Rock bolt support should be carried out according to rock soil survey report for design,
first should measure according to anchorage soil of rock bolt to determine which the soil is
suitable anchorage, second, according to the soil mechanical theory formula to determine the
anchorage length of rock bolt and anchor length,and determine anchor Angle, the number of
layout and arrangement, etc., while according to pit of important grade measuring related
data whether exceeded, such as being reinforced soil top horizontal displacement, etc.
Finally check the waist on the tension side beam tensile stress and to ensure that each item
can meet the requirements.
Self drilling rock bolts are widely used as an efficient anchoring means, for drilling,
grouting and anchoring in tunnel pre-support, slope anchor, mining, roadbed reinforcement
and other projects, and they can work well in narrow space. We also provide accessories of
drilling tools, like anchor bits, coupling, spherical nuts, plates, and stopper.
As the expert in self drilling bolt system field,Sinorock is outstanding.Here We will stated
how to install self drilling bolt in Concrete.
Self drilling bolts are an essential part of concrete construction. These are bolts, placed
in the concrete with the threaded side up. They allow you to secure wall forms or other
portions of the construction onto the concrete foundation slab. It’s important when placing
rock bolts to place them carefully and accurately, since moving them later will be extremely
