RESEARCH ON AUTOMATIC MONITORING TECHNIQUE OF PIPE REPLACED BY BOX CULVERT JACKING PROCESS
箱涵顶进置换管幕顶推过程自动测量技术研究

Automatic real-time guidance measurement is the key to modern construction measurement.Nowadays,in China the new underground 3D traffic engineering method of pipe replaced by box culvert jacking is used,but the manual measurement can not meet the requirement of real-time monitoring.So a set of Total Station-based intelligent automatic guidance system has been developed thus could achieve the measurement automatically and improve work efficiency greatly.The principle and key technology of this intelligent guidance system is introduced.In the same time,combined with successful application of culvert jacking highway in the existing railway project in Shanghai Jinshan,this system proved practical and excellent with higher reliability and accuracy.
