Modified aeolian sand as well as preparation method and application thereof and roadbed filling and compacting construction method
The invention discloses modified aeolian sand and a preparation method and application thereof and a roadbed filling and compacting construction method, and belongs to the technical field of road construction, and the modified aeolian sand comprises aeolian sand, quicklime, magnesium aluminum silicate and sodium silicate. The preparation method comprises the following steps: (1) grinding quicklime, magnesium aluminum silicate and sodium silicate to obtain a mixture; (2) adding water into the mixture, and stirring to prepare a feed liquid; and (3) adding the aeolian sand into the feed liquid for soaking, and filtering to obtain the modified aeolian sand. Compared with the prior art, by modifying the surface of the aeolian sand, the problem that the water content of the surface of the aeolian sand is not easy to control is solved, the compaction quality is ensured, meanwhile, the construction difficulty is reduced, and the roadbed filling compaction construction speed is increased.
本发明公开了一种改性风积沙及其制备方法、应用和路基填筑压实施工方法，属于道路施工技术领域，所述改性风积沙，包括风积沙、生石灰、硅酸铝镁和硅酸钠。所述制备方法，包括：(1)将生石灰、硅酸铝镁和硅酸钠研磨，得到混合物；(2)将混合物加水搅拌，制备成料液；(3)将风积沙加入料液中浸泡，过滤，得到改性风积沙。相比现有技术，本发明通过对风积沙表面进行改性，解决了风积沙表面含水量不易控制的问题，保证了压实质量，同时，降低了施工难度，提高了路基填筑压实施工速度。
