尼尔基水利枢纽右副坝坝基底部存在一透水层,由于坝基地质条件复杂,有个别地段不透水层厚度较薄,故需在透水层上进行粘土心墙填筑,再进行高压摆喷灌浆。为此,进行了粘土心墙内高压摆喷灌浆试验,以确定施工参数。从试验结果看,成墙效果良好,解决了非原状土层上高压喷射灌浆的技术问题。 Due to the complex geological conditions in the dam base and the thin impermeable layer in some sections, it is necessary to fill clay core walls with water in the permeable layer and carry out high-pressure swing grouting grouting . To this end, a high pressure swing grouting grouting test was conducted on the clay core wall to determine the construction parameters. From the test results, wall into a good effect, to solve the non-original soil high-pressure jet grouting technical problems.
