浙江工业大学硬士学位论文■璺小型水电站设计及拦污系统研究摘要本论文以小京坞水电站建设为工程实践,结合浙江省水利厅科研项目“水电站迸水口清污系统研究”,探讨了小型水电站设计的总体技术方案和设备选型考虑的主要因素,并着重分析研究了小型水电站设计中普遍存在的进水口清污系统问题,取得了以下成果: ,包括:浆砌块石大坝、无压隧洞、引水明渠、压力前池、压力管路、厂房、电气设备和水力机械的设计及选型。 ,提高了水能计算的准确率和年发电量保证率。 ,对隐蔽工程实行边施工边设计方法,在保证水上建筑物安金斡前提下,节省十凡万元的钻探勘察资金。 ,,占压力前池总容积的40%,使压力前池的投资节省1l 8万元。 5。采用自应力钢丝网压力水泥管取代压力钢管,。 ,可使每一条引水山沟16%的弃水得到收集,,占该电站年产值6%。关键词:小型水电站设计,施工中断请求,拦污系统研究塑垩三竺查兰堡主兰垡堕苎:一一——二——————————————————————旦 DESIGN OF SMALL-SIZE HYDROPOWER STATION AND STUDY OF CONSERVANCY TRASH SYSTEM ABSTR ACT Thispaper uses thedevelopment process ofXiaoJingWu hy幽)pow盯 stat-ion aSen豳ee血g bines with theproject of“snldy诅 cleaIl曲g sVstem atinfallofhydropower statioff’,it discusses main tacto。s need tobeconsidered plan and equipment selectiot3 on thepervasxve prob‰1 w弛cIe锄g system at infallof-hydropower pap盯ackieV。s following results: the overall technical plan and construction drawing of Xia0YmgWu hydropower station,mcludmg tlaedesign andselection of stone dalIls,∞,pressuretunnels,channels,.pressure鹏ds,pressufe pipes,factofy buildings,elecU,ieal删瑚搿鼹船and埘araulic machineries. histoncal data ofwater flows parable hydropower 8tanons me calculation ofme water flowsofXiaoJingWu hydropower station, t0iInDrove uracy ofcalculation ofwaterpower and tOensure the outpm ofpower stationmeet thetargets· construct/on tO design-and build hidden proj僦8 塑羔三堂盔兰坐垡堕塞楚茎 can gnarant船the safety ofhydraulic buildings and save hundreds ofthousands Yuans ofexNomfion costs. thetermination of no—pressure tunnel by 50m to increase capacity ,which 40%oftotal capacity ofpressure pond.
