【摘要】：水压试验是确保输水管道安全、正常运行必须履行的项目,长距离、大口径输水管道水压试验管道分段多、水压试验压力产生的荷载大,因此水压试验总体费用较高,并且水压试验一般在管道施工阶段进行,试验完成后的大部分水压试验设施都要拆除,再次进行水压试验就会造成相关设施的重复建设和投资。对长距离、大口径输水管道采用全管段整体充水、分段静态升压的水压试验方式进行了研究,分析了管道分段和试验压力、分段处封堵设施、管道充水方式、水压试验主要步骤。该水压试验方式可有效降低管道水压试验费用,并可在运行中多次进行试验,便于工程的运行管理。该水压试验方式已在山东省胶东地区引黄调水工程黄水河泵站任家沟隧洞输水管道中得到了成功应用。
[Abstract]:Water pressure test is to ensure the safety of water pipeline, the normal operation of the project must be carried out, long distance, large caliber pipeline water pressure test pipeline sections, hydraulic test pressure generated by large loads. Therefore, the overall cost of water pressure test is high, and the water pressure test is generally carried out in the pipeline construction stage, and most of the water pressure test facilities after the completion of the test will be removed. Water pressure test will lead to repeated construction and investment of related facilities. The water pressure test method of long distance, large caliber water conveyance pipeline with whole water filling section and static boost pressure is studied. This paper analyzes the pipe segment and test pressure, the plugging facilities at the section, the water filling mode of the pipeline, the main steps of the water pressure test. The water pressure test method can effectively reduce the cost of the pipeline water pressure test. The water pressure test method has been successfully applied in the water conveyance pipeline of Rengjiagou tunnel of Huangshuihe pump station in Shandong Jiaodong region.
