Cast-in-place concrete small-section box culvert one-time forming method
The invention relates to the technical field of engineering construction, and in particular relates to a cast-in-place concrete small-section box culvert one-time forming method. The method comprises the steps of cushion layer pouring, bottom plate, side wall and top plate steel bar binding, formwork erecting, concrete pouring, curing and formwork dismantling. A base cushion is poured with C20 concrete, after the cushion solidifies to meet the design requirements, steel bars of a bottom plate, side walls and a top plate are bound, an aluminum alloy formwork is adopted as the formwork, on-site splicing is carried out, the lower end of the formwork is fixed to the cushion which is already poured through expansion bolts, concrete pouring is carried out after formwork erecting is completed, the bottom plate and part of the side walls are poured firstly, then the remaining side walls are poured, and finally the top plate is poured; after pouring is completed, thin film covering is adopted in time, and maintenance is conducted; and the formwork is removed after the concrete strength meets the design requirements. The construction method of one-time pouring forming is adopted, the construction period is shortened, and the engineering defects of construction joint reserving, no joint, slab staggering and the like are overcome.
本发明涉及工程建筑技术领域，具体涉及一种现浇混凝土小截面箱涵一次成型方法，包括：垫层浇筑，底板、侧墙、顶板钢筋绑扎，模板支设，混凝土浇筑，养护，模板拆除，基底垫层采用C20混凝土浇筑，垫层凝固达到设计要求后，进行底板、侧墙及顶板钢筋的绑扎，模板采用铝合金模板，现场拼装，模板下端通过膨胀螺栓与已经浇筑完成的垫层固定，模板支设完成后进行混凝土浇筑，先浇筑底板和部分侧墙，再浇筑剩余侧墙，最后浇筑顶板；浇筑完成后及时采用薄膜覆盖并进行养护；混凝土强度达到设计要求后进行模板拆除。本发明采用一次浇筑成型的施工方法，缩短了施工工期，避免了施工缝的留设，无接缝、错台等工程缺陷。
