Recharge anti-seepage system for controlling collapse of wellhead of brine extraction well in salt lake and construction method of recharge anti-seepage system
The invention provides a recharge anti-seepage system for controlling collapse of a wellhead of a salt lake brine extraction well and a construction method of the recharge anti-seepage system. The recharge anti-seepage system for controlling salt lake brine extraction well mouth collapse comprises a water stop anti-seepage system which comprises a base artificial water-resisting layer located in a salt lake and a water stop anti-seepage wall arranged in the circumferential direction of the base artificial water-resisting layer, the bottom end of the water stop anti-seepage wall is embedded into the base artificial water-resisting layer, and the top end of the water stop anti-seepage wall can penetrate out of the salt lake; the brine recharge device comprises a recharge well, a pressure pump arranged on one side of the recharge well and a brine preparation box communicated with the pressure pump, the recharge well is located in the water stop diaphragm wall, the interior of the brine preparation box is used for storing recharge brine liquid, and the pressure pump is used for pumping the recharge brine liquid into the recharge well. According to the technical scheme, the bearing capacity of the salt layer framework of the wellhead can be improved, the salt layer framework fully rebounds, the problem that the wellhead of the brine mining well collapses due to continuous reduction of the underground water level is solved, and therefore the service life of the brine mining well is prolonged.
本发明提供了一种控制盐湖采卤井井口塌陷的回灌防渗系统及其施工方法。控制盐湖采卤井井口塌陷的回灌防渗系统包括：止水防渗体系，包括位于盐湖内的基底人工隔水层和绕基底人工隔水层的周向设置的止水防渗墙，止水防渗墙的底端嵌入基底人工隔水层，止水防渗墙的顶端能够穿出盐湖；盐水回灌装置，包括回灌井、设置在回灌井一侧的加压泵和与加压泵连通的盐水配置箱，其中，回灌井位于止水防渗墙内，盐水配置箱内用于储存回灌盐水液，加压泵用于将回灌盐水液泵送入回灌井内。本发明的技术方案能够提高井口盐层骨架的承载力，使得盐层骨架充分回弹，解决因地下水水位持续降低导致采卤井井口塌陷的问题，从而延长采卤井的使用寿命。
