Phosphogypsum weak tailing pond seepage drainage construction method
The invention discloses a seepage drainage construction method for a phosphogypsum soft tailing pond, belongs to the technical field of seepage drainage of soft tailing ponds, and aims to solve the technical problems that when an existing traditional seepage drainage method for the soft tailing ponds is used in the phosphogypsum soft tailing ponds, the seepage drainage effect is poor, the piping phenomenon is likely to occur, and the dam break risk is increased. The seepage drainage holes in the seepage drainage pipe can be prevented from being blocked by fine particles through the formation of the inverted filter layer, water in the dam body can be more efficiently drained through the seepage drainage pipe, and therefore the seepage drainage effect can be improved; water liquid enters the drainage pipe through the inverted filter layer and cannot dissolve the phosphogypsum tailings, so that the possibility of piping can be effectively reduced, and the risk of dam break is reduced.
一种磷石膏软弱尾矿库排渗施工方法，属于软弱尾矿库排渗技术领域，为了解决现传统的软弱尾矿库排渗方法在磷石膏软弱尾矿库使用时，排渗效果不佳，且易产生管涌现象，增加了溃坝风险的技术问题；本发明通过反滤层的形成能够避免排渗管上的排渗孔被细小颗粒堵塞，使坝体内的水能够更高效的通过排渗管排出，从而能够提升排渗效果，同时通过反滤层的设置和碎石作业坑的阻挡，水液通过反滤层进入排渗管内部不会溶解磷石膏尾矿，从而能够有效降低出现管涌现象的可能，降低了溃坝的风险。
