Recharge well with dredging structure
The invention discloses a recharge well with a dredging structure, which comprises a well casing mounted in a borehole, a filter is arranged at the lower part of the well casing, and a well casing filter screen is arranged on the outer side of the filter and is arranged in a confined aquifer to be recharged; a filtering layer, a water-resisting layer and a plugging layer are sequentially filled between the well casing and the well hole from bottom to top, the filtering layer is arranged in a confined aquifer to be recharged, a plurality of water injection steel pipes which are evenly distributed in the circumferential direction are embedded in the filtering layer, the water-resisting layer and the plugging layer, the lower portion of each water injection steel pipe is a water outlet section, and water outlet holes and water injection filter screens are arranged on the water outlet sections. The well casing is arranged in a to-be-recharged confined aquifer and is communicated with the well casing through a filter layer; a sealing cover is installed at the upper end of the water injection steel pipe. High water head pressure is applied through the water injection steel pipe, so that underground water at the filter flows into the well pipe, the lifting effect is achieved, the blockage condition at the filter screen is dredged, the situation that the surrounding water level drops due to lifting of the recharge well is avoided, and the effect of protecting the environment is achieved.
本发明公开了一种自带疏通结构的回灌井，包括安装在井眼内的井管，井管的下部为过滤器，过滤器外侧设有井管过滤网，设置在拟回灌承压含水层中；在井管和井眼之间从下至上依次填装有过滤层、隔水层和封堵层，过滤层设置在拟回灌承压含水层中，在过滤层、隔水层和封堵层内埋设有若干根沿周向均布的注水钢管，注水钢管的下部为出水段，设有出水孔和注水过滤网，设置在拟回灌承压含水层中，通过过滤层与井管连通；在注水钢管的上端安装有密封盖。本发明通过注水钢管施加高水头压力，从而使得过滤器处地下水向井管内流动，实现回扬效果，对滤网处堵塞情况进行疏通，避免回灌井回扬引起周围水位下降，从而达到保护环境的效果。
