With the accelerated progress of urbanisation, high-rise housing on the ground facilitates the lives of the public. But in the invisible underground, is another scene, underground tunnels, tunnels, 

integrated tube corridors and other underground infrastructure construction and operation scale continues to expand, tunnel collapse, water, deformation, cracking and other safety hazards also 

come.

To ensure the safety of tunnel construction and operation is to protect the city's important infrastructure construction of the ‘lifeline’. Recently, a ‘recluse’ from the ‘robot hardcore 

equipment’ again for Guangdong ‘smart’ to add bricks and mortar. It is reported that this is the Guangdong Construction Engineering Holdings belongs to the Guangdong Provincial

 Academy of Building Research Group Co., Ltd. after three years of independent research and development of the ‘all-terrain tunnel inspection robot’ hardcore equipment, has been 

successfully applied to the Guangzhou Metro, Foshan Metro, Zhongshan Central City Tunnel, Zhuhai Hengqin Comprehensive Pipeline Corridor, and other projects for the city 

underground! Safe operation of infrastructure escort.

The reporter understands that the all-terrain tunnel inspection robot integrates three-dimensional laser scanning, high-precision line array industrial camera, inertial guidance system 

and other cutting-edge technologies, and can obtain panoramic high-definition images, sign information, appearance of disease, section size, etc. in real time, to meet the needs of 

the tunnel appearance inspection, section measurement and deformation monitoring. Acquisition speed up to 15 km / h, section scanning speed up to 200 revolutions / sec, 

three-dimensional scanning speed of more than a million points / sec, crack identification accuracy of 0.2 mm, supporting the development of rail-type mobile trolleys, vehicle 

platforms, automatic marching control system, can be achieved in the underground tunnels, vehicular tunnels, integrated corridors and other scenarios of automation, 

intelligent inspection operations.

Since this year, Guangdong Province to transport the construction of a strong pilot work as a traction, accelerate the full implementation of the five-year action plan, 

in the ‘high-quality development of transport infrastructure’ to carry out a comprehensive pilot. In April this year, the 2024 World Tunnel Congress opened in 

Shenzhen. Guangdong is the ‘front-runner’ in the construction of the national transport network, a tunnel project through the mountains and the sea, becoming 

an ‘accelerator’ of the city's high-quality development, a breakthrough in technological innovation in difficult tunnels, becoming a shining industrial manufacturing in China. 

‘A technological breakthrough in difficult tunnelling technology has become a shining business card of China's industrial manufacturing. In the future, as Guangdong ‘smart’ 

manufacturing on the development of new productivity empowerment gradually appeared, science and technology innovation to shape the development of new momentum 

and new advantages of the role of the new advantages will also be more and more prominent.
