Dynamic compaction replacement reinforcement method for foundation treatment
The invention discloses a dynamic compaction replacement reinforcement method for foundation treatment. The dynamic compaction replacement reinforcement method comprises the steps that early-stage engineering preparation is carried out; a reasonable dynamic compaction replacement method is designed according to the field geology and the surrounding environment; the foundation is preliminarily leveled, and multiple protection measures are additionally arranged; trial tamping and trial tamping effect detection are carried out; the ground elevation is measured; a tamping point is measured and placed; the site is leveled again, and full compaction construction is carried out; and dynamic compaction detection and acceptance are carried out. According to the dynamic compaction replacement reinforcement method for foundation treatment, standing simple equipment on a construction site is used, the construction process is simple, the applicable soil texture range is wide, high bearing capacity can be obtained, and the strength of a common foundation can be improved by 3-5 times; the deformation settlement amount is small, the compressibility can be reduced by 5-10 times, the construction period is short, raw materials and investment are saved, and the cost is reduced; compared with a precast pile reinforced foundation, the investment can be saved by 60%-70%; and compared with a sand pile, the investment can be saved by 50%-70%, accurate replacement of a target soft stratum can be achieved, a thick soft soil layer foundation is solidified, the strength of the foundation is improved, and the efficiency is higher.
本发明公开了一种地基处理强夯置换加固方法，包括：前期工程准备；根据现场地质及周边环境设计合理的强夯置换法；对地基进行初步平整以及添加多道防护措施；试夯以及试夯效果检测；地面标高测量；夯点测放；再次对场地平整，并进行满夯施工；强夯检测及验收。本发明使用工地常备简单设备，施工工艺简单，适用土质范围广，可取得较高的承载力，一般地基强度可提高3‑5倍；变形沉降量小，压缩性可降低5‑10倍，工期快，节省原材料和投资，降低费用；与预制桩加固地基相比可节省投资60％‑70％；与砂桩相比可节省投资50％‑70％，能达到对目标软弱地层的精确置换，使厚软土层地基固结，提高地基强度，且效率更高。
