Consolidation grouting hole layout

Consolidation grouting hole layout often used in the form of square, plum and hexagonal, and some use diamond or other forms. The main advantage of square hole distribution is that it is easy to add grouting holes, which is often used in areas with complex geological conditions, broken rocks and multiple fissures. The main disadvantage of the plum blossom hole is that it is not convenient to add the grouting hole, so in the geological conditions are better, it is expected that after the grouting does not need to add the grouting hole area to use this form.
