水利施工组织毕业设计--设计书

毕业论文第I页共56页摘要河流上修筑水工建筑物，关系着下游千百万人民生命财产安全。本设计主要论述了柳村水电站施工导流、导流建筑物的形式、围堰的结构设计及稳定分析、混凝土施工等。柳村电站枢纽位于西藏昌都地区左贡县境内怒江一级支流玉曲河上，为无调节坝后式小型水电站。该电站由拦河坝、泄洪建筑物、引水建筑物及电站厂房组成。电站设计装机容量为2×800kW，施工总工期2年。本枢纽导流建筑物为V级，电站施工导流设计流量采用平水年平均径流流量Q=49.36m3/s在导流方案设计时，分别采取了全段围堰法和分段围堰共6种方案的论述，经过技术和经济论证，最终采用分段围堰法施工。围堰材料采用草土袋，土工布防渗，经过抗滑稳定的分析，围堰符合设计标准。混凝土施工组织设计包括混凝土的配制，混凝土的浇筑，混凝土的温度控制，混凝土的养护，钢筋及模板作业等。柳村电站枢纽为浆砌石硬壳坝,混凝土施工主要在电站厂房坝段、溢流面、上游面板及下游消能池。关键词：施工导流，全段围堰法，分段围堰法，混凝土施工毕业论文第II页共56页AbstractBuildthewaterconservancyprojectbuildingontheriver,isconcerningagreatamountofpeople'ssafetyoflifeandpropertyoflowreaches.IsitexpoundthefactLiucunpowerstationconstructwaterconservancydiversion,form,structuraldesignandsteadyanalysis,concertconstruction,etc.ofcofferdam,waterconservancydiversionofbuildingmainlytodesignoriginally.ThehydropowerstationofLiucunlieswithintheboundariesofZuogongcountyofQamdoPrefectureofTibetonNujiangfirstclasstributaryYuquriver,fornotregulatingthesmall-scalepowerstationofthetypeafterthedam.Hydropowerstationbydam,releasefloodwaterbuilding,channelwaterthebuildingandhydropowerstationfactorybuildingmakeup.Designinstalledcapacity2×800kW,alwaysconstructsfor2yearsoftimelimit.ThispivotwaterconservancydiversionbuildingVgrade,hydropowerstationconstructwaterconservancydiversionadoptanddesigntheflowoffloodcrestwhilebeingthefirststageof49.36m3/s,adoptanddoesnotdesignflowinfloodseasonnon-whilebeingthesecondstageof117.5m3/s.Whenwaterconservancydiversionconceptualdesign,adopttheintergritycofferdamdamandhierarchiccofferdamdammethodsto6argumentationofschemeseparately,provethroughtechnologyandeconomy,isithierarchiccofferdamdammethodstoadoptfinally.cofferdamdammaterialadoptgrasssoilbag,geotechnologicalclothpreventionofseepage,throughisitslipsteadyanalysistoresist,thecofferdamaccordswiththedesignstandard.Theconcreteconstructionorganizationdesignsincludetheconcreteconfiguration,concreteconstructing,theconcretetemperaturecontrol,concretemaintenance,thesteelbarandthetemplateworkandsoon.ThehydropowerstationofLiucunplantskeypositionforlayswithmortarthestonehardshelldam,Theconcreteconstructionmainlyinthepowerplantworkshopdamsection,overflowstheflowsurface,upstreamthekneadingboardandthedownriverdisappearscanthepond。KeyWords:Riverdiversionduringconstruction,Intergritycofferdammethod,Hierarchiccofferdammethod,Concertconstruction毕业论文目录前言···········································································································1柳村水利枢纽施工组织设计及主体工程施工··························································21柳村电站工程基本概况·················································································21.1水文基本资料··················································································21.2洪水·······························································································31.2.1洪水特性···············································································31.2.2设计洪水··················································································31.2.3设计断面水位流量关系曲线······················································41.3地质·······························································································41.3.1库区工程地质条件···································································41.3.2天然建筑材料·········································································72施工导流设计····························································································82.1导流建筑物级别的确定.····································································82.2设计流量Q设的确定··········································································92.3围堰堰顶高程以上的超高d································································92.4导流方案·······················································································102.4.1导流方案介绍·······································································102.4.2全段围堰法导流····································································112.4.3分段围堰法导流····································································142.5总费用··························································································182.6方案比较························································································192.7施工导流建筑物设计·······································································202.7.1一期导流建筑物布置······························································202.7.2二期导流建筑物布置······························································212.8围堰结构设计················································································222.8.1一期围堰结构型式·································································222.8.2二期围堰结构型式·································································232.9围堰的稳定分析·············································································243专题设计：主体工程施工············································································273.1柳村电站混凝土概述·······································································273.2混凝土原材料及配合比·································
