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.

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 ℃.

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.

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.

Application of Mining AnchorMining anchor rod is a tool applied to support the surrounding rock of mine roadway and underground project, which can ensure the stability of the surrounding rock of mine roadway and underground project.Mining anchor rod use scope, can realize end anchor, lengthening anchor and ** anchor; easy to operate, low price and other advantages, widely used in coal mines, railroads, hydropower and other projects all kinds of roadway support.Anchor is the basic component of tunnel support in contemporary coal mines, he will be the roadway rock reinforcement together, so that

Shandong Ruiyu Carries Out Road Traffic Safety LectureIn order to improve the staff's self-safety awareness, to prevent road traffic accidents on the way to and from work, to enable employees to master the reasonable disposal methods after traffic accidents, and to minimize the losses, Ruiyu Company, taking the opportunity of learning and implementing the new “Work Safety Law”, invited the Traffic Police Battalion Accident Handling, Insurance Company Claims, Buick 4S Store Vehicle Maintenance and other relevant professionals to the company on Oct.

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.

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.
