Rock Anchors With The Most Complete Specifications

Swellex Rock Bolt Description

Swellex Rock Bolt is a commonly used underground engineering support equipment, which is mainly used to reinforce and stabilize the rock body.Swellex Rock Bolt consists of an expandable spiral steel tube, which is usually used in underground tunnels, ramps and mines. The device effectively reinforces the rock mass and improves the stability of the supporting structure.

Features of the Swellex Rock Bolt include:

1. Expansion capacity: Swellex rock bolts expand during installation by injecting liquid resin or cement slurry to form a strong support structure and enhance the stability of the rock body.

2. Convenient installation: Installation of Swellex rock bolts is relatively simple and quick, without complex equipment and technology, and the support work can be completed in a relatively short period of time.

3. Wide range of application: Swellex rock bolts are suitable for different types of rocks and geological conditions, and can meet the needs of various underground engineering support.

4. High load-bearing capacity: After expansion, Swellex rock bolts can withstand large tensile and shear forces, effectively supporting the rock body and preventing rock debris from falling and rock slides.

Overall, Swellex rock bolts are a reliable support material for underground construction, widely used in tunnels, mines and other underground projects, providing an important guarantee for the safety and stability of the project.

Sewn tube anchor product features:

1、Raw material adopts high strength alloy strip steel

The pipe slit anchor is installed in the drill hole which is a little smaller than the pipe diameter, at this time, three kinds of forces will be exerted on the surrounding rock one is the radial pressure on the hole wall within the full length of the pipe slit anchor, one is the friction force to stop the surrounding rock from sliding down, and another is the bearing force of the pipe slit anchor pallet tray plate, which makes the surrounding rock more stable.

2、The installation of pipe slit anchor is simple.

3、High friction force of pipe slit anchors.

The technical requirements of sewing tube anchor rods are as follows:

1. Surface requirements: the surface of sewing pipe anchor rod should be flat and free from serious strains and rust. The weld should be free of cracks, pores and slag clamps, and there shall be no burning through the pipe wall. The pallet should be able to move freely on the rod. The mutual misalignment between the interface of the retaining ring and the opening of the pipe seam is appropriate between 1700-1900.

2. Strength requirements: the pull-off force of retaining ring weld should be not less than 80kN, and the ultimate tensile force of the rod body should be not less than 110kN. the initial anchoring force should be more than or equal to 25kN/m, and the load bearing capacity of the pallet should be not less than 65kN. these technical requirements ensure that the interface of the anchor rod is strong and can withstand a certain amount of tensile force and load bearing capacity.

The following steps need to be followed when installing and using a sewing tube anchor:

1. Drill anchor rod holes in the top plate using an air drill.

2. Sleeve the tray into the anchor rod body.

3. Use the wind hammer to drive the anchor rod body into the pre-drilled anchor holes to ensure that the tray is compacted with the roof gang band.

4. When choosing anchor rods for use, users should refer to the technical requirements of retaining ring weld pull-off force and ultimate tensile force of rod body mentioned above, and at the same time, according to the specific conditions of the rock on the site, choose the appropriate drilling diameter in accordance with the method stipulated in the GBJ86 standard.
