The invention relates to the field of tunnel grouting, in particular to a tunnel information tracing accurate grouting method, which solves the problems of thick reinforcing ring, large number of drilled holes, long construction period and the like of the traditional curtain grouting method adopted in current tunnel grouting. The method comprises the processes of
grout stopping wall building, arrangement of orifice tubes and grouting tubes, measurement of the water burst of a
drill hole, packer test, hole arrangement, drilling operation and grouting, wherein the hole arrangement and the grouting are performed according to the sequence from an advance geological
drill hole to other outer ring holes to an inner ring hole to a working surface stabilizing hole to an access hole to a
pipe-shed hole; and steps such as advance big
pipe-shed construction of a working chamber and working surface stabilization by using a
glass fiber anchor rod are saved. In the invention, a break through is made in the conventional construction philosophy, grouting design and geological change are tightly combined together, a grouting mechanism of 'crack blocking, water reduction, surrounding rock fixation and stratum stabilization' is adopted, the grouting holes are reduced by 30 to 40 percent, grouting quality is improved, the safe and quick construction is guaranteed, major water burst and mud burst accidents are eliminated, and the environment is protected maximally.
