Sany unmanned intelligent paving the way, Luyong Expressway to help the development of Chengdu-Chongqing

Luyong Expressway is an important inter-provincial passage in the layout planning of the expressway network of the Chengdu-Chongqing Economic Circle, and it is also the most convenient expressway connecting Luzhou, Sichuan and Yongchuan, Chongqing, with only more than 40 minutes by car after the opening of the two places. Luzhou starts from G76 Xiarong Expressway in Jianshe Village, Niutan Town, Luxian County, and ends at the junction of Sichuan and Chongqing in Xialin Village, Bilu Town, and connects to Chongqing Yonglu Expressway. The total length of the route is 42.307 kilometers, the design speed is 100 kilometers per hour, and there are 7 interchanges on the whole line.

The completion of the Luyong Expressway will help Luzhou build a regional comprehensive transportation hub, and on the basis of meeting the needs of the masses in the two places for travel and trade exchanges, it can also effectively promote the integrated development of the Chengdu-Chongqing Economic Circle, and lay a solid transportation foundation for Luzhou to implement the characteristic development strategy of "one body and two wings" and build a regional central city in the new era.

During the May Day period, the road section in Luzhou, Sichuan Province is undergoing the final paving work in an intense and orderly manner. During the laying of this project, the construction party used a number of unmanned machines and equipment from Sany.The unmanned paving machine group jointly developed by Sichuan Road and Bridge and Sany Heavy Industry "smart" paves the way to help the construction of Luyong Expressway; This set of equipment uses 7-layer process and full machinery to efficiently and accurately compact the pavement - the labor is reduced by 70% and the efficiency is increased by 25%, which opens up a new situation of pavement automation construction and takes a solid step for intelligent construction.

Pan Wenchuan, chief engineer of the ZCB1-LM bid section project of Luyong Expressway, told reporters: "According to the alignment of the current route, we input the data of the alignment of the route into the control system of the paver and roller, and during the construction process, the paver and roller pave and roll according to the input data, achieving the purpose of unmanned." ”

It is understood that the unmanned pressure detection system is jointly developed by Sichuan Road and Bridge and Sany Heavy Industry, with the help of the digital construction cloud platform can complete all the construction operations by themselves, the whole process is fully automatic and fully mechanized, and the efficiency has been effectively improved.

Pan Wenchuan introduced: "The whole process is fully automated, fully mechanical, labor is reduced by 70%, and the efficiency is increased by 25%, which effectively solves the safety, efficiency and quality problems of personnel and equipment in the construction process, and achieves construction visualization, construction controllability, construction digital traceability, stronger automation experience, higher degree of intelligence, opens up a new situation of road automation construction, and takes a solid step towards intelligent construction." ”
