为确保三峡工程帷幕灌浆质量，寻求合理的施工技术参数、适宜的灌装材料和施工工艺，在右岸导流明渠底板进行了帷幕灌浆试验，试验灌浆段长715．2延m。试验结果表明，采用小口径高压灌浆方法是可行的，不下栓塞、不洗缝、不待凝，可提高工效。改性水泥的灌注效果优于磨细水泥。 In order to ensure the quality of the curtain grouting of the Three Gorges Project, seek reasonable construction technical parameters, suitable filling materials and construction technology, curtain grouting test was conducted on the bottom of the diversion channel on the right bank. The length of the grouting section in test was 715.2 m. The test results show that the use of small-diameter high-pressure grouting method is feasible, no less than embolization, no washing seam, no coagulation, can improve work efficiency. The perfusion effect of modified cement is better than ground cement.
