分析北京市内调水工程的水流条件,借鉴北京市水利工程及其他调水工程历史上出现的冰害典型事例,提出北京市内调水工程中涉及的明渠、取水口、水闸、过渠桥等,在冬季输水过程中可能存在的流凌、冰塞、渠道冻涨破坏、闸门冻结等冰害;并提出控制水流条件、装拦冰索、设潜水泵等相应的预防冰害措施,为确保冬季输水安全运行管理提供依据。
This paper analyzes the current conditions of Beijing water transfer project, draws lessons from the typical cases of ice damage in Beijing water conservancy project and other water transfer projects, and proposes the open channels, water intakes, sluices, In the process of water conveyance in winter, there may exist some problems such as flow and ice jamming, ice jamming, channel freezing up and freezing, gate freezing and other ice damage; and put forward measures to prevent ice damage such as controlling flow conditions, installing ice sheets and setting submersible pumps, To ensure the safe operation and management of winter water supply to provide the basis.
