在地下水源丰富、承压水水头高的深基坑场地,坑内一旦发生管涌不仅直接影响基坑自身安全,而且严重影响周边建筑物及地下管线的安全。文章介绍的可调水量浅井是通过对管涌点处水流加以引流,并通过改变特制滤芯与井管搭接长度以达到调节水量为目的的管井。经过现场实验与论证,成功处理了基坑管涌事故,既快速又经济。
In the deep foundation pit with rich underground water and high water pressure, the occurrence of piping in the pit not only directly affects the safety of the foundation pit, but also seriously affects the safety of surrounding buildings and underground pipelines. The article describes the adjustable water capacity of shallow wells by pouring water flow at the point, and by changing the special filter and the well pipe lap length to achieve the purpose of regulating the amount of water well. After field experiments and demonstration, successfully handled the foundation pit accident, both fast and economical.
