Embodiment Construction
[0026] refer to figure 1 , figure 2 , image 3 and Figure 4 , the present invention is a soil reinforcement method for realizing the normal pressure opening of a shield machine, characterized in that:
[0027] Include the following steps:
[0028] 1. Stop the excavation of the shield machine, empty the muck in the soil compartment 2 of the shield machine, and seal the soil compartment 2 while discharging soil, and inflate and pressurize the soil compartment 2;
[0029] 1. After the soil discharge in the soil compartment 2 is completed, pour the mixed slurry into the soil compartment 2, and exhaust the soil compartment 2 at the same time until the soil compartment 2 is filled with the mixed slurry;
[0030] , Release the gas pressure in the soil cabin 2, and at the same time replenish the mixed slurry in the soil cabin 2 until the predetermined pressure is reached;
[0031] 1. After the mixed grout is solidified, the soil reinforcement is completed.
