Assembled press-in type drainage well device and drainage well construction method
The invention provides an assembled press-in type drainage well device and a drainage well construction method. The assembled press-in type drainage well device comprises a prefabricated well completion device and a well completion sleeve detachably connected with the prefabricated well completion device. The prefabricated well completion device comprises a waterproof section, an assembled porous permeable section, a precipitation section, an end sealing device and a well wall well washing device. The assembled porous permeable section is of a multi-layer hollow tubular structure comprising a plurality of permeable pipes, the upper end face of the innermost permeable pipe is connected with the lower end face of the impermeable section, the precipitation section is connected to the bottom of an inner hole of the innermost permeable pipe, and the end sealing device is provided with a pile tip connected to the lower end face of the assembled porous permeable section. The well wall well washing device is connected to the upper end face of the assembly type porous permeable section and provided with at least one water outlet. And the well completion sleeve is sleeved outside the assembled porous permeable section, and the bottom of the well completion sleeve is movably connected with the end sealing device. The construction process is simplified, the well completion quality is improved, and the well completion period is shortened.
本发明提供了一种组装压入式疏干井装置以及疏干井施工方法，组装压入式疏干井装置包含有预制成井装置以及与预制成井装置可拆卸连接的成井套管；预制成井装置包含有不透水段、组装式多孔透水段、沉淀段、端部封口装置和井壁洗井装置。组装式多孔透水段为包含有多个透水管的多层中空管状结构，最内层透水管的上端面与不透水段下端面相连，沉淀段连接在最内层透水管的内孔底部，端部封口装置设有连接在组装式多孔透水段下端面的桩尖，井壁洗井装置连接在组装式多孔透水段上端面，井壁洗井装置设有至少一排水口；成井套管套置在组装式多孔透水段外且底部与端部封口装置活动连接。本发明简化施工流程，提高成井质量，节约成井工期。
