The construction of high-speed rail is a highly dynamic process, and the construction process is extremely complicated. With the rapid development of computer technology and the increasing popularity of Internet technology, and the Beidou satellite navigation system has become an important development strategy of the country, based on Internet technology Beidou positioning technology , With the help of digital technology, realizing the visualization, informatization and intelligent construction management of engineering projects has become an important development direction of engineering project construction management.
The Shanghai-Chongqing-Chongqing high-speed railway is the backbone of the comprehensive three-dimensional transportation system in the Yangtze River Basin. Its bridge-tunnel ratio accounts for 84.8%. Hi-Target installs a construction management system for all the machinery put into the construction site, and controls and assists the construction of pile foundations (CFG) in all bid sections with information technology. In addition, the Hi-Target Beidou pile driver intelligent construction management system provides real-time monitoring based on carrier phase observation. Dynamic differential positioning technology adopts dual-antenna high-precision Beidou positioning technology scheme. The selected pile points are guided by Beidou satellite signals, displayed in an intuitive plan view, and the offset distance between the pile head and the pile point is displayed in real time. Even novices can accurately Pile position calibration and piling construction. At the same time, the system's supporting cloud platform and mobile APP make it convenient for the owner, construction party, and supervisor to check the progress and completion of piling anytime and anywhere, and manage the construction project comprehensively and efficiently. Through the empowerment of Hi-Target, the construction of the Shanghai-Chongqing-Chengdu high-speed railway has achieved high-precision operations. Through the precise setting out of 3 cm, the project quality has been improved by more than 90%; the operation efficiency has been improved, and the work efficiency of the project has been improved by reducing manual setting out and guidance. 35%; saving cost input, data statistics, machinery, labor and material input reduced by 35%.
