姚巷荡排涝站工程安全鉴定分析评价

Analysis and evaluation on safety identification of Yaoxiangdang Drainage Station Project

安全鉴定是水利工程安全运行的重要保障,以无锡市鹅湖镇姚巷荡排涝站工程为例,对运营泵站工程的安全性进行全面评估。主要从工程规模、建筑物、机电设备、金属结构等4个方面对泵站工程进行安全鉴定分析,工程规模复核确定泵站在运行条件下承受的水位组合、特征扬程及流量;泵站建筑物复核抗渗、抗滑、抗浮和抗倾稳定能力,并评定安全类别;泵站机电设备复核水泵流量、电动机功率、装置效率,并进行机电安全评价;泵站金属结构复核拍门强度、拦污栅,并进行金属结构评定。同时,对泵站工程进行综合评价并提出安全维护建议,可为同类安全鉴定工程提供借鉴。

Safety identification is an important guarantee for the safe operation of water conservancy projects.Taking Yaoxiangdang Drainage Station Project in Ehu Town,Wuxi City as an example,the safety of the operating pumping station project is comprehensively evaluated.In this paper,the safety identification and analysis of the pumping station project is carried out from the four aspects of project scale,buildings,electromechanical equipment,and metal structure.Review the pump station in operating conditions to withstand the combination of water level,characteristic head and flow rate for the scale of the projet.Review the anti-seepage ability,anti-slip,anti-floating and anti-tilting stability,and evaluate the safety category;review the pump flow,motor power,and installation efficiency for the mechanical and electrical equipment of the pumping station,and conduct electromechanical safety evaluation;Review the metal structure of the pumping station.At the same time,a comprehensive evaluation of the pump station project and safety maintenance recommendations can provide a reference for similar safety identification projects.
