Borehole diameter of anchor rods is related to soil conditionsWhat is the typical drilling diameter of anchor rods?Anchor bar is a common foundation reinforcement material used in construction projects. It is made by pre-burying steel bars in the soil, and then pre-stressing and mechanically drilling them, so that the steel bars are tightly bonded with the soil, thus the strength of the soil and foundation can be improved.

Comparison of left-handed anchors with other anchorsLeft-handed anchor is a kind of engineering structure used to support tunnels and rock bodies. Left-handed anchors are easy to make and transport, simple to construct, and can greatly improve the quality and safety of the project. This technology has been widely used in tunnel construction and coal mine support and other fields.Second, the structure of left-handed anchorLeft-hand anchor consists of steel bar, bundle rib and self-locking nut.

Difference between pipe seam anchors and ordinary anchorsPipe seam anchors and ordinary anchors differ in structure, construction and application. Pipe seam anchors are mainly composed of anchor rods, anchor tubes and endurance tubes. The anchor rods are made with smooth surfaces and slits are cut in the anchor tubes, while the structure of ordinary anchors is more diversified.

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.

33mm Split Tube Seam Anchor AdvantagesAs a kind of rock support equipment used in underground mining and civil engineering projects, 33 mm pipe seam anchor shows many advantages in engineering practice. First of all, its high load-bearing capacity is one of the main features of this anchor.

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 ℃.

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.

Difference between left-handed anchor and right-handed anchorCharacteristics of left-hand anchor:Left-hand threaded steel anchor without longitudinal rib resin anchor anchor high strength, reasonable structure, preload, can automatically adjust the direction of force, increase the binding force on the surrounding rock, can realize the mechanization of rapid installation of the left-hand anchor Advantages of left-hand anchors:High strength of the anchor, reasonable structure, preload, can automatically adjust the direction of force, increase the binding force on the surrounding rock, can realiz
