Gravel filter layer filling device for dewatering well and using method of gravel filter layer filling device
The invention discloses a gravel filtering layer filling device for a dewatering well and a using method, and relates to the technical field of municipal engineering construction. The blanking well pipe comprises an end hopper head, extension sleeves and a bottom sleeve, the top of the end hopper head is conical, internal threads are installed at the bottom of the end hopper head, a plurality of sets of extension sleeves are installed, threaded branch openings are installed at the tops of the extension sleeves, internal threads are formed in the bottoms of the extension sleeves, and the bottom sleeve is sleeved with the threaded branch openings. The internal thread is in threaded connection with the threaded branch opening of the next group of long sleeve; the bottom sleeve is in threaded connection with the extension sleeve located on the bottom layer. The technical problem that when a dewatering well point is constructed in the soft soil layer, the upper portion of the soft soil layer is prone to collapse, and the gravel filter layer is difficult to fill into the well after drilling is completed is solved.
本发明公开了一种降水井填充砂石滤层装置及使用方法，涉及市政工程施工技术领域。下料井管，所述下料井管包括端部料斗头、接长套筒和底部套筒，所述端部料斗头的顶部呈锥形，所述端部料斗头的底部安装有内螺纹，所述接长套筒安装有多组，所述接长套筒的顶部安装有螺纹支口，底部开设有内螺纹，所述内螺纹与下一组接长套筒的螺纹支口相螺纹连接；所述底部套筒与位于底层的接长套筒相螺纹连接。本发明解决了在软土层施工降水井点时因软土层上部易塌方，钻孔完成后砂石滤层难以填充入井内的技术问题。
