摘要
辛克雷水电站所在河流含沙量大、电站水头高,泥沙对水库有效库容和水轮机磨蚀影响较大.针对工程突出的泥沙问题,根据"正向泄洪冲沙、侧向引水"的思路开展电站引水防沙体系设计,通过综合采用首部枢纽"四道防线"减淤排沙、水库拦沙及机械清淤等措施,使进入压力管道的泥沙含量达到设计含沙量的控制要求.设计方案可为同类型工程提供借鉴.
Abstract
The river where the Sinclair Hydropower Station is located has a high sediment content and a high water head,which has a significant impact on the effective storage capacity of the reservoir and the erosion of the turbines.In view of the prominent sediment problems in the project,the design of the water diversion and sand prevention system of the power station is carried out according to the idea of"flood discharge and sand flushing from the front,water diversion from the side".Through the comprehensive use of the"four lines of defense"of the head hub to reduce silt and discharge sediment,reservoir sediment interception and mechanical dredging,the sediment content entering the pressure pipe can meet the control requirements of the designed sediment content.The design scheme can provide reference for similar projects.
