"Black technology" helps! Sany drone swarm went to Nanjing!

The sun is red, and the construction is at the right time. Sany "Black Technology" unmanned paving machine group went to Nanjing to help the Lishui section of the S246 Ninglang Line of the Nanjing Ordinary National and Provincial Highway Maintenance Project.

On the construction site, there are almost no operators. The unmanned paver group composed of 1 SAP130C-8 paver, 2 SPR300C-8 rubber tyre rollers and 3 STR130C-8 tandem rollers performed their duties and jointly carried out asphalt paving, initial pressure, repressing, final pressure and other operations. It is understood that this is alsodroneThe first application of group construction technology in the maintenance project of ordinary national and provincial highways in Nanjing.

According to the on-site staff, the operation content of the Sany unmanned paving machine group is Jiangsu 246 Provincial Highway (Ninglang Line) K74+000-K75+000 section, with a total length of 1km, a construction width of 8.2m, the construction content is the upper layer of asphalt, the thickness of asphalt loosening is 4.8cm, the construction section is located at the intersection of the longitudinal slope of the line and the curve, the longitudinal slope of the line is about 7%, the radius of the curve is about 700m, and the construction adopts the "1 stall + 2 double + 2 glue + 1 double" machine group configuration.

246 Provincial Highway (Ninglang Line) starts from Nanjing Ring Road, goes south through Jiangning District, Lishui Development Zone, Dongping, Yongyang, Jingqiao, Gaochun Paint Bridge, leads to Langxi Jingnei in Anhui Province, so it is also known as Ninglang Highway, with a total length of about 92 kilometers, including 32 kilometers of Jiangning section, 45 kilometers of Lishui section and 15 kilometers of Gaochun section, which was completed and opened to traffic in 2011, which is the longest trunk road in the history of Nanjing highway construction, and also the first trunk road completed in Nanjing during the "Twelfth Five-Year Plan" period.

The unmanned paving operation is divided into two times, 300m test section + 700m formal construction section, during the construction process, the Provincial Department of Communications, Zhenjiang Road and Bridge and other leaders and experts at all levels have come to the site to observe and exchange, and the operation effect of the on-site machine group has been unanimously recognized and praised by on-site experts. After the completion of construction, the pass rate of key indicators such as flatness, compaction, water seepage rate, thickness and other key indicators of the unmanned paving operation section reached 100%, and the project quality was good.

"Sany unmanned paving machine group operation in terms of quality has met the relevant standards and specifications, saved labor costs in terms of cost, reduced the probability of risk occurrence in safety, and provided an effective solution for the "safe, efficient, accurate and economical" construction of the road, which has good promotion value. The person in charge of the Nanjing Highway Development Center said.

The construction of the UAV group has opened a new chapter in the "unmanned" maintenance operation of ordinary national and provincial roads in Nanjing, and strengthened the application of digital and intelligent technology in the maintenance project.

Industry insiders said that the construction of Sany unmanned aircraft group has been affirmed by more and more owners, and in the future, Sany will continue to carry out the research and development and innovation of unmanned and intelligent machinery to promote the improvement of China's road machine equipment strength!
