pipe networks are increasingly plagued by problems such as aging, leakage and safety hazards. The renovation and reconstruction of pipe networks have become the key tasks for upgrading the urban quality and ensuring the livelihood safety of the people. By sorting out the current situation of urban underground pipe networks, the technical and management challenges faced in the renovation and reconstruction of the pipe networks, such as unclear baseline data, limited space, coordination difficulties and insufficient funds are analyzed, and the successful experience in the renovation and reconstruction of pipe networks is summarized to form the replicable mechanisms. Taking the urban renewal as an opportunity, a "coordinated underground pipeline reconstruction" mechanism is established, and the renewal strategy is proposed from the aspects of physical examination and diagnosis, overall planning, technology empowerment, diversified financing and standard construction, which provides a guarantee for the renovation, reconstruction, scientific management, safe operation and sustainable development of urban underground pipe networks.
