Due to the difference of depth of breast wall in the construction techniques of Zhang′s and Bai′s split grouting,the position of original split dam body is different in these two techniques,which will influence curtain shape of dam body,origination point of split grouting,the movement law of grouting fluid and mechanism of grouting.

New Austrian tunneling method was adopted for the primary support,secondary permanent lining and grouting treatment,and the convergence survey was performed after the primary support.

On the basis of this,a grouting treatment scheme for a wind turbine with larger uneven settlement is put forward along with the expatiations made on both the principle and the key control point of the grouting reinforcement.

The grouting machine is an electromechanical device for offshore constructions, which require high reliability, operative convenience and optimized construction.
