Quality control method for underwater pouring concrete pile body of cast-in-place pile
The invention relates to a technology for underwater pouring of a concrete pile into a cast-in-place pile, in particular to a quality control method for an underwater pouring concrete pile body of the cast-in-place pile. The quality problems that the quality of a pile body is difficult to guarantee and slag inclusion, faults, hole collapse and the like are easily generated in the concrete pouring process of the wet operation pore-forming cast-in-place pile are solved. The first operation handle and the second operation handle are adjusted until the first sampling opening and the second sampling opening are completely overlapped, concrete at the sampling position enters the second pipe fitting, the first operation handle and the second operation handle are adjusted again to completely stagger the first sampling opening and the second sampling opening, the tool is lifted upwards in the vertical direction, and finally a sample in the second pipe fitting is taken out by lifting the rod piece. Whether the quality meets the requirement or not is judged by analyzing the quality of the concrete; and if the quality problem occurs, the guide pipe is inserted into the position lower than the position with the quality problem again, then concrete is poured, and the concrete with the quality problem can be ejected out of the pile hole.
本发明涉及灌注桩水下浇筑混凝土桩的技术,具体为一种灌注桩水下浇筑混凝土桩身质量控制方法。解决湿作业成孔灌注桩浇筑混凝土过程中桩身质量难以保证,容易产生夹渣、断层、塌孔等质量问题。通过调整操作柄一和操作柄二至取样口一和取样口二完全重合,取样处混凝土进入管件二内部,再次调整操作柄一和操作柄二将取样口一和取样口二完全错开,沿竖直方向上提工具,最后通过上提杆件将管件二内部的样品取出,通过对该混凝土的质量分析判断质量是否符合要求;若出现质量问题,将导管重新插入至低于有质量问题的位置,接着浇筑混凝土即可将有质量问题的混凝土顶出桩孔。
