AI Technical Summary
Traditional clay ball sealing devices have poor water-stopping effect in groundwater recharge wells. They cannot effectively prevent recharge water from rising through the gap between the well wall and the borehole wall, resulting in the recharge water not flowing evenly to the surrounding strata.
It adopts a tubular structure, including sedimentation pipe, filter pipe and well pipe. A filter layer is provided between the pipe wall and the borehole wall. The top is sealed with a water-stop rubber ring and a water-stop steel sheet, and the iron cover is fixed by a snap-fit component to ensure sealing and stability.
It effectively prevents pressurized water from seeping in, allowing it to flow evenly to the surrounding strata. It has a good water-stopping effect, high shear strength, and can withstand pressure impact. The device is also recyclable and reusable.
