Silt silty clay layer deep foundation pit base reinforcing treatment method
The invention relates to a silt silty clay layer deep foundation pit base reinforcing treatment method. The method mainly comprises the following steps that base leveling and sampling detection are conducted; multiple rows of steel pipes are arranged at the positions, close to the side wall of the deep foundation pit, of the base, and the steel pipes are filled with pressure relief filler; a corresponding grouting material is configured according to a detection result; drilling and grouting are conducted; slurry overflowing treatment is conducted; and the pipes are drawn up. The method is usedfor reinforcing the silt silty clay layer deep foundation pit foundation, can reduce protrusions generated in the grouting process of the deep foundation pit foundation, improves the reinforcing effect of the foundation, improves the safety of follow-up construction, and reduces impact and damage to the whole structure of the deep foundation pit in the reinforcing process of the deep foundation pit foundation.
本申请涉及一种淤泥质粉质黏土层深基坑基底加固处理方法，主要包括以下步骤：基底平整及取样检测；在基底上靠近深基坑侧墙的位置设置多排钢管，并在钢管中填充泄压填充料；根据检测结果配置相应的注浆材料；钻孔注浆；冒浆处理；拔管。本申请用于对淤泥质粉质黏土层深基坑基底进行加固处理，其能降低深基坑基底注浆过程中产生的隆起，改善基底的加固效果，提高后续施工的安全性，减少深基坑基底加固过程中对深基坑的整体结构产生的冲击与损坏。
