摘要
文中以南昌某大学校区排水管网检测项目为例,从管道的缺陷密度、结构性缺陷以及功能性缺陷角度进行分析并提出相应建议。结果表明,该校区排水管道总体缺陷密度为26.95处/km,其中,结构性缺陷密度为11.03处/km,功能性缺陷密度为15.92处/km。结构性缺陷主要以变形、破裂、起伏为主,功能性缺陷主要以沉积、结垢、树根以及障碍物为主,为便于排水管网系统更好地运行,应加强排水管道工程施工质量监管及管网系统的管护措施。
Taking the drainage pipe network inspection project of a university campus in Nanchang as an example,this paper analyzes the defect density,structural defects and functional defects of pipelines and puts forward corresponding suggestions.The results show that the overall de-fect density of drainage pipes in this campus is 26.95 per-km,of which the structural defect density is 11.03 per-km and the functional defect density is 15.92 per-km.The structural defects are mainly deformation,rupture and fluctuation,while the functional defects are mainly depo-sition,scaling,tree roots and obstacles.In order to facilitate the better operation of drainage pipe network system,the construction quality su-pervision and supervision of drainage pipe projects should be strengthened.
