Secondary pouring method for reserved hole of super-thick wall and embedded pouring sleeve adopted by secondary pouring method
The invention provides a super-thick wall reserved hole secondary pouring method and an adopted embedded pouring sleeve, the embedded pouring sleeve is embedded before primary pouring, a hole steel reinforcement framework and a reserved part of a main body steel reinforcement framework are connected and fixed before secondary pouring, and hole wall formworks are installed and reinforced on the inner side and the outer side of a reserved hole respectively; the reserved hole is sprayed with water for wetting, then concrete is poured, cement mortar is adopted for grouting, and finally fine aggregate concrete is adopted for sealing and compacting the upper end opening of the sleeve body, so that the secondary pouring hole structure is obtained, the forming appearance quality of the secondary pouring hole structure can be controlled, and the forming quality of the secondary pouring hole structure is improved. And moreover, the concrete raw material and the construction cost are saved, interlayer cracks formed after drying shrinkage of the secondary pouring hole opening structure and the primary pouring main body structure of the super-thick wall are avoided, the structural safety such as the adhesion of the primary pouring main body structure and the secondary pouring hole opening structure is enhanced, the construction time is greatly saved, and the engineering quality level is improved.
本发明提供一种超厚墙体预留洞口二次浇筑方法及所采用的预埋浇筑套管，在一次浇筑前埋设预埋浇筑套管，二次浇筑前将洞口钢筋骨架与主体钢筋骨架的预留部分相连接且固定，并在预留洞口的里外两侧分别安装并加固洞口墙模板，先对预留洞口进行洒水润湿，然后浇筑混凝土，再采用水泥砂浆进行灌浆，最后采用细石混凝土对套管本体的上端口进行封堵密实，从而得到二次浇筑洞口结构，不仅能够控制二次浇筑洞口结构成型观感质量，而且节约了混凝土原材料和施工成本，避免了超厚墙体的二次浇筑洞口结构与一次浇筑主体结构因干缩后形成层间裂缝，增强一次浇筑主体结构与二次浇筑洞口结构的粘接性等结构安全性，大大地节约施工时间，提高了工程质量水平。
