Narrow roadway high-precision super-flat floor construction method

The invention discloses a narrow roadway high-precision super-flat floor construction method. The method comprises the steps that a warehouse bottom plate of a concrete structure is completed and passes acceptance inspection; a vapor-proof film and a heat preservation layer are laid on the warehouse bottom plate; warehouse division is carried out, then a warehouse lattice concrete formwork is erected, and reinforcing steel bars are bound; the elevation of a guide beam is adjusted; concrete is poured and vibrated; the elevation of the guide beam is rechecked; the concrete is roughly slicked; the concrete surface is finely slicked; carborundum is uniformly spread on the concrete surface layer by using spreading equipment; the surface layer is polished; and a curing agent is scatted and polishing is carried out, and therefore, the flatness of a narrow roadway floor is effectively ensured. 本发明公开了一种窄巷道高精度超平地坪施工方法，包括：完成混凝土结构的仓库底板并验收通过；在仓库底板上进行隔汽膜和保温层铺设；分仓，然后支立仓格混凝土模板和钢筋绑扎；导梁标高调整；混凝土浇筑和振捣；导梁标高复核；混凝土粗刮平；混凝土面精细刮平；在混凝土
