The well-known advantages of self-drilling rock anchor

As an advanced new type of self-drilling anchor,it has been significantly involved in transportations,water energy,roadway project,highway project,raiway station,hydroelectric support project,mining,tunneling,civil construction and slope stabilization.With this,the advantages of rock anchor can be clearly seen,like efficient,convenient installation,practical,economical,safe in the whole process of geological engineerings.

1.Self-drilling rock anchor can be applied in foundation project to take place of underground continuous retaining wall and micro-bolting.The application of various gravity retaining wall can not only save the consumption of equipment materials greatlt but also was able to reduce the construction cycle,promote efficiency,reduce labor strength,except that,the safty factor of high-stress self-drilling rock anchor can be greated increased.

2.Self-drilling anchor system can be applied in the foundation support of railway and roadway,micro-bolting can largely increase the service life of roadway as well as railway to guarantee civil happiness in their trips and working.

3.Self-drilling anchor is often used in the forepoling of tunnel to take place of conventional bolting method,while,traditional pipe tubing and smaller one are kind of steel bar and full of groutable boreholes around its full length,in addition,common hollow bar should be cased and grouted in advance in order to shrink the cycle of operation.And,sel-drilling bolt feasures drilling,grouting,anchoring for simultaneous construction.
