After decades of practice, contact grouting engineering has formed its inherent construction procedures.
Late grouting hole sealing leakage or leakage may cause serious engineering accident, and affect the safe running of the steel pipe [2]~[3].
In engineering, small initial gap is inevitable existence and is also allowed to exist.
In practical engineering, the method of this paper can be used to simulate analysis of penstock empty under different engineering background, to determine the size of the empty boundaries of the contact grouting.
