吉牛水电站深厚覆盖层上闸首枢纽布置特点及其施工规划

吉牛水电站是革什扎河流域“一库四级”开发方案的第四级，为低坝引水式水电站。因发电工期提前一年．工程表现出工期紧、质量要求高、施工干扰大的特点．如不做好施工组织、规划，此单项工程很有可能成为制约发电目标的关键项目。、本文介绍闸首枢纽的布置特点、施工导流规划．通过实施阶段进度分析、主体工程及下一阶段施工重点进行分析与科学规划，为完成发电目标节点工期奠定坚实基础．

Jiniu hydropower station is the fourth rank of ＂one reservoir for four ranks＂ development program in the Geshiza river basin, which is the type of low dam diversion hydropower station. Based on one year advanced by generate electricity period, engineering show characteristics of the short construction period, high quality requirements and big construction interference, so single project is likely to the key projects restricted generate electricity goal when construction organization and planning has not been done well. The layout characteristics of lock head hinge and construction diversion planning are introduced with schedule analysis in the implementation stage and analysis and scientific planning the construction emphasis of the body project and the next stage, laid a solid foundation for completing node period of generate electricity goal.
