China News Service, Xiong'an, April 29th (Reporter Li Qian) On the 29th, a group of unmanned spreaders was unveiled on the new Rongwu high-speed line in Xiongan New District.
The first set of unmanned paving and compaction machines in China applied on the Rong-Wu high-speed new line realizes full-process digital construction through high-precision positioning and precise control methods, providing intelligent road construction solutions for the Rong-Wu high-speed new line and the construction of the Xiongan New Area Provide smart construction model.
The new Rong-Wu (Rongcheng-Wuhai) high-speed line is one of the external backbone road networks of the Xiongan New Area, and an important part of the "four vertical and three horizontal" expressway network planning in the new area. It is the main freight channel in the south of Beijing and Xiongbei. The transit corridor and the new district expressway north ring function conveniently connect Baoding and Tianjin. Its construction is of great significance to improve regional traffic conditions, relieve the transit traffic pressure of Xiongan New Area, and promote the construction and development of Xiongan New Area.
It is understood that the unmanned asphalt paving construction of the Rong-Wu high-speed new line adopts a joint construction mode of 1 paver, 2 rubber-wheeled rollers and 3 double-drum rollers. On-site pavers and rollers perform their duties. Carry out construction operations in an orderly manner, with quality and quantity.
Through the application of unmanned spreader and compressor group, people, materials, and time are saved.
It is reported that the use of this technology will save about 60% of manpower.
In order to give full play to the intelligent advantages of the unmanned spreader and compressor group, the Rongwu high-speed new line has tailored a local control platform and a digital construction cloud platform for the fleet.
Through the local control platform, plan and issue the operation path of the fleet to control the operation status of the fleet.
The digital construction cloud platform can monitor the entire construction process in real time, adopt a variety of quality inspection and feedback technologies, and control quality online.
And check the operating equipment in real time, and use data analysis and prediction to improve the utilization rate of the equipment.
It is reported that the unmanned paver cluster used on the new Rongwu high-speed line comes with multiple safety protection designs.
The first is the intelligent anti-collision protection. All machines in the cluster will predict based on high-precision positioning data and their own motion status, and automatically maintain a safe distance to ensure that there will be no collisions between the clusters.
The second is the electronic fence to ensure that the operating machine will not exceed the operating boundary.
The third is the emergency safety system. Through the two groups of front and rear radar systems, it can identify obstacles within 5 meters of the machine's traveling direction to ensure that the machine can automatically decelerate or brake when it detects obstacles or people. When the obstacle disappears, the road will be rolled. Automatically resume driving to ensure safety.
Finally, the unmanned equipment is equipped with an emergency stop switch, which can realize one-button stop in the face of emergency.
Zhao Wenzhong, deputy general manager of Hebei Transportation Investment Group, said that the first domestic unmanned paving and compaction machine group applied on the Rongwu high-speed new line integrates high-tech technologies such as artificial intelligence, automation systems, and multi-sensor fusion, through high-precision positioning and precision. The control method realizes the digital construction of the whole process, and provides road intelligent construction solutions for the Rongwu Expressway New Line. Through unmanned construction, it has not only created an industry model for the intelligent construction of the Rongwu high-speed new line, but also provided a sample of the application of “intelligent construction” on the Rongwu high-speed new line, helping the high-quality development of Xiongan New Area.
