Method for eliminating soil squeezing effect of pile foundations through flexible energy absorption band
The invention relates to a method for eliminating a soil squeezing effect of pile foundations through a flexible energy absorption band. The method aims to solve the problems of low construction efficiency and the narrow application range of existing methods for eliminating the soil squeezing effect. The method for eliminating the soil squeezing effect of the pile foundations through the flexibleenergy absorption band includes the following steps that a pile foundation construction area is arranged and an adjacent building area which needs to be protected is divided; the placement position ofthe flexible energy absorption band is arranged at the position, 0.3-0.5 time the distance between the pile foundation construction area and the adjacent building area away from the adjacent buildingarea, in the pile foundation construction area; the positions of both ends of the flexible energy absorption band are determined according to the pile foundation construction area; flexible micro-pile positions are arranged at the positions of the arranged flexible energy absorption band, and the diameter and length of each flexible micro-pile are preset; holes are drilled at the arranged positions of the flexible micro-piles; the holes of the flexible micro-piles are filled with high-consistency flexible materials; construction of the pile foundations in the pile foundation construction areais performed; and after the completion of the pile foundation construction, the high-consistency flexible materials in the holes of the flexible micro-piles are replaced with portland cement.
本发明涉及一种通过柔性吸能带消除桩基挤土效应的方法，以解决现有消除挤土效应的方法存在施工效率低、适用范围窄的问题。该通过柔性吸能带消除桩基挤土效应的方法，包括以下步骤；设定桩基施工区域并划分需保护的临近建筑物区域；在桩基施工区域距临近建筑物区域的0.3‑0.5倍桩基施工区域和临近建筑物区域之间距离处设置柔性吸能带的布置位置；根据桩基施工区域确定柔性吸能带两端的位置；在设定的柔性吸能带位置布置柔性微型桩桩位，并预设柔性微型桩的直径及长度；对设定的柔性微型桩桩位钻孔；在柔性微型桩桩孔内填充高稠度柔性材料；在桩基施工区域内进行桩基的施工；桩基施工完毕后，将柔性微型桩桩孔内高稠度柔性材料替换成硅酸盐水泥。
