Soil stabilization structure for railway yard shield tunneling construction

The utility model discloses a soil stabilization structure for the railway yard shield tunneling construction. Grouting holes stretching into the bottom of a rail track obliquely are formed in the two sides of a platform. Double liquid grout contained in a sleeve valve pipe in each grouting hole condenses to form a reinforcing rod and a grout connecting ball outside the reinforcing rod. The grouting holes in each side are quincuncial. The grouting holes in the two sides are arranged in parallel in a staggered mode. Every two adjacent grout connecting balls on the same side are connected. The grout connecting balls on the two sides are connected to form an integrated stereo netty structure, and then a stereo netty reinforcing structure is formed for the soil under the rail track. Therefore, the strength and self-stability of the soil are improved, and the shield tunneling construction is facilitated.
