Construction method for loess embankment settlement deformation control by adopting ardealite
The invention discloses a construction method for loess embankment settlement deformation control by adopting ardealite. The method is characterized in that the method comprises the following steps of: (1) preparing an improver from anionic polyacrylamide and potassium chloride; (2) preparing phosphogypsum, alkaline slag and loess into a mixture, (3) doping the improver and water into the mixtureto prepare an improved mixture; (4) paving a geomembrane on the original ground, paving the improved mixture on the geomembrane, paving a layer of geogrid after each three layers of the improved mixture is paved, paving the last layer of geomembrane on the top surface of the embankment after the embankment construction is finished, and then paving a roadbed. The method can meet the construction requirements of the loess improved embankment of the high-grade highway, and can consume solid waste phosphogypsum, reduce the occupation of cultivated land, reduce the pollution to the environment andturn waste into wealth.
一种采用磷石膏用于黄土路堤沉降变形控制的施工方法，其特征是该方法包括：（1）将阴离子聚丙烯酰胺和氯化钾配置成改良剂，（2）将磷石膏、碱性矿渣和黄土配置成混合料，（3）在混合料中掺入改良剂与水配置成改良混合料，（4）在原地面铺设土工膜，在土工膜上铺设改良混合料，每铺设三层改良混合料铺设一层土工格栅，路堤施工完后，在路堤顶面铺设最后一层土工膜，然后再铺设路床。该方法可以满足高等级公路黄土改良路堤的施工要求，同时可以消耗固体废弃物磷石膏，减少对耕地的占用，降低对环境的污染，变废为宝。
