UnribbedThreaded Anchor Rod

Application of UnribbedThreaded Anchor Rod

Longitudinal ribless rebar resin anchors are particularly used for high energy aid of big deformation roadways in excessive stress mines, consisting of full rocky roadways, coal roadways,semi-coal roadways, and can also be used for high-strength permanent roadway support of railroads, highways, hydropower and other types of projects.

Product Features of UnribbedThreaded Anchor Rod

This product is a form of anchor made by means of special processing technology, the power of the threaded section is more than the electricity of the rod frame, and the bending and shear resistance is ideal, it is a brand new form of anchor for excessive power assist in shafts.It is a new type of anchor for high strength support of shafts. It has reasonable structure, large preload, can automatically adjust the direction of force, increase the binding force on the surrounding rock, and can be mechanized and installed quickly, and can be used as stop anchors, extension anchors and complete anchors. it is simple to move, anti-corrosion and anti-rust, and has a huge range of applications.

Product selection and working conditions of UnribbedThreaded Anchor Rod

1, product selection: support designers according to the roadway section of the surrounding rock geological conditions to detect the surrounding rock to pressure parameters, and then combined with realistic enjoy, can pick special specifications of the anchor.

2、The use of working situations: users should have drilling and installation system, resin anchors and so on. which will increase the impact of help, after the installation of anchor rods, plus the installation of anchor internet anchor cable and slurry. the drilling size and intensity should be used in keeping with the specs of anchor rods and anchoring dealers; considering the electricity conditions of the web page, it is recommended to prioritize the use of pneumatic anchor drilling rigs or hydraulic anchor drilling rigs so that the drilling and installation are carried out in the same machine: for the use of high rock hardness site selection of the 7655 wind hammer drilling, pneumatic coal drilling and stirring installation. 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 UnribbedThreaded Anchor Rod

1, Structural capabilities: every set of non-longitudinal useful resource threaded metallic kind resin anchor by using the metallic rod frame (rod cease of a segment of eighty ~ 120mm thread) with a thickened hexagonal nut, an anchor tray.

2, Running precept: anchor is anchored inside the rock body to maintain the stability of the encompassing rock rod-like shape, inside the surrounding rock to play the role of suspension, aggregate of beams, combination of arches,wedge and so on. In the installation process, the resin anchor metal rod body plays the role of mixer, the rod body through the anchor drilling rig rotation into the hole has been punched, will be placed in advance of the hole end of the resin anchoring agent pounding broken, so that the resin cement and curing agent mixed with a chemical reaction, the resin cement is quickly cured, the rock and the anchor rod bonded together, to play the role of anchoring. A certain number of anchors are driven in the same piece of surrounding rock to form an anchor support system.

Product description of UnribbedThreaded Anchor Rod

The longitudinal ribless threaded steel resin anchor executes MT146.2-2011 standard. It is a kind of anchor made by special processing technology, the strength of threaded section is greater than the strength of the rod body, the threaded section has good performance of bending and shearing, it is a new type of anchor for high strength support of shaft.

The anchor has high power, reasonable structure, huge tightening pressure, can mechanically modify the direction of force, increase the binding force on the rock can recognise the mechanization of rapid set up. it may be used as end anchor, extension anchor and full anchor, and is mainly used for high energy aid of large deformation roadway in highland strain mines. utility:coal mine roadway assist, but additionally can be used for railroads, hydropower and other forms of engineering excessive-power permanent roadway assist.

Usage of UnribbedThreaded Anchor Rod:

1. decide the anchor hollow function according to the layout requirements and drill the hole with drilling rig.

2. use the pressurized air pipe to go deep into the lowest of the hole and blow smooth the rock dust.

3. Send the anchoring agent into the bottom of the hole, set it with the anchor to start mixing (mixing time is specified according to the model of the anchoring agent), mixing is finished, unload the mixing apparatus to reach the waiting cooling time, unload the mixing connecting head to install the anchor plate, ball washer friction washer, and tighten the nut with a special wrench.

Anchor characteristics of UnribbedThreaded Anchor Rod:

1. superficially it restricts the rock and soil frame from the unique body.

2. macroscopically it will increase the cohesion of the rock and soil body.

3. Anchor rods are not only used in mines, but also used in engineering technology for active reinforcement of slopes, tunnels, dams and so on.

4. Anchor is the basic component of tunnel support in contemporary underground mining, which binds the perimeter rock of the tunnel together, so that the perimeter rock supports itself.
