In order to improve the piling quality and construction efficiency of sand piles,we develop a set of sand pile construction automation monitoring system and apply it on site,including automatic monitoring system for sand pile route,pile current monitoring system and remote monitoring system.The measured results show that the travel monitoring system can accurately record the sinking,lifting and reverse insertion distance of the sand pile tube;the current monitoring system can reflect the change of the sinking current in real time. By comparing the tube route and current monitoring results,we know that the current monitoring can reflect the changes of the pile formation and reverse insertion effect,and the tube route and current data can be displayed and recorded in real time via remote monitoring. The development of the system can realize the fine management of the sand pile,liberate the on-site supervision manpower and improve construction efficiency.
