Zusammenfassung:The utility model discloses a sleeve valve pipe grouting reinforcing system for soil between tunnels. The sleeve valve pipe grouting reinforcing system is characterized by comprising sleeve valve pipes, wherein the sleeve valve pipes are arranged in the soil between the two tunnels and divided into two groups; each group of sleeve valve pipes are distributed radially in a fan-shaped manner; and the two groups of sleeve valve pipes are symmetrical. The sleeve valve pipes are phi 48*3.2mm plastic sleeve valve pipes. Each group of sleeve valve pipes are distributed in ten rows. Grids of the sleeve valve pipes are arranged along an arch part. The circumferential distances between the far ends of the sleeve valve pipes are 0.8m. The sleeve valve pipes are phi 48 hard PVC (polyvinyl chloride) pipes, so that the system can bear the maximum pressure of greater than 3.0Mpa. The sleeve valve pipes are distributed reasonably in the soil between the two tunnels, so that the construction safety of buildings, structures an
