△ 3DApplication of Millimeter Variable Milling Construction Technology in Reconstruction and Expansion Project of Beijing-Kunming Expressway
Topcon 3D mmGPSSpreading/Milling control system，Is based on 3DDigital construction design model，Realize the automation of paving and milling operation、Simplify、High-precision mechanical automatic construction，Is the world's leading professional road construction for the field of 3DDigital construction process，Compared with the traditional paving and milling proces，Has the advantages of no need of repeated piling and paying-off、Erection of inverted beam and manual marking of thickness, etc.，The construction site is cleaner and more orderly.，Day and night construction can ensure millimeter-level construction control accuracy，It can effectively control the smoothness of pavement construction、Advantages of key quality indicators such as cross slope，But also improve that operation efficiency and the construction quality.、Reduce the safety risk of man-machine cross operation, etc.。At the present stage, the construction and expansion of expressways in many provinces of the country、New construction, reconstruction and expansion of airport runway、It has been widely used and verified in the new construction and expansion of the test yard and other high-level construction projects.。
Among them, Xi'an Outer Ring Expressway and Ring Expressway in Shaanxi Province、Reconstruction and expansion of Beijing-Kunming Expressway、GIt has been applied on a large scale and for a long time in high-speed projects such as the reconstruction and expansion of 65 Qutai Expressway.，While substantially saving manpower input,，The construction efficiency and quality have been significantly improved.，Especially the high-speed reconstruction and expansion to solve the old and new pavement overlap.、And that smoothness of the road surface is improve、Thickness uniformity、The accuracy of cross slope control has achieved remarkable improvement.。
