Recharge well structure and recharge construction method
The invention discloses a recharge well structure which comprises a recharge well, a well pipe, a water stop ring piece and a recharge pipeline assembly. The well casing is coaxially arranged in the recharge well, and filler is filled between the outer wall of the well casing and the inner wall of the recharge well; the well pipe comprises a precipitation pipe section, a filtering pipe section and a solid pipe section which are sequentially connected from bottom to top, and the water stop ring piece is arranged on the outer wall face of the solid pipe section. The recharge pipeline assembly comprises a recharge pipeline, the upper end of the recharge pipeline is located on the upper portion of the recharge well and communicated with an external water source, and the lower end of the recharge pipeline extends into the filter pipe section of the well pipe. The invention further provides a recharge construction method. The recharge well structure has the beneficial effects that the seepage path of underground water is increased by arranging the water stop ring piece on the well pipe section, meanwhile, the upper backfill layer is blocked by adopting a secondary grouting process, the maximum recharge pressure allowed by the recharge well structure is effectively ensured, and the water level of a high-water-head confined aquifer area is increased by adopting a pressurized recharge measure.
本发明公开了一种回灌井结构，包括回灌井、井管、止水环片和回灌管路组件；所述井管同轴设于回灌井内，井管的外壁与回灌井的内壁之间填充有填料；所述井管包括自下而上依次连接的沉淀管段、过滤管段和实管段，所述止水环片设于实管段的外壁面上；所述回灌管路组件包括回灌管道，所述回灌管道的上端位于回灌井上部，与外部水源连通，回灌管道的下端伸入井管的过滤管段内。本发明还提供了一种回灌施工方法。本发明的有益效果为：本发明通过在井管段设置止水环片，增加地下水的渗流路径，同时采用二次注浆工艺封堵上部回填层，有效的保证回灌井结构允许的最大回灌压力，采用加压回灌的措施，抬升高水头的承压含水层地区的水位。
