Background technology
In shield tunneling process, grouting behind shaft or drift lining mainly solves the problems, such as following：
(1) stratum deformation is controlled.Since the digging diameter of cutter head of shield machine is more than section of jurisdiction outer diameter, pipe sheet assembling finishes abjection
After shield tail, an annular gap, abbreviation gap of the shield tail are formed between the soil body.If gap of the shield tail cannot be filled in time, gesture
Stratum deformation must be caused, adjacent earth's surface building, structure sedimentation or tunnel is made to generate offset in itself.Grouting at the tail of the shield machine it is most heavy
Syllabus is exactly timely filling gap of the shield tail, prevents from causing stratum that larger deformation occurs because of the presence of gap of the shield tail.
(2) impermeability in tunnel is improved.After grouting at the tail of the shield machine solidification, generally there is anti-permeability performance, it can be as the first of tunnel
Road water-proof wire, so as to improve the anti-permeability performance in tunnel.
(3) slurries for possessing certain early strength fill gap of the shield tail in time, it can be ensured that the early strength of pipe-plate lining
And stability at later stage.Shield tunnel is the structure of a kind of pipe-plate lining and the coefficient stable structure of country rock, and section of jurisdiction is carried on the back
It uniformly, densely injects, fill the precondition for being to ensure that soil pressure stepless action in face gap.
Therefore, when pipe-plate lining carries out assembled, ensure slurries uniformly, to be densely attached with the soil body be very
Important.
