Concrete crack control method
The invention relates to the technical field of port construction, and particularly discloses a concrete crack control method which is used for the construction process of a dock breast wall structure, and a breast wall comprises a wall body used for ship berthing and a surface layer needing to bear loads. The method specifically comprises the following steps that a wall body and a surface layer serve as two independent structures and are subjected to reinforcement according to design requirements, and a reinforced concrete plate of an upper-lower-layer reinforcement structure is actually formed on a breast wall; a template is built on the foundation; watering to wet the template and the reinforcing steel bars, and starting to pour concrete after the water on the template and the reinforcing steel bars is fully dispersed; layered pouring is carried out, and secondary vibration is carried out when a surface layer is poured; screeding operation is carried out before initial setting of the concrete; the expansion joint is constructed and filled with an expansion joint filling material; and curing the concrete. According to the concrete crack control method, cracks can be effectively reduced, and the structural strength of the breast wall is improved.
本发明涉及港口施工技术领域，具体公开了一种混凝土裂缝控制方法，用于码头胸墙结构的施工过程，所述胸墙包含用于船舶停靠的墙身、以及需要承受载荷的面层，具体包括如下步骤：将墙身和面层作为两项独立结构并根据设计要求分别配筋，使胸墙实际形成上下层配筋结构的钢筋混凝土板；在该基础上搭建模板；浇水润湿模板和钢筋，并在模板和钢筋上的明水充分流散后开始浇筑混凝土；分层浇筑并在浇筑面层时进行二次振捣；混凝土初凝前进行抹平作业；伸缩缝施工并填入伸缩缝填充材料；养护混凝土。本发明提出的混凝土裂缝控制方法能够有效减少裂缝裂纹的产生，提升胸墙的结构强度。
