Construction method adopting inner support for box culvert splayed wall body
The invention discloses a construction method adopting an inner support for a box culvert splayed wall body. The construction method comprises the following steps that a ground anchor structure is pre-buried in a concrete ground; a steel pipe inner support is erected on the concrete ground on site, and the outer contour size of the steel pipe inner support is the same as the size of the box culvert splayed wall body; outer side wood formworks are arranged on the four outer side wall faces of the steel pipe inner support in an attached mode respectively, and the outer side wood formworks on the two opposite side wall faces are fastened through threaded pull rods. And concrete is poured into a cavity defined by the outer side wood formworks so that a box culvert splayed wall body can be constructed and formed. The method has the advantages that the appearance effect of the molded concrete surface is good, and the safety is better; compared with artificial slurry rubble, the comprehensive cost of engineering can be directly saved, the construction period is shortened by 75%, and concrete can be poured after construction is conducted for one day; compared with a wall body bound with a reinforcement cage, the steel pipe inner support is low in cost, and the outline of the wall body can be directly welded to support the formwork.
本发明公开了一种箱涵八字墙墙身采用内支撑的施工方法，包括以下步骤：在混凝土地面中预埋地锚结构；在混凝土地面上现场搭设钢管内支撑，钢管内支撑外轮廓尺寸与箱涵八字墙墙身的尺寸相同；在钢管内支撑的四个外侧壁面上分别贴靠设置外侧木模板，且相对的两个侧壁面上的外侧木模板通过螺纹拉杆实现紧固；向由外侧木模板所围合的腔体中浇筑混凝土，以施作形成箱涵八字墙墙身。本发明的优点是：模后混凝土表面外观效果好、安全性较好；与人工浆砌块石相比，能直接节省工程综合费用，缩短75%施工周期，施工一天即可浇筑混凝土；相较于绑扎钢筋笼墙身，钢管内支撑不仅成本低，并且能直接焊接出墙身轮廓并形成对模板的支撑。
