Anchor rod main use and composition of the anchor must have factorsTwist anchor rod is mainly used in mine roadway, railroad, slope and tunnel projects, the main reinforcement of the dam, its role is mainly to ensure the stability of the mine roadway and underground engineering surrounding rock.

Common sense maintenance of right-handed equal-strength threaded anchorsTo introduce you to the maintenance of right-handed equal-strength threaded anchors: Mining anchors have irreplaceable advantages compared with traditional metal anchors.

The role of contemporary anchorMining anchor is the basic component of tunnel support in contemporary coal mines, which reinforces the surrounding rock of the tunnel together and makes the surrounding rock 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.

Factors affecting the quality of anchor tray determinations(1) Environmental temperature change, due to thermal expansion, the balance of the unequal arm and other reasons, will make the balance of the zero point and the equilibrium point of change, the value of the occasional deviation can be up to a number of times the balance of the sensibility. Thus, the balance room should be a constant temperature, first-class, second-class standard balance and first and second-class laboratory balance should be 20 ℃ ± 2 ℃ under the conditions of work, the accuracy of a little lower to reach 20 ℃ ± 5 ℃.

Principle analysis of the collapse reduction effect of left-handed anchorsIf the unstable rock layer of the vault is regarded as the combined beam (plate) supported by the side wall, because the anchor hanging on the stable surrounding rock can be regarded as the fulcrum, the installation of left-handed anchor without longitudinal ribs is equivalent to adding the fulcrum, reducing the support span, and then reducing the bending stress and deflection of the support to maintain the stability of the support and the rock, so that the rock is not easy to deform and damage.
