SHANGHAI, July 10,
2024 /CNW/ -- On June 30,
2024, seven years after the Hong Kong-Zhuhai-Macao Bridge
opened to traffic, China's Pearl
River Delta celebrated another momentous milestone - the
Shenzhen-Zhongshan Link officially opened to trial operations. The
link, connecting the bustling Shenzhen City and Zhongshan City, integrates
bridges, man-made islands, tunnels, and underwater passages with a
total length of 24 kilometers and a two-way eight-lane.
While the completion of the Link is certainly exciting, the
super project has been known as one of the most challenging
sea-crossing projects in the world due to its geographical location
and technical difficulties. Behind the project, SANY, as one of the
contributors, plays a pivotal role.
Engineering Marvels: SANY's Role in Sea-Crossing
Projects
In July 2019, multiple SANY
crawler cranes were lowering the first steel suspension box of the
Lingdingyang Bridge, a critical component of the Link. With a
height of 14.5 meters and an outer diameter of 41.2 meters, the
suspension box weighs nearly 1,800 tons, more than the combined
weight of seven Airbus A380s. The suspension box, which is an
important anti-collision measure, provides a strong security
guarantee for the bridge. After 10 hours of continuous work, SANY
cranes lowered the box accurately into place.
In March 2020, the project entered
its key and most difficult phase – pouring over 5,098 cubic meters
of concrete in a single operation, equivalent to four standard
swimming pools. The high temperature and strong sea wind required a
fast and continuous casting, otherwise, the concrete would set
unevenly, leading to cracks. To ensure smooth pouring, SANY
dispatched service engineers to the site. Consulting with the
technical personnel, together they made a careful plan for the
pouring sequence and quality assurance. Ultimately, multiple
48-meter SANY pump trucks completed the casting work in 72 hours of
continuous work, nearly 10% shorter than the scheme time, setting a
new record for offshore construction. Such outstanding performance
underscores SANY's strong R&D capability and leading
manufacturing standards, which enable the equipment to maintain a
high degree of stability and reliability even in complex
engineering demands and harsh working environments.
Ushering in a new era: a 30-minute life circle
With the Link opening to traffic, the journey time from
Shenzhen to Zhongshan has been
reduced from 2 hours to 30 minutes, effectively integrating the two
cities into a single, accessible living area where daily commutes
and activities can be managed within a 30-minute travel radius. The
completion of the Link not only largely improved the living quality
of local people, but also injected new vitality into the economic
boom of the Pearl River Delta.
From the first desert railway to the world's largest-span
suspension bridge, SANY has been creating engineering miracles
worldwide. In the future, SANY will be committed to the mission of
"Quality Changes the World" and contribute to building a better
world for mankind with continuous innovation.
