Filling construction method for high liquid limit soil in-situ solidified roadbed
The invention belongs to the technical field of roadbed solidification, and particularly relates to a filling construction method for a high liquid limit soil in-situ solidified roadbed, the filling construction method comprises the operation steps of construction preparation, survey setting-out, in-situ mixing, paving, rolling, curing and the like, and the filling mixture comprises the following components in parts by mass: 100 parts of tedded soil, 20-30 parts of solid waste mixing agent and 3-5 parts of cement; the solid waste mixing agent comprises 50-60 parts of limestone slag; 5-10 parts of quick lime; 5-10 parts of fly ash; 1-2 parts of a penetrant; according to the method, the solid waste mixing agent is doped into the high liquid limit soil, calcium oxide reacts with water to generate calcium hydroxide, meanwhile, moisture in the high liquid limit soil is evaporated through heat generated when calcium oxide is digested, the moisture content in the mixture is reduced, meanwhile, improvement of the construction technology is combined, and the purpose of compacting the soil is achieved; and the engineering quality of the roadbed can be obviously improved.
本发明属于路基固化技术领域，具体涉及一种高液限土就地固化路基的填筑施工方法，包括施工准备、测量放样、现场拌和、摊铺及碾压和养生等操作步骤，其中填筑混合料的配比为按照质量份数计算，包括翻晒土100份，固废拌合剂20~30份，水泥3~5份；所述固废拌合剂包括石灰石渣50~60份；生石灰5~10份；粉煤灰5~10份；渗透剂1~2份；本发明通过在高液限土中掺入固废拌合剂，使得氧化钙与水反应生成氢氧化钙，同时利用氧化钙消解时产生的热量蒸发高液限土中的水分，降低混合料中的含水量，同时结合施工工艺的改进，达到土壤密实的目的，能够明显提高路基的工程质量。
