On December 16, 2020, the groundbreaking ceremony for the Jiangmen Huangmaohai Sea-Crossing Bridge project was held. Xuzhou YiOu drill pipes are once again paired with XCMG XR550 and XR580 rotary drilling rigs. Following river-crossing and sea-crossing projects such as the Changtai Yangtze River Bridge and the Zhanjiang Nansandao Bridge, they will once again contribute to the construction of a national super project.

　　The construction of the Huangmaohai Link Project will change the current situation of a single channel between the coastal areas of western Guangdong and the core area of the Greater Bay Area, enable the economic development of the Greater Bay Area to radiate to western Guangdong and coastal areas, and together with the Hong Kong-Zhuhai-Macao Bridge, Nansha Bridge, and Humen Bridge form a cluster of sea-crossing and river-crossing channels in the Greater Bay Area, accelerating the formation of a world-class transportation hub and building a new regional development pattern of “one core, one belt, one region”.
