Unribbed Threaded Anchor Rod

Application of Unribbed Threaded Anchor Rod

Longitudinal ribless rebar resin anchors are mainly used for high strength support of large deformation roadways in high pressure mines, including full rocky roadways, coal roadways, semi-coal roadways, and also can be used for high-electricity everlasting roadway support of railroads, highways, hydropower and different forms of tasks.

Product Features of Unribbed Threaded Anchor Rod

This product is a type of anchor made by special processing era, the electricity of the threaded section is more than the strength of the rod frame, and the bending and shear resistance is right, it is a brand new type of anchor for high strength assist in shafts. it's far a new sort of anchor for high power help of shafts. it has reasonable shape, huge preload, can routinely regulate the path of force,increase the binding force on the surrounding rock, and can be mechanized and installed quickly, and can be used as end anchors, extension anchors and full anchors. It is easy to transport, anti-corrosion and anti-rust, and has a wide range of applications.

Product selection and working conditions of Unribbed Threaded Anchor Rod

1, Product choice: assist designers in line with the roadway phase of the encompassing rock geological conditions to discover the surrounding rock to stress parameters, and then mixed with sensible enjoy, can choose different specifications of the anchor.

2、Using working conditions: Users should have drilling and installation equipment, resin anchors and so on. In order to increase the effect of support, after the installation of anchor rods, plus the installation of anchor net anchor cable and slurry. The drilling size and depth should be used according to the specifications of anchor rods and anchoring agents; considering the power conditions of the site, it's miles recommended to prioritize the use of pneumatic anchor drilling rigs or hydraulic anchor drilling rigs in order that the drilling and set up are executed within the same system: for the use of high rock hardness web page choice of the 7655 wind hammer drilling, pneumatic coal drilling and stirring set up.Stirring installation of rated output speed ≥ 400 rpm output torque, for the full-length anchoring should be 2 60Nm; for end anchoring should be 240Nm machine.

Structural features and working principle of Unribbed Threaded Anchor Rod

1, structural features: each set of non-longitudinal aid threaded steel type resin anchor by the metal rod body (rod end of a section of 80 ~ 120mm thread) with a thickened hexagonal nut, an anchor tray.

2, working principle: anchor is anchored in the rock body to maintain the stability of the surrounding rock rod-like structure, in the surrounding rock to play the role of suspension, combination of beams, combination of arches, wedge and so on. In the installation process, the resin anchor metallic rod body plays the function of mixer, the rod frame through the anchor drilling rig rotation into the hole has been punched, will be located earlier of the hollow give up of the resin anchoring agent pounding damaged, in order that the resin cement and curing agent mixed with a chemical reaction, the resin cement is speedy cured, the rock and the anchor rod bonded collectively, to play the role of anchoring. a certain wide variety of anchors are driven within the equal piece of surrounding rock to shape an anchor help system.

Product description of Unribbed Threaded Anchor Rod

The longitudinal ribless threaded steel resin anchor executes mt146.2-2011 preferred. it is a type of anchor made via unique processing technology, the strength of threaded section is extra than the electricity of the rod frame, the threaded phase has true performance of bending and shearing, it's far a new type of anchor for high strength guide of shaft.the anchor has excessive power, affordable shape, big tightening pressure, can automatically adjust the route of pressure, increase the binding force at the rock can recognize the mechanization of speedy set up. it can be used as stop anchor, extension anchor and full anchor, and is specifically used for high electricity support of big deformation roadway in highland pressure mines. utility:coal mine roadway assist, however also can be used for railroads, hydropower and other forms of engineering excessive-strength everlasting roadway assist.

Usage of Unribbed Threaded Anchor Rod:

1. Determine the anchor hole position according to the design requirements and drill the hole with drilling rig.

2. Use the pressurized air pipe to go deep into the bottom of the hole and blow clean the rock dust.

3. send the anchoring agent into the bottom of the hole, set it with the anchor to begin mixing (mixing time is certain in line with the model of the anchoring agent), blending is completed, sell off the integration equipment to attain the ready cooling time, sell off the integration connecting head to install the anchor plate, ball washing machine friction washer, and tighten the nut with a unique wrench.

Anchor characteristics of Unribbed Threaded Anchor Rod:

1. superficially it restricts the rock and soil body from the original body.

2. Macroscopically it increases the cohesion of the rock and soil body.

3. anchor rods are not most effective used in mines, however also used in engineering era for energetic reinforcement of slopes, tunnels, dams and so forth.

4. anchor is the primary thing of tunnel assist in contemporary underground mining, which binds the fringe rock of the tunnel together, in order that the perimeter rock helps itself.
