Coal-fired slag-based foam light soil roadbed and construction method thereof
The invention relates to the field of roadbed construction materials and construction methods, and particularly discloses a coal-fired furnace slag-based foam light soil roadbed and a construction method thereof.The coal-fired furnace slag-based foam light soil roadbed is formed by laying coal-fired furnace slag-based foam light soil, and the coal-fired furnace slag-based foam light soil comprises coal slag-based aggregate; the coal cinder-based aggregate comprises coal cinder-based microspheres, and the preparation of the coal cinder-based microspheres comprises the following steps: adding a biological carbon source and coal cinder powder into a glacial acetic acid solution, uniformly stirring, and dropwise adding into a sodium hydroxide solution to obtain condensed beads; and washing the gel beads to be neutral, freeze-drying, and calcining under the protection of nitrogen to obtain the coal cinder-based aggregate. The roadbed construction method comprises the following steps: S1, excavating a roadbed; s2, substrate treatment; s3, mounting a construction template; s4, pouring coal-fired slag-based foam light soil; s5, laying a galvanized wire mesh; s6, laying anti-seepage geotechnical cloth; and S7, maintaining. The method has the effect of reducing the cracking probability of the roadbed.
本申请涉及路基施工材料和施工方法领域，具体公开了一种燃煤炉渣基泡沫轻质土路基及其施工方法，一种燃煤炉渣基泡沫轻质土路基由燃煤炉渣基泡沫轻质土铺设而成，燃煤炉渣基泡沫轻质土包括煤渣基集料，煤渣基集料包括煤渣基微珠，煤渣基微珠的制备包括以下步骤：冰醋酸溶液中加入生物碳源和煤渣粉，搅拌均匀后滴加到氢氧化钠溶液中，获得凝珠；将凝珠洗涤至中性后冷冻干燥，并在氮气保护下煅烧，获得煤渣基集料。路基施工方法包括以下步骤：S1、开挖路基；S2、基底处理；S3、安装施工模板；S4、浇筑燃煤炉渣基泡沫轻质土；S5、铺设镀锌铁丝网；S6、铺设防渗土工布；S7、养护。本申请具有减小路基开裂概率的效果。
