Method for protecting surrounding soil or building during foundation pit construction
The invention discloses a method for protecting surrounding soil or buildings during foundation pit construction. The method comprises the following steps: firstly, measuring the water level of underground water between a foundation pit and a protected building; the soil body above the underground water between the foundation pit and the protected building is heated for a set heating duration; grouting is conducted on the soil body above the underground water between the foundation pit and the protected building, and the injected cement paste enters the heated soil body; and after the cement paste injected into the heated soil body is condensed, grouting and water pumping are conducted on the soil body in the underground water between the foundation pit and the protected building, water pumping and grouting are conducted synchronously, and the grouting positions are located around the water pumping position. The construction method has the effect of reducing the influence on surrounding soil and buildings during foundation pit construction.
本申请公开了一种在基坑施工时保护周边土体或建筑物的方法，其先测量基坑与被保护建筑物之间的地下水的水位；再对基坑与被保护建筑物之间的地下水上方的土体加热设定的加热时长；之后往基坑与被保护建筑物之间的地下水上方的土体注浆，注入的水泥浆进入被加热的土体中；待注入加热的土体中的水泥浆凝结后，对基坑与被保护建筑物之间的地下水中的土体注浆和抽水，抽水和注浆同步进行，注浆位置位于抽水位置的四周。本申请具有减少基坑施工时对周边土体和建筑物的影响的效果。
