Product quality is the cornerstone of brand value. Quality reflects the technical content and culture of an enterprise, and represents the credibility and image of an enterprise.
Rock Bolt is one of effective supporting methods to reinforce foundation of civil construction. It relies on bonding strength between soil layer and rock bolt structure to provide bearing capacity. It is widely applied in engineering structures which needs stress to transfer in stable soil body.
The fundamental principle of geotechnical anchoring is to transfer tension of structures or keep self stability of excavation face in stratum, relying on shearing strength of self drilling rock bolt’s surrounding stratum.
As self drilling bolt’s raw material, seamless steel tube’s quality must be completely inspected according to product standard and technical specification. Specific inspection includes steel tube’s chemical component analysis, geometric dimension inspection, surface quality inspection, physical and chemical properties inspection, processing property inspection, metallographic analysis, thread inspection and measurement. The purpose is to ensure quality of steel tube and meet relevant standard code or technical condition requirement.
During tunnel construction, deformation often happens. Observing from tunnel surface, there are cracks, shedding phenomenon or underground water dropping appearing. If reason doesn’t get analyzed and maintained timely, worse deformation will happen.
