工业废渣联合固化疏浚淤泥填筑路基施工技术

摘要

Coastal soft foundation areas with dense rivers,rivers produce large number of high water content dredged sludge.One hand dredged sludge occupys large yards,on the other hand,the construction of highway subgrades needs large number of lightweight fillers.Large amount wastes of phosphorus gypsum,soda residue,waste tires are produced in industrial production.The construction technology of solidified dredged sludge with phosphogypsum residue and waste tire powder,has been successful.%滨海软土地区河网密布,河网疏浚产生大量高含水率疏浚淤泥,淤泥需占用大量堆场,若制作为轻质填料,可用于填筑路基;工业生产产生大量磷石膏、碱渣、废旧轮胎等废弃物也需处理.对此采用磷石膏碱渣和废弃轮胎橡胶粉联合固化疏浚淤泥填筑路基,实践证明效果良好.
