三河闸水平位移监测系统研究与应用

Research and application of horizontal displacement monitoring system of Sanhe Sluice

采用“引张线+倒垂线”法进行三河闸水平位移监测,每块底板设置2个测点,共设置42套引张线仪,安装在启闭机房墙面。配套自动化监测系统,具有数据采集、管理、通讯、浏览等功能,亦具备人工比测条件,自动监测和人工比测精度相当,均达到有关标准要求。系统应用以来稳定可靠,为工程安全监测提供了技术支撑。

The method of“tension line plus inverted vertical line”is used to monitor the horizontal displacement of Sanhe Sluice.Each base plate is provided with 2 measuring points,and 42 sets of tension drawing line meters are installed on the wall of the hoist room.Equipped with automatic monitoring system,it has the functions of data collection,management,communication,browsing,etc.,and also has the conditions for manual comparison measurement.The accuracy of automatic monitoring and manual comparison measurement is equivalent,and both meet the requirements of relevant standards.The system has been stable and reliable since its application,providing technical support for engineering safety monitoring.
