为了选择出合适的灌浆材料和灌浆工艺并模拟升船机齿条、螺母柱间隙灌浆的实际情况，分别进行了灌浆工艺试验与原型灌浆试验。灌浆工艺试验对比了3种国产灌浆材料和德国PAGEL灌浆材料，试验结果表明德国PAGEL灌浆材料物理性能指标和力学性能指标优于国产灌浆材料。在原型灌浆试验中，对灌浆设备选型、搅拌时间、模板密封、灌浆方式、灌浆流速参数控制等方面进行了试验研究，优选出适用于三峡升船机齿条、螺母柱接缝灌浆的材料和合适的灌浆工艺。以上试验效果明显，解决了灌浆密封难度大、易堵管等施工难题。

In order to choose the suitable grouting material and grouting process, and simulate the actual situation of clearance grouting of rack and nut column in ship lift, grouting process test and prototype grouting experiment were carried out respectively. Comparing three kinds of domestic grouting material and the German PAGEL grouting material in grouting process test, the experimental results showed that the physical and mechanical property indexes of German PAGEL grouting material were superior to the domestic grouting material. In prototype grouting test, selection of the grouting equipment type, mixing time, templates seal, method of grouting parameters control of grouting flow were researched, and some applicable grouting material and grouting process were selected which were suitable for the rack and nut column joint in Three Gorges Project ship lift. The above test effects were obvious, and solved the construction problems of great difficulty in grouting seal and easy blockage of pipeline, etc.
