由举世瞩目的港珠澳大桥成功应用“激光法沉管测量定位”技术,该技术根据激光的准直性原理,消除大水深测量塔挠度变形影响,实现对沉管的精确定位,系世界首创。目前,测量仪器和测量系统已形成数字化、智能化和集成化的新发展态势。三维可视化测量系统,可根据用户施工安装测量定位需求,选用全站仪、GPS、测距
The “Hong Kong-Zhuhai-Macao Bridge” attracting worldwide attention has been successfully applied “laser method immersion tube measurement and positioning” technology, which can eliminate the influence of deflection and deflection of large water depth measuring tower and realize accurate positioning of immersed tube according to the principle of laser collimation The world’s first. At present, measuring instruments and measuring systems have formed a new trend of digitization, intelligence and integration. Three-dimensional visualization measurement system, according to the user construction and installation of measurement and positioning needs, use total station, GPS, ranging
