Drill hollow bar anchor’s performance testing (also called destructive test or fundamental test) is to checkout designed drill hollow bar anchor’s performance before commencement of anchoring engineering. It aims to confirm drill hollow bar anchor’s ultimate bearing capacity and checkout drill hollow bar anchor’s working performance and safety degree under conditions of surpassing designed tension and approaching ultimate tension.
When finding defects during hollow bar anchor’s designed construction, structure parameter or production process should be adjusted before drill hollow bar anchor is officially used.
Drill hollow bar anchor’s acceptance test is a detectable pull-out test to inspect whether construction drill hollow bar anchor reaches designed requirement or not.
Every stage of drill hollow bar anchor’s construction should be strengthened detection test to ensure good supporting effect and sustain engineering’s safe construction.
