Precipitation well structure and pile foundation construction method transformed by using precipitation well
The invention provides a dewatering well structure and a pile foundation construction method using dewatering well reconstruction, the dewatering well structure comprises a steel pipe as a dewatering well main body, the pipe wall of the steel pipe is provided with a plurality of water guide holes close to the bottom end; the backfill filter material is arranged between the steel pipe and the well pit; the grouting pipe is arranged between the steel pipe and the backfill filter material and fixedly arranged on the outer wall of the steel pipe, a grouting device inserted into the bottom of the well pit is installed at the bottom end of the grouting pipe, a plurality of grouting holes are formed in the pipe wall of the grouting pipe in the height direction at intervals, and outlets of the grouting holes face the backfill filter material; according to the sealing structure, water outside the well pit sequentially passes through the backfill filter material, the water guide hole and the hole diameter of the water filter pipe to be accumulated in the steel pipe. The dewatering well structure is simple in structure and convenient to construct; the structural advantages of the steel tube well can be fully exerted, and the steel tube well can serve as a structural foundation.
本发明提供了一种降水井结构及利用降水井改造的桩基施工方法，包括：钢管，作为降水井主体，其管壁靠底端处开设有若干导水孔；回填滤料，布置在所述钢管与井坑之间；注浆管，布置于所述钢管与所述回填滤料之间，且固设于所述钢管外壁，且底端安装有插入井坑底部的注浆器，所述注浆管的管壁沿高度方向间隔开设有多个注浆孔，所述注浆孔的出口朝向所述回填滤料布置；密封结构，井坑外部的水依次通过所述回填滤料、导水孔以及所述滤水管的孔径聚积在所述钢管的内部。本发明的降水井结构，结构简单，施工便捷；能充分发挥钢管井的结构优点，使其可兼做结构基础。
