The invention discloses a foundation reinforcing method for constructional engineering. The foundation reinforcement method comprises a soil pile compaction method and a lime soil pile compaction method, and specifically comprises the following steps that S1, pile hole positioning is conducted, specifically, the deviation required by pile hole positioning is not larger than 5 cm, small wood piles or thick steel bars can be driven into soil by 20 cm, and after the small wood piles or thick steel bars are pulled out, a small amount of lime water is poured into holes. The method has the main characteristics that large excavation and large filling are not needed, the earthwork volume is small, the soil pile compaction method is different from vertical compaction methods such as tamping and rolling and belongs to a transverse compaction soil layer, when a casing pipe is driven into a stratum during construction, foundation soil around the casing pipe is subjected to a large horizontal compaction effect, the engineering physical property of the foundation soil within a certain range around the casing pipe is improved, the compactness is increased, the compressibility is reduced, and the collapsibility is completely or partially eliminated.
本发明公开了地基加固方法包括土桩挤密法和灰土桩挤密法，具体包括以下步骤：S1：桩孔定位：桩孔定位要求偏差不超过5cm，可用小木桩或粗钢筋打入土中20cm，拔出后在孔内浇少许石灰水即可。本发明的主要特点是不需大挖大填，土方量少，土桩挤密法与夯实、碾压等竖向加密方法不同，属于横向加密土层，施工中当套管打入地层时，管周地基土受到了较大的水平向挤密作用，使管周围一定范围内的地基土的工程物理性质得到改善，其密实度增加、压缩性降低、湿陷性全部或部分消除。
