摘要
桃源水电站二期工程截流龙口合拢按上游来流量不大于500 m3/s进行施工设计。根据水工模型试验及水力学计算成果,截流方式采用单向双戗立堵法截流,上、下游戗堤同时从右侧向左侧进占,仅上游单戗堤进行龙口合拢施工,取龙口宽度30 m时进行龙口合拢施工。截流施工中克服了分流条件差、准备时间短、备料不足等诸多困难,从截流准备到截流成功,只用了20余天。
The fiver closure construction for Phase II project of Taoyuan Hydropower Station is designed based on the gap discharge not greater than 500 ma/s. By hydraulic model tests and hydraulics calculations, the one-direction end-dump closure method is used for gap closure of two dikes. The bank-off advancing of upstream and downstream dike are carried out from right side to left side at the same time, but only the gap of upstream dike will be closed. The gap closing of upstream dike is conducted after the gap width being 30 m. The river closure is completed in about 20 days by overcoming the difficulties of adverse flow diversion, short preparation period and insufficient material preparation.
