Foam light soil composite roadbed construction method for road extension
The invention provides a foam light soil composite roadbed construction method for road extension, which is characterized by comprising the following steps of excavating steps on an original roadbed so as to form a plurality of steps on one side of the original roadbed, on one side of the arrangement direction of the steps of the original roadbed, conducting protective wall foundation concrete pouring and angle steel stand column pre-burying, building aerated concrete on the protective wall foundation to form a protective wall, laying an anti-seepage geomembrane at a position between the original roadbed and the protective wall, manufacturing foam light soil on site, conducting layered pouring construction in each pouring station in sequence, and after pouring of each layer of foam light soil is completed, covering the surface of each layer of foam light soil with a layer of metal net, and laying an anti-seepage geomembrane on the top surface of the foam light soil. According to the construction method, the foam light soil is used as an extension road material, differential settlement of new and old roadbeds can be reduced, the overall stability of a crude oil roadbed and an extension roadbed is improved, the durability of an extension structure is enhanced, and land resource occupation is reduced.
本发明提供了一种用于道路扩建的泡沫轻质土复合路基施工方法，其特征在于，包括：对原路基进行台阶开挖，以使原路基的一侧形成若干级台阶；在原路基的台阶所设置方向的一侧，进行保护壁基础混凝土浇筑及预埋角钢立柱；在保护壁基础上砌加气混凝土以形成保护壁；在原路基与保护壁之间的位置进行防渗土工膜铺设；现场制作泡沫轻质土并依次在每一个浇筑去中进行分层浇筑施工，每一层泡沫轻质土浇筑完成后，在每一层泡沫轻质土的表面覆盖一层金属网；在泡沫轻质土的顶面铺设防渗土工膜。该施工方法利用泡沫轻质土作为扩建道路材料，能减少新老路基的差异性沉降，提高原油路基与扩建路基的整体稳定性，增强扩建结构的耐久性，减少土地资源占用。
