CONSTRUCTION METHOD FOR IMPROVING EARTH-STONE MIXED EMBANKMENT USING PHOSPHOGYPSUM AND MICROBE
- Figure 1 The present disclosure relates to a construction method for improving an earth-stone mixed embankment using phosphogypsum and microbes, including the following steps: (1) placing Bacillus pasteurii into a culture medium to prepare a microbial solution, and mixing urea and calcium chloride with water to prepare a cementing fluid; (2) mixing and stirring a mixture, the microbial solution and water, adding the cementing solution well, and mixing the cementing fluid with water to prepare an improved mixture; and (3) leveling and compacting original ground, laying geomembranes, the improved mixture, and geogrids, laying a last layer of geomembrane on the top surface of the embankment after pavement of the embankment, and paving a roadbed. The construction method can meet construction requirements of highway embankment projects and roadbed projects of first-grade and other grades of roads, and consume solid waste phosphogypsum. 4 4 .4 4. 444444 4 4 4* 4 4 44 'A ' .~ * .: . 4 4. 44 .4 4 4 4 44 444 .4 4 44 44 444 4 4 4 4 4 44 44. .,* * 4 * *44 4'1 4 4 441, 4 4 4*4 44 4 4~1 44444 4 4444 444 *4~ 4 44 ~ 44 - Al' 4 . 4 . * ' , * ~ r't ,. 44 4444444 '44*4 4 *444 44444 44 444 44* 44 4444 444~44 ~ 44444 4 4 ~ 444 4 .4 44 4 4 ~4 44 4 *44 444 44,444 444444444 4 444444 4~444 44 ~441 4 4 . 4444 * 444 * 4,, ~ ' '': 44 4444~ 4 444 '~j'4 4 4t 4 4 44 4 4 4 4 44 44 44 ~Y4 t4;4:tt:K.
