Fabricated roadbed formed by punching dehydrated dredged sludge solidified soil
Dehydrated dredged sludge is stabilized by adopting quick lime, a proper amount of ferric oxide is doped, so that the dewatered dredged sludge becomes a carrier of a quick lime hydration product Ca (OH) 2, the specific surface area is enlarged, and high-concentration CO2 is further adopted for mineralization, so that the quick lime hydration product Ca (OH) 2 is obtained. And finally, the fabricated roadbed of a tenon-and-mortise structure is produced through impact forming, and recycling of dredged sludge and carbon sequestration are achieved. The invention provides a new roadbed material and a new roadbed structure, can be spliced and constructed on site, and has the advantages of energy conservation, simplicity and convenience in construction, economy and effectiveness.
本发明公开了一种脱水疏浚淤泥固化土冲压成型装配式路基，通过对脱水后的疏浚淤泥采用生石灰稳定，再适量掺入氧化铁，使之成为生石灰水化产物Ca(OH)2的载体，扩大比表面积，进一步采用高浓度CO2矿化，最后冲击成型生产出榫卯结构的装配式路基，实现疏浚淤泥再利用以及固碳；本发明提供了一种路基新材料新结构，可进行现场拼接施工，具有节省能源、施工简便、经济有效的优势。
