In-situ mucky soil deep foundation pit construction method
The invention discloses an in-situ mucky soil deep foundation pit construction method. The method comprises the following steps that an area to be treated is divided into a plurality of square blocks and a plurality of layers of step areas; sequentially executing the following operations on each step area in the to-be-treated area from top to bottom: adding a curing agent, stirring, standing, digging out the mucky soil after the mucky soil is cured, and arranging a protective layer; and a curing agent is added into the mucky soil at the bottom of the lowermost step area, standing is conducted after even stirring, and construction is completed after the mucky soil meets the curing strength design requirement. A soil stabilizer is adopted for foundation pit mucky soil solidification, a single process is adopted for construction, and the excavation difficulty is reduced; according to the in-situ mucky soil deep foundation pit construction method, the bottom of a foundation pit and a side slope are solidified, the construction process is simple, and site construction is convenient and fast; the anti-seepage performance of the solidified soil body is remarkably improved, and foundation pit water seepage can be effectively reduced; the solidification time of the solidified soil is short, the project construction period is shortened, and good economic benefits are achieved.
本发明公开了原位淤泥质土深基坑施工方法，包括以下步骤：将待处理区域分别划分为若干正方形区块和若干层台阶区域；对待处理区域中的每个台阶区域按照从上到下的顺序依次执行如下操作：加入固化剂、搅拌后静置、淤泥质土固化后挖出、设置保护层；在最下层台阶区域底部的淤泥质土中加入固化剂，搅拌均匀后静置，淤泥质土满足固化强度设计要求后，施工完成。采用土壤固化剂进行设基坑淤泥质土固化，采用单一工艺施工，减少开挖难度；原位淤泥质土深基坑施工方法，对基坑底部及边坡进行固化，施工工艺简单，现场施工便捷；固化处理后土体防渗性能显著提高，可有效减少基坑渗水；固化土凝固时间较短，节约工程工期，有较好的经济效益。
