摘要
作为城市排水系统的关键组成部分,排水管网的高效运行直接关系到城市基础设施的安全性和稳定性,因此,加快老旧排水管网的改造和破损修复意义重大。结合工程实例,以安徽省某市高新区市政排水管网修复提升一期项目为背景,深入分析了排水管网的缺陷类型与等级,探讨了开挖修复与非开挖修复方式的选择原则,明确了不同管径及缺陷类型所适用的修复方法,以期为类似工程提供决策参考和实践经验。
As a crucial part of the urban drainage system,the efficient operation of the drainage pipe network is directly related to the safety and stability of urban infrastructure.Therefore,it is of great significance to accelerate the renovation of old drainage pipe networks and the repair of damaged ones.Combining with engineering examples,taking the first-phase project of the restoration and improvement of the municipal drainage pipe network in a high-tech zone of a city in Anhui Province as the background,this paper deeply analyzes the defect types and grades of the drainage pipe network,explores the selection principles of excavation restoration and trenchless restoration methods,and clarifies the restoration methods applicable to different pipe diameters and defect types,aiming to provide decision-making references and practical experience for similar projects.
