Plastic concrete diaphragm wall body joint treatment construction process and application
The invention belongs to the field of hydraulic engineering, and particularly relates to a plastic concrete anti-seepage wall body joint treatment construction process and application, and plastic concrete is poured at anti-seepage wall joints of a construction section I and a construction section II of a poured and formed anti-seepage wall after mechanical secondary hole forming; compared with an existing construction technology, the method that plastic concrete is poured after hole forming is adopted, a construction interface (connecting seam) and slurry existing in an original construction joint can be eliminated, and every two adjacent wall bodies are connected into a whole through the poured plastic concrete; meanwhile, a capillary crystalline material in the plastic concrete has the functions of crack self-healing and migration capillary crystalline, a new construction interface (connecting seam) formed between the poured plastic concrete and the two adjacent wall bodies can be effectively repaired, and the technical bottleneck that leakage is likely to happen to the connecting position of the wall bodies of the anti-seepage wall is broken through.
本发明属于水利工程领域，尤其涉及一种塑性混凝土防渗墙墙体接头处理施工工艺及应用，其在已浇筑成形防渗墙的施工段Ⅰ和施工段Ⅱ的防渗墙接头处，采用机械二次成孔后再灌注塑性混凝土；与既有施工技术比较，运用成孔后再灌注塑性混凝土的方法，可消除原施工连接处存在的施工界面(连接缝)和泥浆，相邻两墙体通过灌注的塑性混凝土连接为一个整体；同时利用塑性混凝土中渗透结晶材料具有裂缝自愈合和迁移渗透结晶的功能，可有效修复灌注的塑性混凝土与相邻两墙体间形成的新的施工界面(连接缝)，突破了防渗墙墙体连接处容易渗漏的技术瓶颈。
