中文摘要:以温州市江滨商务区桃花岛片区T05—18地块项目基坑堵漏为例,详细论述了该基坑出现渗漏的原因,并采用疏堵结合堵漏技术对该基坑进行堵漏。用导流管对漏水口进行疏水,可缓解漏水口及周围部分区域土层中的水压力,提高堵漏的成功率;再通过双液注浆的方式,截断基坑中部分水流路径,从而减小漏水口的水流量,同时对基坑起到加固作用。结果表明,疏堵结合堵漏技术在应用中具有快捷、精准、有效等特点,该基坑内57处漏水口均得到有效处理。

Application of drainage and plugging technology in treatment of leakage in the foundation pit
Abstract:In this paper, the causes of leakage to the foundation pit is illustrated in detail by the example of a construction site in Wenzhou City, where drainage and plugging technology was used to treat leakage to the foundation pit. A diversion pipe was used to drain the leakage outlets to relieve the water pressure in the soil layer of the leakage site and some surrounding areas, and to improve the success rate of leakage stoppage. Then, double liquid grouting was used to cut off part of the water flow path so as to reduce the water flow from the leakage outlets; and to reinforce the foundation pit. The results showed that drainage and plugging provided efficiency, accuracy and effectiveness in the field, with 57 leakage points in the foundation pit effectively treated.
