Description
Technical Field

Background
Phosphogypsum belongs to class II general industrial solid waste. The adjusting water tank is an important flood storage and production maintaining building of the phosphogypsum storage yard, and the full storage basin seepage prevention is needed to ensure the normal operation of the storage yard. Along with the rising of the underground water level in the flood season, the anti-seepage films can be torn at the welding seams, the pipe penetrating film joint parts and the like among the anti-seepage films under the action of huge buoyancy. In order to prevent the seepage-proofing system from polluting ground water due to leakage points, drainage blind ditches are arranged under the seepage-proofing membrane of the adjusting pool to drain ground water according to the standard requirements, and flood interception ditches are arranged at the top of the pool to drain surface water. However, after the adjusting water tank is put into operation, the seepage guiding system arranged under the seepage preventing film is often failed due to pipeline blockage, and the seepage guiding system can be maintained only after the process water stored in the water tank is emptied in the dead water period, so that the construction difficulty is high. Most of rainfall in karst development areas infiltrates underground water through earth surface water falling holes, solution gaps and solution gaps to generate karst leakage, the underground water level rises faster, and the risk of tearing of the impermeable membrane is further aggravated. In addition, the common protective net is adopted at the top of the pool, so that the impact force of the rolling stones cannot be resisted, and once the rolling stones fall into a storage yard, the seepage guiding system arranged under the seepage preventing film is easily damaged, so that immeasurable loss is caused. Therefore, the flood intercepting ditches are only arranged at the top of the warehouse, and the seepage guiding system is arranged under the membrane, so that the seepage preventing membrane in the warehouse cannot be effectively protected, and in particular, in karst development areas, once the seepage preventing system is destroyed, large production accidents and even production stopping and rectifying changes can be generated.

In the structure, the thickness of the red clay layer is more than or equal to 30cm, and the compactness is more than or equal to 92%; the red clay layer is smoothly connected with the natural slope.
