After decades of growth and development, industrial and civil buildings all over the world are entering a phase of gradual deterioration and aging, the demand for improved safety of existing in frastructure has rapidly increased. This is particularly the case in China. The result increasing in the threat to safety as well as concerns about reliability has led to such building structures requiring continuous maintenance and repair. In seismic regions, such as south-western China, the structural deficiency of existing constructions are particularly acute problem, because of lacunae in construction knowledge and the design code. To accomplish complex drilling tasks like tunneling,grouting or slope stablization,Self drilling hollow rock bolt is utilized for efficient performance.Our production of rock bolt has increased progressively to cover the national markets due to the competitiveness level reached by our company after both the metal treatment technology innovation and the experience made in the field during these past years. In addition, as concrete structures become more complex, the self drilling hollow bar systems used to connect steel to concrete and concrete to concrete add to the problem. This had made it necessary to demolish aging buildings and to reconstruct them in a structurally satisfactory manner. Use of the Sinorock’s self drilling hollow bar System for the Stabilization of your construction.As an important form of reinforcement in geotechnical engineering, Sinorock self drilling hollow bar System supporting is safe, effective, and economical, etc.
