May 13，Over 1000 industry experts、Customer、Under the joint witness of media representatives，Sany Unmanned Pressing Machine Group on National Highway in 2023“Ping An Centennial Quality Project”Demonstration Creation Experience Exchange and On-site Observation Meeting——Unmanned intelligent construction has been completed at the construction site of the quality demonstration section of the third work area of Bid 1 of Jigongshan-Shangcheng Section of Dabieshan Expressway.，This is also the first time that the technology of unmanned compactor group has been applied in Henan Province.，It marks that the construction of Henan Expressway has entered a new era of unmanned intelligence.！

The section from Jigongshan to Shangcheng along the Dabieshan Expressway《Harmonious Planning Scheme of Expressway Network in Henan Province》Components along the Dabie Mountain Expressway，It is the eastern extension of the section from Minggang to Jigongshan along the Dabie Mountain Expressway.，It is a highway in Henan Province“13445 engineering”One of the projects。

The scene of the observation meeting，There are almost no operators.。Based on artificial intelligence、5G、Beidou high-precision positioning and other information technologies，BySSP130C-10 One paver、SPR300C-8 Two road rollers、STR130C-8 One road roller、AndSSR260C-8 Two road rollersA group of unmanned compactors.，Successful completion of paving of water-stabilized pavement、Initial pressure、Repressing、Final pressure operation task。

SANY Unmanned Pressing Machine Group PassedIntelligent collaboration technology，Road-based modeling、Autonomous path planning、Intelligent security scheduling、Speed coordination and other construction，Large data working condition storage function stores the equipment status in the construction process in real time.、Construction quality data and analysis，Traceability of construction data，Visualization of construction process and quality、Transparent。

SANY Unmanned Pressing Machine GroupIntelligent calibration technologyAutomatic calibration of key values of vehicle motion can be realized，Improve the level of machine intelligence，Rapid modeling through roads，Rapid digital model of construction road within half an hour can be realized，And utilize 3DAutomatic Leveling System to Achieve Millimeter Thickness Control，Obtain high quality intelligent construction pavement。

The project responsible person said.，Sany Heavy Industry is adopted for this section.Intelligent unmanned paving+Beidou high-precision positioning technology，Compare to traditional paving technique，HaveHigh precision、High dispersion、High efficiency、High security、High intelligence、Low costYes“5 high and 1 low”Characteristic，In practical application，It can realize millimeter-level leveling for water-stabilized construction、Centigrade positioning、Centimeter-scale welt compaction，On-line detection of rolling speed and other parameters，It effectively solves the problem of incomplete coverage of manual detection in traditional construction.、No whole process supervision and other issues，Measured compaction degree of water stabilized base、The qualified rate of strength reaches 100%，Plane accuracy error is 3cmWithin，Flatness、The thickness error is 50% higher than the standard%。

This 2023 National Highway“Ping An Centennial Quality Project”Experience Exchange and On-site Observation Meeting of Demonstration Establishment by China Highway Construction Industry Association、Henan Provincial Department of Transportation、Sponsored by Henan Communications Investment Group Co., Ltd.，Sany Heavy Work is the technical support unit.，Unmanned Pressing Machine Group Technology Obtained On-site Experts、Unanimous praise from customers。

This technology can improve the safety and accuracy of the construction process.，Achieve construction efficiency and quality safety“Double lift”，For construction“Ping An Centennial Quality Project”，Promoting High-quality Development of Highway Transportation Construction，Provides a reproducible，A road of quality construction that can be popularize and has practical significance。
