Wirtgen 3D Milling Technology Lays the Foundation for the Renovation of Shanghai International Circuit

October 22, 2024

Shanghai International Circuit,Since its unveiling in 2004,It has witnessed the rapid development of China's motor sports.,It has become China's Formula One with great international influence.(F1)Racing track。Time and tide wait for no man,The season is like a stream。After 20 years of trials and hardships,The aging and damage of the asphalt surface of the racetrack has become an urgent problem to be solved.。

For this reason,A race aimed at restoring the youth of the track、The renovation project to improve the overall competition quality of the track was officially launched in July 2024.。

The renovation project is on a grand scale.,Covering the main track of the Shanghai International Circuit、Short track、Working lanes and some buffer zones and other areas,It is also the first comprehensive overhaul of the FIA certified first-class track in China since the completion of the race track 20 years ago.。

The main track of Shanghai International Circuit is 5..Four kilometers,The change of slope directly affects the speed strategy of the car.,16 corners、Variable longitudinal slope with maximum drop of 12m and maximum inclined surface of 12%Variable transverse slope,And the strict design standards of the track and the established construction period,It is a severe test for the construction side.。

In view of the complex and changeable track structure and particularity,Therefore, it is the first process of construction.,Milling and planing operation, which lays the foundation of paving flatness, becomes the key to determine the quality and construction progress of the project.。To this end, the construction side introduced the external connection 3 of Wittgen milling technology.D Construction technology of digital control technology,Lay a solid foundation for high flatness。

Pass through Wittgen 3D Digitally controlled milling process,The overall flatness of the track has been restored.,The subsequent paving steps can meet the design requirements of the smoothness of the track as long as the ordinary Paver passes through the conventional asphalt paving operation.,It greatly reduces the difficulty of subsequent construction organization for the construction party.,The risk of the whole construction progress and quality control is reduced.。

Stable, efficient and rapid progress

Different from the previous track trimming,It only needs the Wirtgen Milling Machine to cut the local position accurately to complete the rapid repair.(Click on the link to learn about past applications),This is a thorough repair of the entire main track.,Therefore, the construction party has invested three Wittgen large Milling Machines. W 205i Pair up to 5.The old surface layer of the whole main track of 4 kilometers is removed.。

During construction,Three Wittgen Milling Machines are firing on all cylinders.,It took only about one week to complete a large area of milling work.,Time was gained for the subsequent construction steps.。


Digital-driven Lean Quality Assurance

It is worth mentioning that,Wirtgen's large milling machine is equipped with WIDRIVE Intelligent control system,Can be connected with various external 3D Easy connection of the control system,Through excellent equipment performance,Precise execution 3D Digital commands from the control system,Give full play to the advantages of lean construction of digital technology。

In the pre-construction preparation process,3D The control system performs modeling by scanning the milling construction data in advance through the instrument.,By mounting on the milling machine GNSS Global Positioning System,With Wittgen Level pro Plus Comparing the actual elevation data of the original pavement measured by the leveling sensor with the design data,The system passes the difference to the milling machine,The elevation accuracy can be controlled at the millimeter level in the milling process.。

In the milling process,3D The differential signal consists of 3D System Controller,Through CAN The bus is transmitted to the milling machine controller,Wittgen WIDRIVE Intelligent milling control system,Automatically based on the differential signal data,,Automatically adjust the milling depth in real time,Make sure that in any different location,Can be milled to the depth of the design plan,So as to achieve“High places are milled and planed thickly,The low place is shallow in milling and planing”Precise milling and leveling effect。

Compared to traditional milling operation,This is externally connected by 3.D The milling system guides Wittgen's milling process to complete the millimeter level of the track in a short time.“Print type”Milling effect,Minimize the dependence of construction quality on the operation level of the operator,Satisfy at the same timeF1 High standard requirements of the track,Save manpower、Equipment wear and tear and overhead。

Final,Pass through Wittgen W 205i The milled track surface achieves the high flatness required by the design.,Laying the foundation of flatness for the subsequent paving operation。September fourth,The Shanghai International Circuit has taken on a new look.。

During the renovation of the Shanghai International Circuit,The Wirtgen Group has once again proved its value as a professional partner in the construction of international racetracks.。The Wirtgen Group will continue to provide advanced construction equipment and solutions,To create engineering results that exceed expectations for customers。
