The scorching sun is as red as fire，The construction is just in time。Trinity“Black technology”Unmanned compactor group goes to Nanjing，Help Nanjing General National and Provincial Highway Maintenance Large and Medium-sized Repair ProjectSLishui Section of Ninglang Line 246。

At the construction site，There are almost no operators.。By1 setSAP130C-8 Paver、2 setsSPR300C-8 Rubber-tired roller、3 setsSTR130C-8 double drum rollerThe group of unmanned pressers performs their respective duties.，Jointly carry out asphalt pavement、Initial pressure、Repressing、Final pressure and other operations，The speed of action、The accuracy of the trajectory was repeatedly praised by the on-site personnel.。It is understood that，This is also the first application of UAV group construction technology in the maintenance project of ordinary national and provincial roads in Nanjing.。

Introduction of on-site staff，The operation content of Sany Unmanned Pressing Machine Group is 246 Provincial Highway in Jiangsu Province.（Ninglang line）K74+000-K75+000 segments，Full length 1km，Construction width 8.2m，The construction content is the upper layer of asphalt.，Thickness of asphalt loose laying is 4.8cm，The construction section is located at the intersection of longitudinal slope and curve of the line.，Longitudinal slope of the line is about 7%，Curve radius approx. 700m，Adopted for construction“1stall+Two pairs+2 Glue+1 pair”The fleet is equipped。

Provincial Highway 246（Ninglang line）From Nanjing Ring Road，Southward through Jiangning District、Lishui Development Zone、Dongping、Yongyang、Crystal Bridge、Behind the lacquer bridge in Gaochun，To Jingnei, Langxi, Anhui Province，It is also known as Ninglang Highway.，The total length is about 92 kilometers.，The Jiangning section is 32 kilometers.，Lishui section: 45km，Gaochun section 15 km，It was opened to traffic in 2011.，It is the longest trunk highway in the history of Nanjing highway construction.，Yeah, too“The 12th Five-Year Plan”The first trunk highway completed in Nanjing during this period。

This unmanned paving operation is carried out twice.，300mTest section+700mFormal construction section，During construction，Provincial Department of Communications、Zhenjiang Road and Bridge and other leaders at all levels、Experts came to the scene to observe and exchange.，The operation effect of the field cluster has been unanimously recognized and praised by the field experts.。After the completion of the construction, the construction party shall conduct coring and quality inspection in the later period.，Flatness of unmanned paving operation section、Compactness、Permeability rate，The qualified rate of key indicators such as thickness has reached 100%，The quality of the project is good。

“The quality of the operation of Sany Unmanned Pressing Machine Group has reached the relevant standards.、Specification requirements，The labor cost is saved in terms of cost.，Reduce the probability of risk occurrence in terms of safety，For the road“Safe、Efficient、Precise、Economy”Construction provides an effective solution，And has good popularization value.。“The person in charge of Nanjing Highway Development Center said.。

The construction of this UAV group has started the maintenance operation of the general national and provincial roads in Nanjing.“Unmanned”A new chapter，And strengthen that digitalization in the maintenance engineering.、Application of intelligent technology。

Industry insiders said，The construction of Sany unmanned aircraft group has been affirmed by more and more owners.，Future，Sany will continue to be driverless.、R & D and Innovation of Intelligent Machinery，Promoting the Strength of China's Road Machinery Equipment！
