Friction Stabilizer Split Set
Also known as friction rock stabilizer, the split bolt is a new type of anchor that fully anchors the rock and actively strengthens the surrounding rock, its three-dimensional part is a longitudinally slit high-strength steel pipe. These come in the following sizes; 33mm, 39mm, 42mm and 47mm. other technical details available on request.
- High –strength alloy strip steel,
- The easiest to install
- No anchoring agent required
- The friction between the anchor and the rock mass is large
- High shear and tensile strength
- Equipped with a high-strength tray, the tray is evenly stressed
- The roadway height is greater than the bolt length.
In underground mines
Every kind of underground mine uses Split Set Friction rock stabilizers for ground support. Miners also use them to pin mesh, hang conveyors, hold pipes and cables, secure rails in place, and for other needs.
In tunnels and other excavations
Split Set stabilizers have solved many problems for contractors in constructing and maintaining railway and road tunnels, hydro power tunnels, powerhouse and storage caverns, shafts, water and sewage tunnels and others.
And above ground
Open pit mine and quarry operators use them to stabilize high walls. Contractors find Split Set stabilizers ideal for attaching screen to control spalling on cuts.
Self-Drilling Rock Bolt
Self-drilling anchor (SDA) combines drilling, insertion and grouting into one easy operation. It reduces project lead time and installation difficulty.
Low carbon content in steel increases its ductility, reduces its brittleness, and resists corrosion cracking and carbon embrittlement. This choice of material significantly reduces occurrences where rock bolt may snap or buckle during onsite installation.
As an effective means of anchoring, self-drilling anchor bolt can be widely used in advanced support, radial support, slope reinforcement, roadbed reinforcement and tunnel disease control.
- Ball nut: it can transfer the stress of surround ding rock to the pad.
- Arch plate: can bear greater stress of surrounding rock.
- Check pulp plug: make the grouting maintain a certain pressure to fill the surrounding rock gap adequately.
- Anchor bolt bar: the whole length of the international standard waveform connection thread, easy to install drill bit, coupling sleeve, fastening nut; and can be arbitrarily cut and connected to lengthen.
- Bushing: so that the bolt can be lengthened to the design depth while drilling.
- Broach: it has strong penetrating power, enabling the bolt to pass through all kinds of rocks.
Self-drilling bolt adopts good thick wall seamless steel pipe material, perfect and fast surface screw forming technology and well-made fittings, the function of drilling, grouting and anchoring has been realized.
- They have a strong penetrating drill in front of the bolt, under the action of general drilling machinery, it can easily penetrate all kinds of rocks.
- The bolt has a continuous international standard corrugated thread, which can be used as a drill pipe to complete the drilling of anchor hole.
- The bolt body as the drill pipe does not need to be pulled out, and the cavity can be used as the grouting channel from inside to outside.
High efficiency grouting stopcock enables grouting pressure, fully fill the vold and fix the fractured rock mass, high strength washer and nuts can transfer the stress of deep surrounding rock evenly to surrounding rock, the purpose of mutual support between rock and anchor is achieved.
Size: 18mm x 2m and 16mm x 6m
Rock bolt is the most basic part of roadway support in contemporary coal mines, it reinforced the surrounding rock of the roadway, make the surrounding rock support itself.
The non-longitudinal ribbed steel resin anchor bolt is a kind of bolt made by the spheronization process. The strength of the thread segment is greater than the strength of the body, and the thread section has good bending and shearing performance. It is a new type of anchor bolt with high strength support in the roadway.
- Available in left hand of righthand thread.
- Higher thread ribs mix resin better and improve anchorage
- Suitable for using with either resin cartridges or cement grout
- Equal strength on the entire length
- Due to continuous thread on entire length
- The nut can be fastened upward at any place
- Increase the material utilization ratio and save cost
- Available in black or hot dip galvanized
