基于SMART原则的超大型城市排水泵站调研评估与分析

Investigation,Evaluation and Analysis of Municipal Drainage Pumping Stations in a Mega-City Based on SMART Principle

排水泵站是承担区域性的防汛和污水转输的重要基础设施,为保证和维持排水泵站能力的发挥,需要定期对泵站进行维护和大修。为实现城市排水系统精细化、科学化、智能化管理,确保新形势下上海的城市发展需求,应用基于SMART原则的“综合评价体系”对上海市属314座排水泵站的现状进行定量评估。将建设年代、泵站规模、运行情况、机械设备(机械设备维修情况和运行效率)、电气及自控系统、建筑结构、安全和标准化以及周边环境敏感度作为评价因子并确定权重,其中机械设备状况直接关系排水效能,因子权重最高。根据泵站现状对评价因子赋予相应分值,建设年代越久,泵站规模越大,设备故障率越高,更新改造次数越少,周边环境敏感度越高,评分越低,最后将各个泵站的各因子评分进行加权平均得到最终评分。评分从低到高进行排序,评分越低表明大修迫切性越高,由此确定泵站大修的优先级,为制定泵站大修计划提供规划依据。

Drainage pumping stations are important infrastructure for regional flood control and sewage transfer.In order to ensure and maintain the capacity of drainage pumping stations,regular maintenance and overhaul of the pumping stations are required.In order to realize the fine,scientific and intelligent management of urban drainage system and ensure the urban development demand of Shanghai under the new situation,the"comprehensive evaluation system"based on SMART principle(factor weighted scoring method)was used for quantitative analysis of 314 pumps of Shanghai.The construction age,pump station scale,operation condition,machinery and equipment(maintenance and operation efficiency of machinery and equipment),electrical and automatic control system,building structure,safety and standardization,and sensitivity of surrounding environment were taken as evaluation factors,and their weight was determined,in which,the condition of mechanical equipment was directly related to drainage efficiency,and its factor weight was the highest.Corresponding scores were assigned to the evaluation factors according to the status of pump station.The longer the construction age,the larger the scale of the pump station,the higher the equipment failure rate,the less the number of renovation,the higher the sensitivity of the surrounding environment,and the lower the score.Finally,the evaluation score of the pump station is obtained by weighted average.The score was ranked from lowest to highest,and the lower the score was,the higher the urgency of overhaul was.Therefore,the priority of overhaul of the pump station was determined,which provided the planning basis for making the overhaul plan of the pump station.
