Self drilling anchor is a kind of hollow anchor bolts, can be used as drill bar and also grouting pipe. Seriflux, going through hollow anchor bar and ejecting from drill bit, fills cracks and drill holes in surrounding stratum, which makes Self drilling anchor integrate with surrounding soil body and then haves reinforcement effect. So Self drilling anchor is a new supporting technology combining functions of drilling, grouting and anchoring together.
Self drilling anchor also has character of lengthening. So short anchor bar can use small drill machine at narrow environment. Without casing pipe, self drilling anchor is suitable for hole collapse stratum to reinforce existing structure. Nowadays, self drilling anchor is widely used in infrastructure projects, such as slope support of hydropower station and railway tunnel support.
