Construction method for reducing cracking risk of mass concrete structure
The invention discloses a construction method for reducing the cracking risk of a mass concrete structure, and belongs to the field of mass concrete construction.The construction method for reducing the cracking risk of the mass concrete structure comprises the steps that firstly, a first layer of concrete is poured in an installed formwork structure; secondly, chiseling treatment is conducted on a layered pouring interface of the first layer of concrete; thirdly, a high-performance slurry storage anti-crack net-shaped structure layer is laid on the layered pouring interface of the first layer of concrete; fourthly, the layered pouring interface of the first layer of concrete and the surface of the high-performance slurry storage anti-crack net-shaped structure layer are wetted with water, and a mortar buffer layer is laid in the high-performance slurry storage anti-crack net-shaped structure layer; and fifthly, a second concrete structure layer is poured on the high-performance mortar storage anti-crack net-shaped structure layer filled with mortar. According to the construction method, the temperature stress borne by the mass concrete structure in the cooling process can be reduced, and the cracking risk of the mass concrete structure is reduced.
本发明公开了一种降低大体积混凝土结构开裂风险的施工方法，属于大体积混凝土施工领域，本降低大体积混凝土结构开裂风险的施工方法包括步骤一：在安装好的模板结构中浇筑第一层混凝土；步骤二：对第一层混凝土分层浇筑界面进行凿毛处理；步骤三：在第一层混凝土的分层浇筑界面铺设高性能储浆抗裂网状结构层；步骤四：用水润湿第一层混凝土的分层浇筑界面及高性能储浆抗裂网状结构层表面，在高性能储浆抗裂网状结构层内铺设砂浆缓冲层；步骤五：在充满砂浆高性能储浆抗裂网状结构层上浇筑第二层混凝土结构层。该施工方法能够降低大体积混凝土结构在降温过程中受到的温度应力，减小大体积混凝土结构的开裂风险。
