VIII 木里河俄公堡水电站厂房土建及安装工程施工组织设计 2009年8月15日
第一章 综合说明
1.1 编制说明
由于调压井明挖未完及临时过河交通桥未形成，我单位自2009年6月4日进场以来至今未开始施工。根据目前调压井实际施工情况，调压井明挖预计在2009年11月中旬完成，我单位承建的发电厂房开挖要到2009年11月下旬才能开始施工。由于发电厂房实际开工时间延迟了近6个月。为了保证整个发电厂房总工期按合同工期要求完工，必须增加人力、物力、财力的投入，研究切实可行的赶工方案、制定赶工措施，同时科学地组织施工。
本施工组织设计是按照招标图纸编制的，施工图纸下发后可能有调整。编制前提是2009年11月21日发电厂房具备土石方开挖条件。 1.2 编制依据
俄公堡水电站厂房土建及安装工程施工组织设计编制的依据如下：
1、俄公堡水电站厂房土建及安装工程合同文件（合同编号：MLH-EGB-JJ/C4-6）； 2、俄公堡水电站厂房土建及安装工程招标图纸； 3、与本工程密切相关的部颁及行业施工规范、技术标准；
4、我局承担的类似工程的实际经验和我局现有的实际施工能力及技术装备水平； 5、现场实际情况。 1.3 工程概况 1.3.1工程总体情况
俄公堡水电站位于四川省木里河县境内的木里河上，为低闸引水式电站，其上一级为正在建设中的沙湾水电站，下一级为规划中的固增水电站。其取水枢纽位于沙湾厂房下游约25㎞处，于左岸取水后经长约14.8㎞的引水隧洞引水至小沟河口附近的厂址区建厂发电，工程右岸沿线现有S216省道通过。
俄公堡水电站工程的开发任务主要为发电，并兼顾下游生态环境用水要求。俄公堡水电站为低闸引水式电站，其正常蓄水位为2315.60m，电站设计水头77.5 m,额定引用流量191.1m3/s。电站装机3台，单机容量44MW，总装机容量132MW。
工程主要由首部枢纽、引水系统、厂区建筑物等组成。 1.3.2本合同工程概况
本标内建筑物主要包括：压力管道、厂房、进厂交通桥、小沟河改道。
