Cable Bolt Bulbed

Key Features

• Manufactured from stress relieved, low relaxation, high strength 15.2mm diameter 7 wire steel strand, the cable bolt is formed by bulbing the strand into small cages, typically 26 to 28mm diameter, and up to 6 bulbs per metre.
• The cable bolt bulbs can be modified, in frequency and diameter, so that geotechnical engineers are able to design specific reinforcement products to suit ground conditions being encountered. In some cases, de-bonding tube can be added to the lower section of the bolt to allow for pre-tensioning.
• The bulbed cable bolt is supplied in either single, double or in combination forms. Single bulbed plus single plain cable. They are supplied in nominated lengths for grouting into holes from 35mm to 105mm diameter.
• Can be used with cementitious grouts as well as resin anchors when early support is required.
• For up hole applications, cable bolts are fitted with a spring wire “fish hook” to hold the cable bolt up the hole.
• Surface confinement is provided by flat or domed plates and barrel and wedge anchors. Please refer to appropriate pages for slotted or multiple hole plates, barrel and wedge anchors, grout and breather tubes.
