Hollow anchor bar means a rod that transfers the structures or geotechnical load to a stable rock formations, anchor bolt consists of rod, drill bit, coupling, plate, grouting stopper and nut. Widely used as an efficient anchoring means, in tunnel pre-support, slope, coast, mine, water conservancy projects, building foundation, roadbed reinforcement and geological diseases treatment such as landslip, crack, sink age. It`s irreplaceable in narrow construction environment. Hollow anchor bar is made of seamless tube with high strength.
Advantages and Characteristics :
1.No casings required, because anchor bars can be drilled into loose soils without needing casings to support the boreholes.
2.Fast drilling and installation, because drilling, installation and grouting are in a single operation.
3.Both rope threads and trapezoid threads are robust and ideal for rotary-percussive drilling and ensuring a high level of bond with the borehole gout.
4.The hollow core not only serves for flushing during drilling, but also for grouting after drilling.
5.Continuous threads ensure the bars can be cut and coupled at any point, or extended.
6.Different anchor bits are available for different ground conditions.
7.Duplex anti-crossin process, hot-dip galvanized and epoxy coating system.
