预应力管桩水平顶拉纠偏与加固技术研究

The pre-stressed pipe top-level pull correction and reinforcement technology research

针对预应力管桩在沉桩过程中遇到较厚的软土层,容易引起桩身倾斜的现状,阐述了预应力管桩在施工完成后发生倾斜偏位等质量问题时采用的水平顶拉纠偏与加固技术,指出该技术可以在最短工期内,用较少费用完成纠偏加固。

Aiming at the situation that pre-stres,sed pipe pile in the process, when the thick layer of soft, easily lead to the situation of tilt the pile. In this paper, elaborates the pre-stressed pipe in the construction took place after the completion of the tilt-bit quality, using pull-top level of technical correction and consolidation. It points out that the technology work in the shortest possible period, less the cost of correcting the correction and reinforcement.
