Abstract
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.关键词
