河口村水库导流洞是工程建设的控制项目，其开挖衬砌断面大、洞身长、进出口施工困难，能否按期完工关乎水库工程的顺利实施。通过分析导流洞工程的施工及建设条件，在确保工程质量与安全的前提下，提出了可行的施工设计方案。选择了导流洞与两条泄洪洞结合布置、运用的方案，即导流洞在非汛期为施工导流专用，汛期与1＃泄洪洞联合度汛；导流洞下闸封堵后经过龙抬头改建为2＃永久泄洪洞。为满足导流洞工程施工交通需要，沿河布置了连接导流洞出口与现状乡间沥青道路的3号施工道路，布置了从出口至进口的8号施工道路，同时为满足进出口上部开挖需要，布置了连接3号施工道路和泄洪洞进口的2号施工道路。根据总进度计划安排，导流洞工程与水库工程的场内2号道路、3号道路、建设管理营地及生活供水、施工变电站等列为项目的前期工程。导流洞施工时，变电站尚不具备供电条件，供电方案选择接引当地农用电，结合自备发电机。
河口村水庫導流洞是工程建設的控製項目，其開挖襯砌斷麵大、洞身長、進齣口施工睏難，能否按期完工關乎水庫工程的順利實施。通過分析導流洞工程的施工及建設條件，在確保工程質量與安全的前提下，提齣瞭可行的施工設計方案。選擇瞭導流洞與兩條洩洪洞結閤佈置、運用的方案，即導流洞在非汛期為施工導流專用，汛期與1＃洩洪洞聯閤度汛；導流洞下閘封堵後經過龍抬頭改建為2＃永久洩洪洞。為滿足導流洞工程施工交通需要，沿河佈置瞭連接導流洞齣口與現狀鄉間瀝青道路的3號施工道路，佈置瞭從齣口至進口的8號施工道路，同時為滿足進齣口上部開挖需要，佈置瞭連接3號施工道路和洩洪洞進口的2號施工道路。根據總進度計劃安排，導流洞工程與水庫工程的場內2號道路、3號道路、建設管理營地及生活供水、施工變電站等列為項目的前期工程。導流洞施工時，變電站尚不具備供電條件，供電方案選擇接引噹地農用電，結閤自備髮電機。

The diversion tunnel of Hekoucun Reservoir is a controlled project. Whether it can be completed on schedule,it will be related to the smooth implementation of reservoir engineering. The tunnel trunk is long with large section of excavation and lining and the construction of inlet and outlet is difficult. A feasible plan of construction design under the premise of ensuring quality and safety was put forward by analyzing the construction conditions of diversion tunnel. It chose the diversion tunnel combined with two spillway tunnels layout that was diversion tunnel dedicated for construc-tion diversion in the non-flood season,in flood season with spillway tunnel No. 1 for joint flood prevention. Diversion tunnel was converted into per-manent spillway tunnel No. 2 through dragon-head-raising after blocking. In order to meet the transport needs of the diversion tunnel construction, construction road No. 3 connecting outlet with the status countryside asphalt road was designed layout along the river. Construction road No. 8 was ar-ranged from outlet to inlet,as well as to meet excavation of upper open digging needs,arranged construction road No. 2 connecting inlet of spillway tunnel with construction road No. 3. According to the overall schedule,the engineering works of diversion tunnel,the 2nd and 3rd roads,management camps,domestic water supply and construction of substations were listed as the preparatory work. The substation was not provided with power during diversion tunnel construction. The power supply scheme was to use local farmers electricity combined with self-generating.
