Yangzhou first used RFID and millimeter-level 3D intelligent paving and other technologies to create roads.


Using 3D technology to "print" road pavement, have you heard of such road-building technology? The reporter learned from the traffic and highway department yesterday that the city recently tried to use the millimeter-level 3D intelligent booth in the renovation and expansion project of the 333 provincial road Baoying section. Shop technology. Yesterday, the accuracy of the “printed” road surface improved by 3D technology was increased by more than 30%. The success of this test means that this technology is expected to be widely promoted in the traffic engineering of the city in the future.


The reporter saw at the construction site that the asphalt paver slowly moved forward, spreading the mixed asphalt evenly on the road surface, and displaying the asphalt temperature and paving speed in real time. “Traditional paving construction technology requires multiple points to measure the elevation, measure the temperature, complicated measurement work and the superposition of errors, which makes the field workers miserable.” Ling Gaoxiang, head of the scientific research service unit, introduced 3D intelligence on asphalt surface layer. The paving system was developed by Jiangsu Dongjiao Group to make asphalt surface construction simple and efficient. The system achieves positioning accuracy within 3 mm by tracking the optical targets on the pavilion, allowing accurate control of paving thickness and slope. In order to further ensure the construction quality, the asphalt pavement control system is also used in the construction process. Real-time data collection and transmission of asphalt mixing, transportation, paving and rolling are realized through technologies such as Internet of Things, automatic data collection, high-precision positioning and RFID. , analysis, evaluation, early warning, when the data exceeds the warning threshold, immediately prompt the construction personnel to deal with it in time, so as to improve the overall quality of the project.


Compared with the traditional construction mode, using digital construction technology, the construction workers are reduced by about 40%, the work efficiency is increased by about 50%, the paving accuracy is improved by more than 30%, the control precision is truly achieved in the millimeter level, and the potential quality hazard is greatly reduced. Do the whole process of construction quality control.
