邱庄水库溢洪道闸室混凝土裂缝成因主要为结构应力集中，基岩对混凝土约束产生拉应力，施工期间混凝土温控及养护条件差和温度筋配置偏少等．裂缝宽0．1～2mm，长度4～13m之间．灌浆施工运用改性环氧装液，采用单液法灌浆，即按事先已配制成既定组成的桨液进行灌浆．压送浆液的动力为气压法，即使用压缩空气压送浆液，化灌方式为纯压式． The causes of the concrete cracks in Qiangzhuang reservoir spillway sluice are mainly the structural stress concentration, the bedrock tensile stress caused by the concrete constraints, the poor temperature control and curing conditions and the less temperature bar arrangement during the construction. Crack width of 0.1 ~ 2mm, length 4 ~ 13m between. Filling construction using modified epoxy liquid, single-liquid method of grouting, that is prepared according to a predetermined composition of the paddle liquid grouting. Pressure feed slurry for the air pressure method, even if the use of compressed air pressure slurry, irrigation irrigation method is pure pressure.
