Stratum settlement control method based on shield excavation gap
The invention discloses a stratum settlement control method based on a shield excavation gap. The stratum settlement control method comprises the following steps: step 1, drilling a hole in a shield, forming grouting holes in the middle and in the front part of the shield, injecting pre-prepared materials into the excavation gap in the shield tunneling process, and controlling the strata deformation by a way of filling the shield excavation gap in real time; step 2, forming grouting holes in the middle and the front part of the shield according to the hole formed in the step 1; step 3, in the shield excavation process, injecting the pre-prepared materials in the excavation gap through the grouting holes; step 4, controlling the strata deformation by a way of filling the shield excavation gap in real time.
