Treatment method for annularly continuous bead-like karst caves of tunnel

The invention provides a treatment method for annularly continuous bead-like karst caves of a tunnel. The method comprises steps of execution of emergency treatment measures, primary support treatment of vault caves, primary support treatment of left-skewback caves and primary support treatment of right-hance caves. The treatment method for the annularly continuous bead-like caves of the tunnel is safe, reliable, scientific, feasible, convenient to construct, economical and reasonable, solves the technical problems in construction of the bead-like caves while the construction duration is short, provides reference for follow-up similar cave treatment especially treatment of the vault caves, and realizes the effects of saving time and labor and facilitating construction.
