Hold through after anchor disk and steel mesh, the end of free end is anchored in country rock by resin explosive roll, the nut set below anchor disk is used
In the bottom for fixing anchor disk；Anchor disk, anchor pole, nut and steel mesh constitute prop, the pressure to bear country rock；The anchor disk
Center to lower recess, form depressed part, the center of depressed part is provided with perforation, perforate for anchor pole from centre through fixation
Anchor disk.
The edge of described anchor disk is handled using rounding, and the cross section of anchor plate edge is semicircle, to justify with steel mesh
It is sliding to touch.
Described anchor disk is shaped as square or circle.
Rubber ring is provided between described perforation and anchor pole, to reduce friction.
Compared with prior art, the beneficial effects of the utility model are：
1) the utility model includes anchor disk and anchor pole, and anchor disk and anchor pole are fixed on steel mesh by nut, described anchor disk
Top be equipped with below steel mesh, anchor disk and be provided with nut, the fixation anchor end of anchor pole is located at the top of steel mesh, the freedom of anchor pole
Hold through after anchor disk and steel mesh, the end of free end is anchored in country rock by resin explosive roll, the nut set below anchor disk is used
In the bottom for fixing anchor disk；Anchor disk, anchor pole, nut and steel mesh constitute prop, the pressure to bear country rock, operation side
Just；
2) center of the anchor disk forms depressed part to lower recess, and the center of depressed part is provided with perforation, and perforating is used for
Anchor pole is from centre through fixed anchor disk, and the edge of anchor disk is handled using rounding, and the cross section of anchor plate edge is semicircle, with
It is connected with steel mesh transition, reduces anchor disk to hard friction between steel mesh and concrete spray coating, it is to avoid anchor disk breaks steel mesh, concrete spray
Layer and country rock, reduce tunnel rate in bad repair, extension tunnel and the length of service by prop；
3) anchor disk described in is shaped as square or circle, to adapt to different concrete spray coatings and country rock；
4) rubber ring is provided between perforation and anchor pole, to reduce friction, it is ensured that service life.
