Water plugging method for solving foundation pit bottom water burst
The invention belongs to the field of foundation pit engineering emergency rescue governing, and particularly relates to a water plugging method for solving foundation pit bottom water burst. The technical problem of foundation pit bottom water burst is solved. The method comprises the steps that when a wide-range water burst phenomenon happens to a foundation pit bottom, the characteristics of alsoil layers of the foundation pit bottom are accurately judged in combination with an original reconnaissance report, and the relative water-resisting layer position is determined; according to the depth of a relative water-resisting layer, if the distance between the foundation pit bottom face and the relative water-resisting layer is larger than 20 meters and the area of the foundation bottom face is smaller than 500 square meters, or the distance between the foundation pit bottom face and the relative water-resisting layer is larger than 20 meters and the shape of a foundation pit is in along strip with the width smaller than 15 meters, a foundation pit bottom sealing method is selected for water plugging construction; and under the other conditions, long existing water interception heavy curtain method is selected for water plugging construction. The method is easy and convenient to construct, a specific water plugging method can be effectively selected in combination with the foundation pit shape and the foundation pit bottom soil property, and high applicability is achieved during foundation pit bottom water burst engineering rescue.
本发明属于基坑工程应急抢险治理领域，具体为一种用于解决基坑底涌水的堵水方法，解决了基坑底部涌水的技术问题。其步骤为：当基坑底发生大范围涌水现象时，结合原始勘察报告，准确判断基坑底各土层性质，确定相对隔水层位置；根据相对隔水层的深度，若基坑底面距离相对隔水层大于20米且基坑底面面积小于500平方米；或者基坑底面距离相对隔水层大于20m，且基坑形状为宽度小于15m的长条形，则选择基坑封底法进行施工堵水；其余情况均选择接长既有截水帷幕法进行施工堵水。该方法施工简便，能有效结合基坑形状和基坑底土性，选择具体的堵水方法，在基坑底部涌水工程抢险中具有较广的适用性。
