Key Attributes
Anchor bolt refers to the long and thin rod body that goes deep into the rock and soil and controls the deformation of the rock and soil, and can include the cushion plate, nut and other components.
Specification
- Definition
The bolt body is a grouting pipe, which can not only anchor the bolt body after pressure grouting, but also play a role in strengthening the surrounding rock when the grouting pressure is large. The upturn hole shall be provided with a stop plug and an exhaust pipe.
- Effect
1. Rapid initial support, control surrounding rock deformation, ensure the stability of surrounding rock.
2. The hollow design makes the anchor bolt realize the function of the grouting pipe, avoiding the loss of mortar caused by the traditional construction process when the grouting pipe is pulled out.
3. Full grouting, and can achieve pressure grouting, improve the quality of the project.
4. Due to the role of various accessories, the residence neutrality of the rod body is very good, and the mortar can wrap the full length of the anchor rod body, avoiding the danger of rust and achieving the purpose of long-term support.
5. Easy installation, no need to process threads on site, you can easily install the plate and nut.
6. Combined with the supporting grouting pump and grouting technology, it is the only anchoring system in China that completely solves many problems of traditional anchoring support.
- Usage
It is mainly used for system support of surrounding rock with medium good geological conditions.
In the case of hard rock, horizontal bedding, joint fissure opening and mud inclusion or groundwater development, the initial support can be formed quickly by steel expanded shell bolt to control the deformation of surrounding rock and ensure the stability of surrounding rock, and then the permanent anchorage by grouting. After drilling the hole with the rock drill to the design depth of the anchor rod, the steel anchor head is installed on the anchor rod body, placed in the hole, after installing the grouting plug, the backing plate and the nut, the anchor rod is reversed to make the expansion shell anchor head expand and grasp the hole wall, and then grouting is carried out.
