Hollow Self Drilling Anchor R51N Diameter 51mm , High Efficiency
Anchor bolt
Anchor bolt means a rod that transfers the structures or geotechnical load to a stable rock formations, i
t consists of rod, drill bit, coupling, plate, grouting stopper and nut. It has been widely used in tunnling,
mining, slope stabilization, tunneldiseases treatment and roof supporting of undergroundworks. It is for
loose ground(clay, sand friable etc.) Hollow anchor rod is made of seamless tube with high strength.
Features of Hollow Grouting Anchor Bolt:
Hollow design, implement the grouting tube function, avoid the mortar loss when the traditional grouting
tube pulled out.Grouting full, and can achieve the pressure grouting to improve project quality.
Center is good, mortor can wrap the bolt body together, so that it can avoid corrosion to achibe along term
supporting purposes.
Easy installation, without onsite processing of threads. It can be easily installed an plate, nut.
Selt-Drilling Anchor Bolt Description
