Protection method for preventing and treating shallow landslide of soil slope by using phosphogypsum
The invention provides a protection method for preventing and treating shallow landslide of a soil slope by using phosphogypsum. The protection method is characterized by comprising the following steps of preparing anionic polyacrylamide and potassium chloride into an improver; preparing phosphogypsum, fly ash and soil into a mixture; doping the improver and water into the mixture to prepare improved mixture slurry; paving a three-dimensional vegetation net on the surface of the slope from top to bottom, and fixing the three-dimensional vegetation net; and spraying the improved mixture slurryto the surface of the slope in two times by adopting a wet spraying method, uniformly mixing the improved mixture slurry with grass seeds, spraying the mixture to the surface of the slope at one time,covering a non-woven fabric, binding and fixing, and carrying out water spraying maintenance every day. The method can meet the requirements of ecological greening protection and shallow landslide protection of an expansive soil slope, phosphogypsum can be consumed, occupation of cultivated land is reduced, pollution to the environment is reduced, and effective phosphorus can promote plant growth.
一种利用磷石膏防治土质边坡浅层滑坡的防护方法，其特征是该方法包括：将阴离子聚丙烯酰胺和氯化钾配制成改良剂，将磷石膏、粉煤灰和土配制成混合料，在混合料中掺入改良剂与水配制成改良混合料泥浆，将三维植被网自上而下铺于坡面，并将三维植被网固定，采用湿喷方法，将改良混合料泥浆分两次喷射至边坡表面，再将改良混合料泥浆与草籽拌和均匀，一次喷射至边坡表面，然后覆盖无纺布并绑扎固定，每天进行喷水养护。该方法可以满足膨胀土边坡生态绿化防护与浅层滑坡防护要求，并可消耗磷石膏，减少对耕地的占用，降低对环境的污染，且有效磷可以促进植物生长。
