碩士 / 國立臺灣海洋大學 / 河海工程學系 / 105 / The deployment of manhole covers is common in Taiwan. According to a survey conducted in 2007, there were approximately 2.5 million manhole covers built onto roads in this island, while the poll in 2016 indicated that as many as 320,000 manhole covers were present in Taipei City, out of which the rain manhole covers accounting for about 3%. Although the amount of manhole covers is small, issues including drop height, broken edges of manhole covers and noise prone to be present in busy traffic flow and improper construction and other factors. Furthermore, cases of damage or injury led by the manhole covers is usually reported in the news. Consequently, the maintenance, management and innovation of manhole covers is particularly significant.
This study mainly discusses the process of the emergency repair to manholes for the rainwater sewer in Taipei City and the analysis on the case factors. The first part introduces the related facilities, institutions with reporting errors and reasons of emergency repair. The second part contains the types and evolution of the manhole cover along with the reason of adopting anti-air-lifting manhole covers by the hydraulic engineering office. The third part mentions the longitudinal connection between the information maintenance system and the equipment management system. The fourth part walks through the overall process of applying for road permits and on-site mobile phone APP reporting in the road excavation management system. The fifth part reviews the relevant researches on the anti-air-lifting manhole covers and noise, discusses on and proposes for the emergency repair process of the existing manhole covers based on the statistical analysis of the relevant data in a period of three years, dated from March 1, 2014 to March 31, 2017.
Finally, the conclusion of this study shows that using anti-air-lifting manhole covers significantly reduces the maintenance case number in respective to the noise and cuts other hazardous factors of manhole covers. In addition, incorporating the instant messaging software, LINE on smart phone into the manhole emergency repair process allows problems to be resolved with less time and more efficient measures, which protect the safety of pedestrians and vehicles. It is expected that the relevant suggestions made by this study can be a reference for related units and engineering departments.
