Roadbed filling material prepared from waste shield slurry and preparation method of roadbed filling material
The invention discloses a roadbed filling material prepared from a waste shield slurry material and a preparation method of the roadbed filling material, and relates to the technical field of roadbed filling materials, the roadbed filling material comprises the following components in parts by weight: 40-60 parts of waste shield slurry, 10-30 parts of water and 20-30 parts of a cementing material; the cementing material comprises 5-10 parts of phosphogypsum, 20-40 parts of fly ash, 20-40 parts of slag powder and 10-20 parts of cement. The preparation method comprises the following steps: S1, sieving the waste shield slurry, and preparing materials; s2, preparing gelling slurry; s3, stirring the gelling slurry and the waste shield slurry to obtain the roadbed filling material. The waste shield slurry is used for replacing sand-mixed stone and graded broken stone, the composition of the cementing material is improved according to the characteristics of the waste shield slurry, the unconfined compressive strength of the roadbed filling material finally obtained through stirring meets the requirement for the roadbed filling material in the national standard, the waste shield slurry can be consumed on a large scale, and the roadbed filling material has the advantages that the cost is low, and the economic benefit is high. The environmental benefit and the economic benefit are outstanding.
一种采用废弃盾构泥浆料制备的路基填筑料及其制备方法，涉及路基填筑料技术领域，所述路基填筑料包括按重量份计的40~60份废弃盾构泥浆、10~30份水和20~30份胶凝材料；所述胶凝材料包括5~10份磷石膏、20~40份粉煤灰、20~40份矿渣粉和10~20份水泥，所述制备方法包括S1将废弃盾构泥浆过筛，备料；S2配置胶凝浆液；S3将胶凝浆液和废弃盾构泥浆搅拌得到路基填筑料。本发明以废弃盾构泥浆代替砂夹石及级配碎石，并针对废弃盾构泥浆的特性改善了胶凝材料的组成，最终搅拌得到的路基填筑料无侧限抗压强度满足国家规范中的对于路基填筑料的要求，废弃盾构泥浆可以得到大规模的消纳，环境效益和经济效益突出。
