| description | The invention discloses a consolidation grouting construction test method applied to a dam foundation. The consolidation grouting construction test method applied to the dam foundation comprises the steps that firstly, conducting measurement and setting out, wherein water pressing holes and grouting holes are marked on a cover weight concrete area of the dam foundation; secondly, conducting hole drilling operation, wherein the water pressing holes and the grouting holes are drilled; thirdly, flushing the drilled holes, wherein the drilled holes are flushed with pressurized water before a packer permeability test; fourthly, conducting the packer permeability test, wherein the water permeation conditions under different water pressures of rock mass at the positions of each water pressing hole and each grouting hole are obtained; fifthly, conducting grouting, wherein a gradual pressure rising method is adopted to pour cement paste; sixthly, conducting the packer permeability test on eachwater pressing hole; and |
