Deep foundation pit dewatering well spiral plugging device and plugging method
The invention relates to the technical field of deep foundation pit dewatering well plugging construction, in particular to a deep foundation pit dewatering well spiral plugging device and plugging method. The device comprises a filter pipe, a spiral steel casing pipe, a spiral rod and a rubber gasket. A thread is arranged on the inner wall of the spiral steel casing pipe, the spiral steel casingpipe is welded with the filter pipe to form a well pipe, the spiral steel casing pipe is welded to the middle of the filter pipe, the well pipe is lowered into a dewatering well, the spiral steel casing pipe is mounted on a wellhead position, the spiral rod is in threaded connection into the spiral steel casing pipe, the outer side of the upper portion of the spiral rod is sleeved with the rubbergasket, and two lug rings are mounted on the top of the spiral rod. The device has the advantages of being rapid in plugging, small in engineering amount, easy to operate, and small in influence on structure integrality and is suitable for dewatering well plugging in most deep foundation pits.
本发明涉及深基坑降水井封堵施工技术领域，具体涉及一种深基坑降水井螺旋式封堵装置及封堵方法。包括滤管、螺旋钢套管、螺旋杆和橡胶垫片，螺旋钢套管内壁带有螺纹，螺旋钢套管与滤管焊接形成井管，螺旋钢套管焊接在滤管中部，井管下放至降水井内且螺旋钢套管安装在井口位置处，螺旋杆螺纹连接在螺旋钢套管内，螺旋杆上部外侧套有橡胶垫片，螺旋杆顶部设置有两个耳环。本发明具有封堵快速、工程量小、操作简单、对结构整体性影响小的特点，适合大多数深基坑内降水井封堵。
