Consolidation grouting construction test method applied to dam foundation |
| abstract |
The invention discloses a construction test method for consolidation grouting applied to a dam foundation, comprising: step 1, measuring and setting out, and calibrating a water press hole and a grouting hole on the weighted concrete area of the dam foundation; step 2, drilling Drilling operation, drilling the water press holes and the grouting holes; step 3, drilling flushing, flushing the drilled holes with pressurized water before pressing water; The water permeability of the rock mass at the hole and the grouting hole under different water pressures; Step 5, the grouting adopts the step-up pressure method to carry out cement slurry injection; Step 6: Carry out a water pressure test on the water pressure hole; Step 7 : Seal the grouting hole. The construction test method of the present invention can perform the consolidation grouting test more conveniently by configuring the relative positions of the water-pressing holes and the grouting holes, and the steps of performing the water-pressing test and the cement slurry pouring on the water-pressing holes and the grouting holes. Obtain infiltration data to provide a basis for strengthening the dam foundation and maintaining the stability of the dam. |
