CONSTRUCTION METHOD FOR PREVENTING LOESS EMBANKMENT SETTLEMENT BY USING PHOSPHOGYPSUM
The present invention provides a construction method for preventing less embankment settlement by using phosphogypsum. The method includes: (1) preparing an improver with anionic polyacrylamide and potassium chloride; (2) preparing a mixture with phosphogypsum, alkaline slag and less; (3) preparing an improving mixture by mixing the improver and water into the mixture; and (4) laying a geomembrane on an original ground, laying the improving mixture on the geomembrane, where one geogrid is laid every three layers of improving mixture; and laying a last geomembrane on the top of the embankment after the embankment is constructed, and then laying a roadbed. The method meets the improvement and construction requirements of less embankments of high-grade highways, and reduces the stock of solid phosphogypsum waste, thereby reducing the occupation of cultivated land, reducing environmental pollution, and turning waste into treasure.
