On February 19, the E29 immersed tube of the Hong Kong-Zhuhai-Macao Bridge, a national key project, was precisely installed. The total length of the completed tunnel has reached 5,481 meters, with only 183 meters remaining before the full breakthrough of the bridge tunnel. The two "Tiantong" mixing ships and five sets of concrete mixing plants specially customized by Shantui Jianyou for key projects, with their reasonable and reliable design, stable product performance, and strong production continuity, have withstood the severe test of a tight schedule, high standards, and strict requirements, making positive contributions to fully supporting the construction of the Hong Kong-Zhuhai-Macao Bridge.

For many years, Shantui Jianyou has relied on technological innovation to solve technical difficulties, producing high-value-added and high-tech products to relieve users of worries. Among them, the subsea deep soft foundation treatment mixing equipment is special equipment for slurry preparation and pressure injection in subsea deep soft foundation treatment. During construction, the original subsea materials are directly used, avoiding excavation construction, reducing environmental pollution to the surrounding sea area during construction, maintaining the original state of the construction sea area, and at the same time greatly reducing the post-construction settlement of the reinforced foundation.

It is reported that the Hong Kong-Zhuhai-Macao Bridge, called one of the "Seven Wonders of the Modern World" by the British newspaper The Guardian, is China's first world-class sea-crossing bridge connecting Hong Kong, Zhuhai, and Macao, with a total length of 55 kilometers. Since the construction unit entered the site in July 2012, construction has lasted more than four years, applying a series of new technologies, new materials, and new equipment, filling gaps in many fields, forming "Chinese standards" that are moving toward the world, and representing the highest embodiment of China's bridge-building technology.
