Reconstruction construction method and structure for basement foundation
The invention provides a reconstruction construction method and structure for a basement foundation. The reconstruction construction method for the basement foundation comprises the steps that surveyand setting out are carried out; pile positions are confirmed; holes are formed in a roof, a middle floor and a bottom plate of the basement according to the pile positions; a steel pile casing is made and is buried according to the floor height; a pile machine is placed in place, and direct cycle hole forming is carried out; hole cleaning of the first time is carried out; the hole forming qualityis detected; a reinforcement cage is placed down, and a guide pipe is placed; hole cleaning of the second time is carried out; concrete is poured; and concrete maintenance is carried out. In the reconstruction construction method and structure for the basement foundation, the basement foundation is reconstructed through a high pile casing cast-in-place pile process, underground water sudden surging can be effectively avoided, the construction risk is greatly reduced, the pile forming quality is better, the construction period is shorter, and the cost is lower.
本申请提供了一种地下室基础改造施工方法及其结构，其中，所述地下室基础改造施工方法包括：测量放样，确定桩位；根据桩位在地下室顶板、中楼板和底板上分别开洞；制作钢护筒，并根据楼层高度埋设所述钢护筒；桩机就位，并进行正循环成孔；进行第一次清孔；检测成孔质量；下钢筋笼，放导管；进行第二次清孔；灌注混凝土；混凝土养护。在本申请提供的地下室基础改造施工方法及其结构中，采用高护筒灌注桩工艺进行地下室基础改造，不但能够有效地防止地下水突涌，大大降低施工风险，而且成桩质量更好，工期更短，费用更低。
