Sinorock self-drilling hollow bar system which mostly common used in radial bolting,fore poling,soil nailing,tunneling,underground mining and ground engineering industry.It is manily used for the supporting enineering in thre loose and broken rock stratal with difficult to drilling hole.It provides the effetive solution for micro-piling,rocknetting retention and tunnel repair and refurbishment.
Sinorock has R&T thread self-drilling hollow bar.Comparing to R thread anchor bolt system, T thread anchor bolt has a different thread bar. It will meet more demands in projects. Similar to the suitable projects of R Thread anchor bolt, T thread anchor bolt is also used for geotechnical engineers, such as tunneling, mining, hydroelectric and civil construction.
T thread anchor bolt is a kind of Stainless hollow anchor which can resist corrosion in air or chemical corrosion conditions.
It applies to marine environment and chloride corrosion conditions. It is also used for chemical industry and infrastructures of important equipment which requires high anti-corrosion quality. Meanwhile, T thread anchor bar can meet the demands of anti-corrosion and seismic resistance, which can reach 120 years without maintenance. It’s widely used in bay, pier, pile foundation, breakwater and mooring system.
