碩士 === 國立臺灣大學 === 土木工程學研究所 === 107 === Taipei City government is the first government to implement the design review of rainwater outflow suppression facilities, the relevant specification and reference data of drainage planning review, are constantly updated in order to meet the needs. The integration of Taipei City regulations and experience, helps the local authorities to establish the system and review measures, it is also helpful for professional engineers’ planning work, and base users’ maintenance and management. Therefore, this study is based on the regulations, specifications and literature of the design review of rainwater outflow suppression facilities in Taipei City, as well as the review opinions in 15 cases in recent years provided by the Taipei Professional Hydraulic Engineer Association. It is also recommended to add safety design and maintenance management regulations, as well as other counties and cities can develop adjustment factors, which are based on the meteorological data of climate zonation and rainwater sewer drainage standards, to apply the design regulations of Taipei City rainwater outflow suppression facility. Laws and regulations relating to rainwater outflow suppression facilities cover a number of areas such as sewers, rainwater channel, measurements, hydrographic analysis, hydrographic calculation and inspection, pumping system equipment, base development, architectural design, cadastral map data, Water Retention and permeable facilities, etc., and many related interfaces. This study will follow the order of the chapters and drawings stipulated in the "Taipei Drainage Plan Format" in collecting and organizing the data of review regulation, review opinions, matters to be considered, and the problems that may occur in the subsequent operation and maintenance management. In the process of study and consolidation, it can be found that some of the provisions and contents are slightly different or even repeated, because it has been published by official agencies, in order to maintain the integrity of the source, no additional deletion or combine is made. It is suggested that in the future the administration authorities may complete the reference manual and clearly inform the contents and precautions of each chapter, and may also provide more relevant examples about different types of rainwater outflow suppression, for the engineers to follow and reduce the error and revision during the review, thus speeding up the review schedule. About the design and configuration of rainwater outflow suppression facilities, the rainwater storage facilities are mainly divided into gravity drainage, mechanical pumping or both; the current case of the Taipei city, due to the constraints of space and low terrain, mechanical pumping is usually been chosen. In the other, in view of the characteristics of users, it is also necessary to evaluate the subsequent maintenance and management during the design process, so as to ensure the effectiveness of the facilities. The follow-up research can be revising the relevant regulations and manual. Interviews with the administration authorities, professional engineers and users, to further understand the relevant data, review, design, operation and maintenance of the rainwater outflow suppression facilities which are needed to be noticed in every phase, and the rolling review is needed to improve the mechanism and promote the facilities function.
