Plain soil compaction pile construction method
The invention provides a plain soil compaction pile construction method. The plain soil compaction pile construction method comprises the following steps that S1, pile hole positioning is conducted, specifically, the position of each plain soil compaction pile is measured at the plane position and marked; S2, hole forming is conducted, specifically, a static pile driver is in place according to the marked positions, the center of the static pile driver is perpendicularly aligned with the hole mounting position mark to complete hole forming, and the diameter of formed holes is 510-610mm; and S3, the holes are filled with filler, specifically, the bottoms in the pile holes are tamped, 0.2-0.25m< 3 > of filler is backfilled each time, next backfilling is conducted after tamping, a soil layer with the thickness being 0.4-0.6m is reserved above a foundation surface, and after construction is completed, excavation or layered tamping of surface layer compaction is conducted. According to the plain soil compaction pile construction method, the pile holes of the specific specification are filled with the plain soil filler and tamped, thus the foundation strength can be improved, and foundation soil collapsibility is eliminated; and meanwhile, the plain soil compaction pile construction method has the advantages that construction is easy, the construction period is short, the quality is easy to control, and the construction cost is low.
本发明提供一种素土挤密桩施工方法，包括以下步骤：S1，桩孔定位，在平面位置测量出每个素土挤密桩的位置并做标示；S2，成孔，静压桩机按照标示位置就位，其中心垂直对准装孔位置标示完成成孔，成孔直径为510‑610mm；S3，孔内填料，夯实桩孔内底部，每次回填0.2‑0.25m3填料并夯实后再进行下一次回填，基础面以上预留0.4‑0.6m厚的土层，待施工结束后，将表层挤松的挖除或分层夯实；本发明中的素土挤密桩施工方法通过向特定规格的桩孔内部填充素土填料并夯实能够提高地基强度和消除地基土湿陷性，同时该方法具有施工简单、工期短、质量易控制、工程造价低等优点。
