During construction of rock anchor, there are several guiding principles being insisted on.
1. Construction of anchoring and shotcreting engineering should conform to demands of safety applicability, advanced technology, economical rationality, quality guarantee and environment protection.
2. Implement national technological economy of energy conservation, low carbon and ecological environment preservation.
3. Protection and utilization of self stability capacity and self intensity of rock and earth mass maximally.
4. It should have wide covering surface, which can guide design and construction of all kinds of anchoring and shotcreting engineering, such as tunnel caverns, slope, foundation pit, anti-floating and concrete dam, etc.
5. It should adopt mature new concept, new technique, new material and new crafts.
6. Integration with international advanced standard of the same kind.
