Self-drilling anchor can simplify construction procedure

is a kind of hollow anchor. It can be drill pipe and grouting pipe as well.
Slurry can spray from the bits to fill in the fractures and drilling holes beside anchors so that the
self-drilling anchors can concrete with the solid together. The reinforcement method of combination
of self-drilling anchor and frameworks for retaining walls is applied in this project.

In this method, the framework was combined with the insufficient strength retaining wall by the
application of self-drilling anchors, the integration of the retaining wall and the stability and
strength of load retaining wall are improved to insure the railway straightway.
Based on the above engineering example, we can find that, the advantages of self-drilling anchors’
unify of drilling, grouting and anchoring can be seen under the condition of loose rocks. Also the
application of self-drilling anchors can prevent the accidents that flagstones caused when strengthen
structures. And self-drilling anchor can simplify construction procedure and improve working
efficiency.
