Left-Handed Anchor Applied To Mine Roadway And Underground Engineering Perimeter Rock Support
Left-handed anchor applied to mine roadway and underground engineering perimeter rock support
Mining Anchor is a kind of tool applied in mine tunnel and underground engineering perimeter rock support, which can ensure the stability of mine tunnel and underground engineering perimeter rock.
Left-handed anchor rod is applied to mine roadway and underground engineering perimeter rock support, which can ensure the stability of mine roadway and underground engineering perimeter rock. Its structural features: there are rolled continuous threads on the length of the rod body, and the fastening end is equipped with pre-stressing spacer and ball-shaped nut. It is superior to round steel processed anchor rods.
Anchor rod is the basic component of tunnel support in contemporary coal mines, he will be the roadway rock reinforcement together, so that the surrounding rock itself to support itself. Nowadays, anchors are not only used in mines, but also used in engineering technology to reinforce the main body of slopes, tunnels and dams. As a tensile member deep into the ground, the anchor rod is connected with engineering structures at one end and deep into the ground at the other end. The whole anchor rod is divided into free section and anchoring section, the free section refers to the area where the tensile force at the head of the anchor rod is transmitted to the anchored solid, and its function is to apply prestressing force to the anchor rod.
Left-handed anchor high strength, reasonable structure, pre-tensioning force, can automatically adjust the direction of force, increase the binding force on the surrounding rock, can realize the mechanization of rapid installation of left-handed anchor Advantages: anchor high strength, reasonable structure, pre-tensioning force, can automatically adjust the direction of force, increase the binding force on the surrounding rock, can realize the mechanization of rapid installation of the anchor can be the end of the anchor, lengthening anchors and ** anchors, mainly used for the high ground pressure mines with large deformation of roadway It is mainly used for high strength support of large deformation roadway in high pressure mines, and also can be used for high strength and long time roadway support of railroad, hydropower and other kinds of projects.
How to use the left-handed anchor.
1. Determine the anchor hole position according to the design requirements, and drill the hole with drilling equipment.
2.Blow out the rock dust in the hole with pressurized air.
3. Send the anchoring agent to the bottom of the hole, hold it with the anchor rod and start mixing (mixing time according to the type of anchoring agent), after mixing, unload the mixing device, after reaching the waiting time, unload the mixing connector, install the anchor plate, ball washer, friction washer, and tighten the nut with the special wrench.
