Stiff composite pile sinking construction control method
The invention belongs to the technical field of stiff composite piles, discloses a pile sinking construction control method for a stiff composite pile, and aims to solve the problem that the stiff composite pile cannot be guided to construct according to stratum conditions due to less application of the stiff composite pile in some stratums. The method comprises the following steps: (1) high-strain pile testing; (2) according to the data obtained by the high-strain test pile, determining the segment distance; and (3) guiding pile sinking on a construction site according to the determined data of the segment distance. According to the method, instructive construction can be conducted according to different stratum conditions, so that the common construction problems such as pile body tension fracture, pile head damage, hammering eccentricity and pile body inclination in the pile planting process are prevented, then the pile forming efficiency is improved, and the pile forming period is shortened.
本发明属于劲性复合桩技术领域，公开了一种劲性复合桩沉桩施工控制方法，为了解决劲性复合桩在一些地层由于应用较少导致无法根据地层条件指导施工的问题。本发明包括(1)高应变试桩的工序；(2)依据高应变试桩获取到的数据来确定分段落距的工序；(3)依据确定的分段落距的数据来指导施工现场沉桩。本发明能够针对不同地层条件进行指导性施工，以防止出现植桩过程中出现桩身拉裂、桩头破损、锤击偏心、桩身倾斜等常见施工问题，进而提高成桩效率，降低成桩周期。
