Alloy R38N Steel Anchor Bolts Self Drilling Hollow Grounted Length
1m - 8m
Anchor bolt
Anchor bolt means a rod that transfers the structures or
geotechnical load to a stable rock formations,
it consistsof rod, drill bit,coupling, plate, grouting stopper and
nut. It has been widely used in tunnling,
mining,slope stabilization, tunneldiseasestreatment 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
