Product Description

Product Description

                                                                                                   Split Set Rock Bolt

1. High strength: Split set rock bolt is made of high-strength steel pipe, which has high tensile strength and bending strength and can with stand large loads.

2. Good stability: The split set bolt is fixed in the formation by anchoring technology, which can effectively enhance the
stability of the formation and prevent the formation from sliding and collapsing.

3. Convenient construction: Split set rock bolt construction is simple, does not require large mechanical equipment, only need drilling, grouting and anchoring and other simple processes can be completed.

4. Wide range of use: Split set rock bolt is used in various geological conditions, including weak strata, karst strata, fault zones, etc., which can meet the needs of different projects. Under the expansion of the center, the application range of pipe joint bolt is also expanding. With the acceleration of the urban process, the utilization of underground space is more and more extensive, and the application in underground engineering is also more and more extensive. For example, in the subway, tunnel, underground shopping malls and other projects, pipe joint anchor can be used for formation reinforcement, tunnel support, underground space separation and other aspects, in addition, in mining, water conservancy, highway and other fields, pipe joint anchor also has a wide range of applications.

As an efficient, stable and convenient geological support material, split set rock bolt has a wide application prospect. With the continuous development of technology and the continuous expansion of application scope, it is believed that the position of pipe joint bolt in the field of geological support will be more and more important.

Product Usage
1. Determine the anchor bolt hole position according to design requirements and drill holes using drilling tools.
2. Blow out the rock powder inside the hole with compressed air.
3. Install an anchor plate on the rod and use an impact drill to drive the anchor rod into the hole.
Recommended calculation method for drilling hole diameter of pipe joint anchor rod:
In rock layers: borehole diameter=(0.9-0.95) x anchor rod diameter
Anchor rod drilling depth: Anchor rod length+100mm, drilling deviation rate < 1%
In coal seams: borehole diameter=(0.9-1.00) x anchor rod diameter
Anchor rod drilling depth: Anchor rod length+200mm, drilling deviation rate < 1.5%
