Green backfilling method based on all-solid-waste engineering soil
The invention discloses a green backfilling method based on all-solid waste engineering soil, and relates to the technical field of backfilling of various deep, long and narrow irregular spaces such as grooves and fat grooves in house construction engineering and road and bridge engineering. The backfill material is composed of saturated surface dry filter pressing alkaline residues, carbide slag, ardealite and slag in a specific particle size range and replaces traditional natural soil to serve as a backfill matrix, the activity of a slag material is stimulated by means of alkaline materials such as the alkaline residues, under the action of a proper amount of water, the material is promoted to be subjected to a hydration gelling reaction, and the performance of the material is further improved. While the later maintenance and repair cost is saved, the environmental pollution is reduced, and the resource utilization of solid waste materials is promoted.
本发明公开了一种基于全固废工程土的绿色回填方法，涉及房屋建筑工程、道路桥梁工程的各类沟槽、肥槽等深而狭长的不规则空间回填技术领域。由特定粒径范围的饱和面干压滤碱渣、电石渣、磷石膏和矿渣构成，替代传统天然土壤作为回填基体，借助碱渣等碱性材料激发矿渣材料活性，在适量水分的作用下，促使材料发生水化胶凝反应，进一步提升了材料的性能。在节省后期维护和维修的成本的同时，减少了环境污染，并促进了固废材料的资源化利用。
