Sinorock ISO different types of mining anchor bolt

The self-drilling mining anchor bolt

The self-drilling mining anchor boltis used to stablize unstable soil formation.The unconsolidated or weathered ground conditions favor this technique for fast and simple method of installation compared to the traditional method.

We can produce all kinds of self-drilling mining anchor bolt,such asR25N,R32L,R32N,R32S,R38N,R51N,R51L,T76N and T76S.

and we can make special rod, plate,extension coupling, nuts according to your request.

It can be galvanized,epoxy or galvanized epoxy double-handling to meet the different corrosion resistance requiements.

Thread bar anchors

Thread bar anchors are generally used to:

1. Anchor support structures for excavations such as sheet pile walls, soldier piles and lagging, drilled piles and slurry walls

2.Counteract uplift forces in structures subjected to buoyancy and lateral loads

3.Transfer external forces to the ground; e.g. wind, earthquake

4.Stabilize eccentrically loaded foundations

5.Stabilize material or excavated slopes.

Features

1.Simple and rugged

2.Positive anchorage

3.Easy to Splice

4.Corrosion Protect System

a:Hot-dip Galvanizing Corrosion Protect. We can do it according to EN ISO 1461.

b: Duplex Coat System:Duplex Coat = Hot-dip Galvanizing + Epoxy Power Coating

Swellex mining anchor bolts

Swellex mining anchor bolts are extremely versatile and can be used in various tunneling and mining systems.

An application in tunneling is to use Swellex as pattern bolts to support an excavation. The bolting pattern depends on the size of the excavation and qualities of the rock mass.

In mining, common applications like roof and hanging wall bolting have adopted Swellex as a rapid, safe and high-performance device.

With various capacity ranges (120 KN, 160 KN, 240 KN)the Swellex anchor bolts can be used in most reinforcement and support applications. They can also be used either in mines or in civil engineering applications, and their specific mechanical properties will provide the requested safety and performance.

Fiberglass anchor Bolts

Compared with aluminum or steel, glass fiber reinforced plastics (GRP) have advantages that can be traced to the properties of the composite material: High resistance to corrosion and higher specific strength. Depending on the application and at constant load, a GRP bolt can yield a high weight reduction.

The application of glass fiber reinforced plastics (GRP) offers various possibilities. In cooperation with FiReP International AG (Switzerland), Sinorock offers a range of GRP bolts that are manufactured using the latest technologies. The material offers high mechanical solidity and favorable long-term behavior for anchor technology.

Friction anchor Bolt

Sinorock’s Friction anchor Bolt improves rock stability and safety factors by tightening as lateral strata movement occurs. The Friction Bolt is primarily used in metalliferous mining operations, but is also well suited for rib support in coal operations. Sinorock’s Friction Bolt is availablein three sizes:33mm,39mm and 47mm.
