Preparation method of prefabricated foam fiber self-repairing concrete public pipeline cover plate
The invention provides a preparation method of a prefabricated foam fiber self-repairing concrete public pipeline cover plate. The preparation method comprises the following steps that 10) a steel formwork is prepared according to the preset size; 20) a cover plate steel reinforcement framework is built in the steel formwork; 40) foam fiber self-repairing concrete is poured into the steel formwork and vibrated to be uniform; and 50) the steel formwork is dismantled after pouring forming, and the prefabricated foam fiber self-repairing concrete public pipeline cover plate is obtained after natural curing. The cover plate prepared by the preparation method disclosed by the invention is light in weight, does not need to be matched with heavy machinery during construction and can be completed by a small amount of manpower. The cover plate is of a porous structure and is good in water permeability, water can be rapidly drained when the rainfall is suddenly increased, and urban flood disasters are reduced. The cover plate can be pre-prepared before construction, and during construction, the cover plate can be spliced and paved on a pipeline along the length direction of the pipeline, so that the construction is convenient. When the pipeline is maintained, only one piece of cover plate needs to be smashed or pried open, the other pieces of the cover plates can be uncovered in sequence, and the whole road surface does not need to be damaged.
本发明提供一种预制泡沫纤维自修复混凝土公共管道盖板的制备方法，包括以下步骤：步骤10)根据预设尺寸制备得到钢模板；步骤20)在钢模板中搭建盖板钢筋骨架；步骤40)将泡沫纤维自修复混凝土倒入钢模板中，并振捣均匀；步骤50)浇筑成型后拆除钢模板，自然养护后得到预制泡沫纤维自修复混凝土公共管道盖板。本发明制备方法制备得到的盖板轻质，施工时无需重型机械配合，少量人力即可完成。盖板具有多孔结构，透水性好，在降雨量骤增时，可快速排水，减少城市洪涝灾害的发生。可以在施工前预制得到，施工时沿管道长度方向拼接铺设在管道上，施工方便。维修管道时，只需砸开或撬开一块盖板，即可将其余盖板依次揭开，不需要破坏整个路面。
