Layered construction method for vibro-replacement stone column in upper-hard and lower-soft stratum
The invention discloses a layered construction method for vibro-replacement gravel piles in an upper-hard and lower-soft stratum. The layered construction method comprises the following steps that soil layer distribution in a construction site is judged; selecting the model of the vibroflot and determining construction control indexes; setting the rotation frequency of the vibroflot as a rated rotation frequency for vibroflot pore-forming; cleaning the hole; the rotating frequency of the vibroflot is adjusted to the rotating frequency for the lowermost soil layer, and filler vibroflot compaction construction of the lowermost soil layer is started; judging whether a construction control index is met; the filler vibroflotation compaction construction of the next section of the lowermost soil layer is continued until the filler vibroflotation compaction construction of the lowermost soil layer is completed; the rotating frequency of the vibroflot is adjusted to the rotating frequency for the next soil layer, filler vibroflot compaction construction of the next soil layer is started, and whether the construction control index is met or not is judged; and construction is completed. The pile forming quality can be improved, meanwhile, energy can be saved, and the beneficial effects of being convenient and fast to operate, reliable in quality and the like are achieved.
本发明公开了一种上硬下软地层中振冲碎石桩的分层施工方法,包括以下步骤：判断施工场地内的土层分布；振冲器的选型及确定施工控制指标；将振冲器的转动频率设定为额定转动频率进行振冲造孔；清孔；将振冲器的转动频率调整到针对最下部土层的转动频率，开始最下部土层的填料振冲密实施工；判断是否满足施工控制指标；继续最下部土层下一段的填料振冲密实施工，直到完成最下部土层的填料振冲密实施工；将振冲器的转动频率调整到针对下一土层的转动频率，开始下一土层的填料振冲密实施工，判断是否满足施工控制指标；直至施工完毕。本发明能在提高成桩质量的同时还能节省能源，且具有操作便捷、质量可靠等优点。
