Safe and stable pure steel slag roadbed filling method
The invention relates to the technical field of roadbed engineering, in particular to a safe and stable pure steel slag roadbed filling method, which comprises the following steps: firstly, arranging a 30-50cm transition layer or water seepage protection layer at the bottom of a roadbed of a fixed non-water seepage road section, filling steel slag according to grading requirements of different layers to form an embankment and a roadbed, and carrying out layered filling according to the full width of the cross section of the roadbed. Then, a vibratory roller and a self-propelled roller which meet the self-weight requirement are selected to be combined for rolling, compaction effect monitoring is conducted through the compaction degree and porosity indexes calculated through process settlement control, and after the compaction degree and porosity meet the requirements, clay is laid on the periphery of an embankment and the periphery of a roadbed, a slope protection is formed, and roadbed filling is completed. According to the invention, guarantee is provided for structural safety and stability of steel slag roadbed filling, the potential problems of expansibility and deformation instability of roadbed filling of steel slag as stone in existing roadbed engineering are improved, and the problems of land occupation and environmental pollution caused by accumulation of a large amount of steel slag are solved.
本发明涉及路基工程技术领域，具体涉及一种安全稳定的纯钢渣路基填筑方法，首先在固定的非渗水路段的路基底部设置30～50cm的过渡层或渗水保护层，再将钢渣按照不同层位的级配要求填筑形成路堤和路床，按照路基横断面全宽分层填筑，然后选用满足自重要求的振动压路机与自行式压路机组合进行碾压，采用过程沉降控制推算的压实度和孔隙率指标进行压实效果监测，当压实度和孔隙率符合要求后，将黏土铺设在路堤外周、路床外周并形成护坡完成路基填筑。本发明为钢渣路基填筑的结构安全稳定提供了保障，改善了现有路基工程中钢渣作为石料路基填筑潜在的膨胀性、变形不稳定问题，解决了钢渣大量堆积导致的土地占用与环境污染问题。
