Collapsible loess foundation treatment method
The invention relates to a collapsible loess foundation treatment method, which belongs to the technical field of foundation treatment. The method comprises the following steps: S1, leveling a construction site, carrying out fixed point marking and determining a construction position; S2, carrying out earth excavation to form a foundation pit, and carrying out sloping treatment; S3, carrying out step excavation on the slope to form steps; S4, installing a connecting mechanism on the step, wherein the connecting mechanism comprises a base arranged on the step, a waterproof plate arranged on the base and a driving assembly arranged in the base, an inserting pipe is installed on the waterproof plate, a positioning pipe is arranged in the inserting pipe, one end of the positioning pipe penetrates through the inserting pipe, and the other end of the positioning pipe penetrates through the waterproof plate and extends into the backfill earthwork; S5, treating the inner bottom face of the foundation pit; and S6, backfilling the earthwork in a layered mode, and carrying out tamping treatment through a tamping machine, wherein the height of each layer of backfilled earthwork is consistent with the height of the kicking face of the step on the same layer. The method has the effect of improving the combination effect between the unexcavated area and the fill.
本申请涉及一种湿陷性黄土地基处理方法，属于地基处理的技术领域，其包括以下步骤：S1、平整施工场地，定点划线并确定施工位置；S2、土方开挖形成基坑，并进行放坡处理；S3、对斜坡进行台阶开挖形成踏步；S4、在踏步上安装连接机构，连接机构包括设置于踏步上的底座、设置于底座上的防水板以及设置于底座内的驱动组件，防水板上安装有插接管，插接管内设置有定位管，定位管一端穿设于插接管内，定位管另一端穿过防水板并延伸至回填土方内；S5、对基坑内底面进行处理；S6、分层回填土方，利用夯实机械进行夯实处理，每层回填土方的高度与同层踏步的踢面高度一致。本申请具有提高未开挖区域与填方之间的结合效果的效果。
