新华社呼和浩特7月26日电(记者贾立君)记者在黄河海勃湾水利枢纽管理局了解到，几天来海勃湾水利枢纽积极化解今年第2号洪水，截至26日下午，上游来水量与出库水量持平，各项监测数据正常，洪水正在平稳经过黄河内蒙古乌海段。 为应对此次洪水过程，位于内蒙古自治区乌海市的黄河海勃湾水利枢纽7月23日0时起，逐步降低水库水位，出库流量按不超过每秒3000立方米控制下泄，至坝前水位降至1071米，腾出防洪库容。 同时，启动排沙调度运用。 几天来，黄河海勃湾水利枢纽管理局24小时密切关注水情、汛期发展变化，强化水库运行和大坝安全管理，加强对水库左右岸、重要部位特别是险工段巡查防护工作，确保安全度汛。 截至7月26日17时，海勃湾水利枢纽入库流量每秒2760立方米，出库流量每秒2760立方米，坝前水位1071.5米。 目前，泄洪闸坝段、土石坝段及尾水边坡等水工建筑物正常，各项监测数据在正常范围内波动，黄河今年第2号洪水正在平稳经过内蒙古乌海段。
Xinhua News Agency, Hohhot, July 26 (Reporter Jia Lijun) - The reporter learned from the Haibowan Water Control Project Administration of the Yellow River that the Haibowan Water Control Project had actively resolved the No.2 flood this year in recent days; and as of the afternoon of the 26th, the upstream inflow was equal to the outflow, the monitoring data were normal, and the flood was smoothly passing through Wuhai section of Inner Mongolia of the Yellow River. In order to deal with the flood, Haibowan Water Control Project of the Yellow River located in Wuhai City, Inner Mongolia Autonomous Region gradually lowered the reservoir water level from 00: 00 on July 23, and the outflow rate was controlled to be less than 3000 cubic meters per second, until the water level in front of the dam dropped to 1071 meters, freeing up flood control capacity the reservoir. At the same time, the operation of sand discharge scheduling was started. In recent days, the Haibowan Water Control Project Administration of the Yellow River has paid close attention to the development and changes of water regimen and flood season for 24 hours, strengthened the management of reservoir operation and dam safety, and strengthened the inspection and protection work on the left and right banks and important parts of the reservoir, especially dangerous sections, to ensure the safety during flood season. As of 17: 00 on July 26, the inflow and outflow of Haibowan Water Control Project were 2760 cubic meters per second and 2760 cubic meters per second respectively, and the water level in front of the dam was 1071.5 meters. At present, hydraulic structures such as spillway dam section, earth-rock dam section and tailrace slope are normal, and various monitoring data fluctuate within the normal range, and the No.2 flood of the Yellow River this year is passing through Wuhai section of Inner Mongolia smoothly.
