Protection method for improving soil slope to resist rainwater erosion through phosphogypsum and microorganisms
The invention provides a protection method for improving a soil slope to resist rainwater erosion through phosphogypsum and microorganisms. The protection method is characterized by including the steps that (1), bacillus pasteurii is put in a culture medium, a microorganism solution is prepared, urea, calcium chloride and water are mixed, and cementing liquid is prepared; (2), the mixture, the microorganism solution and water are mixed and stirred uniformly, the cementing liquid and water are added, the materials are mixed, and improved mixture slurry is prepared; and (3), a wet spraying method is adopted for spraying the improved mixture slurry onto the surface of the slope twice, then the improved mixture slurry and grass seeds are stirred uniformly, the material is sprayed to the surface of the slope at a time, the slope is covered with non-woven fabric, the non-woven fabric is firmly bound, and water is sprayed to the slope every day for maintenance. By means of the method, the protection requirements of rainwater wash resistance and slope ecological greening of the soil slope made of loess, gravelly soil and the like can be met, the phosphogypsum can be consumed, occupation ofcultivated land is reduced, and available phosphorus can promote plant growth. By means of the phosphogypsum improved with the microorganisms, harmful elements can be cured, and environmental pollution is reduced.
一种采用磷石膏与微生物改良土质边坡抗雨水侵蚀的防护方法，其特征是该方法包括：（1）将巴氏芽孢杆菌放入培养基中配制成微生物溶液，将尿素、氯化钙与水混合配制成胶结液；（2）将混合料、微生物溶液和水混合搅拌均匀，再加入胶结液与水混合配制成改良混合料泥浆；（3）采用湿喷方法，将改良混合料泥浆分两次喷射至边坡表面，然后将改良混合料泥浆与草籽拌和均匀，一次喷射至边坡表面，覆盖无纺布并绑扎牢固，每天进行喷水养护。该方法可以满足包括黄土、碎石土等土质边坡抗雨水冲刷和边坡生态绿化防护要求，并可消耗磷石膏，减少对耕地的占用，且有效磷可以促进植物生长。经微生物改良后的磷石膏，可以实现对有害元素的固化，降低对环境的污染。
