摘要
某工程所处的河流在汛期遭遇洪水,期间大量漂浮物随洪水涌入河道,污染水质,随河道湍急的洪水下泄,漂浮物壅堵在箱涵进口造成箱涵过流能力降低,涵前水位壅高,威胁下游的变电站和施工营地的安全。根据库区漂浮物的组成特点,结合汛后应急清理经验,提出应对措施,在涵洞进口上游安放拦漂设施,设置收集洪水漂浮物平台,防范或杜绝大型漂浮物在涵洞口壅堵,减小洪水和漂浮物对人员、财产安全的威胁,提高清漂效率。
The river where a project is located suffers flood a lot in flood season,during which large number of floaters flow into the riverwith flood and pollutes the water quality. The floaters discharge with turbulent flood,and block the inlet of box culvert,causingdecrease of flow capacity of the box culvert. With the increase of water level in front of the culvert,the safety of downstreamsubstation and camp will be threatened. According to the characteristics of floater in the reservoir area,and in combination with theemergency cleaning experience,counter measures are put forward,such as setting floater intercepting facilities at upstream of theinlet of culvert,and arranging platform for collecting floating debris to prevent or eliminate large floater blocking the inlet of culvert,reduce threat of flood and debris on the personnel and property safety,and improve the cleaning efficiency of floating debris.
