Chongqi Yangtze River Rail-cum-Road Bridge
North main tower pile foundation construction for the Chongqi Yangtze River Rail-cum-Road Bridge, using large rotary drilling rigs and tremie pipe systems for deep-water pile engineering. Main pier pile depth exceeds 80m in complex geological conditions.
项目挑战
Super-large diameter pile foundation construction in deep water with complex geology, requiring overcoming cobble layers and highly weathered sandstone formations.
解决方案
Deployed multiple large rotary drilling rigs and tremie pipe systems, adopted staged drilling techniques with professional operation teams ensuring construction precision.
项目成果
Successfully completed all north main tower pile foundations, with single-pile drilling cycles reduced to 4-5 days, 100% pass rate, and excellent quality acceptance.
