Description
Technical field
The invention belongs to erosion control support anchor rod fields, and in particular to a kind of to continue resigning erosion control for bump tunnel
Support anchor rod and its setting method.
Technical background
Bump is one of the most serious disaster encountered in coal production.According to 2500 destructions for having record to China
Property bump analysis shows, 90% bump occurs in tunnel.Therefore roadway support is important research topic, anchor
Bar anchoring is the important method of roadway support.The deformation in the tunnel with bump risk is larger, and common anchor pole cannot
This impact large deformation is born, fracture is easy to happen, thus supporting cannot be played.And existing anchor pole is all to have admittedly
Fixed length, for the anchor pole with regular length, if the rock-bolt length reserved is too long to will lead to lane space deficiency, too
It is short to resist impact large deformation, do not have the effect of supporting.
Summary of the invention
For the above technical problems, the present invention, which provides, a kind of continues resigning erosion control branch for bump tunnel
