Lightweight material treatment construction method for viaduct head roadbed
The invention discloses a light material treatment construction method for a viaduct head roadbed. The light material treatment construction method comprises the following steps that S1, light materials are selected, wherein light soil foam with the density being 30-50 Kg/m < 3 > and the foaming ratio being 800-1200 is selected; s2, preparation of cement slurry: stirring water and cement to obtain slurry; s3, mixing of the light material and the cement paste, wherein the light material and the pressurized cement paste are mixed, and parameters of the light material and the pressurized cement paste are adjusted in the construction process; s4, formworks are installed, specifically, the formworks are sequentially installed and disassembled in a layered mode according to a construction cross-section diagram and a foam light soil extension roadbed design list; and S5, pouring construction is conducted, specifically, layered pouring is adopted, and when the area exceeds a preset numerical value, block pouring needs to be adopted. According to the method, bump at the bridgehead is prevented, and the bridgehead guide roadbed is treated with foam light soil.
本发明公开了一种高架桥头路基轻质材料处理施工方法，包括以下步骤：S1：轻质材料的选择：选择密度为30‑50Kg/m3、发泡倍率800‑1200的轻质土泡沫；S2：水泥浆的配置：将水和水泥进行搅拌得到浆料；S3：轻质材料与水泥浆的混合：将轻质材料和加压水泥浆混合，施工过程中应对其参数进行调整；S4：安装模板：模板安装要按照施工断面图及泡沫轻质土扩建路基设计一览表进行分层依次安装与拆卸；S5：浇筑施工：采用分层浇筑，面积超过预定数值时，还需要采用分块浇筑。本发明，防止桥头跳车，对桥头引路路基采用泡沫轻质土进行处理。
