Don't be afraid of "roasting"!The ground is more than 100 ° C to pave the way to use "drone"

Guangdong Maozhan high -speed reconstruction and expansion construction introduced the drone crushing machine group for the first time in the construction

Yangcheng Evening News reporter Wang Danyang, correspondent Shen Gao, Zhang Lishan, and Lin Lichuang reported: summer is inflamed, the ground is "like fire". On July 27th, Guangdong Maozhan high -speed reconstruction and expansion of the pavement construction site. At a pavement with a temperature of more than 100 ° C, a large paving machine is spreading the hot asphalt on the road. Order crushing flat.

The difference is that there is no one in the seven machine cab.

Chen Zhijiang, director of the Maozhan high -speed reconstruction and expansion project, introduced that with the "smart brain" composed of high -precision Beidou positioning, inertial navigation and obstacles recognition system, Maozhan high -speed transformation and expansion Unmanned roller group. Construction workers only need to set the crushing trajectory and speed of the construction section in advance. The driverless roadside machine will automatically control the pavement and crushing equipment to complete the established driving and steering.

"The traditional pavement crushing team generally needs 18 people. After the introduction of the drone group, only 5-8 auxiliary coordinated personnel need to be retained at the scene." Chen Zhijiang said, especially in the temperature environment of 30-40 ° C in the summer, crushing operations The temperature of the asphalt pavement is as high as 100 ° C. The use of new technologies not only reduces high -temperature operators, but also reduces the safety risks of human -computer interaction.

Relying on Beidou's high -precision positioning, the "drone" can also control the accuracy of the construction trajectory to 2 cm, so that the pavement pavement can be crushed more evenly, compact and flat. In addition, the "drone group" also has remote wake -up and dormant functions, which can automatically warn, stop emergency parking, automatic obstacles, and continuously construct all -weather construction.

The Maozhan Expressway was renovated and expanded by 108.59 kilometers. It was renewed and expanded according to the two -way 8 -lane highway standard. The design speed was 120 kilometers per hour. Among them, the Guanzhu to Forest House section is planned to be opened to traffic in 2022; the forest house to Gaoyang section is planned to be opened to traffic in 2023 to promote the radiation role of connecting the connecting connecting between the western Guangdong and the Pearl River Delta and the Guangdong -Hong Kong -Macao Greater Bay Area.
