Method for engineering absorption application of ardealite raw slag

Abstract

The invention discloses a method for engineering absorption application of ardealite raw slag, which depends on the safe operation experience of an ardealite stockpiling reservoir with a certain wet method in Guizhou for twenty years, and the practice proves that the method can realize the reliability of the ardealite raw slag as engineering absorption. According to the method, on an accumulation body which is continuously lifted in the ardealite reservoir, after pore water of the accumulation body is discharged by taking a seepage guiding or seepage discharging measure, the accumulation body can settle greatly, the outer slope surface of the ardealite accumulation body cannot meet the safety standardization requirement, and the method is mainly used for repairing the dam slope surface by adopting dry ardealite and further perfecting a sewage disposal and diversion facility. By adopting the method, the engineering absorption of the ardealite raw slag can be achieved, sewage disposal and diversion can be achieved, a safe and stable dam body can be guaranteed, the dam slope surface is greened again, and the water treatment cost is reduced; and thus, the intrinsically safe production and operation of the ardealite warehouse are realized.

Description

technical field [0001] The invention relates to the field of safe and standardized stockpiling of phosphogypsum, in particular to realize the elimination of phosphogypsum raw slag engineering on the outer slope of a phosphogypsum warehouse, thereby achieving safe and standardized stockpiling technology; this is a new type of high-efficiency and high-quality phosphogypsum raw slag engineering Absorb technology. Background technique [0002] A phosphogypsum reservoir in Guizhou was put into use in 1999. When the accumulation dam was built, dry phosphogypsum was used to build the dam, but cracks appeared in the dam body and large settlement deformation occurred in the later stage; improve. As the phosphogypsum reservoir continues to rise, after the pore water of the pile is discharged through infiltration or drainage measures, the pile will also undergo a large settlement, resulting in the external slope of the phosphogypsum pile not meeting the requirements of safety standard...

[0002] A phosphogypsum reservoir in Guizhou was put into use in 1999. When the accumulation dam was built, dry phosphogypsum was used to build the dam, but cracks appeared in the dam body and large settlement deformation occurred in the later stage; improve

As the phosphogypsum reservoir continues to rise, after the pore water of the pile is discharged through infiltration or drainage measures, the pile will also undergo a large settlement, resulting in the external slope of the phosphogypsum pile not meeting the requirements of safety standardization

In the early stage, simple earth-covering and greening were adopted. Although the cleaning and sewage diversion was realized, the slope ratio of the dam body was far from 1:2.25, and some dam slope ratios were even lower than 1:4.
