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.

A mining anchor is a support device used to reinforce a mine tunnel or underground engineering structure, usually made of high-strength steel.

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.

Shandong anchor construction characteristics1. Shandong anchor positioning lineFirst according to the design drawings with a latitude and longitude meter measured and released the construction area of the anti-floating anchor hole position, with wooden stakes or steel bars for marking and numbering. Allowable deviation of anchor hole position is not more than 50mm.2. Rig in placeAfter measuring and releasing the anchor holes, the drilling rig can be put into position.
