本文结合发生劣化的工程实例,探讨了给水排水工程结构维护管理关系到结构的设计使用年限和城镇的可持续发展问题。强调了工程的设计方案、施工工艺、材料质量和运行期间可修复性的重要性。为今后给水排水工程的设计及相关规范的修订和编制提供参考。 In this paper, combined with the occurrence of deterioration of the project example, discusses the water supply and drainage engineering structure maintenance and management of the structure related to the design service life and urban sustainable development issues. The emphasis is on the design of the project, the construction process, the quality of the material and the importance of reparability during operation. It will provide references for the future revision and compilation of the design of water supply and drainage engineering and relevant norms.
