万家寨引黄入晋工程一级泵站安全监测设计

万家寨引黄入晋工程总干线一级泵站是引贡的第一级提水工程,属于高水头、大流量、多机组的大型抽水工程,为保证泵站的正常运行,必须对此泵站进行安全监测。安全监测设计原则是“突出重点、兼顾全局,以自动遥测为主”。根据泵站的地质条件地下建筑物的特点及运行管理的需要,在地下水厂房洞群、调压井、高压管道等重要部位布置有围岩变形、结构尖力和应变、渗压、接触缝等监测项目。根据施工 运行期的特点设计了一套自动化采集系

Design of safety monitoring system for a pumping statiom

The grade I pumping station with high head, large discharge and multiple units on the trunk canal of the Wanjiazhai Project diverting water from Yellow River to Shanxi Province is the first-stage water-lifting works of the diversion project. In culer to ensure safe operation of pumps, safety monitoring should be conducted. The principle for the design of safety monitoring is "laying stress on the key points, giving consideration to comprehensive situation, and taking auto-remote monitoring as the main means". According to the geologic condition of the pumping station, characteristics of the underground structures and requirements for operation and management. monitoring programs related to the deformation of surrounding rock, the stress, strain, seepage pressure and contact joint of structures are arranged in the important positions of the chamber group of the underground powerhouse, sump shaft, penstock. An automatic acquisition system has been designed in accordance with characteristics of the pumping station during the construction and operation periods.
