简述了氰凝的结构和反应原理。氰凝被灌到地下或含水的混凝土中时 ,迅速与水反应 ,形成不溶于水、不透水体型结构的凝胶体 ,并且体积膨胀 6～ 9倍 ,形成二次渗透 ,达到堵水、补强的作用。通过试验 ,分析了氰凝浆液的物理性质和化学性能 ,为浆液配制提供了依据。工程实例表明 ,采用氰凝灌浆处理 ,可取得良好的效果 The structure and reaction principle of cyanide condensation are briefly described. Cyanide condensate is poured into the ground or water-containing concrete, the rapid reaction with water to form a water-insoluble, impermeable body structure gel body, and the volume expansion of 6 to 9 times, the formation of secondary infiltration, to plug the water, fill Strong effect. Through experiments, the physical and chemical properties of cyanide slurry were analyzed, which provided the basis for the preparation of slurry. Engineering examples show that the use of cyanidation grouting treatment, can achieve good results
