In the construction of slope protection, why must be self drilling hollow anchor bolt? There are some reasons in below:
1. Integration of drilling, grouting and anchoring as a whole. Self drilling hollow anchor bolt can ensure the anchoring effect in complex ground conditions. It has the features of safety, reliability and efficiency.
2. Rapidly initial support, control the deformation and ensure the stability of surrounding rock.
3. The hollow design makes the anchor bar achieve the function of a grouting pipe, thus avoiding the loss of mortar caused by the grouting pipe in the traditional construction process.
4. The grouting is full. The pressure grouting can be realized to improve the quality of the project.
5. Due to the role of the accessories, the hollow bar can be well placed in the middle. The mortar can cover the hollow bar in full length, avoid the risk of corrosion, and achieve the purpose of long-term support.
6. Easy installation. It’s easy to place the plate and nut without processing thread on site.
7. Combined with the matched grouting pump and grouting technology, at present, self drilling hollow anchor bolt is the only anchoring system to solve the problems of traditional anchoring support in China.
