Build smart! Sany unmanned intelligent paving machine group corps to fight in Anhui!

2023.06.15

On June 13, the construction site of Qinghai Road Project in Hefei City, Anhui Province, consisting of 2 pavers, 3 tandem rollers, and 3 setsTyre rollersThe composed Sany unmanned paving machine group performs its duties and carries out asphalt bottom paving construction in an orderly manner, which is also the first application of unmanned paving technology in municipal projects in Anhui Province.

Starting from June 13, the unmanned construction operation of the Sany unmanned paving machine group will carry out all-weather asphalt paving and rolling pavement operations in multiple road sections, using key technologies such as unmanned driving, collaborative scheduling, and group control safety to realize the intelligent operation and digital management of pavement construction, greatly reduce the number of operators, and complete high-quality and high-efficiency pavement pavement paving operations under the premise of ensuring safety.

In the construction process of the UAV swarm, the construction personnel only need to set the rolling trajectory, speed and other parameters of the construction section in advance, and the unmanned amortization machine group can automatically complete a series of tasks such as driving and steering, which effectively avoids the problems of leakage, overpressure, undervoltage, and overspeed that may be caused by manual operation.

Relying on Beidou high-precision positioning technology, the equipment can control the accuracy of the construction trajectory within 3 cm, and the self-developed high-precision curb recognition technology can realize the "zero welt" rolling of the road roller, which not only ensures the uniformity of paving and rolling and the degree of pavement compaction and flatness, but also effectively solves the common quality problem of insufficient edge rolling in conventional construction. Unmanned rolling machine group has remote control, one-key start and stop, adjustment of process parameters during construction and other functions, in the case of ensuring the supply of materials, can be all-weather continuous construction, the equipment is equipped with a quadruple safety control system, can prevent the occurrence of safety accidents, through the collaborative control of the machine group, resolutely implement the process principle of "keeping up with slow pressure", while improving the work efficiency of the unit, effectively guarantee the quality of the project and the safety of the construction.

According to the person in charge of the project, the application of Sany unmanned paving machine group not only saves manpower and improves construction efficiency, but also ensures the quality and safety of pavement paving compaction construction through precise control, and can also achieve continuous construction day and night to speed up the construction progress of the project.

Qinghai Road (Yellow River Road-Luzhou Avenue) and other seven roads and comprehensive pipe gallery project section 1 traffic engineering project is located in Hefei Binhu Science City, is the Luogang Central Park, Garden Expo Park surrounding supporting road projects. The unmanned paving asphalt was constructed by the consortium of Anhui Construction Engineering Construction Investment Group Co., Ltd. and Anhui Provincial Transportation and Navigation Engineering Co., Ltd., and organized and implemented by Anhui Xintu Building Materials and Sany Heavy Tools.

In addition to the successful application of automatic driving, artificial intelligence and other technologies, the successful implementation of the unmanned paving machine group in the asphalt bottom paving construction of the Qinghai Road project also provides strong support for the construction site to achieve comprehensive digital management relying on the construction management cloud platform.

The unmanned paving machine group of Sanyi Road Machine's digital and intelligent construction will also continue to take market demand as the benchmark to help the road construction industry draw a blueprint for green development and contribute to the unmanned and digital intelligent construction of roads.
