1、精选优质文档-倾情为你奉上摘 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2800kW,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=49.36 m3/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
2、,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AbstractBuild the water conservancy project building on the river , is concerning a great amount of peoples safety of life and property of low reaches .

10、施工”。在指导老师田林钢、曹震带领和帮助下,顺利完成这次设计任务,最终提交毕业成果。柳村电站施工在玉曲河上进行,受当地水温、气象、地形 、地质等因素影响很大。电站的建设,可解决左贡县城以及郊区设计水平年(2008年)及远景设计水平年(2015年)的照明电炊、取暖、部分农副产品加工、文化教育、行政等方面用电。拟定和选择柳村电站的施工方法,特别是导流方案的选择是本次设计的关键,坝址处的特殊的地形、河道宽度、地质条件都给布置导流建筑物带来困难,在本设计中共列出了6种导流方案进行论述,最终选择了分段围堰法的导流方案,并对此方案进行了施工总进度的编排。为了使理论和实践相结合,学校安排我们去四川瀑布沟、深
11、溪沟水电站施工现场进行毕业实习,在实习过程中,我有效的利用实习时间,掌握了很多施工组织知识为本设计打下了良好的基础。本设计参考了大量的文献、资料、手册,同时感谢田林钢、曹震两位老师对本次设计内容指导和帮助。柳村水利枢纽施工组织设计及主体工程施工设计1 柳村电站工程基本概况柳村河是怒江的一级支流,海拔5685m,河长402km,流域呈长方形。电站坝址以上流域面积5615.2km2河道平均比降5。流域内地势由北向南倾斜,地形复杂,河道由高山经高原进入河谷,河谷断面由“V”型逐渐过渡到“U”型。电站由左右岸非溢流坝段,厂房混凝土坝段构成。1.1 水文基本资料柳村河流域内没有水文站和雨量站,本次设计分
