The invention discloses a mass concrete layered pouring construction method for large-scale engineering construction, which is characterized by comprising the following steps of: (1) building a concrete template, cleaning garbage and soil in the template by using a dry brush and a suction mode, and wiping oil stains on the surface of a reinforcing steel bar by using a wet brush; and (2) discharging the stirred concrete from a material opening. The vibrating device has the beneficial effects that vibrated concrete adhered to the outer surface of the vibrating rod is rapidly cleaned and is vertically inserted into a non-vibrated concrete area again, so that the transmission effect of vibrating vibration can be ensured, the vibrating effect is ensured, the concrete is vibrated compactly, water is fully mixed, and excessive water seepage of the concrete is prevented; the vibrating rod is rapidly and vertically inserted and slowly lifted, the inserting and vibrating time is manually controlled, the vibrating method is scientific and reasonable, concrete is vibrated in sequence, the concrete vibrating effect is further guaranteed, and water seepage is further reduced.
本发明公开了一种大型工程施工用大体积混凝土分层浇筑施工方法，其特征在于，步骤如下：(1)、搭建好混凝土模板，并对模板内的垃圾和泥土用干刷和吸除方式清理干净，并把钢筋表面的油污用湿刷擦除；(2)、把搅拌好的混凝土从料口下料。本发明的有益效果为：对振捣棒的外表面粘附的已振捣过的混凝土进行快速清理，并再次垂直插入未振捣的混凝土区域，这样能够保证振捣震动的传递效果，从而保证振捣效果，使混凝土振捣密实，水分充分混合，防止混凝土过多沁水；以快速垂直插入振捣棒并慢速提起振捣棒，并人工控制插入振捣时间，振捣方法科学合理，并按顺序对混凝土进行振捣，进一步保证了混凝土振捣效果，进一步减少沁水。
