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 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

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 ℃.

Current application of mining anchorThe original anchor retaining wall construction is completed and in use for a period of time, because in the planning of the unfavorable elements do not  part, the construction process of the construction of the quality of the construction is not controlled or not in accordance with the construction process of construction, in the process of application because of man-made or natural factors, etc.

Shandong Ruiyu Company's Anchor Fixing Agent Automation Production Line Trial Production as ScheduledIn order to solve the problem of supply and demand in anchoring agent market, eliminate backward production capacity, promote process upgrading, and improve the labor environment, Ruiyu anchoring agent automation project was completed in late August with an investment of more than 10 million after a rigorous preliminary research on the equipment, the selection of manufacturers, and the acceptance of the equipment installation, and was successfully put into trial production.The anchoring age

Linkage between pullout force and distance distribution of anchor disk with anchorsGeotechnical anchoring skill is an important part in the field of geotechnical engineering, and it has a wide range of applications in the fields of hydraulic construction, towering structure, underground engineering, anti-slip engineering and slope engineering.

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.

Shandong Ruiyu Company Solidly Carries Out “Safety Production Month” ActivitiesRuiyu Company closely follows the theme of “Strengthening Red Line Awareness and Promoting Safe Development”, increases safety publicity and education, strengthens the awareness of “red line”, and strictly abides by the “bottom line”.

Mining anchor support effectMining 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.

 Ultra-Deep Coal Mining Vertical Shaft To Crack The Support Problem  A few days ago, a group company improved the design of cyclic step of over-head support, which solved the problems of roof crushing caused by repeated support.
