GMR series self-drilling flexible hollow grouted anchor

タイトルまたは説明

In condition of serious deformation due to high ground stress, it is impossible to support the surrounding rock by normal anchor bar, with the anchor bar being damaged ahead of time, which greatly endangers the construction of project. The above mentioned problem can be solved by type GMR self-drilling flexible anchor bar which releases the stress and ground deformation and controls the random deformation of surrounding rock, realizing the purpose of ground supporting. It avoids the damage of anchor bar due to large deformation and brings into full play of material mechanical performance of anchor bar to a great extent. It is the only anchoring system to support the ground at large deformation zone due to high ground stress at present.
