Setting-out method of road excavation/filling line by using BeiDou/GNSS RTK technology

WEI Yan-zhong;Construction &Installation Engineering Co.Ltd.of CR11BG;  
It is vital important to determine excavation/filling line properly in road setting-out engineering.Combined with BeiDou/GNSS(BeiDou Navigation Satellite System/Global navigation Satellite System)advantages,the decision condition of excavation/filling point is given,and the setting-out method of road excavation/filling line by using BeiDou/GNSS RTK(Real Time Kinematic)technology is proposed.The main operation steps of this method are:according to the designed cross-cectional profile,the coordinates of approximate excavation/filling point and its five meters neighbor interpolation point are calculated;then the two points are located by using RTK.And according to the decision condition of excavation/filling point,the real excavation/filling point will be gotten progressively in the direction determined by the two settingout points.In the process of construction,the validity of the setting-out excavation/filling point is proved further by using the border points of the final stage for heaping soil and brocken rock,or by using the knee point of the first filling side slope.The application results show it is a valid setting-out method of road excavation/filling line.
