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
It may bodies drilling, grouting and anchoring as a whole.
It has a wide specifications. Diameter:25-130mm.
Qucik and easy construction, high efficiency.
Used invious surrounding rocks.
Features
■ The tendon simultaneously serves as a drill rod
■ Extremely fast installation because borehole drilling is made redundant by simultaneous drilling and grouting
■ System can be installed in confined spaces utilizing simple and compact drilling equipment
■ Variable anchorage and angle compensation designs
■ Irregular grout body enhances capacity
■ Drill bits are available for various ground conditions
■ Can be used as a so
Fields of Application
■ Slope, embankment and rock stabilization
■ Shoring and excavations
■ Fixation of rock fall mesh
■ Avalanche barriers
■ Foundations
