When the ambient temperature is less than 10 degrees Celsius, the temperature sensing controller 606 controls the heating rod 607 to heat the water, keeps the water temperature in the water tank 605 at about 10 degrees Celsius, and heats the water in the water tank 605 to about 40 degrees when receiving the slurry making signal from the PLC controller 5. The feed port 604 and the water inlet 608 are used to transport materials to the slurry pool 601 through the PLC controller 5, and the stirring rod 602 is used to stir and mix the materials. Then, the grouting is injected into the sleeve valve pipe 4 through the grouting pump 7. The grouting amount reaches the requirement of single grouting, or the grouting is stopped when the deformation value of the tunnel for a single grouting reaches the allowable value. Therefore, the operating tunnel 1 can be conveniently maintained, and the efficiency of the maintenance of the operating tunnel 1 can be improved. This implementation specifically solves the problem that the prior art cannot conveniently perform maintenance according to tunnel settlement.
