水闸设计说明书

华北水利水电学院毕业设计I摘要江苏省某地区地势低洼，排水通道不畅，常常小雨小灾、大雨大灾，严重影响当地经济发展，为此当地政府决定疏通排水河道，加大排水能力，缩短排水时间，在排水河道末端兴建排水闸，改善地区水利环境。根据实际地势情况在该地区采用不设胸墙的开敞式水闸闸底板的高程采用河底高程，闸孔设置五孔。上游翼墙采用圆弧式翼墙，当翼墙插入岸体一定深度时采用重力式挡土墙；下游翼墙采用铅直的八字形翼墙，再采用悬臂式挡土墙。上游设置20m的铺盖，下游设置14m的消力池，池深0.6m，消力池后接18m长的防冲槽。关键字：闸孔计算；防渗排水；消能防冲；地基承载力；闸室稳定华北水利水电学院毕业设计IIAbstractGeographyincertainplaceinJiangsuprovinceislow-lyinganddamp,drainpassageChangnot,usuallythelightrainsmalldisaster,heavyrainbigdisaster,seriouslyinfluencealocaleconomydevelopment,decidetodredgeanddraincourseofriverforthislocalgovernment,enlargecatchmentability,shortenanddraintime,isdrainingcourseofriverbitterendandbuildingandliningupfloodgate,improvewaterconservancyenvironmentintheregion.Don'testablishtheadoptionbottomofriverGaoChengofGaoChengofthescaleboardoftheopeningofchestwallChangtypefloodgateZhaintheregion'sadoptionaccordingtotheactualgeographycircumstance,theZhaboreestablishesfivebores.Theupperstreamwingwalladoptionarctypewingwall,whenthewingwalladoptedagravitytypetoblockasoilwallwhileinsertingcertaindepthofshorebody;Thedownstreamwingwalladoptionleadkeepsofthehoroscopeformwingwall,againadoptionhanganarmtypetoblockasoilwall.Theupperstreamestablishesthebeddingwith20ms,thedownstreamestablishestheeliminatingof14msdintpond,ponddeep0.6ms,connecta18mtogrowaftereliminatingdintpondofdefendingandhurtlingslot.Keywords:Zhaborecalculation;defendtooozecatchmentandeliminatecandefendblunt;foundationloadingdint;Zharoomstability.华北水利水电学院毕业设计1目录摘要.......................................................................IAbstract..................................................................II第0章绪论............................................................1第一章基本资料............................................................1第二章闸孔设计............................................................42.1闸址的选择..........................................................42.2闸型的确定..........................................................42.3拟定闸孔尺寸及闸墩厚度..............................................42.4校核泄洪能力........................................................6第三章消能设计............................................................93.1消能防冲设计的控制情况..............................................93.2消力池尺寸及构造...................................................113.2.1消力池深度计算................................................113.2.2消力池池长....................................................123.2.3消力池的构造..................................................133.3海漫设计...........................................................143.3.1海漫作用......................................................143.3.2海漫长度计算..................................................143.3.3海漫构造......................................................153.4防冲槽设计.........................................................153.4.1作用..........................................................153.4.2工作原理......................................................153.4.3尺寸..........................................................153.5上、下游岸坡防护...................................................16第四章防渗排水设计.......................................................184.1闸底地下轮廓线的布置...............................................184.1.1防渗设计的目的................................................184.1.2布置原则......................................................18华北水利水电学院毕业设计24.1.3地下轮廓线布置................................................184.1.4校核地下轮廓线的长度..........................................194.2排水设备的细部构造.................................................194.2.1排水设备的作用................................................194.2.2排水设备的设计................................................204.2.3止水设备......................................................214.3防渗计算...........................................................214.3.1渗流计算的目的................................................214.3.2计算方法......................................................214.3.3计算渗透压力..................................................21第五章闸室布置...........................................................265.1底板和闸墩.........................................................265.1.1闸底板的设计..................................................265.1.2闸墩设计......................................................265.2闸门与启闭机.......................................................275.2.1工作闸门......................................................275.2.2检修闸门......................................................275.2.3启闭机类型....................................................275.2.4启闭机的选型..................................................275.3上部结构...........................................................285.3.1工作桥........................................................285.3.2交通桥........................................................295.3.3检修桥........................................................295.4闸室的分缝与止水...................................................30第六章闸室稳定计算.......................................................316.1设计情况及荷载组合.................................................316.2完建无水期荷载计算机地基承载
