SEVERAL PROBLEMS IN THE APPLICATION OF PRE-STRESSED CONCRETE TUBULAR PILE |
|
摘要 预应力管桩具有单桩承载力高、适用范围广、施工速度快等优势,预应力管桩承载力会随时间的增长而提高。桩锤的选择要综合考虑各方面因素,桩身垂直度偏差应不超过1%。每根桩宜连续施打到底,并采取措施减少挤土现象,以保证桩的承载力和防止产生过大的桩身位移。 |

Abstract:
There are a lot of advantages in pre-stressed concrete tubular pile such as higher bearing capacity,better adaptability and speedy construction progress.The longer the pile is being at work, the higher bearing capacity it will have.When selecting pile driver various factors should be considered.The verticality deviation should not exceed 1%.Individual pile should be kept driving continuously while earth squeezing should be avoided to ensure bearing capacity and minimized lateral displacement.
