利用浮托力弥补打桩船吊装能力的不足

Application of Buoyancy to Remedy Inadequacy of Lifting Capacity of Piling Barge

针对混凝土大直径管桩沉桩施工时打桩船吊装能力存在不足的问题进行了分析,提出了利用管桩空腔排水产生的浮托力来弥补的措施。沉桩结果表明,这种方法是切实可行的,对类似工程的沉桩施工具有参考价值。

Based on the analysis of the inadequacy of the lifting capacity of piling barge in large-diameter prestressed concrete pipe pile driving construction, the measure of applying buoyancy generated by cavity drainage to remedy the inadequacy is put forward. The result of pile driving proves that the measure is feasible and may serve as a reference for pile driving construction of similar projects.
