April on earth，It's a good time for construction。In the near future，At the construction site of the asphalt surface course of the second bid project of Gansu Luqiao Anlin Pavement，Sany's unmanned compactor group is carrying out the paving and compaction of asphalt pavement in an orderly manner.，This is also the first time that the Sany Unmanned Pressing Machine Group has appeared in the highway pavement construction project in Gansu Province.。

The Sany Unmanned Pressing Machine Group, which helps the construction of Anlin Expressway Project, includes oneSAP130C-10 High-grade asphalt paver、TwoSPR300C-8 rubber-tired rollers and threeSTR130C-8 double drum roller，6 sets of unmanned spreading equipment in total，Successfully complete the paving of the asphalt pavement、Initial pressure、Repressing、Final pressure operation。

SANY Unmanned Pressing Machine Group PassedUnmanned driving technology、3DAutomatic paving technology、Intelligent compaction technology、Collaborative scheduling technology and visualization technologyAnd other intelligent technologies，Positioning and navigation by Beidou satellite，According to the preset paving speed、Running track、Rolling speed、Number of times of rolling、Overlapping width cooperative operation，The system adjusts the construction parameters in real time according to the site conditions.，While realizing the fine management and control of high-grade pavement construction，It also ensures the quality of road paving.。

The project responsible person said.，Select the unmanned spreading equipment of Sany Heavy Industry，YesBased on the trust of Sanyi Road Machine products，It is also based on the comprehensive consideration of using digital technology to improve the quality and efficiency of pavement construction.。The successful construction of the unmanned compactor group in Anlin Expressway Project，By the construction side and the owners of the praise.，Four Key Technologies Help Perfect Construction of Unmanned Compactor Group。

One、Convert the design route parameters into electronic map in advance，Complete digitalization of construction environment and construction tasks，The construction technology is realized.Digital modeling。

Two、Optimal path generated according to sophisticated algorithm、Real-time status and construction schedule of the fleet，The cluster is realized.Real-time dynamic cooperative scheduling。

Three、Automatic control algorithm via paver，High-precision tracking operation path，Collocation 3DPaving system，The paver is realizedAutomatic high-quality paving operation。

Four、Under high-precision orbit tracking and optimal path setting，Automatic control by program，Under the condition that safety is guaranteed，RealizedStandardized compaction operation。

Through the above whole process data collaboration，The operation precision of the unmanned aerial vehicle group is effectively controlled at 5cmWithin，It greatly improves the pavement smoothness and construction efficiency.。

Sany Unmanned Pressing Machine Group has made its debut in Shanghai since 2019.，Through continuous technological innovation，Intelligent obstacle avoidance has been achieved，Through standardized operations，The construction quality is good、High efficiency，Pavement evenness、The compactness fully meets the requirements of construction design standards.，And the pressure leakage possibly caused by manual operation is avoided.、Overpressure、Undervoltage、Problems such as speeding，It can achieve 24-hour uninterrupted operation while reducing labor.，YesSafe construction、Intelligent construction、And that construction efficiency is improve、Cost savingThe most direct manifestation of。

Intelligent construction technology is the frontier technology to promote the subversive change of production mode in transportation construction industry.。With artificial intelligence、The development of automatic driving and other technologies，Automation、Unmanned pavement construction has become a general trend.。This time, the Sany Unmanned Compactor Group successfully helped the intelligent construction of the asphalt pavement of the second bid project of Gansu Road and Bridge Anlin Pavement.，It is of great significance for the high-quality construction of pavement engineering in Gansu Province.。

At present，Sany unmanned intelligent aircraft group is“Fight for the whole country”，Its footprints cover 15 provinces in China.，Participated in the construction of Shenhai Expressway、Beijing-Taiwan Expressway、Nearly 30 national key projects such as Luyong Expressway have been highly recognized.。Future，Sany will continue the intellectualization of pavement construction.、Technological innovation in the field of electrification，Overcome difficulties、Update iteration，Leading the high-quality development of the industry，For China“Zhi”Make a contribution！
