Embodiment Construction
[0036] Below in conjunction with accompanying drawing and embodiment the technical solution of the present invention is further described:
[0037] like figure 1 As shown, the compaction grouting method in the present embodiment comprises the following steps:
[0038] 1) Drill grouting holes on the standard block of the ring segment 1, the grouting holes include the first group of grouting holes 2, the second group of grouting holes 3 and the third group of grouting holes distributed sequentially from bottom to top 4. Taking the plane passing through the center axis of the tunnel and the center line of the rail as the reference plane, the first group of grouting holes 2, the second group of grouting holes 3 and the third group of grouting holes 4 each include two reference planes It is called distributed grouting holes. It should be pointed out that during the process of drilling grouting holes, the distribution of steel bars under the ground needs to be surveyed, and the pos...
