| Research Abstract |
It has been frequently reported that concrete sewage facilities has deteriorated in short term than expected service life time of 50 years. This is serious problem in durability and maintenance of the sewage facilities. It is clear that this deterioration originates from sulfuric acid generated by the micro-organism activity in the sewage, thus nowadays a routine corrosion inspection of the sewage pipes is carried out. However, deterioration in sewage pipe has not well verified by current checking techniques, thus to ensure the required performance during service period is difficult.
In this study, the method for deterioration diagnosis for sewage pipes is investigated. As a result, the degree of deterioration can be examined, and methodology for estimation of service life with satisfies required performance of sewage pipe is proposed.
