During the construction of Hubei Huanggang Huangmei high-speed railway, Beidou based surveying and mapping devices have greatly improved the construction technology and project quality.
The construction quality and efficiency have been greatly improved compared with traditional construction operations.
During the construction of Shenzhen Mawan Cross sea Channel Project, in order to deal with the construction problems in the sea dumping and reclamation area, the project uses Beidou system, big data, building information model and other advanced technologies to comprehensively perceive the road and infrastructure construction, and conduct real-time online monitoring, greatly improving the construction accuracy and monitoring efficiency.
Using Beidou’s high-precision positioning function, the optimal operation path, construction speed, rolling passes, vibration frequency, amplitude, overlapping width and other parameters were planned according to environmental parameters, It can also realize automatic early warning, emergency stop and automatic obstacle avoidance.
Accurate and efficient intelligent construction has become an important trend.
Now, the integrated measuring device for catenary construction parameters based on Beidou and infrared scanning technology can integrate calculation and measurement, data sharing and other functions, and improve the efficiency of construction management.” During the construction of the south section of the Outer Ring Expressway in Xi’an, Shaanxi Province, Beidou high-precision positioning was adopted, and at the same time, inertial navigation, radar sensing and other technologies were integrated to achieve 24-hour uninterrupted, unmanned, intelligent and information-based construction of asphalt pavement paving and rolling, improve the operation accuracy, and improve the uniformity of paving, compaction and surface flatness, The cost is saved to the greatest extent, the construction quality and efficiency are improved, and a good foundation is laid for the safety and stability of the road.
In the stage of expressway construction, Beidou high-precision service has effectively assisted the installation and hanging of the main arch cable of the super large bridge, effectively improving the installation accuracy of the arch rib.
During the construction of China Laos Kunming Wanzhou Railway, which connects Kunming and Vientiane and adopts Chinese standards, the use of Beidou intelligent equipment has played an important role.
Only one person is required to control three equipment.
The bridge is of great significance for promoting the industrial interconnection between the east and west sides of the Pearl River Delta and the efficient configuration of various requirements.
The highway is located in Guizhou karst landform, and the special terrain environment brings many challenges and problems to the construction.
The equipment construction track accuracy can be controlled within 2 to 3 cm, which can meet the requirements of all-weather continuous operation.
During the subgrade construction of Lingtai Huating Expressway Phase I Project of Lingtai Huating Expressway of S28 Line in Gansu Province, Gansu Province successfully used the unmanned road roller equipped with Beidou positioning terminal to carry out subgrade collaborative rolling operation.
Guiyang Huangping Expressway Guiyang Huangping Expressway is open to traffic.
The relevant staff said: “In the past, the data was collected by people and entered into computers, but the data was not connected.
Based on Beidou and infrared scanning functions, the device can easily and quickly complete the measurement, recording and transmission of parameters such as catenary mast clearance, foundation elevation, span, catenary height, pull-out value, etc., so that the measurement error is controlled at the “millimeter level”, providing accurate data for later calculation and installation of cantilever and dropper parameters.
At present, Beidou’s wisdom and Beidou’s plan have been deeply integrated into all kinds of construction processes.

During the construction of the “pipe sinking transportation and installation integrated ship”, the Beidou system was used to dynamically monitor the whole installation process, and the pipe sinking was placed on the seabed at a depth of 40 meters, realizing accurate docking.
During the construction of this section of highway, Beidou has effectively assisted workers in safe construction.
As the road is located in Taklimakan Desert, with harsh environment, high temperature and high construction risk, the sand dunes move in windy and sandy weather, and the change of location makes workers easily get lost due to the loss of reference objects, so each person on the site is equipped with a positioning terminal based on the Beidou system to ensure that the construction personnel can obtain accurate location information in extreme environments and will not “get lost” in the desert, so as to achieve the goal of safe construction, No casualties occurred during the construction\|/ ★ The Beidou system is gradually changing the scene and face of the project construction, so that more accurate, safer and smarter construction can better benefit the people’s well-being.
The desert highway from Yuli County to Qiemo County in Xinjiang was officially opened to traffic.
In May 2022, Lingdingyang Bridge of Shenzhen China Channel (Shenzhen Zhongshan) will be connected to the catwalk of Lingdingyang Bridge of Shenzhen China Channel (Shenzhen Zhongshan).
