摘　　要：太浦河泵站集水井超水位,出现基坑渗漏排水集水井漫水险情,文章结合集水井排水工作原理,分析了可能导致本险情发生的所有原因,并逐项进行排查,最终确定为渗漏排水泵出水管处止回阀内部阀板脱落,是导致外河水经由出水管路倒灌进入集水井内的主要根源。针对性地处置了险情,取得了良好效果,可为类似故障处理提供借鉴。At Taipuhe Pumping Station,an incident occurred where the sump exceeded its water capacity,leading to leakage and flooding in the sump.This paper,in conjunction with the principles of sump drainage,analyzes all potential causes that could have led to this hazardous situation.Each potential cause was systematically investigated,ultimately identifying the main source as the detachment of the internal valve plate within the check valve at the discharge pipe of the seepage drainage pump.This detachment allowed external river water to reverse flow into the sump through the discharge pipe route.Targeted measures were implemented to address the hazard,resulting in a successful resolution.This experience can serve as a valuable reference for handling similar malfunctions in the future.
