摘要
总结甘肃湟水白川水电站水工建筑物化学灌浆防渗堵漏处理经验,重点介绍针对变形缝、施工缝、不同材质结合面以及有压蜗壳流道等渗漏部位,采用聚氨酯类等不同化学材料进行化学灌浆的方法、工艺及效果。
The authors summarize the experience in chemical grouting for the hydraulic structures of Baichuan Hydropower Station which is located on Huangshui River in Gansu Province. For various leak positions such as deformation joints, construction joints, connection surface between different materials and pressure spiral case, differ- ent polyurethane chemical grouting materials were adopted. An introduction was made on the grouting methods, technique and effects.
