化学灌浆采用硅酸钠或高分子化合物溶液作为浆液的灌浆工程。它可解决水泥灌浆难以奏效的特殊工程地质问题，大多在水泥灌浆完成后，用于局部孔段的补强灌浆。粉细砂层和有细微裂缝的混凝土也常用化学灌浆进行防渗处理或补强加固。化学灌浆的主要优点：①化学溶液的粘度低，可灌性好，能灌入0.03～0.001mm的微细裂隙中,还能渗入泥化夹层中，并改变其物理力学性能。②化学溶液从流体变成胶凝体或固体的聚合时间，可在几秒钟到数小时之间较准确地进行控制，有效地控制浆液扩散范围，还可在很短的时间内封堵有压集中渗流。③其聚合体几乎是不透水的,渗透系数一般为10-8cm/s，且在高水头下不易被挤出。但它也有缺点，主要是：①大多数化学浆材价格昂贵；②除硅酸钠外，所有的高分子化学浆材都有不同程度的毒性，施工时须采取严格的密封措施，以保护操作人员的健康，并防止污染环境；③聚合物的老化与耐久性，经短期观测证明情况尚好，但缺少长期的观测资料。化学浆材种类很多，通常以其主剂名称命名。常用于地基防渗处理的有:硅酸钠(Na2SiO3)系、丙凝（主剂为丙烯酰胺）、聚氨酯（分水溶性与油溶性两种，主剂为甲苯二异氰酸酯）。常用于建筑物补强加固的有：甲凝（主剂为甲基丙烯酸甲酯）、环氧树脂、聚氨酯等。化学灌浆开始前都要进行现场灌浆试验。其施工程序为钻孔、冲洗、压水试验、配浆、灌浆。灌浆方法有两种：①单液法,将浆液的各组分在灌浆前一次配成,用灌浆泵压送到钻孔内；②双液法，将预先制成的两种浆液分别盛于各自的容器内，使用比例泵按规定比例送浆，使两液在孔内充分混合，进入裂隙内完成聚合反应。常用的化学灌浆泵有：手摇压浆泵、双液化灌计量泵（比例泵）、可控硅调速齿轮泵、隔膜计量泵等。参考书目刘嘉材著：《化学灌浆》（水利水电施工丛书），水利电力出版社，北京，1988。
