Production process for solidifying and regenerating roadbed filler by using mucky muck
The invention discloses a production process for solidifying and regenerating roadbed filler by using mucky muck. The production process comprises the following steps that the using amount of a curing agent is determined according to grain composition, plasticity index and water content of muck; the mucky muck is mixed with the curing agent to realize granulation; granules are turned, thrown and maintained to realize water reduction and homogenization of the granules; and the moisture content of the granules is detected, and when the moisture content of the granules is not higher than the optimal moisture content+5%, production of the regenerated roadbed filler is completed by taking the homogenized granules as the regenerated roadbed filler. According to the production process, the natural mucky muck can be directly solidified, pretreatment links such as drying and crushing or water distribution fluidization are not needed, the using amount of the curing agent is small, the treatment period is short, the regenerated filler is in the shape of loose and compactable powder which is appropriate in water content and viscosity, transfer and road construction operation are easy, secondary ash doping is not needed, the filler can be directly paved and rolled, and the roadbed bearing capacity requirement is met after compaction. The technological process is simple and efficient, and industrial application and large-scale popularization are easy.
本发明公开了一种淤泥质渣土固化再生路基填料的生产工艺。包括根据渣土的颗粒级配、塑性指数和含水率确定固化剂用量；将淤泥质渣土与固化剂混合实现粒料化；对粒料翻抛养护，实现减水和粒料均匀化；检测粒料含水率，当粒料含水率不高于最佳含水率+5％，以均匀化后的粒料作为再生路基填料，完成再生路基填料的生产。本发明的生产工艺，可对天然淤泥质渣土直接固化处理，无需干燥破碎或配水流态化等预处理环节，固化剂用量较少，处理周期短，再生的填料呈含水率及粘度适宜、松散可压实的粉粒状，易于转运及道路施工操作，无需二次掺灰，可直接摊铺碾压，压实后满足路基承载能力要求，本发明的工艺流程简练高效，易于产业化应用及大规模推广。
