套管咬合桩在南京软土地区的应用研究

A Study on the Drilling Lock-Joint Pile at Soft Soil in Nanjing

贝诺特(Benoto)灌注桩工法,即全套管咬合桩在国内部分地区应用已比较成熟,并且取得了良好的技术经济效果。但在南京软土地区,由于应用时间较短,施工工艺及相关的技术措施尚需进一步总结和完善。本文就此进行初步的研究和探讨。

Drilling lock-joint pile of full casing, i. e. Benoto cast-in-place pile method, is a kind of mature enclosure construction technology, and put into use many times at home, and meanwhile, actually it has the good effect of technology and economy. Owing to the fact that it is the first time to be constructed in the soft soil layers in Nanjing, its construction techniques and technical measures must be summarized and consummated. Thus this paper conducts research and discussion in the field.
