Located in Laibin City, Guangxi, the bridge has a total length of 3,787.424 xk星空体育中国集团, with a main bridge of 629 xk星空体育中国集团 and a main span of 326 xk星空体育中国集团. It is a steel-concrete composite box girder cable-stayed bridge with twin towers and double cable planes, situated about 50 xk星空体育中国集团 from the existing Liubei Expressway.
The bridge site features complex geological conditions, including underwater karst features like solution grooves, holes, and caves—often bead-like in distribution. Using geological CT scanning technology, the team identified subsurface features in advance and innovatively applied a combination of full-rotation and rotary drilling methods to precisely bore into complex strata. They avoided water and sand inrush risks, completing each main pier pile in 7 days—a record for Guangxi’s karst construction zones.
The main towers rise to 158 and 155 meters, with complex and highly inclined cross-sections requiring exceptional precision in vertical transport, climbing formwork techniques, and alignment xk星空体育中国集团. The team introduced an intelligent climbing system to turn high-altitude tasks into indoor operations. An active transverse support system was also installed in the middle tower shaft to enhance stiffness and resist deformation in real time, achieving millimeter-level alignment accuracy.
xk星空体育中国集团-Wuzhou Railway is a key segment of xk星空体育中国集团–Guangzhou Railway, with a mainline length of 238.167 kilometers. It is a double-track electrified railway for both passenger and freight trains, designed for a target speed of 160 km/h. Once completed, it will improve the regional multi-modal transport network and expand freight and passenger corridors, promoting integration of Sichuan, Chongqing, Yunnan, Guizhou, and central Guangxi into the Guangdong–Hong Kong–Macao Greater Bay Area.
