Concrete construction method for CRTSI double-block ballastless track roadbed slab
The invention relates to the technical field of concrete construction, and particularly relates to a concrete construction method for a CRTSI double-block ballastless track roadbed slab. The method comprises the following steps: S1, carrying out raw material storage management; S2, detecting the water content of the aggregate; S3, inputting concrete mix proportion process parameters; S4, binding roadbed slab reinforcing steel bars and mounting a template; S5, carrying out concrete stirring; S6, detecting concrete performance, and determining whether the concrete performance is qualified or not; S7, wetting a supporting layer and a track block, and pouring concrete; S8, plastering and calendaring for multiple times; S9, spraying a maintenance liquid, and loosening the fishplates and the fasteners; and S10, removing the mold, spraying a curing agent on the two side edges of the roadbed slab concrete, and performing covering curing. The construction method is detailed in step, the quality of concrete construction is effectively guaranteed, and meanwhile the construction efficiency is improved. The method is mainly applied to ballastless track roadbed slab concrete construction.
本发明涉及混凝土施工技术领域，更具体而言，涉及CRTSⅠ双块式无砟轨道道床板混凝土施工方法。包括以下步骤：S1、原材料贮存管理；S2、骨料含水率检测；S3、混凝土配合比工艺参数输入S4、道床板钢筋绑扎和模板安装；S5、混凝土搅拌；S6、混凝土性能进行检测，判断是否合格S7、支承层及轨道块润湿及砼灌注；S8、多次抹面及压光；S9、养护液喷涂，松开鱼尾板和扣件；S10、拆模，对道床板混凝土两侧边喷涂养护剂及覆盖养护。本施工方法步骤详细，有效地保证了混凝土施工的质量，同时还提高了施工效率。本发明主要应用于无砟轨道道床板混凝土施工方面。
