CCTV Focus: Sany drone fleet leads a new chapter in intelligent road construction in Anhui
Sany Road Machine Sany Group July 24, 2024 19:31
Recently, CCTV News Channel "News Live Room" broadcast "Unmanned Paving Machines for Highway Construction", reporting on the innovative practices of Sany Group in the field of road construction in Anhui Province. Anhui, located in central China, is ushering in an intelligent revolution in its high-grade highway construction - Sany Group's drone swarm construction technology.
Since the end of April, this cutting-edge technology has shone in the first phase of the Anhui Xuanjing Expressway. At present, the SANY drone swarm has completed the construction of the middle surface layer of the two bidding sections of the project 01 and 03. The cumulative construction mileage has reached 80 kilometers. It is expected to fully enter the upper layer construction in early August.
During the three-month continuous construction process, the high efficiency and good quality of the unmanned spreader press group were fully demonstrated. The daily construction mileage was up to 1.8 kilometers. Through comparative experiments, the construction flatness was better than that of manual work, which won customers highly recognized.
The unmanned asphalt construction of the Xuanjing Expressway has three outstanding features: complete delivery, the most comprehensive technology application, and unmanned application across the entire line.
Achieve full delivery.
The UAV swarm application for the 03 standard of Xuanjing Expressway has been completely separated from SANY R&D personnel, and is operated completely independently by the technical personnel of Anhui Liju Group.
This is another major milestone since Sany delivered the country's first set of National IV intelligent spreader press equipment to Liju Group in November 2023, proving that Sany's unmanned spreader press group can no longer be operated only by R&D personnel. Instead of operating "precision instruments", they become products that can be delivered to customers for independent use.
The most comprehensive application of technology
In addition to applying standard unmanned driving technology, the fleet in Section 01 and Section 03 of the Xuanjing Expressway is also equipped with Sany’s latest research and development of paver assisted driving, automatic screed expansion and contraction, roller fusion welting, and 360-degree automatic driving. A series of stand-alone intelligent systems such as safety systems further reduce the number of auxiliary workers on site and improve operational safety and quality.
Unmanned application across the board
The first phase of the Xuanjing Expressway is divided into three tender sections, and a group of unmanned paving machines are used on the entire line to perform paving and rolling operations on asphalt pavement. Bid sections 01 and 03 both use SANY unmanned pressure spreading equipment.
This time, the Xuanjing Expressway has fully applied unmanned pressure spreading technology in all bidding sections for normal construction. It is not only a leader in the country, but also marks that through the unremitting efforts of colleagues in the past few years, unmanned pressure spreading technology is no longer just It exists as a "gimmick" in various observation meetings and demonstrations, and has begun to truly move towards industry applications.
In the future, Sany's unmanned spreader press fleet will continue to shine in major high-speed construction sites, leading the intelligent revolution in the field of road construction with its cutting-edge unmanned technology, excellent spreader efficiency and precise control capabilities. It will become a beautiful landscape in the construction of future transportation infrastructure.
China is too good at infrastructure. They've done like a century's worth of work in a decade.
It really is incredible. I wish I had visited the country a decade or two ago so I could visit again and see how much things have changed there. Entire cities of millions of people and huge mass transit systems that didn't even exist back then would just be mind blowing to be able to compare and contrast.
My city's government in the last two decades has barely managed to get a single tram line working(and it only goes to half of the places they initially planned), and has demolished pretty much all of the low income housing. Only "productive" area around here has been suburbs.
