Smart Bridge Tower Construction Uses New Machine

A 400-ton tower climbing machine is being used to construct the ultra-high bridge towers of the Hong Kong-Zhuhai-Macao Bridge. This technology aims to address the limitations of traditional manual construction methods in complex three-dimensional structures. The innovation seeks to replace labor-intensive processes with automated, high-precision assembly. The process involves creating mesh panels on assembly lines where bars are joined via welding points. Engineers noted that if connection stiffness is not achieved, there is a risk of materials falling from heights of 200 to 300 meters. Each steel mesh panel requires at least 1,600 weld points to ensure structural integrity. The construction process involves a mobile factory-like platform around the tower base. The concrete base tower grows at a stable rate of 1.2 meters per day with minimal staff. Engineering teams face challenges including high salinity, high humidity, strong winds, and frequent typhoons, with wind speeds reaching 37 meters per second. Wind speeds at the current construction stage have reached 37 meters per second. Strategic engineer Li Bazhou, who has 17 years of experience in bridge construction and intelligent equipment R&D, is overseeing the project. Engineer Li Bazhou has been working in bridge construction technology and intelligent equipment for 17 years, leading the development of this new system which aims to overcome challenges posed by high winds and difficult conditions on the Lingdingyang sea.
