Application of Microcore Pile Monitoring Technology in Early Warning of Root Stone Loss in Yellow River Spur Dike
The loss of spur dike rootstones in the lower reaches of the Yellow River is an increasingly frequent problem,and traditional moni-toring methods have limited effectiveness.In order to improve the accuracy and scientificity of the early warning of missing rootstones,the mi-cro-core pile monitoring equipment was innovatively applied in the No.13,No.14,No.15 and No.20 spur dikes of the Yellow River Shendi control works to monitor the missing rootstones as well as the changes of the tilting angle of spur dike body,vibration impact and acceleration.The micro-core pile monitoring system utilized IOT integrated sensing technology to realize 24 hours all-weather monitoring of underwater root-stone operation status through sensing terminal.The application shows that when the foundation stone of spur dike slips under the action of water flow or external force,causing slight displacement,tilting or vibration of spur dike,the micro-core pile can sensitively capture the in-formation of these indexes,and the monitoring accuracy is high.
