Deformed Reinforcing Bar-manufacture,factory,supplier from China

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.

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.

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

What is the anchor beam system of anchor rods?At present, in the production mines of various companies in China, some of the mining depth has reached more than 500-1000 meters, and the ground stress, surrounding rock force and deformation are complicated and diverse, a single anchor support can no longer meet the requirements of support for the broken roof plate, composite roof plate, and the roadway with high roof plate pressure, and the anchor beam system, which is composed of the anchor rods and the W-beam steel belt, can effectively control the roof plate, and it can be used in the support

The anchoring force test method of left-handed longitudinal ribless anchorsLeft-handed anchor without longitudinal rib has high strength, reasonable structure, large pre-tensioning force, can automatically adjust the direction of force, increase the binding force on the surrounding rock, and can realize mechanized rapid installation.Advantages of left-handed anchor:High strength anchor, reasonable structure, large preload, can automatically adjust the direction of force, increase the binding force on the surrounding rock, can realize the mechanization of rapid installation.

Pipe seam anchors in the process of usePipe seam anchors may encounter the following common problems in the process of use:1. Sinking or loosening of pipe seam anchors: sinking or loosening of anchors may occur after the anchors are subjected to loads.

Shandong Ruiyu Carries Out Winter Fire DrillIn order to further strengthen the fire safety management and improve the fire safety awareness of the workers, Ruiyu Company organized 12 representatives from each department and workshop on November 18, 2024 to conduct a fire accident emergency treatment drill in the open space on the south side of A workshop.

Background on Hollow AnchorsTo better understand the mechanics involved in load transfer between anchors and mine rock, the Bureau of Mines initiated a program to study the load transfer mechanics of passive, fully grouted hollow anchors. This work was accomplished in support of the Bureau's goal of improving the underground safety of the nation's miners. The first phase of the study was conducted in the laboratory to examine the linear, nonlinear, and time-dependent behavior of anchor rods under varying load conditions.
