As supporting engineering product, self drilling rock bolt plays an important role in the safety of the project, at the beginning of the project design, the selection of self drilling rock bolt is especially important, according to the actual geological conditions and the number of years of engineering, select the appropriate safety factor is to find the balance between security and investment, following the selection of self drilling rock bolt safety principles and standards of each country making a simple comparison.
With the complicated geological structure, there exists the possibility of disaster,which brings very great difficulty in self drilling rock bolt for support.So give you some tips about making control scheme of self drilling rock bolt supporting, First,the self drilling anchor bar supporting structure must have a good ductility, you have to maintain stability of the self drilling rock bolt supporting system. Second, the instability of deep underground is the concrete performance of damage of rock mass , you should have the function of the self drilling rock bolt supporting system under the condition of static instability routine. http://selfdrillingbar.drupalgardens.com/content/hollow-anchor-bar-sinorock-efficient-anchoring-method お気に入りの記事を「いいね!」で応援しよう
