Pressure-bearing layer dewatering well plugging device and method
The invention relates to the technical field of dewatering well plugging, in particular to a pressure-bearing layer dewatering well plugging device and method. Comprising a device body, the device body comprises a first preset part, and the first preset part is used for being placed in an existing dewatering well; the first preset piece comprises a hollow well pipe, an inner water stop steel plate is coaxially installed at a pipe opening in one end of the well pipe, and a water passing hole used for allowing a galvanized steel pipe to be inserted is formed in the inner water stop steel plate. An annular installation groove used for installing water swelling glue is formed in the position of the inner water stop steel plate. According to the device disclosed by the invention, the pressing rod is matched with the second annular groove and the first annular groove, so that circumferential inward compaction and downward compaction of water-swelling glue are respectively realized; therefore, on the premise that a constructor does not enter the well pipe, the water swelling glue on the lower portion of the well pipe can be conveniently compacted on the galvanized steel pipe.
本发明涉及降水井封堵技术领域，具体地说，涉及一种承压层降水井封堵装置及方法。包括装置本体，装置本体包第一预设件，第一预设件用于放入既有降水井；第一预设件包括空心的井管,井管的一端管口处同轴安装有内止水钢板，内止水钢板处形成有用于插入镀锌钢管的过水孔；内止水钢板处形成有用于安装遇水膨胀胶的环形安装槽。本发明能够通过压杆与第二环形槽和第一环形槽之间的配合，以分别实现对于遇水膨胀胶的周向向内压实和向下压实；从而使得施工人员能够在不进入井管内的前提下，较为方便地对于井管下部的遇水膨胀胶压实于镀锌钢管上。
