Rebar Anchor Rod
Rebar Anchor Rod is widely used in coal mine, railway, water and electricity, etc.. The full strength of the whole length of the anchor bolt is 40% higher than that of the same specification bolt, and the use range of the bolt is enlarged, and the end anchor, the lengthened anchor and the full anchor can be realized, and the operation is simple and the price is low.
ADVANTAGES of Underground Mining Tunnel High Strength Rock Anchor Bolt:
1, easy and similar operation principle for different rockmass and soil conditions
2, drilling, anchoring and grouting can be performed in one single operation
3, no pre-drilling of a borehole by using a casing tube and extension rods with subsequent anchor installation necessary
4, minor space requirement for the accomplishment of anchoring
5, optimized machinery and manpower requirements
6, basic dimensioning of the required anchoring forces by choosing the appropriate anchor type
7, optimum bonding of the profiled anchor rod and the grout
8, adjustment of the drill bit design and diameter to different rock mass and ground conditions
9, simple anti-corrosion method available
10, appropriate for temporary or permanent applications
Applicable conditions of Rebar Anchor Rod
1.according to the requirement of design of bolt holes, drilling with drilling machine, anchor drill or coal electric drill, short bolt length depth ratio 80-100mm.
2. with the pressure tube into the fundus, through compressed air, the hole in the rock powder blowing.
3. The diameter of drilling hole is larger than the diameter of bolt 6-12mm.
4.the use of the drug will be sent to the bottom of the cone, start mixing device for mixing, according to the resin anchor anchor requirements strictly control the mixing time.
5.after curing time, set the tray, tighten nut.
