葛洲坝一期工程从1970年初开始施工,到1981年6月已基本建成,完成了十个单项主体工程建筑物。为保证上述建筑物的安全稳定,防止基础出现超过设计允许的扬压力和软弱夹层产生渗透破坏,减少基础渗流,我们按照设计要求,于1976年9月～1981年6月进行了大规模的帷幕灌浆施工,完成的工程量为:防渗轴线全长2806.86米,钻孔合计1966个,总进尺36196.79米,钻孔6451段。灌浆合计2818段,总深度11477.1米,灌入丙凝37569.98升,水泥302.3吨。 The construction of the first phase of Gezhouba Project started from the beginning of 1970, and basically completed in June 1981, completing 10 individual main engineering buildings. In order to ensure the safety and stability of the above buildings and to prevent infiltration and destruction of the foundation beyond the design allowable uplift pressure and weak interlayer, and to reduce the foundation seepage, we conducted a large-scale curtain curtain from September 1976 to June 1981 in accordance with the design requirements Grouting construction, the completion of the project volume: seepage axis length of 2806.86 meters, a total of 1966 drilling holes, the total footage 36196.79 meters, drilling 6451 segments. A total of 2818 sections of grouting, the total depth of 11477.1 meters, poured into the condensate 37569.98 liters, 302.3 tons of cement.
